Release of harmful substances from building materials. Which concrete is not harmful?

The walls of our home should protect and protect us from danger. In what cases does the house begin to be dangerous for us and our loved ones?

There can be more than 100 toxic substances in the air of an apartment. After cosmetic repairs, we can worsen the radiation background in our apartment. Not only varnishes and paints can be dangerous if vapors are inhaled, but also ordinary linoleum or chipboard furniture.

Today I want to dwell on the topic “Harmful Construction Materials, poisoning our body." Let's figure out what building materials are distinguished hazardous substances and we will try to replace them with safer ones.

The most harmful building materials

Highly toxic substances benzene and ethylbenzene enter our apartment from building materials - linoleum, varnishes, paints. These substances cause cancer.

Large concentrations of harmful chemicals - xylene and toluene, which are found in varnishes, paints, plastics, linoleum, can cause damage to the skin, mucous membranes, and pulmonary diseases.

The presence of such poisons can be found in the air of any apartment. Phenol is used in production synthetic resins and various chemicals.

Phenol is found in:

varnishes and paints;
linoleum;
furniture made of fiberboard and chipboard;
bitumen and tar impregnation;
roofing felt.

No one thinks that phenol poisoning not only affects the liver and kidneys, but also changes the composition of the blood.

Another harmful substance is formaldehyde, which is contained in chipboards and fiberboards, polystyrene foam, and plywood. Its concentration is very high in apartments where there is furniture made of chipboard.

Formaldehyde is the most common pollutant and carcinogen. If it enters the human body, headaches, nausea begin, and the upper respiratory tract is affected. Let's stop using such harmful materials.

The most harmful finishing materials

Styrene is a dangerous substance, the vapors of which irritate the eyes, cause headaches, nausea, dizziness, and spasms.

It contains:

facing plastic;
polystyrene thermal insulation foams;
moisture-resistant wallpaper.

Expanded polystyrene panels constantly emit gas and should not be used in residential areas. Polyvinyl chloride emits vinyl chloride, which affects the nervous system. This process is enhanced by heating. If the linoleum is located near the radiator, it heats up and vinyl chloride is released faster.

Building materials such as phosphogypsum and sand-lime brick can be a source of radon, a radioactive gas that is a product of the decay of radium. The radiation dose from poisonous radon is even greater than the dose from other radiation sources.

Therefore, it is necessary to intensively ventilate the room.

When you choose materials for renovation, try to pay attention to environmental friendliness. Parquet is best for the floor. Linoleum is more harmful, it is better not to lay it in the nursery and bedroom, stop with laminate.

In children's rooms, do not use foam plastic as insulation; replace it with natural materials.

When choosing paints, choose water-based, alkyd, latex or polyester. They dry quickly and there will be no dangerous fumes in the air.

Products made from polystyrene foam and polystyrene are very harmful. A huge number of people decorate their ceilings with polystyrene foam tiles and other thermal insulation materials made from polystyrene foam. Remember, they are very toxic.

Replace polystyrene foam tiles with safe mineral wool tiles, which are also excellent insulation.

Sealants are unsafe and contain a foaming agent. Remember a strong smell is always a sign of toxicity of the sealant.

Very harmful adhesive mastics for gluing tiles or linoleum, which contain a solvent.

Plastic double-glazed windows are also not harmless; polyvinyl chloride frames and profiles emit many toxic substances. It is always better to opt for wooden frames.

Harmful materials in kitchen utensils

Also pay attention to kitchen utensils, it can also be made from harmful materials. Melamine products are especially dangerous here. Melamine is a brightly colored plastic that releases formaldehyde.

Even crystal can be dangerous, because as it turned out, it is a source of weak radioactive radiation and emits lead. Therefore, it is not recommended to use this cookware frequently. You cannot keep drinks in a crystal decanter for a long time. If left in crystal for a long time, the compote can absorb lead. Therefore, pour drinks into crystal glassware immediately before serving.

Oxidized aluminum pans can cause harm, and are especially dangerous for people with kidney problems. Do not scrub aluminum cookware until it shines metal sponge. An old pan coated with an oxide layer may not be beautiful, but it no longer oxidizes.

Our beloved teflon frying pan contains many toxic substances that end up in food. The more often we heat a frying pan, the faster the coating is damaged and poisons enter the air. The released Teflon particles enter the lungs and damage cells. All workers at enterprises producing Teflon products wear masks.

Vapors released from Teflon increase the risk of diabetes, obesity, and cancer.

Old Cast-iron pan the best and safest. Ceramic-coated frying pans are also considered environmentally friendly.

What can replace harmful building materials?

The safest floor covering is parquet and cork covering. Choose them for children's rooms. Cavrolin does not emit hazardous substances, but can cause allergies.

Laminate flooring may release toxic substances. Linoleum is the least environmentally friendly material.

Which insulation to choose? Expanded clay is safe, but not effective. Glass wool is effective, but may sag over time. Polystyrene foam and expanded polystyrene are durable, but when heated they can release poisons and do not remove vapors well from the room, forming fungus and condensation.

Stone wool perfectly protects against heat and cold, is safe and recommended for residential premises.

When choosing wallpaper, choose paper wallpaper, glass wallpaper, vegetable wallpaper based on jute, golden flower, bamboo or reed; they are made from natural ingredients. It is better to choose wallpaper glue based on starch or casein.

When choosing materials for repairs, pay attention to:

quality certificates;
pungent odor, products should not be a source of pungent odor;
products from well-known companies, they are more reliable.

The most harmful materials are varnishes, paints, poor quality mastics, linoleum, vinyl wallpaper, decorative film. Discard them and do not use them for repairs. When choosing building materials, pay attention to sanitary and epidemiological conclusion.

Not all building materials are as safe and environmentally friendly as manufacturers advertise. As a result, modern housing is overloaded with toxic emissions, and people are increasingly suffering from diseases of the respiratory and endocrine systems and do not understand why the disease overtook them.

We bring to your attention a list of the most unhealthy building materials. After all, forewarned is forearmed, and in our time, any product must be chosen as carefully as possible, because your health is at stake.

1. Polymer materials. The danger lurks behind the abbreviations chipboard, PVA, PVC, fiberboard; such materials are used everywhere: for waterproofing, thermal insulation, sealing, finishing works, in production carpets and furniture. And if only a carpet or a plastic window does not cause any particular harm, then if a large number of objects are concentrated in the room, the human immune system simply cannot stand it. Budget furniture is most often made from chipboard and fiberboard, linoleum, plinths, pipes are made from PVC, Wall panels, windows, profiles and so on. PVA is present in carpets and synthetic coverings. Unscrupulous manufacturers who use cheap materials are ruining our health, because over time, such interior items begin to release dioxin - a powerful carcinogen that can lead to cell mutation and the development of tumors. Bad linoleum releases benzene and ethylbenzene, toluene, chipboard - formaldehyde, these compounds are dangerous to humans.

2. Expanded polystyrene and asbestos. These materials can also be called safe at a stretch. Expanded polystyrene is used to insulate industrial premises; it is better not to choose this material as insulation for a home. Asbestos also begins to release carcinogens over time: asbestos fibers penetrate the body through the respiratory tract and are deposited there. Mineral wool is no less harmful: tiny particles enter the air, which also easily end up in our lungs. If walls are insulated with this material, it is better not to break it or drill it, and if necessary, completely change the insulation layer.

3. Sand-lime brick, phosphogypsum. It would seem that these are popular building materials, but they also pose a hidden threat. IN sand-lime brick Radon may accumulate - this inert gas is radioactive and can cause lung cancer. Reinforced concrete is also not the best choice, it can shield electromagnetic radiation, and unscrupulous builders sometimes use rocks with a high radioactive level in concrete, so one can only dream of comfort in such a structure. And this is not counting the fact that over time, radioactive gases thorium and radium begin to be released from such reinforced concrete.

4. Polyurethane foam. Insulation, friezes, moldings, sockets and other products are made from it. Polyurethane is a gas-filled plastic, during the production of which it emits carbon dioxide and polyol. It is believed that polyurethane foam is quite stable, but it cannot be used in large quantities, especially if the premises are residential. Warming is carried out with outside home or apartment to avoid harmful fumes.

5. Expanded polystyrene and polyurethane. Over time, such insulation begins to release toxic compounds - isocyanates; styrene is also released from the foam - a toxin that has a harmful effect on the cardiovascular system. In addition, such insulation can accumulate toxins, so they are suitable only for exterior decoration.

6. Synthetic adhesives and varnishes. These materials are especially harmful to pregnant women and children; they can cause allergic reactions and illnesses. respiratory system. Many synthetic varnishes contain toluene and xylene - when evaporated, these substances irritate the mucous membranes, penetrate into the lungs, and then accumulate in the body. Some types of parquet glue and varnish, which are based on toluene or acetone, can cause miscarriage or female infertility.

7. Plastic panels. In fact, plastic is harmful in almost all forms, but most of all it is harmful plastic panels are harmful to health if they are used in a room where high temperatures reign: for example, a kitchen. Heat contributes to the release of toxic dioxin, the same applies to low-quality plastic windows, so best option for finishing with plastic - a corridor or hallway, but not living room and not the kitchen.

8. Cheap paints. Low-quality paints and mastics contain the lion's share of harmful compounds: lead, copper, cresol, toluene, xylene and others. After six months of service, the paint begins to deteriorate and release polyvinyl chloride - this component has a destructive effect on the digestive, excretory and nervous systems. It is better to choose for painting rooms water-based paint well-known manufacturers, with a quality certificate.

9. Washable wallpaper. Basically, such wallpaper is chosen for the kitchen or hallway; it is dense, easy to clean, and resistant to stains, but there is also a downside to this coin. Such products cannot be called environmentally friendly. Washable wallpaper contains various mastics, so the scope of application is limited. In addition, over time, styrene begins to be released - a substance that irritates the mucous membrane of the nasopharynx and can cause respiratory diseases.

10. Vinyl wallpapers and linkrust. The content of vinyl chloride mastic and other substances that are not very beneficial to health limits the scope of application of such wallpaper. Optimal choice for residential premises - paper, jute, bamboo wallpaper, as well as textiles. It is better to avoid synthetic threads and vinyl - this a good choice for the hallway, but not for the bedroom or nursery.

How to protect your health?

First of all, pay attention to the presence of a quality certificate and a sanitary-epidemiological conclusion. Self-respecting manufacturers test their products in laboratory conditions to ensure they are safe and meet standards.
The material should not emit an unpleasant, distinct “chemical” smell; this is the first confirmation that toxins are being released.
Buy materials in specialized stores; markets are unlikely to provide you with quality certificates. Analyze information about the manufacturing company, read reviews, since they can be found in abundance on the Internet;
Ventilate living areas more often and do wet cleaning regularly.

Eco-labeling

Be careful when choosing construction and finishing materials, because saving can cost you dearly, no matter how pretentious it may sound.

Analyzing information about porous building materials, one may come across the opinion that aerated concrete is harmful to health. Of course, the easiest way is to dismiss such statements as idle fiction, but it is still better to analyze the composition and take into account all possible risks.

It is this issue that we will devote our article to.

We need to figure out whether this material can be used in housing construction!

Analysis of aerated concrete

To understand whether aerated concrete is harmful to health, you need to analyze its composition and production technology:

The basis of the material is cement mortar with the addition of sand and lime.
During the preparation of the solution, granular or paste-like gas-forming additives are introduced into the cement-sand mixture. Reacting with water, the aluminum component of these additives releases gas, which forms a system of pores inside the material.
To improve the mechanical properties of aerated concrete, slag or ash can be added to it.
After the reaction is completed, the mixture is first subjected to primary hardening when heated, then the finished blocks are sawn and autoclaved, treating them with heated steam.

Industrial block production

Actually, other cellular concretes are produced according to a similar scheme.

True, in technological processes there are also differences:

For example, to make foam concrete, instead of an aluminum composition, a synthetic or protein foaming agent is added to the solution.
And in the production of polystyrene concrete, the cellular structure of the material is formed by polymer granules, which are made from waste construction or packaging foam.

Polystyrene filler is quite toxic when burned

Of course, the instructions for making these materials contain many other nuances not mentioned here, but we are primarily interested in the composition. Now let’s try to analyze which components of aerated concrete can affect human health.

Harmful or not? For health

The negative effects of the material are usually divided into two aspects:

Risk of human poisoning upon contact or prolonged stay in the room.
Destructive influence on environment.

We will try to consider both aspects in sufficient detail, and we will start with the one that is “closer to the body.”

So, is aerated concrete harmful to health?

First, you need to pay attention to the base. Cement and sand, which are in a bound state, do not affect our body in any way. So there is definitely nothing to be afraid of here.
Lime also usually does not raise any questions, especially since after autoclaving almost all of it goes into an inert state.

Note!
Materials with a high lime content are significantly hygroscopic, so they should be protected from contact with water.
However, this is only relevant for situations when we fill cellular concrete do it yourself: industrial designs usually do not have this drawback.

Next are gas-forming additives, which, in fact, are considered one of the risk factors. But here, too, everything is in order: firstly, aluminum, which provides gas release, is non-toxic, and secondly, during the hydration reaction, ordinary hydrogen is released.

Gas-forming additive based on aluminum hydroxide

We still have additives, and this is where we need to be very careful. The thing is that both ash and slag can have very different origins, and therefore it cannot be ruled out that they contain heavy metals and toxins (lead, arsenic, etc.). Of course, their share in the material will be negligible, but in any case this should be avoided.
The way out of this situation is quite simple: you need to purchase gas blocks from certified manufacturers. Yes, the price will be a little higher, but you can be sure that all components have undergone radiological and toxicological testing before entering the solution.

Slags and ash may contain heavy metals

It is also worth saying a few words about other types of porous concrete:

Foam concrete does not contain anything that can have bad influence on our body.
But the question of whether polystyrene concrete is harmful to health is quite complex. The material itself is absolutely safe, but with strong heating there is a risk that the polystyrene granules will begin to melt, releasing toxic gas. However, this material is classified as non-flammable, so the risk of such a situation occurring is minimal.

It is also necessary to remember that the open pores of such materials can be colonized by fungi or pathogens. To avoid this, it is necessary to maintain a minimum level of moisture in the masonry, but here it is enough to follow the technology of construction and finishing of structures.

The masonry should be protected from moisture, as shown in the photo

For the environment

Separately, it is worth discussing the impact of the material on the environment. Here the radiation characteristics of concrete come to the fore.

Note!
There is no need to be afraid of the word “radiation” in this context.
Even the most natural composition has a natural background: it is due to the presence of trace amounts of elements such as radium, thorium, potassium, etc.

You can compare the radiation hazard of different building materials using the table:

As you can see, the radiation hazard indicator of such blocks is minimal, which allows us to classify it as a first class material in terms of this parameter.

From the point of view of radiation hazard, the material is harmless

Other advantages of aerated concrete from an environmental point of view include:

Absence from the lineup synthetic materials(phenols, resins, polymers).
Low flammability even with direct influence open flame.

Note!
When a gas block is heated, no toxins are released into the atmosphere.
The hydrogen contained in the pores is simply oxidized to water, which immediately evaporates.

A stable structure of the material, ensuring extremely slow decomposition during disposal and inclusion in the natural cycle of the cycle of elements. Aerated concrete is quite inert, therefore, when it gets into water or soil, it does not poison them with decay products.

Of course, it is necessary to study information about whether foam concrete, aerated concrete, etc. are harmful to health. However, we should not forget that most “horror stories”, when thoroughly checked, turn out to be not confirmed by factual material, and real threats are quite easy to deal with. This issue is covered in more detail in the video in this article, so we recommend that you watch it very carefully.

The potential harm of cement lies in the presence of asbestos in it. Asbestos dust (powder) is extremely dangerous if it enters the respiratory tract. However, you can only experience real health problems from this component if you breathe asbestos dust on a regular basis, for example, while working in a cement plant.

Concrete is harmful to health

Now let’s find out why concrete began to be considered radioactive. The fact is that not all clinker manufacturers use high-quality raw materials. In nature, all materials emit radiation, it is within certain limits and is considered acceptable. But if excavation When the extraction of raw materials for clinker is carried out in quarries, for example, contaminated with radioactive waste, the cement obtained from it will, accordingly, “foul”.

Rating of the most harmful building and finishing materials for humans

It has long been known that many diseases are a product of human living conditions, the environment of which does not at all meet the sanitary standards of living. At the same time, housing is not necessarily dirty or damp, it simply contains too many sources that emit harmful substances, the concentration of which is several times higher than permissible standards.

10 building materials hazardous to health

During construction monolithic structures apply the method of filling the seal concrete mixture. The base used is fine crushed stone, which is obtained from durable rocks (for example, granite). Not too conscientious construction companies At the same time, they do not bother checking the safety of the sealant, in particular its radioactivity. As a result, residents often move into apartments whose walls create an increased radioactive background for many decades.

Concrete is harmful to health

The most unhealthy building materials

Linoleum. The cheapest flooring. Bad linoleum pollutes the air with benzene and ethylbenzene, and they can cause cancer and blood diseases. Substances such as xylene and toluene are also released - in high concentrations they also lead to diseases of the blood, lungs and skin, and affect the mucous membranes. Carcinogenic vinyl chloride affects the nervous system. Finally in conditions ordinary apartment polymers - namely, what linoleum is made of - break down into monomers, which are very toxic. The process intensifies when the linoleum heats up (from a radiator, for example). Side effects- headaches, allergies, breathing problems.

Sand-lime brick is harmful to health

Did you know that all this applies to household air pollutants, i.e. releases impurities harmful to human health. As a result, we experience a decrease in immune defense and an increase in the number of viral and bacterial infections, as well as chronic respiratory diseases.

Which concrete is not harmful?

There is a company called Calera , which processes harmful gas emissions by distillation through sea water and other substances. This gas then transforms into magnesium or calcium carbonate and is drawn out of the water. These minerals are then used as fill material. Up to 90 percent of such materials are extracted from gas and then used to produce building materials.

Is concrete harmful to human health?

Most often, the harm of finely dispersed components that can get into the air and cause difficulty breathing is discussed. Doctors deny this possibility, but people still believe that if they have certain lung diseases, they will have to face new problems. Previously, asbestos and gypsum were used in finishing, which after drying could get into the air, but now this component is not used in the production of concrete.

Cement plant is harmful to health

Their concentration directly depends on the composition of the raw material, but it is very difficult to dispose of these hazardous substances. Once in the air inhaled by a person, up to 80% of them accumulate in our body with subsequent negative consequences. Cement factory Bonolith causes harm to humans due to the emitted dust.

Concrete is harmful to health

Why is cement dust harmful to health?

With prolonged contact with cement dust, the eyes suffer, up to conjunctivitis, dry skin appears, which entails the occurrence of dermatitis and affects Negative influence on the lungs, causing diseases such as chronic bronchitis or bronchial asthma.

Building materials harmful to health: TOP 10

7. Plastic panels. In fact, plastic is harmful in almost all forms, but plastic panels cause the most harm to health if they are used in a room where high temperatures reign: for example, a kitchen. Heat contributes to the release of toxic dioxin, the same applies to low-quality plastic windows, so the best option for finishing with plastic is a corridor or hallway, but not a living room or kitchen.

Health is expensive

Scientists and hygienists have long come to the conclusion that many diseases are determined by the quality of living conditions. Such illnesses have even received the name “housing diseases.” Currently, the safety of the built environment - the place where many people spend most of their lives - is becoming increasingly important. For about 20 years now, there has been such a thing in the world as sick building syndrome. The cause of this disease is the unsatisfactory effect of the indoor environment on human health.

How building materials affect health

Today I want to talk about harm of many building materials for human health. This article will provide information about toxic substances that are often found in certain building materials. The diseases they cause will be discussed.

Purchasing materials for construction and repair is a complex and responsible matter. When purchasing, most Russians first of all pay attention to appearance, manufacturability and cost of materials, and not on their safety. This approach is fraught with the most unpleasant consequences. Some modern building materials can have a negative effect on the human body, and many sellers, concerned exclusively with increasing income, prefer not to inform buyers full information about all the qualities of the goods sold.

We will try to fill this gap and introduce readers to the list of building materials that are unsafe for health.

Slate

In the recent past, slate was one of the most inexpensive and widespread roofing materials. The harm that it can cause to human health is primarily due to the fact that slate sheets are made from compressed asbestos fibers, which eventually disintegrate into tiny pieces. These particles are so small and light that they are in the air in the form of a thin suspension and, when inhaled, can enter the respiratory tract and settle there. The rate of asbestos destruction increases when heated. This means that a roof made of slate sheets literally poisons the residents of the house on hot summer days.

Asbestos is one of the most powerful carcinogens. Long-term inhalation of its particles is fraught with the development of not only inflammatory processes in the respiratory system, but also malignant tumors.

If you decide to use slate in your home construction, try to ensure that it is not exposed to high temperatures and weather changes. The easiest way is to paint the surface of the sheets, which will to some extent reduce the likelihood harmful effects health material.

Concrete

Concrete is used as the main material for pouring foundations, constructing load-bearing walls and strong partitions. It is used to make individual building elements (blocks and slabs), as well as massive structures. The material is technologically advanced, durable and inexpensive. Unfortunately, it is practically impenetrable to air, and living in a house built from concrete elements is quite harmful. In addition, slabs and blocks strengthen metal frames, which act as a kind of trap electromagnetic waves. It has been established that residents of houses built from reinforced concrete often suffer from increased fatigue and have problems sleeping. Experts associate such ailments with exposure to electromagnetic radiation.

When constructing monolithic structures, the method of filling the compactor with a concrete mixture is used. The base used is fine crushed stone, which is obtained from durable rocks (for example, granite). Not very conscientious construction companies do not bother checking the safety of the sealant, in particular its radioactivity. As a result, residents often move into apartments whose walls create an increased radioactive background for many decades.

Drywall

Drywall is used for interior decoration residential premises: leveling walls and floors, creating complex shapes ceilings and various light partitions. But few people suspect that this material can pose a health hazard.

Only high-quality drywall, which contains purified gypsum, can be considered harmless. It does not degrade in air and does not have any negative impact on the respiratory tract. The problem is that unsophisticated buyers often buy cheaper technical plasterboard, not intended for finishing residential premises. Such savings are unacceptable: low-quality material is not only less durable, but also harmful to health.

Expanded polystyrene

Two modifications of expanded polystyrene are used in construction: pressed (foam) and extruded. Both are used as insulation materials. In addition, some types of finishing wall and ceiling panels are made from foam plastic.

Expanded polystyrene releases chemical compounds such as styrene, phenol and formaldehyde into the air. They not only irritate the mucous membrane of the respiratory tract, but also accumulate in the body, gradually poisoning it. Therefore, experts do not recommend using polystyrene foam for interior decoration of housing. A long stay in a room lined with foam plastic boards has a bad effect on the condition of the liver and cardiovascular system. There is evidence that the accumulation of polystyrene foam breakdown products in the body of a pregnant woman can lead to fetal malformations.

Mineral wool

IN modern construction mineral wool is widely used for insulation and sound insulation. The material may release phenol and formaldehyde, which are toxic to humans. The likelihood of harm to health is high, since mineral wool easily breaks down into microparticles that enter the body through the respiratory system.

To avoid harmful effects of the formation mineral wool should be used exclusively as insulation, which should be placed between layers of other building materials. It is not recommended to drill walls and partitions built using mineral wool.

Dry plaster mixtures

Dry mixtures for preparing plaster, putty pastes, adhesives and other finishing materials should not contain any components harmful to health. The danger of materials of this kind is due to the fact that they are very easy and profitable to counterfeit. According to some data, the share of counterfeit dry mixtures sold on the domestic market is about 60%. At test purchases powders sold in counterfeit “branded” packaging contain poorly purified chalk, chemicals toxic to humans, and even components with a distinct radioactive background.

PVC products

Their polyvinyl chloride (PVC) materials make suspended ceilings, wall panels (siding), pipes, the most various elements finishing of premises (plinths, moldings, installation fittings for electrical wiring, etc.). The so-called plastic windows, in the manufacture of which PVC is also used. Products produced by European companies that support high standards quality, practically safe. The trouble is that the domestic market is overflowing with their low-quality analogues and fakes. Such materials can release dioxin, a powerful carcinogen, and toxic phenol.
