How dangerous is black mold in the house for the human body and how to get rid of it. Mold in the apartment: causes and how to get rid of it

Comments:

Mold appeared several billion years ago, however, serious research began only in the last century. Taking into account the estimates of mycologists, 50,000 species are currently unknown to science. But scientists learned about the dangers of mold for human health only in the last century.

Regular ventilation of the room will prevent the appearance of fungus.

So, what is fungus on the walls, how does it affect your health? Should we be afraid of him? What is the harm from mold? Usually, such questions interest a person only when mold appears in the house. Therefore, it won’t hurt anyone to find out in advance about how mold affects people’s health.

The influence of pathogens on human health

What is fungus on the walls? What harm does it cause to people? As a rule, these are simple microorganisms that are able to form colonies. They appear as black spots on walls, wallpaper, and products.

As you know, fungi can have a rather insidious effect on the health of everyone in the room. The products of their metabolism are an allergen for humans. During its development, mold on walls releases toxins (which are volatile, liquid) and spores that can be easily spread by air currents. Immediately after this, spores and toxins enter the respiratory tract of people.

Thus, pathogenic microorganisms cause irreparable harm to humans - they begin to affect the weakest areas of the body that are prone to chronic diseases.

The fungus very quickly undermines health. People buy all kinds of drugs, hoping for their help. However, such help is short-term and can only make you feel better for a certain time. Diseases begin to periodically worsen during the off-season - just at the moment when indoor air humidity increases. It is because of this that the concentration of fungal spores, which people constantly inhale, increases. Using this method, a person adds harmful bacteria to the body that have a bad effect on the beneficial microflora of the immune system. Because of this, people quickly age, attributing this to various reasons, but not paying attention to the uncomfortable living with dampness.

Harm from microorganisms: different effects on humans

The toxic effect can manifest itself in the form of mild weakness, increased fatigue, and irritability. As a rule, people think that this is ordinary fatigue from work. Over time, a person may develop cirrhosis of the liver - one of the main consequences.

If a person regularly consumes mold with food, he will live a very short and painful life. Among the consequences of toxic effects are cardiovascular diseases, sinusitis, migraines, nosebleeds, and cough.

If we talk about the allergenic effects of mold, it manifests itself in the form of allergies to the skin and mucous membranes. For example, allergic rhinitis is a fairly common disease. But hay fever, one of its most common types, is almost always caused by fungal spores. Bronchial asthma is also provoked by black mold.

Quite often, mold allergies are observed in children. Since everyone’s susceptibility to the fungus is different, the severity of the consequences of being in an infected place also differs.

As for the carcinogenic effect, it manifests itself at the moment when the fungus gets into the food. Remember, if mold does form, there is no point in cutting off the affected piece of bread - the entire product must be disposed of immediately.

Mold spores are almost invisible, which makes the process of eliminating mold much more difficult. Thanks to this property, microscopic fungi are able to penetrate small crevices and begin to actively reproduce.

Mold can be painted in various colors (pink, white and others); in apartments, the presence of black fungi is most often noted. The spores of this microorganism are found everywhere: in water, on the ground, other surfaces, even on the keyboard (if you forget to wipe it regularly with a damp cloth).

To successfully get rid of mold in an apartment, you need to know the causes of fungus in the house. Experts identify several probable causes of the appearance of fungal formations:

high humidity. The presence of high humidity is one of the main negative factors that affects the occurrence of mold. This is why fungus often settles on the ceiling, walls in the bathroom, kitchen;
insufficient ventilation. Poor performance of the ventilation system leads to the retention of pathogenic microorganisms in the room, their settling on various surfaces. Most often, this process is observed in the bathroom; many complain about the presence of black spots on the ceiling and walls of the room. Often such problems arise during installation plastic windows which violates natural ventilation in the apartment;
hypothermia of the walls, which is celebrated in winter. The situation occurs when mistakes are made during the construction of a house;
presence of cracks in the walls of the apartment. Unnecessary moisture enters the house through the openings, creating favorable conditions for the proliferation of mold spores. Trouble arises against the backdrop of unsuccessful repairs, negligent replacement wooden windows for plastic ones, non-compliance with technical recommendations;
poorly sealed interpanel seams, which opens the way for pathogenic microorganisms. A problem arises due to the use of low-quality sealant, if the right technology this process.

There are a lot of negative factors; it is important to find out the specific cause of mold in the apartment and eliminate it. Only then should you remove the existing fungus.

When contacting human skin, fungal spores provoke the development of skin rashes, eczema, and dermatoses, which are difficult to diagnose and even more problematic to treat. The human body weakens, the appearance of constant fatigue, the presence of migraines, headaches.

Mold spores are strong allergens; the negative reaction intensifies when they enter the lungs. A person runs the risk of developing a chronic runny nose, conjunctivitis, and often has an unreasonable cough. Spores can quickly penetrate the respiratory tract, irritating cells, leading to serious allergic diseases, including bronchial asthma.

Mold will release foul-smelling substances into the air, which often cause serious intoxication in the body of people, pets, and even suffer houseplants. The condition can worsen sharply; some doctors have noted cases of severe headaches, attacks of nausea, and vomiting.

Note! Prolonged proximity to fungi leads to pathologies of musculoskeletal tissue, cardiovascular system, and rheumatic pain. There are problems with normal digestion, there is a danger of damage to the liver and kidneys.

Destruction of favorable conditions

improve heating. Make sure that radiators and other heating devices heat the entire room, and not a separate object (move them away from the sofa, wall, place them so that warm air blew into space). It is important to ensure that the room is heated evenly; do not keep the bath closed; if this room is not heated, the likelihood of mold growing increases;
provide high-quality thermal insulation. Main problem areas: joints between walls and floors, ceilings, doorways, window perimeter. Cracks are formed as a result of non-compliance with construction technology and cosmetic work;
improve ventilation in the house. Walk around the apartment with a candle if the fire is not moving in the direction ventilation holes, then clean them and correct the problem immediately. Also check the neighboring apartments; it is likely that the problem lies in their ventilation;
Eliminate sources of water leakage. Seal the pipes and change the finishing material around this area. If this is not possible, then dry the surfaces with an industrial hair dryer and treat with an antiseptic;
fight capillary moisture. It oozes from neighbors or through finishing material from the street. Waterproofing walls, ceilings, and Special attention water pipes;
get rid of hydrophilic materials in rooms with high humidity. Such items can be products made from fabrics, wood, remove them from the bathroom, if possible from the kitchen, replace them with hydrophilic products from modern materials.

Fighting fungal colonies

Now start fighting the fungus directly in the apartment mechanically using a variety of means

Recipes:

antiseptic primer. It is easy to find in any hardware store, use Stop Mold, Alpa, Dali and others. Their use will help not only destroy existing fungal colonies, but also prevent the reappearance of uninvited “guests”. It is important to thoroughly clean the wall before processing; if necessary, remove all finishing material down to the brick;
bleaches found in every home, they do an excellent job not only with stains, they quickly kill mold, and are an excellent alternative to professional products. Do not use the preparations on all surfaces; some of them will then be impossible to restore. Bleach is allowed to be used on bathroom tiles, the bathtub itself, and glass surfaces. Disadvantage of this method: bleaches are not effective on drywall and wood. Wear gloves during the procedure, dilute bleach with water in a ratio of 1:10;
vinegar, hydrogen peroxide, ammonia. These remedies for mold on the walls in the apartment have destructive power; they are used together with water in equal proportions. Treat the desired surface with the resulting raster, do not wash off. To obtain the desired result, repeat the manipulations several times.

Why are mold and mildew dangerous?

Fungi in the bathroom or home are colonies of single-celled microorganisms. They reproduce by spores. These single-celled organisms were among the first living creatures to appear on planet Earth. They were able to adapt to numerous climate and environmental changes. Fungal waste products can be harmful to human health. This:

essential oils
minerals
toxins

IMPORTANT: The fungus appears as a black, brown, dirty green or dirty yellow color that appears on the walls and ceiling of the bathroom, water pipes, joints between furniture or plumbing and walls, the furniture itself. In the house he “lives” in damp and dark places. A specific smell can also indicate the presence of pathogens.

Spores, toxins and other harmful substances produced by mold spread throughout the home. They settle on the skin, mucous membranes, in the lungs and stomach, and enter the blood. As a result, a person may experience various health problems:

intoxication
predisposition to allergies
predisposition to cancer
decreased immunity
allergic bronchitis, bronchial asthma, other irreversible diseases of the bronchopulmonary system
liver and gastrointestinal diseases
headache

IMPORTANT: The fungus itself is also an allergen
In addition, mold and mildew eat deep into the surface and destroy it. This applies not only to wood and paintwork, but even to concrete and masonry.

What to do to prevent mold from forming?

Favorable factors for the formation of mold and bending are:

high humidity
poor ventilation
lack of sunlight

Pathogenic microorganisms are likely to inhabit a home or bathroom if:

The premises are not ventilated. Doors to the bathroom, toilet, pantries, and other rooms that have no windows, are dark and damp, must be kept open from time to time
After water procedures splashes and drips of water remain in the bathroom. They need to be wiped thoroughly
The plumbing is faulty. In the kitchen, bathroom, toilet, leaky pipe joints, cracks and fistulas, the moisture evaporating from them, settling on the surface, prepares favorable soil for the colonization of the fungus
Low quality materials are used. During renovations in the kitchen, bathroom, toilet, or balcony, it is necessary to use materials that are suitable for use in humid conditions, have antifungal properties or have been treated with an antifungal compound
Unclean neighbors live nearby. If the next room is damp, moisture seeps through risers and slab joints

VIDEO: How to remove fungus from an apartment?

The appearance of fungus in an apartment is extremely undesirable, not only for aesthetic reasons, but also because of the detrimental effect on the health of the owner of this house. It appears and takes root very well not only in apartments with old renovations. Since the fungus spreads very quickly, the slightest accumulation of dampness and high humidity can cause it to appear even on new tiles in the bathroom or other places. To prevent this from happening, you need to act decisively at the first symptoms of its occurrence, since old mold is much more difficult to remove than fresh mold.

Harm from mold

The appearance of mold in an apartment or house can cause a variety of diseases in its residents: for example, allergies, cough, runny nose, feeling of lack of air and other problems with the immune system. Detecting and removing mold is absolutely necessary for the safety of your home and the ability to live in it.

Sometimes a person is cured of complex, difficult to diagnose, chronic diseases simply after moving to another apartment, dry, without mold contamination.

And of course, the aesthetic side of the matter: no apartment is decorated with stains and dirty deposits in the corners.

Causes

To completely and irrevocably get rid of the fungus, you first need to determine the reasons for its appearance. More often it appears due to high humidity and lack of ventilation. Fungi love just such rooms. IN damp houses, apartments located on the ground floor, in a room where the humidifier was not used correctly, in the case of maintaining a tropical climate for special plants growing in large quantities in small rooms - this is where mold will feel comfortable.

Almost all modern construction and Decoration Materials are affected by the fungus. It can be found in the bathroom, toilet, and air conditioner. Even washing machine, refrigerator, books, wallpaper or just walls can be infected with mold. It is sometimes very difficult to get rid of it.

Among the signs of mold in the house, one should note the appearance of a specific smell, damp and pungent. The next stage will be the appearance of spots - gray, black or whitish.

If not eliminated high humidity and in the future do not ventilate the room, all the measures you have taken will be useless, since the fungus will appear again.

In what areas should you start working:

mechanical cleaning of walls, floors, ceilings from fungus;
treating all surfaces with a product that will destroy mold;
getting rid of all things damaged by fungus and as a result unsuitable for further use;
equipment for constant good ventilation of the room, preventing stagnation of air masses;
reducing room humidity. Detection and elimination of all sources of high humidity.

By what means can I remove the “uninvited guest”?

To eliminate this problem, special antiseptic agents are produced. Any store that sells will offer you a large selection building materials. Always remember that everything chemicals to combat fungus, they are very poisonous and any work with them must be done with great care, having first read the attached instructions.

In the struggle for a clean home, you must also consider the fact that defeat upholstered furniture, wallpaper, porous materials can be very deep and cannot be cleaned. In such cases, it is better to get rid of them.

Most The best way eliminating fungus - treatment with a special antiseptic primer, sold in any hardware store. This product is easy to use; as a rule, you do not need to add water to it. When purchasing it undiluted, read the instructions to obtain the required composition.

The surface must be cleaned before applying the product. If the fungus penetrates deeply into the plaster, it is necessary to remove it to a clean surface, maybe even to concrete slab or brickwork. The primer is spread over a dry surface using paint brush. After it dries, the surfaces are painted or wallpapered.

Fungus can also be combated using home remedies. They have a slightly lesser effect, but are not so toxic. Regular bleach can remove all types of fungi. The sodium hypochlorite in its composition kills both the fungus itself and its spores. Bleach perfectly cleans bathroom tiles, glass, and floors, but its effect is such that some of the treated items may lose color.

If this product is used incorrectly, you can damage the skin on your hands. Be sure to use rubber gloves. Before starting work, it is also necessary to ensure that the room is ventilated to protect it from harsh and toxic fumes. To treat surfaces, prepare a mixture of bleach and water in a ratio of 1 to 10.

Many common types of fungus can be combated with regular table vinegar, which is essentially a weak acid. This product also does not smell very nice, but its fumes are not as toxic as bleach. To get rid of fungus, vinegar is applied to the affected surface with a spray bottle or using a dampened rag. After an hour, the treated surface is washed with water, and the room is ventilated.

To prevent the fungus from appearing again in the future, it is enough to spray vinegar in the problem area once a week.

You can also use hydrogen peroxide - it is also an antibacterial and antifungal agent. You can go to any pharmacy for a three percent peroxide solution. The solution is non-toxic and does not have a pungent odor.

Peroxide has been proven to be effective, but it also bleaches many materials, so care must be taken when working with fabrics and painted surfaces.

The use of this product is quite effective when working with hard, non-porous surfaces - tiles or glass, on porous materials it is ineffective. To work, ammonia and water are mixed in equal proportions, the resulting mixture is sprayed over the infected area, and washed off after a few hours.

Be careful, as ammonia, when it evaporates, causes headaches and discomfort in the throat, and when mixing bleach and ammonia, a toxic gas is generally released.

Baking soda is a natural and safe household cleaner. It does not contain such aggressive chemicals as other products, so its use is not dangerous to either people or animals. Take one teaspoon of soda per glass of water and treat moldy surfaces with the resulting solution. You can spray or simply soak a sponge in the solution and clean the infected area with it. In this case, it is better if the remaining soda is not completely washed away - this will prevent the fungus from returning.

It is not difficult to remove fungal plaque using a variety of means, but this is only part of the job. A prerequisite for success is to ensure dryness and regular ventilation of the home.

Step-by-step instructions for getting rid of mold

We remove and eliminate sources of moisture. It is necessary to check the condition of the tile joints on the outside of the house, leaking taps, cracks in the walls or under the windows through which moisture seeps in, breeding pathogenic spores. We check the ventilation draft and troubleshoot problems.
After eliminating the causes of mold, we begin its removal. Use a wide metal spatula to clean the affected plaster.
We dry the walls with heating devices or blowtorch. Do not forget about safety precautions and extreme caution. We purchase an antifungal agent.
We apply high-quality antiseptic with a brush or spray gun. After five to six hours, the surface is cleaned a second time, washed and dried. Antiseptic treatment is carried out again. The treated walls will be ready for pasting or painting within a day.
