Aqueous runny nose, Stinging in the nose and throat, burning eyes, fatigue, headache and malaise are typical symptoms that can indicate a cold. But anyone who lives in an apartment building or in a freshly renovated house, you should think of for these symptoms to toxins like formaldehyde and solvents.

The colorless Gas, formaldehyde is a popular basic material in the chemical industry. It is used in large quantities for synthetic resins in particle boards, wood-based panels and furniture, but also as a preservative in paints, varnishes, and Plastering.

irritants from building materials and furnishings

to avoid injury, damage to Health, recommends that the Federal office for health BAG, that the concentration of formaldehyde in living spaces shall not exceed 125 micro-grams per cubic meter of room air.

solvents come primarily from inks, coatings, adhesives and sealants. You can pollute the air in the room greatly. With appropriate measures in the case of the sources, and adequate ventilation of the indoor space the concentration can be kept low. “When you Build, Renovate and Set up you should put on low-emission designs and products. Sometimes you can eliminate emissions entirely – for example, if you are somewhat mechanically fastened instead of glued,” says Roger Waeber, head of living poisons within the Federal office for health (BAG).

low-emission products are in the trading on the basis of goodness of character is recognized. Who found out only after purchase that it is a new purchase, a piece of furniture that charged the air in the room, you can airing for a while on the balcony or in the basement.

In new and renovated apartments should be airing during the first days and weeks more often with threading, residual solvent loads to get rid of. In the case of high formaldehyde loads, nothing else is usually left to remove the source.

Unhealthy pollution caused by fine dust in the interior

“A strong basic exposure to pollutants in buildings is due to dirty outside air – for example, due to fine dust and nitrogen oxides, in particular in cities and on heavily traveled roads,” explains Waeber VIEWS.

By Air fine dust get rooms necessarily in the inside. To the necessary Ventilation should not do without anyway. But on further sources of particulate matter such as harmful tobacco smoke or the frequent Burning of incense in the home.

Generally speaking, the inhabitants have, according to Waeber a lot of influence on the reduction of pollutants in homes and apartments. “Hazardous particulate matter from tobacco smoke, incense, or russende candles we can eliminate quickly. Regular checks and proper Cheer of fireplaces and Stoves has reduced the pollutant burden in the residential areas also.

Clean but right

is another factor for possible low-pollutant air in a room, the regular and proper cleaning of the living. The residents themselves have in Hand. “Basically, you should end up in the household environment – and health-friendly products are used. In addition, Sprays are preferable to those with a propellant,” explains Waeber to do so.

you can Also use a regular dust cleaning is important. Because in the house dust of many chemical and biological pollutants to accumulate. “Ideally, it wipes furnishings regularly with a damp micro-fiber cloth.” Because when you Wipe and vacuum always dust is stirred up, should you ventilate then the apartment with threading.

biological pollutants mold

mold infestation in homes is common and can affect health. Therefore, the mold should be quickly removed as soon as possible. Mold only grows where there is damp it is. It is therefore important that the cause is clarified and resolved. Mold infestation can occur, for example due to the Penetration of water to cool the walls, the lack of fans in the bathroom or insufficient Ventilation. In case of doubt, one should call for the clarification of a professional.

radioactive noble gas Radon in indoor

uranium found everywhere in the subsurface. Due to the natural decay of uranium is Radon, which is hovering in the air and inhaled, is formed. Radon can be long-lived, the radioactive elements decay. This can go unnoticed tissue deposits in the lungs and lead to lung cancer.

Particularly in the basement or the ground floor can spread harmful radon gas through the smallest cracks and cavities unnoticed, if buildings were built on the most permeable surface. “With relatively simple structural measures, this Problem can be solved but also of existing buildings,” says Roger Waeber. Various cantons radon measurements offer a free-of-charge. The radon map of Switzerland which is made available on the Website of the BAG, to show where the probability of a high radon concentration in buildings is greatest.

beware of asbestos in old buildings

Still, health-endangering asbestos, for example, by the use of asbestos-containing tile adhesives are to be found especially in older homes. Until the 1970s, asbestos-containing construction products were used very often. As long as no manipulations take place, asbestos is hardly a Problem. But it can be problematic in the case of conversions of buildings, as well as bathroom and kitchen renovations. Harmful asbestos fibers can be working at tag is released and inhaled, and, under certain circumstances, even after decades of the most serious Health consequences.

Waeber from the BAG recommends, therefore, prior to renovations in older buildings, an analysis by a professional. Also, anyone who is thinking of buying an older house or apartment and to rebuild the Waeber recommends the purchase of a pollutant analysis by a professional. This protects not only the health, and unplanned costs and Hassles can be avoided if, during the conversion, asbestos is proved and legally prescribed measures made need to be. Roger Waeber: “it Is determined asbestos before buying, you can negotiate a lower purchase price. So was it worth the analysis in several respects.”
