[Health threats for children in the modern building trade].

Changes in building industry during last 30 years in search of economic technologies and building materials ended in creating airtight and energy-saving constructions with reduced ventilation. As a result, diminish exchange between internal and external air, leads to cumulation of various chemicals and organic substances in our houses. Concentrated oxidation products (CO2, CO, NO2, nicotine smoke), vaporizing substances (formaldehyde, NH3, aromatic hydrocarbons) might irritate mucouses, promote or intense respiratory tract infections, allergic diseases or bronchial asthma. Higher risk of atopic diseases and bronchial asthma also arises from proliferation of fungus, bacteria and mites in modern interiors, which are quite convenient for it. Buildings with microclimate, which is dangerous for human health, are termed "sick buildings". Diseases that develop under their influence are called BRI (building related illnesses). Children are most exposed on them, especially under municipal conditions, because they spend majority of their time at home.
