[Benzo(a)pyrene in atmospheric and indoor air, health hazards and possibilities of limitation]

Abstract

The work discusses the occurrence of benzo (a) pyrene in atmospheric air and indoor air, as well as health threats caused by this environmental pollution. The results of research conducted worldwide and in Poland were referred to. Poland belongs to the European Union country, where high levels of benzo(a)pyrene are recorded in both atmospheric air and indoor air (residential houses) exceeding 1ng/m3. Considering the fact that this pollution is highly carcinogenic one should strive to reduce the concentration of benzo(a)pyrene in the air in Poland, recognizing and eliminating its sources. Installation of dedusting equipment in residential areas is possible but expensive. This creates an inequality in the access to fresh air in the rooms. The World Health Organization strongly promotes measures to reduce emissions of benzo(a)pyrene. On the other hand, extensive information campaigns should be carried out to make the public aware of the exposure, its sources and options of prevention.
