MOLINA ESQUIVEL, Enrique. Biological indoor air pollutants at home: contributing factors, related diseases and corrective actions. Rev Cubana Hig Epidemiol [online]. 2015, vol.53, n.1. ISSN 1561-3003.

Biological indoor air pollution in households and public places is an important cause of morbidity and discomfort. It may interact with chemical pollution, with which it often shares common sources. The main biological pollutants are moulds, exoskeletons and feces of dust acari, cockroaches and other insects, skin flakes, and hair from pets, all of which may act as allergens, bacteria such as Legionella, viruses and other infection disease agents. Contributing sources and factors include the dampness created by leaks in the plumbing, high relative humidity, poor natural ventilation or insolation, inadequate technical control of components of air conditioning equipment, deficient cleaning, and crowding. Prevention and correction measures include the reduction of humidity and elimination of its sources, optimization of natural ventilation and insolation, appropriate maintenance of mechanical ventilation systems ensuring an adequate rate of air renewal, cleaning of carpets with highly efficient particle removal devices, and frequent washing of the furniture and curtains (or removal of the latter if they obstruct natural ventilation).

Keywords : biological pollutants; allergens; bacteria; viruses.
