RESUMO
Background:
Indoor pollution can be an important risk factor for human health, considering that people spend more than 60 percent of their time in their houses.Aim:
To investigate indoor pollution in a zone of extreme poverty in Metropolitan Santiago. Material andmethods:
During 24h, carbon monoxide (CO), sulfur dioxide (SO2), respirable particulate matter (PM10), polycyclic aromatic hydrocarbons absorbed in PM5, temperature and humidity, were measured in the interior of 24 houses in La Pintana, Santiago.Results:
The higher pollutant concentrations were observed during hours when heating was used, in houses that used coal (mean PM10 250 µg/m3, CO 42 ppm, SO2 192 ppb) or firewood (mean PM10 489 µg/m3, CO 57 ppm, SO2 295 ppb). In all houses, polycyclic aromatic hydrocarbons were detected and they came from the interior of the house and not from external filtered air. Coal, firewood and cigarette smoke were important sources of carcinogenic and kerosene and gas were sources of non carcinogenic polycyclic aromatic hydrocarbons.Conclusions:
In the houses studied, the population was exposed to an accumulation of highly toxic pollutants, caused by a lack of ventilation. A high relative humidity also contributed to the growth of biological pollutants
