[Comments on studies of industrial and non-industrial environments in Brazil: a comparative approach].

Air quality in industrial environments has been studied since the second half of the 20th century. Well-documented results show that exposure to chemical pollutants through their consumption, production, and storage can damage workers' health. New research focusing on non-industrial environments has shown unexpected correlations between air quality and health effects. Artificial ventilation systems have been related to health-related complaints and a high rate of absenteeism. Symptoms related to air quality in non-industrial environments are recognized by the World Health Organization and encompassed under the so-called sick building syndrome (SBS). In Brazil there are few studies comparing indoor air quality and health. The present study is intended to map the studies already conducted in Brazil in order to encourage further research in this area, due to its importance for public health.
