This study was designed to evaluate the association between sugar cane plantation burning and hospital visits in Araraquara in the state of São Paulo, Brazil. From June 1 to August 31, 1995, the daily number of visits of patients who needed inhalation therapy in one of the main hospitals of the city was recorded and used as health impairment estimation. Sedimentation of particle mass (the amount of particles deposited on four containers filled with water) was measured daily. The association between the weight of the sediment and the number of visits was evaluated by means of Poisson regression models controlled for seasonality, temperature, day of the week, and rain. We found a significant and dose-dependent relationship between the number of visits and the amount of sediment. The relative risk of visit associated with an increase of 10 mg in the sediment weight was 1.09 (1-1.19), and the relative risk of an inhalation IMPLICATIONS Biomass fuels are considered to be a cleaner alternative than petroleum-derived sources of energy. Because of its renewability, zero balance in terms of CO 2 production, and less toxic emission, ethanol received a great focus in the development of the energy matrix in São Paulo. This paper deals with the possible but not always considered side effects of producing ethanol with low technological resources--the harvesting process after burning the plantations. The results of this paper indicate that the environmental benefits of using ethanol as automotive fuel have to be balanced with the adverse effects promoted by harvesting, pointing out that better agricultural technology has to be adopted to avoid adverse health effects due to smoke in the producing regions.therapy was 1.20 (1.03-1.39) on the most polluted days (fourth quartile of sediment mass). These results indicate that sugar cane burning may cause deleterious health effects in the exposed population.

“…Brazil had recently launched the world's largest alternative fuel program, using non-fossil power sources, so that such research was highly relevant. Experiments were performed in intoxication chambers, and the main finding was alcohol's lower toxicity as compared to fossil fuels (Böhm et al, 1983;Massad et al, 1985Massad et al, , 1986. No transposition of these findings to São Paulo's human population was performed.…”

Environmental epidemiology applied to urban atmospheric pollution: a contribution from the Experimental Air Pollution Laboratory (LPAE)

Systematic investigation on the effects of human exposure to environmental pollution using scientific methodology only began in the 20th century as a consequence of several environmental accidents followed by an unexpected mortality increase above expected mortality and as a result of observational epidemiological and toxicological studies conducted on animals in developed countries. This article reports the experience of the Experimental Air Pollution Laboratory at the School of Medicine, University of São Paulo, concerning the respiratory system and pathophysiological mechanisms involved in responses to exposure to pollution using toxicological and experimental procedures, complemented by observational epidemiological studies conducted in the city of São Paulo. It also describes these epidemiological studies, pointing out that air pollution is harmful to public health, not only among susceptible groups but also in the general population, even when the concentration of pollutants is below the limits set by environmental legislation. The study provides valuable information to support the political and economic decision-making processes aimed at preserving the environment and enhancing quality of life.
