RESUMO

Objective. The 1989 Brazilian\ s pesticide legislation (Law n° 7802/89) was considered an important improvement to control environmental and health problems. This study aimed to evaluate the impact of the law and it\ s regulations to the toxicological and environmental classifications of pesticides by hazard and to the notified poisonings. Methods. Pearson Correlation and Regression Analysis were used to evaluate the correlation between pesticide sales and notified intoxications in Brazil, from 1985 to 1999. Kappa Coefficient and Ridit Analysis (Relative Identified Distribution Analysis) were used to compare the WHO (World Health Organization) classification of pesticides by hazard of the group of chemicals that was registered in 1990 and the group registered in 2000. The toxicological and environmental classifications and the allowed destinations of the pesticides that were registered after the law were also analyzed. Results. The correlation among sales of pesticides and poisonings was positive (r=0,82 ; p<0,0001). The equation obtained make possible to estimate poisonings notifications using values of pesticides sales (R =0,95; F=253,48; p<0,0001): intox = 0,00236 x sales (US$ l,000.00) . No significant toxicological and environmental classifications differences were identified between the groups of pesticides that were registered in 1990 and 2000. The most economical expressive crops received the majority of the registers. More toxic pesticides were registered to destinations that had less toxic ones. Conclusions. After ten years of Law it was not possible to consolidate the expected improvements. Recommendations included: enforcement of the law, priority to less risky pesticides, restriction to more toxic ones
