Previous issue date: 2009-03-27 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The objectives of this research were to investigate the agrotoxic most used in the Gramorezinho region in the green belt of Natal, and to evaluate the acute toxicity of
these, based on the LC50-48h values estimated in tests for Danio rerio, internationally used as test organism. The acute toxicity tests were performed under laboratory conditions, according to standardized methods (ABNT/NBR/15088/04) for this species. The LC50-48h estimated to Tamaron BR was
352.89 mg.L-1, which characterizes that as practically non-toxic, according to toxicological classes cited by Zucker. For Decis 25EC, the LC50-48h estimated was 0.0004156 mg.L-1 (4.156 X 10-4 mg.L-1), which classifies it as highly toxic to this species / Os objetivos deste trabalho foram investigar os agrot?xicos mais utilizados na Regi?o de Gramorezinho Cintur?o verde da Grande Natal' e avaliar a toxicidade aguda dos mesmos, com base nos valores da CL50-48h estimados em testes com o
peixe Danio rerio, organismo-teste eleito internacionalmente. Os testes de toxicidade aguda foram realizados em condi??es de laborat?rio, de acordo com a norma da Associa??o Brasileira de Normas T?cnicas (ABNT/NBR/15088/04) para
esta esp?cie. A CL50-48h estimada para o Tamaron BR foi 352,89 mg.L-1, classificando-o como praticamente n?o-t?xico, de acordo com as classes toxicol?gicas citadas por Zucker. Para o Decis 25EC, a CL50-48h estimada foi
0,0004156 mg.L-1 (4,156 X 10-4 mg.L-1) que a classifica como altamente t?xica para esta esp?cie
