RESUMO
Pesticide formulations have been used in agriculture worldwide to protect the crops and soils from the attack of any pest. These formulations must be stored in safe containers proper to each kind of product. After use, the empty containers contaminated with pesticide residues must be disposed correctly and safely by triple rinse, the technical legislation recommended in Brazil. The aim of this study is to evaluate the efficiency of the triple rinse in empty pesticide containers that had been sent to the Collection site in Piracicaba region, São Paulo, through the analysis of the four main active ingredients traded in this region: gliphosate, MSMA, amethrin and tebuthiuron. In total, 75 gliphosate containers, 72 MSMA containers, 70 amethrin containers and 104 tebuthiuron containers were examined. The results were 34,67 % of the tebuthiuron containers, 58,33% of the MSMA containers, 75,71 % of the amethrin containers and 73,07 % of the tebuthiuron containers examined presented non-conformity with the actual technical legislation, that is, with residues above 0,01 %. This study concluded that the containers examined presented a high per cent of residue and that the triple rinse has not been executed according to the recommended technical legislation
