Monitorou-se a presenca do herbicida Glifosato e do seu metabolito, acido aminometilfosfonico (AMPA), em amostras de aguas coletadas em area orizicola, submetida a plantio direto. Niveis de Glifosato em concentracoes acima do limite maximo permitido (7,0 µg/L) pela Agencia de Protecao Ambiental dos Estados Unidos (Environmental Protection Agency) foram detectados. A presenca do metabolito AMPA, nas aguas dos canais de irrigacao, foi detectada ate 120 dias apos a aplicacao (DAA). Pode-se dizer que determinado nivel de seguranca sera alcancado nas aguas de lancamento da granja para o Arroio Bretanhas, 120 DAA da formulacao de Glifosato. Como nao foi observada desercao do Glifosato em GLEYSSOLO HAPLICO Ta Eutrofico pode-se inferir que a concentracao do mesmo permaneceu como residuo ligado. Assim, a dissipacao do herbicida nesse solo pode ser reflexo, entre outros fatores, da formacao de residuo ligado, determinando desta forma o seu destino e/ou comportamento no ambiente. ENVIRONMENTAL MONITORING OF GLYPHOSATE AND ITS METABOLITE (AMINOMETHYLPHOSPHONIC ACID) IN TILLAGE WATER OF IRRIGABLE RICE Abstract Monitor the presence of the herbicide glyphosate and its metabolite, aminomethylphosphonic acid (AMPA), in samples of water collected in orizicole area, subject to direct plantation, was the objective of this study. Levels of glyphosate above the maximum permitted concentration limit (7.0 µg/L) were detected by the United States Environmental Protection Agency (EPA). The presence of the metabolite AMPA in irrigation channel water was detected up to 120 days after application (DAA). It can be deduced that a certain level of safety will be reached 120 DAA from formulation of glyphosate, for water from the Arroio Bretanhas farm. Since the desertion of glyphosate in a Gleyssolo Haplico Ta Eutrophic was not observed, it can be judged that the concentration of it remained as bonded residue. Thus, the dissipation of this herbicide in this soil can be a reflex of, among other factors, the formation of bonded residue, determining, in this manner, its destiny and/or behavior in the environment.
