Resumo: The main goal of this work is to assess the pesticides impact on bodies of Almonda Subbasin in the agricultural area represents the most important In order to assess the waters collected in Almonda SubBasin herbicides were detected from the monitored pesticides, particularly 3,4 metolachlor, atrazine, terbuthylazine, chlorpyrifos, E and Z and propanil, reaching the maximum values, respectively of, 0.30, 0.05, 0.26, 0.16 and 7.41 Ecotoxicological tests were performed with the Pseudokirchneriella subcapitata, Chironomus riparius. Results revealed crustacean D. magna, specifically, samples and effects (immobitly/mortality) on the crust These results confirm reduced in the agricultural area at study. of Golegã.
