Abstract

Quantification of emerging contaminants is considered a key issue for assessing their behavior in aquatic systems and further to human exposure in order to study the possible health effects to the population. Objective: Assessment of pesticide residues and pathogenic protozoa - Giardia and Crypostoprodium - in public water supplies in the State of São Paulo, aiming to support the surveillance activities of water quality. Method: The water collection will be held monthly at the catchment and output point of Water Treatment Plant for a period of 1 year comprising 26 cities in the São Paulo state. The pesticide residues analyze will be carried out in the Laboratory of Embrapa Environment in Jaguariuna (SP), laboratory accredited by INMETRO according to NBR 17.025. Previously, 40 pesticides were selected according to existing cultures in each municipality and their physicochemical properties which favor their transportation to surface water. For quantification of Giardia and Crypostoprodium samples, will be collected monthly in 11 cities for a period of 1 year. The samples will be performed according to USEPA - Method 1623/2005 in the Biological Analysis Laboratory, School of Public Health in Sao Paulo. Expected results: Acquiring data regarding dozens of pesticides residues and emerging protozoa level in surface water sources. Consolidation of technical background to review and approval plans for sampling of pesticides and Cryptosporidium and Giardia in water sources in the state of São Paulo by the surveillance tasks.
