CONTAMINATION OF AQUATIC ENVIRONMENTS BY "URBAN PESTICIDES”: THE CASE OF COCÓ AND CEARÁ RIVERS, FORTALEZA - CEARÁ, BRAZIL

Authorship SCIMAGO INSTITUTIONS RANKINGS

Pesticides are used mostly in rural areas for agriculture, but urban pest control, public health campaigns, and household and veterinary products can also be important sources of these contaminants. This aim of this study was to estimate household pesticide contamination in sediments of two urban estuaries due to pest control: Cocó and Ceará rivers located in the metropolitan area of Fortaleza, Ceará, Brazil. Cypermethrin and malathion were found in both rivers. Cypermethrin levels had the same magnitudes as other studied urban areas and were highest in the estuary, while malathion was similar in both fluvial and estuarine zones.
