Pesticides in rainwater: A two-year occurrence study in an unexplored environmental compartment in regions with different land use in the State of São Paulo - Brazil.

Brazil's extensive agricultural area makes it the world's leading soybeans and sugarcane producer. Therefore, the use of large amounts of pesticides directly impacts all environmental compartments, including rainwater. We analyzed 14 pesticides and 5 degradation products in rainwater from three cities in the State of São Paulo, southeastern Brazil, with distinct land uses.
