Pesticide residues in the aquatic environment of banana plantation areas in the North Atlantic Zone of Costa Rica
Abstract A study of pesticide residues in surface waters and sediments was undertaken in the Suerte River Basin, Costa Rica, that drains into the Tortuguero conservation area. Samples were collected in streams, packing plants, and the Suerte River. The most frequently measured compounds in surface w...
