INSECTICIDE CONTAMINATION OF JAMAICAN ENVIRONMENT. IV. TRANSPORT OF RESIDUES FROM COFFE PLANTATIONS IN THE BLUE MOUNTAINS TO COASTAL WATERS IN EASTERN JAMAICA

摘要

A survey of 120 coffee farmers in the Portland waershed revealed that they lacked training in pesticide application, and had no concept of the transport of residues in the environment and theri impact on non-target organisms. Residues of organochlorine (OC) and organophosphorous compounds (OP) were monitored monthly for over a year in plantation soil, and water, sediment and fauna of three rivers and coastal waters of Portland watershed by gas chromatography. OP residues were not detected in any sample while OC residues were below detection levels in Rio Grande.
