PESTICIDE CONTAMINATION OF JAMAICAN ENVIRONMENT. II. INSECTICIDE RESIDUES IN THE RIVERS ANJD SHRIMPS OF RIO COBER BASIN, 1982-1996

摘要

Only organochlorine (OC) residues were monitored by gas chromatography in water, sediment and shrimp samples collected every month between July 1982 and August 1983 from the rivers of Rio Cobre basin. In samples collected every four months during 1989-1990, and seven times during July 1995-March 1996, OC and OP (organophosphates) residues were monitored. Cawrbamate and pyrethroid residues were not monitored. The detection of residues in 1982-1983 was 54 to 100/100 in water and sediment, and 83 to 100/100 in shrimp samples form various sampling stations in the four rivers. .
