Abstract
Residues of organochlorines and organophosphates were determined by gas chromatography in water and sediment from 26 locations in 17 major rivers, 7 natural springs and 13 wells across Jamaica. Samples were collected on only one occasion between May and July, 1994. Residues of endosulfan were detected in all but three rivers; alpha -endosulfan in 15 samples of sediment (0.9-108.1, mean = 28.93, S.E. = 7.198 mu g kg super(-1)) and 13 of water (0.01-0.35, mean = 0.11, S.E. = 0.035 mu g L super(-1)), beta -endosulfan in 5 sediment (15.29-49.35, mean = 30.56, S.E. = 7.132 mu g kg super(-1)) and 12 water (0.05-0.31, mean = 0.14, S.E. = 0.031 mu g L super(-1)) samples, and endosulfan sulphate in waters of three rivers (0.003-0.244 mu g L super(-1)). Chlorpyrifos was present in 9 sediment (0.423-135.2, mean = 18.38, S.E. = 10.699 mu g kg super(-1)) and two water (0.001-0.022 mu g L super(-1)) samples, diazinon and ethoprophos in the sediment of one river each. Mean levels ( mu g L super(-1)) of alpha and beta isomers and sulphate of endosulfan were 0.16 (S.E. = 0.057), 0.12 (S.E. = 0.036) and 0.15 (S.E. = 0.089), respectively, in four of the seven springs and 0.23 (S.E. = 0.052), 0.11 (S.E. = 0.029) and 0.26 (S.E. = 0.088), respectively, in seven of the thirteen wells monitored.....
