Residues of organochlorine (OC) and organophosphorous compounds (OP) were monitored by gas chromatography monthly for over a year in plantation soil, and water, sediment and fauna of three rivers and coastal waters of Portland watershed. OP residues were not detected in any sample while OC residues were below detection levels in the Rio Grande. Dieldrin residues were detected only once in water (0.2 ± 0.03) and sediment (0.02 ± 0.003) of the Spanish River, the water (0.76 ± 0.09) of the Swift River and the sediment (0.1 ± 0.005) of the sea coast; pp´ DDE was found twice in the water (3.1± 1.53) and sediment (0.1 ± 0.007) of the Swift River and the water (0.8 ± 0.22) and the sediment (6.14 ± 0.41) of the sea coast. Arochlor was detected only twice (0.011 and 0.153) in the water of the Spanish River.....
