Abstract: (30459 Views) |
| Residues of complex organochlorine and organophosphate as well as various compounds of polychlorinated biphenyls (PCBs) are reported from sediments and two species of fish ( Liza abu and Cyprinus carpio) residing in Arvand Rood River (ARR) in the Persian Gulf area. One hundred fish specimens and triplicate sediment samples taken from 15 stations 2 Km apart in an area close to the Persian Gulf were analyzed following protocol of MOOPAM -1999. Results indicated presence of PCBs, organochlorine (Endosulfan alpha and Endosulfane beta and Lindane) and no residues of organophosphates (Diazinon and Chloropyrophosphate) in sediments and fish samples. Concentrations of pollutants were higher in sediments and fish caught from stations 1 to 3 and 10 to 12. Recorded concentrations were, however, within or below the standard limits designated by Department of Environment, Iran. Considering the persistence of PCBs and insecticides and increased industrial and agricultural development in the region, more regular monitoring and ecological management of agricultural run-offs and industrial discharges into the river system is suggested. |
