摘要: Abstract Investigations concerning the polychlorinated biphenyl (PCB) levels conducted from 1984 to 1992, showed persistent pollution in surface sediment of Seine river (from 50 26000 μg/kg dry weight). A significant correlation between particulate organic carbon (POC) and PCB was found (P⩽0.05). In different depths (3, 10 25 cm), our results led same conclusion: increased according depth were related rise POC levels. Sediment patterns at Maisons Laffitte, Acheres Porcheville no microbial biodegradation even deepest under methanogenic conditions. The distribution components appeared depend mainly on their physical chemical properties.
