Temporal variation of PCB concentrations in mussel tissue in two areas of Santander Bay (Spain)
An analysis was made of the temporal variation of polychlorinated biphenyls (PCBs) in wild mussel, Mytilus galloprovincialis, from two areas of Santander Bay (northern Spain) during 1991–2003, as well as of the posible influence of different external contributions on their concentrations. The concen...

| الملخص: | An analysis was made of the temporal variation of polychlorinated biphenyls (PCBs) in wild mussel, Mytilus galloprovincialis, from two areas of Santander Bay (northern Spain) during 1991–2003, as well as of the posible influence of different external contributions on their concentrations. The concentrations of the sum of seven PCBs (IUPAC numbers 28, 52, 101, 118, 138, 153 and 180) from the Pantalán area ranged from 21 to 38 µg kg–1 wet weight, whereas those from the Pedreña area, subject to less anthropogenic influence, ranged from 8 to 15 µg kg–1 wet weight. To determine the temporal evolution, the Kendall Tau-b correlation coefficient was used and a decreasing trend in PCB levels was verified for both areas. |
