Temporal variation of PCB concentrations in mussel tissue in two areas of Santander Bay (Spain)

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...

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. Se presenta la variación temporal de bifenilos policlorados (PCBs) en mejillón silvestre Mytilus galloprovincialis de dos zonas de la Bahía de Santander (norte de España) de 1991 a 2003, así como la posible influencia en sus concentraciones de los diferentes aportes externos a que están sometidas ambas zonas. Las concentraciones de SCB7 (suma de los CBs Nos. IUPAC: 28, 52, 101, 118, 138, 153 y 180) de la zona de Pantalán, oscilan entre los 21 µg kg–1 en peso húmedo (ph) y los 38 µg kg–1 ph Mientras que en la zona de Pedreña, con menor influencia antropogénica, varían entre un mínimo de 8 µg kg–1 ph y un máximo de 15 µg kg–1 ph. Para conocer la evolución temporal, se usa el coeficiente de correlación Tau-b de Kendall y se comprueba la existencia de una tendencia decreciente significativa en los niveles de PCBs en ambas zonas. 2006-08-21 2021-06-03T03:55:13Z 2021-06-03T03:55:13Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1080 10.7773/cm.v32i22.1080 https://hdl.handle.net/20.500.12930/7407 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1080/1927 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 2B (2006); 465-469 Ciencias Marinas; Vol. 32 Núm. 2B (2006); 465-469 2395-9053 0185-3880
