Abstrakt: Levels of organochlorine pesticides (OCPs), including ΣDDTs, γ-HCH, HCB, aldrin, isodrin, trans-nonachlor, heptachlor and dieldrin, were determined in the razor clam, Ensis siliqua, collected monthly from February 2003 to April 2004 from the Islas Cíes in Ría de Vigo (Galicia, Spain). The sum of DDTs ranged from 2.17 to 26.9 ng g dry weight (dw). Principal component analysis showed seasonal trends in the levels of some OCPs (γ-HCH and dieldrin). Pearson correlations ( p < 0.05) were observed between OCP levels and the biometric parameters of condition index and body lipids. [ABSTRACT FROM AUTHOR]
