摘要: The concentrations of 15 organochlorine chemicals (PCBs and pesticides) were studied in a Central European oak wood food chain system: Great tit (Parus major), caterpillars (Tortrix viridana, Operophtera brumata, Erannis defoliaria), oak-leaves (Quercus robur). Juvenile tits receive organochlorines from the mother via egg transfer and, eventually to greater extent, caterpillar source during nestling period. PCB 153 (2,2′,4,4′,5,5′-hexachlorobiphenyl, most abundant this study) was found leaf material at ca. 1 ng/g, 10 bird eggs 170 ng/g on an average dry mass basis.
