    Abstract

    Thirty-seven addled peregrine falcon eggs collected in South Greenland between 1986 and 2003 wereanalysed for their content of the organochlorine compounds polychlorinated biphenyls (PCBs), dichlorodiphenyltricloroethane (DDT) and its degradation products, hexachlorocyclohexane (HCH) isomers andhexachlorobenzene (HCB). PCBs and DDT (including metabolites) were by far the most abundant OC groups,with median concentrations of 55 and 40 μg/g lw, respectively. The concentrations were high in an Arcticcontext, but similar to previously reported levels from Alaska and Norway and slightly lower thanconcentrations measured in eggs from industrialised regions. Geographical differences may be of importance,considering the migration of peregrine falcons and their prey. ΣHCH and HCB had median concentrations of0.39 and 0.17 μg/g lw, respectively. On average, DDE accounted for 97% of ΣDDT, but was below critical levelsfor eggshell thinning. All compound groups showed a weak decreasing trend over the study period, whichwas statistically significant for HCB and close to being significant for ΣHCH. The weak decrease of ΣPCB andΣDDT is different from other time trend studies from Greenland, usually showing a more pronounceddecrease in the beginning of the study period, followed by a certain stabilisation in recent years
