Population surveys in Greenland 1993-2009:Temporal trend of PCBs and pesticides in the general Inuit population by age and urbanisation
The purpose of the study was to analyse temporal trends (1993-2009) of the concentrations of organochlorine contaminants (14 congeners of polychlorinated biphenyls (PCB) and 11 pesticides) in the blood of Greenland Inuit according to age and urbanisation. Statistical determinants for the contaminant...
