The Human Health Effect Programme in Greenland, a review.

The burden of persistent organic pollutants (POPs) in Arctic peoples has been monitored for some years. In 1997, the Alta Declaration extended the mandate of the Arctic Assessment and Monitoring Programme (AMAP) to cover assessment of the combined effects of environmental stressors. The AMAP Phase I assessment report (Assessment report: Arctic pollution issues. Arctic monitoring and assessment programme (AMAP), Oslo Norway, xii+859 pp. Vol xii + 859 pp. Oslo, Norway, 1998) gave an overview of the classical toxicology of contaminants. Only recently a programme for measuring the potential biological effects of these contaminants has been established: The AMAP Human Health Effect Monitoring Programme. Body burden data alone are not enough to assess the health risks associated with exposure to environmental contaminants in Arctic peoples. Furthermore, laboratory studies of the effects of single chemicals or chemical mixtures in laboratory animals and cell cultures cannot fully elucidate the human health risks. Integration of epidemiological health research and effect-biomarker studies on humans from exposed populations in the Arctic is needed in order to obtain information about the real health risks resulting from exposure to the accumulated mixtures of contaminants in the Arctic. The present text aims to give a short account of background literature on known and suspected effects of environmental chemicals on endocrine regulated processes with special emphasis on Arctic conditions. Following the evaluation of existing knowledge, a survey of the recently started Human Health Effect Biomarker Programme in Greenland is given.
