Abstract text

Trend data are valuable to assess the stability of contaminants in ecosystems and provide a first warning when potentially harmful contaminants may be elevating. Trend data are also valuable to examine the impact of regulations and regulator policy to limit the input of environmental contaminants to the environment. We studied temporal trends of contaminants in humans of the Arctic based on data published by AMAP. The aim is to provide a firm basis for future levels of pollutants in humans of the Arctic under climate and environmental changes. Several time series of 31 contaminants in humans of the Arctic from different cohorts were reported. The lengths of time-series and periods covered differ from each other. International restrictions have decreased the levels of most persistent organic pollutants in humans and food webs. Percentage changes for contaminants in human biological matrices (blood samples from children, mothers and males and breast milk samples) for the period of sampling showed declining trends in most of the monitored Arctic locations, with the exception of oxychlordane, hexachlorobenzene (HCB), 2,2',4,4',5,5'-Hexabromodiphenyl ether (PBDE153) and perfluorinated compounds (PFCs).
