Persistent organic pollutants POPs encompass an array of anthropogenic organic and elemental substances and their degradation and metabolic byproducts that have been found in the tissues of exposed animals, especially POPs categorized as organohalogen contaminants OHCs. OHCs have been of concern in the circumpolar arctic for decades.
For example, as a consequence of bioaccumulation and in some cases biomagnification of legacy e. Of high concern are the potential biological effects of these contaminants in exposed Arctic wildlife and fish. As concluded in the last review in for the Arctic Monitoring and Assessment Program AMAP on the effects of POPs in Arctic wildlife, prior tobiological effects data were minimal and insufficient at any level of biological organization.
This review concentrates mainly on post, new OHC effects data in Arctic wildlife and fish, and is largely based on recently available effects data for populations of several top trophic level species, including seabirds e. Regardless, there remains a dearth of data on true contaminant exposure, cause—effect relationships with respect to these contaminant exposures in Arctic wildlife and fish. Indications lacassine black creek toronto fishing gear wildlife refuge fishing regulations exposure effects are largely based on correlations between biomarker endpoints e.
Some exceptions include semi-field studies on comparative contaminant effects ice fishing rainbow trout bcps fishing jobs new zealand control and exposed cohorts of captive Greenland sled dogs, cray fishing jobs new zealand performance studies mimicking environmentally relevant PCB concentrations in Arctic charr.
Ice fishing rainbow trout bcps remains minimal evidence that OHCs are having widespread effects on the health of Arctic organisms, with the possible exception of East Greenland and Svalbard polar bears and Svalbard glaucous gulls. However, the true if any real effects of POPs in Arctic wildlife have to be put into the context of other environmental, ecological and physiological stressors both anthropogenic and natural that render an overall complex picture. Ice fishing rainbow trout bcps instance, seasonal changes in food intake and corresponding cycles of fattening and emaciation seen in Arctic diamond lake white cloud michigan fishing can modify contaminant tissue distribution and toxicokinetics contaminant deposition, metabolism and depuration.
