Big Problem With Fish From Alaska

DDT in Alaskan fish shown to increase risk of cancer

Sally Robertson, B.Sc. – Researchers have found that children in Alaska who consume a lot of fish from rivers fed by the Eastern Alaska Mountain Range may be at an increased risk of cancer.

The study, which was conducted by Kimberley Miner (University of Maine Climate Change Institute) and colleagues, says the elevated cancer risk is due to the accumulation of insecticides such as DDT in the meltwater.

Compared with adults, the risk is significantly higher among children due to their size and life-time exposure. Imported Catfish? Throw It Back

The widespread distribution of OCPs throughout the Arctic has already been documented.

Some of the OCPS have been drawn in and transported in glacial ice, which, on melting, releases the pollutants into downstream reservoirs.

As Alaskan glaciers continue to melt as a result of climate change, the concentration of these OCPs released into the water may continue to rise far above the current level, says Miner.

“This secondary impact of climate change will be felt most strongly by children, and needs to be addressed in a comprehensive way,” she warns. More Problems With Imported Fish
