Climate change increases risk of mercury contamination

  • In their research, recently published in Geochemical Perspectives Letters, scientists examined mercury reallocation — the movement from previously frozen soils into the surrounding environments — north of the Arctic Circle in Abisko, Sweden.
  • Air, water and soil were analyzed for methylmercury and researchers found that the fens had much higher concentrations of methylmercury than the other landscapes.
  • If it is converted into methylmercury upon release or during transport it has more potential to enter the food chain — through fish, birds and wildlife — and the potency increases as it moves up the food chain, making it a possible public health concern.
