“’Globally emitted contaminants accumulate in the Arctic and are stored in the frozen environments of the cryosphere, essentially meaning they have become reservoirs of toxic chemicals…
…the microbial potential to degrade anthropogenic contaminants, including polychlorinated biphenyls (PCB), polycyclic aromatic hydrocarbons (PAHs), and the heavy metals mercury and lead, was found to be widespread, and not limited to regions close to human activities.'”….Read More
