Polar bear penis bones are being negatively affected by PCB’s that were banned back in 1979… but still float around in their environment.
PCBs, or polychlorinated biphenyls, were once used in everything from transformers to paint and are notorious for their ability to hitch a ride. They have been found all over the world, and they tend to hide out in whatever unlucky creatures eat them, ensconcing themselves in body fat and causing cancer and variety of other nasty effects.
Those effects, it appears, may also include damaging the baculum, a bone in the bear’s penis, scientists report in the February issue of Environmental Research.
