Chemical Pollution causes Greenland's Polar Bears to suffer bone loss

To learn how our use of solvents and pesticides banned in many parts of the world is even affecting Greenland polar bears, read POPs in Polar Bears on the Environmental Perspectives website.In controlled studies of laboratory mammals, organochlorines including the pesticide DDT and the group of industrial chemicals known as polychlorinated biphenyls (PCBs) have caused changes in bone composition including reduced bone mineral density. Organochlorines have also been implicated in other bone diseases including periodontitis, a disorder of the gums and bones around the teeth.
