"Toenails are in individual plastic bags stored in filing cabinets - no special freezers or storage units required. When a toenail is able to be clipped it's on average about 10 to 14 months old. Some environmental contaminants and heavy metals - including arsenic - are preferentially deposited in toenails. They have an affinity for keratin so naturally attracted to it through human biology."
"The Atlantic Partnership for Tomorrow's Health (PATH) is part of the Canadian Partnership for Tomorrow Project, the largest study of its kind undertaken in Canada. It is investigating the various factors that contribute to the development of cancer and chronic diseases, including the longer-term health impacts of arsenic."
