Leicester/Nottingham Trent - Arsenic and old toenails

March 5, 2009

Scientists from the universities of Leicester and Nottingham Trent have devised a method of identifying levels of exposure to environmental arsenic - by testing toenail clippings.

Arsenic occurs naturally in the environment and people can be exposed to it in several ways. Long-term exposure to the substance is associated with increases in lung, liver, bladder and kidney cancers. The results have been published in the Journal of Environmental Monitoring.
