Mercury is a nerve toxin that has a major impact on the brain, particularly in growing fetus and juvenile. Mercury can also damage reproduction in mammals by interfering with sperm formation. Neurological and reproductive effects have also been seen in birds. In fish, its effects also include a decreased sense of smell, damage to gills, blindness and changes in the ability to absorb nutrients in the intestines.
WWF supports the United National Environmental Program (UNEP), which is currently conducting a global survey of mercury sources and pathways that it hopes will lead to a global convention on mercury.
