Threats to human health caused by mercury almost always result from pollution generated by humans. In addressing these threats, both environmental organizations and the private sector recognize that there are cost-effective alternatives to the use of mercury that do not pose health threats. Reducing the use of mercury is thus the main thrust of efforts to control this toxic element. This article presents a survey of the challenge posed by mercury pollution, the main sources of that pollution, and the joint international efforts to take on this problem.
