Mercury is a naturally occurring element that is toxic to people and wildlife. When products containing mercury are broken or thrown in the trash, outdoors, or down the drain, mercury cycles through the environment, polluting air and water, and accumulating in fish. You and your family can be exposed to mercury by breathing its fumes, eating contaminated fish, or touching spilled mercury.

The Massachusetts Department of Environmental Protection (MassDEP) has developed this page to provide you with a one-stop resource for learning about mercury, understanding its environmental and public health impacts, safely managing products and wastes that contain it, and finding out what state government is doing to reduce and ultimately eliminate the mercury threat.
