Protect Yourself From Mercury!

What is so bad about Mercury?
Mercury is a naturally occurring element. But it is highly toxic, resists breaking down in the environment, and accumulates in the food chain. Mercury can permanently affect fetal and child development and can damage the brain, kidneys, and lungs.

What are major sources of mercury pollution?
Mercury is released through coal-burning energy production, some industrial processes, abandoned mines, garbage incineration, improper disposal, and accidental spills. Rain carries it from the air to watersheds where it can accumulate in the food chain, affecting certain types of fish.

How does mercury get into my body?
People are most commonly exposed to mercury by eating mercury contaminated fish. People who may become or are pregnant, and children are most susceptible to mercury poisoning. Susceptible people should be cautious of eating more than one fish meal from any source in a week. Certain kinds of large ocean fish should not be eaten at all, as well as some freshwater fish. See advisories and consumption guidelines for fish harvested in Oregon waters in the RESOURCES section.

Other routes of exposure are from breakage of mercury-containing devices such as mercury thermometers or fluorescent tubes.
