Common Causes Of Mercury Contamination

Contact With Older Paints

For many years, mercury was added to indoor, water-based latex paints as an effective way to control the growth of bacteria and prevent mildew. For this reason, contact with older paints can lead to mercury contamination. While in the United States this practice was banned in 1990, individuals may still have these paints sitting in their garages or basements. The greatest concern is after the initial application when the highest amount of mercury vapor is produced. If homeowners find old cans of this paint, it is important to dispose of them properly. They should not pour the paint out of cans and down a drain. Instead, they should bring the paint to a hazardous waste disposal center.
