Mercury Information

Mercury is a heavy metal that can accumulate in living tissue. Exposure to mercury, when released into the environment through spills or incineration, can be toxic to humans and wildlife, or cause other health effects such as neurological and reproductive disorders. Therefore, proper management of used mercury-containing items and elemental mercury is important to protect human health and the environment. By keeping mercury-containing items and elemental mercury out of the trash, or preventing them from going down the drain, we reduce the potential for exposure to mercury. When products containing mercury are discarded in the trash, they simply do not disappear. Most of our trash is incinerated at a resources recovery facility. If a mercury-containing device is incinerated at such a facility, the mercury may enter the environment through the smoke stacks or through the resulting ash. If a mercury-containing device should break while in the waste stream, the mercury may be released into the environment.

By reducing the amount of mercury we use, we can then recycle only what is necessary for useful products for which there is no effective alternative. Bringing elemental mercury and mercury-containing items such as thermometers, thermostats and fluorescent lights to a household hazardous waste collection is one way to properly dispose of mercury-containing items. Another way to reduce the amount of mercury in the environment is to bring the used mercury-containing item, such as fluorescent lamps, to a licensed recycling facility. Check the household hazardous waste and recycling information pages of the Connecticut DEEP website for information on household hazardous waste collection programs and recycling opportunities.
