Mercury in the Home Resource Guide
Mercury, also known as quicksilver, is a chemical element found on the periodic table. It is one of only five elements that are liquid at room temperature. Mercury is a heavy, silvery, transition metal, often found in household, medical and industrial products. The ability to easily bond with other elements and its versatility make mercury incredibly useful.
Although mercury is useful, it also poses significant health threats to humans. Exposure to mercury affects the nervous system and can have fatal effects. When not disposed of properly, mercury is also an environmental hazard. Recycling mercury is an important step in protecting human and environmental health.
Only one-third of the mercury found in the environment is naturally occurring, therefore human pollution is the greatest cause. Mercury containing products used around the house or garage often go unnoticed and are rarely disposed of properly.
Mercury can be found in many places inside your vehicle. Switches for breaks, seat belts and in the lights found inside trunks and hoods, all can contain liquid mercury. These automotive switches containing mercury are often easily and cheaply replaced and should be done so immediately.

Mercury vapor is used in fluorescent light bulbs because it is an incredibly efficient and environmentally friendly choice for manufacturers and consumers alike (they use up to 50% less electricity). Efficiency aside, the mercury vapors contained in fluorescent bulbs and HID lighting are highly toxic and easily absorbed by human body if the fragile bulbs are broken. These bulbs need to be handled carefully and recycled.
