Over the last two years, Governor Blagojevich and the Illinois General Assembly have enacted a number of laws to reduce the health risks associated with the use and disposal of consumer, household and commercial products that contain mercury. These products include thermometers, switches, electrical relays and scientific instruments used in schools. The purpose of these laws is to reduce mercury releases into the environment. Mercury is a strong neurotoxin that can be harmful to the health of humans and wildlife. Mercury exposure poses a particular risk to young children and pregnant women because mercury may inhibit the development of the brain and nervous system. This report presents recommendations for improving efforts to reduce and recycle mercury components that are found in thermostats and motor vehicles. Illinois EPA prepared the report in response to Public Act 93-0964. In drafting the report, Illinois EPA conducted research on mercury reduction and recycling programs in other states, reviewed technical studies and consulted with officials in the private and public sectors.
