Automobiles Drive Toxic Mercury Into Environment
By Cat Lazaroff
DETROIT, Michigan, January 22, 2001 (ENS) - Automobiles are one of the nation's largest sources of toxic mercury emissions, show two new studies released today by leading environmental organizations. Despite practical, inexpensive alternatives and industry commitments to phase out its use, mercury continues to be widely used in new automobiles, the groups charge.
The organizations called on U.S. automakers to immediately eliminate the use of mercury in autos.
One of the reports - "Toxics in Vehicles: Mercury," a collaboration of the Ecology Center in Ann Arbor, Michigan, Great Lakes United, and the University of Tennessee Center for Clean Products and Clean Technologies - documents how dangerous levels of mercury are released into the environment once cars leave the road and enter vehicle disposal and recycling processes.
Automobiles are likely the single largest source of mercury contaminated scrap, the groups found. The report finds that EAFs are not only the largest manufacturing source of mercury air emissions in the U.S., but the fourth largest overall - behind only coal fired power plants and municipal waste incinerators.
"Our report clearly documents how the unnecessary use of mercury in automobiles is the primary culprit in contaminating the scrap steel recycling and recovery system," said Charles Griffith, auto project director at the Ecology Center, a regional grassroots environmental group. "These new findings show that the auto industry is one of the nation's largest sources of mercury pollution."
According to the second report - "Toxic by Design," released by the nonprofit Environmental Defense - auto manufacturers have continued to use mercury in product design and purchasing decisions despite known concerns and available alternatives. The report also finds that mercury is released by the manufacturers of automotive switches.
"Our studies show automakers are still using mercury, despite practical, low cost alternatives," said Dean Menke, Environmental Defense engineer. "The auto industry needs to immediately eliminate mercury use to protect public health and the environment."
While U.S. manufacturers continue to use mercury switches, international automakers such as Toyota, Volvo and BMW have completely eliminated mercury switch applications since 1993.
The findings of both reports support an action plan developed by the national Clean Car Campaign for eliminating mercury hazards caused by automobiles. The action plan calls on U.S. automakers to immediately eliminate the use of mercury switches in new cars and trucks, label component parts and vehicles that contain mercury, and take responsibility for the removal and safe collection of mercury switches in the existing fleet of vehicles currently on the road.
These recommendations are supported by more than 50 environmental and public health groups.
"Just as we expect automakers to take responsibility - and even recall - vehicles that pose safety or environmental hazards while on the road, they also need to address the serious hazards once their products are sent to the scrap heap," said Alexandra McPherson, clean production coordinator at Great Lakes United, an international coalition dedicated to preserving and protecting the Great Lakes-St. Lawrence River ecosystem.
