Researchers To Examine Effects of MMT: Manganese: Essential Element, Yet Harmful in Gasoline?

The potential health effects of manganese particles released into ambient air from vehicles burning gasoline with the controversial octane-boosting additive MMT (manganese methylcyclopentadienyl) will be examined by a series of experiments to be conducted at the Chemical Industry Institute of Toxicology (CIIT) in Research Triangle Park, N.C. The testing is slated to begin next year and to run for at least four years. Photo courtesy of Ford Motor Co. WEAR AND TEAR: The two spark plugs show co

The potential health effects of manganese particles released into ambient air from vehicles burning gasoline with the controversial octane-boosting additive MMT (manganese methylcyclopentadienyl) will be examined by a series of experiments to be conducted at the Chemical Industry Institute of Toxicology (CIIT) in Research Triangle Park, N.C. The testing is slated to begin next year and to run for at least four years.

WEAR AND TEAR: The two spark plugs show coloration differences between spark plugs from one car using MMT-containing gasoline (left) in Canada and another car not using MMT-containing gasoline in the United States, according to the Ford Motor Co. Inhalation experiments using monkeys and rats will examine the absorption, distribution, and elimination of what goes out the tailpipe when gasoline containing MMT is used in motor vehicles. The U.S. Environmental Protection Agency (EPA) and Ethyl Corp. of Richmond, Va., have been ...
