Monitoring reformulated gasoline in milwaukee, wisconsin

摘要

Beginning in January 1995, the 1990 Clean Air Act Amendments required the introduction of reformulated gasolines (RFG) in six counties in southeastern wisconsin. The reformulated gasoline was to contain an increased percentage of chemical oxygen (oxygenates); reduce toxic components; and to provide lower evaportative emissions. With introduction of the oxygenated gasoline blends, the Wisconsin Department of Natural Resources (DNR) began receiving numerous citizen complaints. COmplaints expressed conerns about damage to intermal combustion engines, reduced automotive performance, and health effects of the reformulated gasoline. Because of questions about health effects, along with a lack of information on exposure to urban populations, the DNR was asked to immediately initiate an air monitoring study. This paper will report on how the monitoring study was conducted and the results of the study.
