Abstract

In April of 1975, General Motors proposed a study to measure potential sulfate exposures utilizing a fleet of catalyst-equipped motor vehicles in controlled, simulated highway driving conditions and under as many different meteorological situations as possible. At the request of GM, the U. S. Environmental Protection Agency (EPA) agreed to participate in the study, which was conducted at the GM Milford Proving Grounds in October 1975. (Mention of commercial products or company names does not imply endorsement by the Environmental Protection Agency. ) In this study, GM operated a fleet of 352 catalyst-equipped cars on their 10-km north-south straightaway. The cars ran for 2 hours at a speed of 50 km/h (50 mph), which is equivalent to a traffic density of approximately 5500 vehicles per hour on a four-lane highway. The gasoline used by the cars was unleaded and was blended to contain 0. 03 percent sulfur by weight. The study was conducted during October 1975 because several days with temperature inversions and low wind speeds were predicted for the test track site.
