Extract

X-ray fluorescence (XRF) was required to analyze vehicle exhaust particulate samples deposited on filters to determine the trace element content of the emissions. These samples were collected as part of a study to assess the role of vehicular particulate emissions in the Denver “Brown Cloud” problem. This study was an adjunct to an earlier study of vehicular gaseous emissions at high and low altitudes. The earlier program involved complete certification testing of a fleet of twenty five (25) 1970, non-catalyst vehicles but did not include analysis of exhaust particulate emissions. Consequently, a subset of the original vehicles was selected for retesting at high and low altitudes. A complete analysis was necessary to compare the ratio of particulate carbon to lead in the vehicle particulate emissions at the Denver test site.
