AUTOMOTIVE EXHAUST EMISSION LEVELS BY GEOGRAPHIC AREA AND VEHICLE MAKE; A NATIONWIDE SURVEY

GROSS AVERAGE AUTOMOTIVE EXHAUST EMISSIONS DATA COLLECTED DURING THE SUMMER OF 1970 SHOWED ONLY SLIGHT GEOGRAPHICAL VARIATIONS WHEN THE SPECIFIC MAKES WERE IGNORED. WHEN CONSIDERING SPECIFIC MAKES, SIGNIFICANT DIFFERENCES WERE FOUND ON AN AVERAGE EMISSIONS BASIS. VEHICLE POPULATION-- EMISSION DISTRIBUTIONS SHOWED WIDE VARIATIONS IN THE 50 PERCENT POPULATION LEVELS AND IN THE PERCENT OF VEHICLES WITH EMISSIONS GREATER THAN SPECIFIED VALUES. HYDROCARBON (HC) AND CARBON MONOXIDE (CO) DATA ARE GIVEN ON A GROSS BASIS FOR THE 1970, 1968-69, 1966-67, AND PRE-1966 MODEL YEAR GROUP VEHICLES. AVERAGE HC AND CO EMISSIONS AND VEHICLE POPULATION--IDLE EMISSIONS DISTRIBUTION CURVES ARE INCLUDED FOR SPECIFIC MAKE VEHICLES IN SELECTED AREAS. /AUTHOR/
