| Abstract |
Recent 1982 measurements of the nonmethane organic compound (NMOC) are reported for the Lincoln Tunnel. The NMOC levels in the tunnel were a factor of approximately 4 lower than 1970 levels. The decrease probably reflects reduced vehicular tailpipe emissions due to EPA hydrocarbon control strategy for photochemical ozone. Acetylene contribution to the total NMOC composition decreased almost by a factor of 2 from 1970 to 1982. The decrease was attributed to the preferential oxidation of acetylene by the vehicular catalytic device. New hydrocarbon component and sum of NMOC component ratios to acetylene are presented. These ratios are useful in the determination of hydrocarbon source emission contribution in urban and industrial areas. |
