Abstract Air pollution meteorology related to the dispersion of toxic chemicals in the southeast Ohio River valley was analyzed for a 32-mo period. Attendant air quality measurements of benzene, benzo(a)pyrene, As, Cd, and Cr concentrations were also studied for a 24-mo period. Analysis of the meteorological data showed that wind flow in the valley is significantly affected by the synoptic wind pattern above the hilltop. Sampling at multiple stations showed that daily average concentrations were on the order of 7 μg m−3 for benzene, 2 ng m−3 for benzo(a)pyrene and As, 7 ng m−3 for Cd, and 20 ng m−3 for Cr. Correlations between different species concentrations ranged from 0.25 to 0.6. Based on multi-variable regression analysis, the average benzene concentrations were shown to correlate with the average wind speed and the morning and evening potential temperature gradients at the airport, with a correlation coefficient on the order of 0.5.
