Abstract
A seventy-oven coke manufacturing plant has been surveyed for concentrations of cyclohexane-soluble coal tar pitch volatiles (CTPV) and benzo(a)pyrene (BaP). Three off-battery and three on-battery sampling sites were selected, with 45 samples collected during July, 1970. The on-battery locations showed measured levels of 0.0313 to 1.67 mg of CTPV and 0.172 to 15.9 μg of BaP per cubic meter; the off-battery concentrations were 0.0072 to 0.322 mg of CTPV and 0.021 to 1.18 μxg of BaP per cubic meter. Cyclohexane-soluble CTPV expressed here reflect higher benzene-soluble CTPV concentrations, since benzene is more polar than cyclohexane. BaP was determined analytically by spectrophotofluorometry preceded by instant thin-layer chromatographic (ITLC) separation of the cyclohexane-soluble residue in pentane. The influence of adjacent batteries and subsequent correlations with wind direction are also discussed.Keywords
