摘要

TiTe welcome the opportunity to respond to O'Reilly et al.'s V V comment regarding our publications on coal-tar-based pavement sealants (CT-sealants) and polycyclic aromatic hydrocarbons (PAHs).1^5 In these publications, we identified CT-sealant as a major source of PAHs in urban settings on the basis of multiple lines of evidence: PAH diagnostic ratios in urban stream1 and lake sediments2 were similar to those in CT-sealed pavement dust; PAH profiles for lake sediment were highly correlated (r = 0.95) to those in CT-sealed pavement dust;3 source-receptor modeling attributed 50% of PAHs and upward trends in U.S. urban lakes to CT-sealant;3 and organic petrography identified particles of coal-tar pitch from CT-sealant in pavement and street dust, soils, and stream and lake sediments.5 In response to O'Reilly et al.'s suggestion that we "apply and compare the results of multiple source characterization techniques," we direct them to these publications. Additionally, we direct them to work by Watts et al.6 that recently identified CT-sealant as a major contributor of PAHs to stormwater on the basis of direct monitoring of loads and diagnostic ratios and principal components analysis (PCA).
