Original Source: A source mixing model to apportion PAHs from coal tar and asphalt binders in street pavements and urban aquatic sediments.
Present-day and more than 30years old road and footpath pavements from Auckland, New Zealand were analysed for PAHs to test the hypothesis that coal tar based pavement binders contribute to unusually high PAH concentrations in adjacent stream and estuarine sediments. Total PAH (∑(28)PAH) concentrations in the dichloromethane-soluble fraction ("binder"), comprising 5-10% of pavement mass, were as high as 200000mgkg(-1) (10000mgkg(-1) in binder+aggregate). Older and deeper pavement layers were strongly pyro...
