Grinding and sieving the soil did not change the average concentration, but lead to a significant reduction in heterogeneity (8–14%). This is apparently due to homogenization by mixing and grinding the clearly visible tar particles that presumably contained most of the PAH. Table 1. PAH concentrations in the untreated and treated soil in mg kg −1
