Toxicological Risk Assessment

Recent occurrence and distribution of 16 priority polycyclic aromatic hydrocarbons (PAHs) proposed by USEPA in the northern Yellow River Delta (YRD) were studied based on the analytical data of 20 surface soil samples. The concentrations of 16 PAHs varied from 27.5 to 129 ng g-1 (dry weight). A clear tendency was observed that the total concentration of 16 PAHs is getting lower from west to the east in this area. The eco-toxicological risk assessment showed that this area is at low ecological risk region, which might not exert significant potential damage to the organisms. Four to six ring PAHs were predominantly from the coal and wood combustions in the whole area.
