Surface soil (0-20 cm) from various agricultural sites in Laolongdong underground river basin was collected to determine the concentrations, compositional profiles, and sources of 16 priority polycyclic aromatic hydrocarbons (PAHs). PAHs were measured by GC/MC. The total concentrations of PAH16 rang...
