This study investigated the occurrence,distribution,and risk of 55 target volatile organic compounds(VOCs)in water and soil samples from a chemical park and its adjacent areas.The concentrations of 55 VOCs in water and soil samples ranged from 1.22～1905.99 μg/g and 0～11.58 ng/g,respectively.Aromatic hydrocarbons were predominant in soil samples and halogenated aliphatic hydrocarbons were predominant in water samples.VOCs concentration in water samples collected at different sites was different by 1～3 orders of magnitude,and the average concentration of river water in the park was significantly higher than that of river water outside the park.However,risk quotient results suggest that VOCs pose a low risk to related,sensitive aquatic organisms in river water;the average concentration of VOCs in the soil in the park was slightly higher than that in the surrounding areas.
