Distribution Characteristics of Polycyclic Aromatic Hydrocarbons in Fine Particulate Matters in Proximity of a Large Chemical Industrial Park in Shanghai

    Abstract
  • Objective To measure the concentrations of polycyclic aromatic hydrocarbons (PAHs) in fine particulate matters (PM2.5) in proximity of a large chemical industrial park in Shanghai.

    Methods The concentrations of PM2.5 and 16 PAHs in PM2.5 were determined in area A (in 3km proximity downwind of the chemical industrial park) and area B (control, 30km away from the chemical industrial park) after consecutive three days of sampling in 3-5 June 2014.

    Results The concentration of total PAHs in area A was (13.64& #177;2.25) ng/m3, significantly higher than that in area B of (6.00& #177;1.59) ng/m3 (P<0.05). The concentrations of PM2.5 in area A and area B were (70.84& #177;15.35) μg/m3 and (85.74& #177;12.73) μg/m3 respectively (P>0.05). The weight of PAHs per gram of PM2.5 in area A (201.19 mg/g) was about 2.7 times that in area B (74.64 mg/g) (P<0.05).

    Conclusion The levels of PAHs close to the large chemical industrial park in Shanghai are higher than those away from this place.
