[Pollution Characteristics and Health Risk Assessment of Hazardous Air Pollutants in the Surroundings of Three Petrochemical Industries in Northwest China].

The samples in the surroundings of three representative petrochemical industries in Northwest China were collected by summa canister/adsorption using activated carbon/glass fiber filter, and then they were analyzed for 13 hazardous air pollutants by gas chromatography-mass spectrometry/gas chromatograph/high performance liquid chromatography. The pollution characteristics and human health risk of hazardous air pollutants were discussed. The results showed that 8 hazardous air pollutants existed in the surroundings of all petrochemical industries.
