| Abstract: |
| The petrochemical industry is one of the pillar industries in China. The pollutants，such as phthalates（PAEs），may be emitted into the atmosphere during the plastic production of the petrochemical industry. PAEs are one of the important plasticizers in the plastic industry，which are considered to be endocrine-disrupting chemicals for humans. However，few studies focus on the pollution of PAEs in the petrochemical industry，and there is limited understanding of the potential risks. In this study，PAEs in atmospheric particulate matter （TSP） at two petrochemical regions of Hainan（HNPB） and Guangdong （GDPB） provinces were analyzed. The results showed that the pollution level of PAEs in HNPB was significantly higher than that in GDPB，but both levels were generally lower than those in most cities in China. High PAEs concentrations in TSP were generally associated with the plastic industry，paper mill and ports. The average emissions of ∑PAEs for the major enterprises at two petrochemical regions were estimated using a simplified dispersion model，and the mass ranged from 0.48 to 191 kg for enterprises. The emissions mainly depended on the enterprise types. Health risks of humans for PAEs exposure were all under acceptable levels at two petrochemical regions. The correlations of PAEs in TSP largely depended on their similar applications and the coexistence in industrial products. Temperature，relative humidity and windspeed were the important meteorological factors influencing the concentrations of TSP-bound PAEs. This study is significant in providing the pollution characteristics，emissions，and influencing factors of TSP-bound PAEs at the petrochemical regions. |
