邻苯二甲酸酯(PAEs)是重要的塑化剂,也是石化行业排放的潜在污染物。然而,目前关于石化企业PAEs的污染研究很少,限制了对其潜在风险的认识。该研究对海南(HNPB)和广东(GDPB)两个典型石化基地周边大气颗粒物中的PAEs进行分析。结果表明,HNPB的PAEs污染程度高于GDPB,但两者均普遍低于我国大部分城市的污染水平;PAEs浓度较高的区域主要分布于石化企业和港口周边,主要企业的PAEs年排放量为0.48~191 kg,排放量与企业类型密切相关;两个石化基地周边人群经呼吸途径暴露于PAEs的风险均远低于风险阈值;用途和理化性质相似以及在工业品中共存是大气颗粒物中PAEs单体之间呈现良好相关关系的主要原因;温度、相对湿度和风速是影响大气PAEs浓度的重要气象因素。研究结果为进一步认识石化企业周边大气污染状况和潜在风险提供了依据。
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.
