| 中文摘要: |
| 筛选识别成都市多环芳烃（PAHs）污染重点源和区域，采集57个土壤样品，利用人体暴露风险模型对16种PAHs的健康风险进行评价。结果表明：青白江工业集中发展区与新都工业集中发展区连片区局部有PAHs潜在渗漏风险，污染源主要为工业企业和交通源，农业面源、生活污染源等不直接产生PAHs；土壤PAHs主要来源途径为企业VOCs排放与沉降、汽车尾气与大气中PAHs沉降、废矿物油泄漏入渗；PAHs主要离去途径为入渗地下水、冲淋径流进入地表水、植物吸收；智能设备制造、化工用地存在PAHs人体健康及环境生态风险。 |
| 英文摘要: |
| 16 kinds of PAHs in 57 soil samples from the key pollution sources in Chengdu were evaluated by human exposure risk model. The results showed that there were potential risks of PAHs in Qingbaijiang Industrial Concentrated Development Zone and Xindu Industrial Concentrated Development Zone. Industrial enterprises， as well as traffic source， agricultural non point source and domestic pollution source which indirectly produced PAHs were the main sources. PAHs in soil mainly came from VOCs emission， vehicle exhaust， atmospheric deposition and waste mineral oil spill. PAHs mainly went into groundwater by infiltration， into surface water through runoff and were absorbed by plants. There were human health and ecological environment risks of PAHs in the land use of intelligent equipment manufacturing and ch〖GK0!23*3/4〗emical industry. |
