| 摘要: |
| 以煤矿区及煤矸石的污染特征为依据，选取16种EPA优先控制多环芳烃（PAHs）污染物，采用高效液相色谱法对不同堆积年限的矿区煤矸石山周围塌陷区的水体样品进行测试，分别分析此类水体中单个PAHs和总PAHs的分布情况及水体中PAHs不同环数的组成情况，并采用风险商值法进行水体生态风险评价，指出此类水体的不当开发利用会引起人体健康危害。 |

| Abstract: |
| According to the pollution characteristics of the coal mine and coal gangue hillock, 16 kinds of polycyclic aromatic hydrocarbon (PAHs) registered by EPA in subsidence water samples around coal gangue hillock were selected and detected by high performance liquid chromatography (HPLC). Distribution of single PAH and total PAHs and composition of rings number of PAHs were analyzed. Ecological risk assessment of such water body was carried on by risk quotient method and the results showed that unsuitable development of such water body may cause harm to human. |
