| 中文摘要: |
| 采用固相萃取-GC/MS法分析海河流域9个典型地表水水源地16种多环芳烃（PAHs）污染状况，结果显示除BkFL、BaP、InP、BghiP和DBA未检出外，其他11种PAHs均有检出。9个水源地春季水体中PAHs总值为238 ng/L~715 ng/L，夏季水体中PAHs总值为837 ng/L~278 ng/L，
表明PAHs季节性污染差异较为显著，夏季PAHs污染状况明显高于春季。PAHs的组成均以中低环芳烃（2~3环）为主，且Ant/（Phe+Ant）、Flu/（Pyr+Flu）和BaA/（BaA+Chr）比值显示9个水源地PAHs污染均来源于水源地上游煤炭、木材等燃烧产物。 |

| 16 kinds of Polycyclic aromatic hydrocarbons (PAHs) in 9 typical surface water sources in Haihe basin was analyzed by solid phase extraction gas chromatography/mass spectrometry. The results showed that 11 kinds of PAHs were detected except BkFL， BaP， InP， BghiP and DBA. The total concentration of PAHs ranged from 23.8 ng/L to 71.5 ng/L in 9 water sources in spring， and from 83.7 ng/L to 278 ng/L in summer. The concentration of PAHs had significant seasonal variation. PAHs pollution was more serious in summer than that in spring. The dominated PAHs were dicyclic and tricyclic aromatic hydrocarbons. According to the ratios of Ant/(Phe+Ant)， Flu/(Pyr+Flu) and BaA/(BaA+Chr)， PAHs pollution in the 9 water sources came from coal or wood combustion in the upstream of the water sources in Haihe basin. |
