| 摘 要： | 通过采集和分析第二松花江中下游水和底泥样品,探讨了该河段水体中邻苯二甲酸酯(PAEs)含量及其分布特征。结果表明第二松花江中下游水体中PAEs以邻苯二甲酸二丁酯(DBP)和邻苯二甲酸双(2-乙基己基)酯(DEHP)两种为主。水中PAEs总量较高,DBP和DEHP含量均已超过我国地表水标准限值。底泥中PAEs总量与国内外一些河流底泥中的含量相近,但DBP和DEHP含量均已超过了美国华盛顿州的警戒标准。底泥中PAEs含量沿程分布总体上均呈现先增加后减少的特征;水体中PAEs含量及其分布特征主要受流域内工农业活动的影响。 |

| Abstract: | Content and distribution characteristics of phthalic acid esters (PAEs) were discussed by sampling and analyzing waters and sediments in middle and lower reaches of No. 2 Songhua River. Results showed that di-n-butyl phthalate (DBP) and di (2-ethylhexyl) phthalate (DEHP) were main PAEs in waters of the River. Total content of PAEs in water was high and the contents of DBP and DEHP exceeded the standard limit of surface water. Total content of PAEs in sediments was close to that of sediments in other rivers, but the contents of DBP and DEHP exceeded the alert criteria of Washington DC, USA. The PAEs content tends to increase first and then decrease along main rivers and the variation is influenced mainly by industrial and agricultural activities in drainage area. |
| Keywords: | No 2 Songhua River water body phthalic acid esters (PAEs) distribution |
