[目的]比较研究9种河流沿岸植物对砷、汞的积累作用.[方法]采集水口山浯水段9种常见植物,测定植物及植物根际土壤中砷、汞的质量分数.[结果]植物对砷、汞的吸收因植物种类、部位、金属类型以及距离污染源的远近而不同,重金属在植物体内分布的多少顺序为:根>叶>茎;植物根部砷、汞平均质量分数分别为2.816、0.742 mg/kg,植物茎部砷、汞平均质量分数为0.891、0.056 mg/kg,植物叶部砷、汞平均质量分数为2.314、0.196 mg/kg;不同植物根部砷质量分数的大小顺序为:水蓼(Polygonum hydropiper)>三棱草(Scirpus yagara)>稗草(Echinchloa crusgalli)>苍耳(Xanthium sibiricum Patr.)>滨藜(Atriplex patens)>辽东蒿>芦苇(Phragmites australis)>曼陀罗(Datura stramonium)>鬼针草(Bidens bipinnata),茎部砷质量分数的大小顺序为:滨藜>水蓼>曼陀罗>芦苇>三棱草>稗草>辽东蒿>苍耳>鬼针草,叶部砷质量分数的大小顺序为:水蓼>滨藜>鬼针草>苍耳>芦苇>三棱草>曼陀罗>稗草>辽东蒿;不同植物根部汞质量分数的大小顺序为:三棱草>曼陀罗>滨藜>稗草>辽东蒿>芦苇>鬼针草>苍耳>水蓼,茎部汞质量分数的大小顺序为:芦苇>水蓼>稗草>曼陀罗>鬼针草>滨藜>三棱草>苍耳>辽东蒿,叶部汞质量分数的大小顺序为:水蓼>芦苇>鬼针草>曼陀罗>三棱草>苍耳>稗草>滨藜>辽东蒿.[结论]芦苇、滨藜、鬼针草、曼陀罗、苍叶对砷的吸收能力强,水蓼对汞的转运能力强.

[Objective] The research aimed to compare the accumulative effects of 9 common plants to arenic and mercury. [Method] In order to discuss heavy metal distribution characteristics in plants, arsenic and mercury concentrations of 9 plant species were determined from Shuikou Mountain. [Result] The results showed that arsenic and mercury concentrations in plants depended on species and distances to the pollution sources, and heavy metal concentrations of different plant organs were in the order of root>leaf>stem. The average arsenic and mercury concentrations were 2.816 and 0.742 mg/kg in plant roots, 0.891 and 0.056 mg/kg in plant stems, and 2.314 and 0.196 mg/kg in plant leaves, respectively. Arsenic concentration of different plants roots was in the order of Polygonum hydropiper>Scirpus yagara>Echinchloa crusgalli>Xanthium sibiricum Patr.>Atriplex patens>Artemisia verbenacea>Phragmites australis>Datura stramonium>Bidens bipinnata, arsenic concentration of different plants stems was in the order of Atriplex patens>Polygonum hydropiper>Datura stramonium>Phragmites australis>Scirpus yagara>Echinchloa crusgalli>Artemisia verbenacea>Xanthium sibiricum Patr.>Bidens bipinnata, arsenic concentration of different plants leaves was in the order of Polygonum hydropiper>Atriplex patens>Bidens bipinnata>Xanthium sibiricum Patr.>Phragmites australis>Scirpus yagara>Datura stramonium>Echinchloa crusgalli>Artemisia verbenacea.

[Conclusion] Phragmites australis, Atriplex patens, Bidens bipinnata, Datura stramonium, Xanthium sibiricum Patr. have the ability to absorb arsenic, Polygonum hydropiper has the potential to transfer mercury.
