从吉隆坡及周边地区采锡活动产生的22个池塘中采集了10种水生植物。 砷在这些植物中的浓度部分反映了砷在池水中的浓度，范围从0.002至0.25 μ g ml-1。 一种水生植物黑藻对砷的吸收，是在实验室里研究的。 结果表明，吸收是一个函数的初始砷浓度。 在高磷浓度下，黑藻对砷的吸收受到抑制。 黑藻符合指示生物的标准，可作为水体砷污染的指示生物。
Ten varieties of aquatic plants were collected from 22 pools resulting from tin-mining activities in and around Kuala Lumpur. The concentrations of arsenic in these plants partially reflected the concentrations of arsenic in pool water, which ranged from 0.002 to 0.25-mu-g ml-1. Uptake of arsenic by one of the aquatic plants, hydrilla, Hydrilla verticillata Casp., was studied in the laboratory. Results indicated that uptake was a function of initial arsenic concentration. In the presence of high phosphate concentrations, uptake of arsenic by Hydrilla verticillata was inhibited. Hydrilla verticillata can be used as a bioindicator of arsenic pollution in the aqueous ecosystem as it fulfilled the criteria for an indicator organism.
