摘　　要：对上海市常见易生长的22种植物进行了现场采样测试,结果发现,瓜子黄杨、广玉兰、海桐、蚊母、墨西哥落叶杉及棕相对汞蒸气具有很强的吸收富集能力及抗毒性能。然后采用富集能力最强的瓜子黄杨进行一系列试验,结果显示,汞浓度随接触瓜子黄杨时间的延长而降低,而瓜子黄杨叶片的汞含量随时间的延长而增加。根据吸汞实验,计算得瓜子黄杨叶面积的吸气速率为0.133m’/h·m‘.Through investigation on 22 specie of common plants in Shanghai, it was found that Littleleaf Box, Southern Magnolia, Tobira Pittosporum, Pacemose Distylium, Mexican Cypress and Fortune Windmillpalm have great ability to absorb and enrich mercury vapour and anti-toxicity. The following experiment on Littleleaf Box which has the greatest ability of enrichment showed that concentration of mercury in the leaves of Littleleaf Box increased while the concentration of mercury vapour in indoor air decreased, and according to the absorbing experiment, the absorbing rate reached 0.133m3/h-m2.
