[Characters of greening tree species in heavy metal pollution protection in Shanghai].
In this paper, the stream banks nearby Qibao town and the factory area of Shanghai Baoshan Steel Company were selected as the typical areas contaminated by heavy metals. The polluted status was investigated by measuring the heavy metal concentrations of the sampled soils. The results showed that the heavy metal concentrations in the soils of stream banks were a little higher than the control, but obviously higher in the factory area of Shanghai Baoshan Steel Company. The growth status of the greening trees was recorded, and their heavy metal concentrations were measured by ICP. According to the research results and historic data, the excellent greening tree species mainly applied in polluted factory area were Viburnum awabuki, Lagerstroemia indica, Hibiscus mutabilis, Ligustrum lucidum and Sabina chinensis, which could grow well on contaminated soil, and accumulate high concentrations of heavy metal elements. The other tree species such as Distylium racemosum, Nerium indicum, and Photinia serrulata might be also available in greening for heavy metal pollution protection.
