重金属在盐地碱蓬体内的累积与转移特征
The Accumulation and Transformation of Heavy Metal in
摘要
Abstract
In order to research the edible safety of Suaeda salsa(S.salsa) under accumulation and transformation of heavy metal,S.salsa in Tianjin coastal line land was selected for test. The result showed the had good accumulation ability of Pb, Zn with high transfer coefficient. Besides,S.salsa had stronger ability of Cu accumulation with low transfer ability. Though the contents of Pb and Zn in coastal wetland soil were higher, they didn't reach the pollution level. The comparison of metal contents in top soil and subsoil was showed as follows: Zn>Pb>Cr>Cu, and the contents of them were not meet the national soil environment standard. While the contents of Cr, Cu, Pb and Zn in root, stem and leaf of in line land were higher than the national organic green vegetable standard. Similarity, they couldn't meet the edible standard. Therefore, could be used for anti-pollution plant in costal wetland land with heavy metal pollution. However, the accumulation of heavy metal in plant illustrate that it couldn't be eaten any more. This paper provided the theoretical basis for development and utilization of in coastal wetland.关键词
