海口和三亚椰树中的重金属元素研究及环境指示意义
Heavy Metals in Barks and Leaves of Coconut Trees and Its Environmental Significance in Haikou and Sanya Cities, Hainan Province
摘要
Abstract
In order to study the relationship of heavy metals between coconut trees(Cocos nucifera L.) and the environment, concentrations of Cd, Co, Cr, Cu, Ni, Pb, Zn, Ti and V in bark and leave samples of coconut trees in Haikou and Sanya cities were analyzed. The results show that coconut tree barks and leaves are subject to accumulate Cd, Cu, Pb and Zn. All the studied element concentrations in barks and leaves in Haikou are higher than those in Sanya except Cr and Ni in barks. Both in barks and leaves, the concentration of Pb is significantly higher in roadway sides. The contents of Co, Cr, Ni, Ti and V in the industrial district are almost higher than other areas. We also discussed the biological absorption coefficients (BAC) and elemental correlations between coconut trees and soils, which indicated that the distributions of heavy metals in plants are influenced by soils limitedly and also by their individual biogeochemical characteristics.关键词
