| 摘 要： | 广东某地区的Cd污染严重,通过土壤地球化学测量,发现Cd污染区在空间分布上主要受地质背景控制,不同成因的地质体Cd含量具有明显的差异。根据对污染区的农作物、人发的调查,Cd的不同相态对植物有不同的影响,其中离子相和水溶相容易被植物吸收,Cd对植物的影响主要受离子相和水溶相的浓度控制。土壤中Cd高含量区,人发中Cd含量也相对高。

| Abstract: | A certain area in Guangdong Province has suffered serious Cd pollution.Soil geochemical measurements revealed that the spatial distribution of Cd-polluted area is controlled mainly by the geological background.Geological bodies of different origins show significant differences in Cd contents.According to the investigations on local crops and human hairs,it was found that different species of Cd have different influences on the plants,and the ionic and water soluble species of Cd are more easily absorbed by plants.The impact of Cd on plants is controlled by the concentrations of ionic and water soluble species of Cd.IN case that soils have high contents of Cd,human hairs also have relatively high contents of Cd. |
