土壤地球化学测量

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。

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 .
