通过地方性病典型病区与非病区土壤化学成分和微量元素含量对比分析,初步掌握了病区土壤化学特征及微量元素分布特征,可作为探讨该病潜在环境病因的一种背景研究。
Through comparative analysis of soil chemical composition and trace element contents in typical ward and non-ward endemic ward, the chemical characteristics and distribution characteristics of trace elements in soils are preliminary mastered, which can be used as a background study to explore the potential environmental causes of the disease.
