引言近年来,随着环境地球化学和生物地球化学的迅速崛起,环境中化学元素和微量成份的含量、形态、分布和迁移规律引起了许多学者的浓厚兴趣。这些领域的研究成果已在地质、农业、医药和环境保护等方面广泛地被应用,并取得了很大的社会和经济效益,其中一些植物样品中某些痕量元素分布的信息和资料,已开始用于探矿、中草药的药用和营养价值的评定、地方病病理和痕量元素与人体健康关系的研究以及环境污染源的确定等工作中。
Introduction In recent years, with the rapid rise of environmental geochemistry and biogeochemistry, the content, morphology, distribution and migration of chemical elements and trace elements in the environment have aroused great interest of many scholars. The research results in these fields have been widely applied in geology, agriculture, medicine and environmental protection, and have achieved great social and economic benefits. Some of the information and information on the distribution of some trace elements in plant samples have been Began to be used for prospecting, the evaluation of the medicinal and nutritional value of Chinese herbal medicine, the research on the relationship between pathology and trace elements and human health, and the determination of environmental pollution sources.
