人类的生活与健康同周围环境有密切的关系。根据有无人类活动的参与,人类生活环境可分为原生环境和次生环境。由于自然条件不良所引起的地方病,属于原生环境问题;由于环境受到人为的污染所引起的有关环境污染病,属于次生环境问题。现分别介绍这两方面有关的参考资料。生物地球化学性疾病在地质历史发展过程中,逐渐形成了地壳表面元素分布的不均一性,在一定程度上控制和影响着世界各地区人类、动物和植物的发育,造成了生物生态的明显的地区性差异。由于自
Human life and health are closely related to the environment. According to the presence or absence of human activities, human living environment can be divided into primary environment and secondary environment. Endemic diseases caused by poor natural conditions are primary environmental problems; secondary environmental problems are caused by environmental pollution caused by environmental pollution. The respective reference materials on these two aspects are introduced separately. Biogeochemical disease gradually formed the heterogeneity of the elemental distribution on the crustal surface during the geological history development and controlled and influenced the development of human, animals and plants in various regions of the world to a certain extent, resulting in obvious bio-ecological Regional differences.
