略论医学地质

医学地质主要研究地球上的无机物(元素、矿物、岩石等)和有机物(微生物等)对人类、动物和植物的作用和影响。这种作用和影响既包括致病的一面,也包括治病的一面,两者是辩证的统一体。研究表明:砷、汞、氡、石棉、晶质硅等地球物质及沙尘暴等均对人类健康造成危害。而通过对钙、磷等元素与人体骨骼的关系和元素-食物-心血管病关系的分析以及对某些人土食石习惯的探讨都清楚地证明了人体与地球的密切关系。地方病是医学地质研究的重点。我国在地方病防治工作中已取得重要成果。医学地质这一综合性边缘学科有着很大的发展潜力。

OUTLINE OF MEDICINAL GEOLOGY

Medicinal geology is a subject specializing in how inorganic matters (elements, minerals, rocks, etc.) and organic matters (microorganism, etc.) in the world act and effect on mankind, animal and plant. These action and affection can not only cause some diseases but also cure others, thus implying an argument of dialectical unity. Studies reveal that such inorganic substances as arsenic, mercury, niton, asbestos, crystal silicon, and even sandstorm, tend to be detrimental to health of mankind. Mankind, on the other hand, has countless ties with inorganic matters, as indicated in analyses of a relation of calcium, phosphorus, etc. to skeleton growth and in probe into an consequence of element-food-cardiovascular and cerebrovascular diseases. What is extremely emphasized by medicinal geology will be an endemic and in prevention and cure of it, we have achieved great successes. Medicinal geology, as a composite frontier science, will have great potentialities of development.
