超细矿物粉尘与人体健康

Superfine Mineral Dust and Human Health

环境学、地学和医学的相互结合符合资源合理利用与可持续发展原则,是研究矿物粉尘和人体健康的有机整体。该文根据矿物粉尘在大气中的行为特征、复杂性与环境自调节范围提出了5类粉尘环境,评述了矿物致病学说的不足,分析了无机粉尘自由基的生物学作用、形态及粉尘体内外作用的变化特征,最后提出,非职业环境的矿物粉尘的人体危害应当引起特别关注。超细矿物粉尘和纳米级永久悬浮粉尘是目前粉尘环境安全性评价的重大课题。

Most solid materials in nature consist of minerals, they are ubiquitous on the surface of the earth. After inhaled in body, they will trigger pulmonary disease. The pathogenesis of mineral dusts is always in the way of disputing and consummating. Researcher should pay great attention to the adverse effect of mineral dust in nonprofessional environment. The biological action of mineral surface is an important aspect to discover mineral dust interface function and molecular toxicological mechanism. At present, the superfine mineral dust and manometer suspending dust are the important components of dust environment safety assessment.
