摘要
大气粉尘中的矿物主要来源于土壤尘、建筑工地和局地扬尘,颗粒较小,一般呈不规则形状,表面凹凸不平。矿物粉尘具有很强的生物活性,对人体健康、生物效应有其特有的生理作用。矿物粉尘表面活性基团影响粉尘的生物效应。矿物粉尘本身或刺激吞噬细胞而产生的自由基对细胞的损伤和粉尘性疾病的形成起着至关重要的作用。大气粉尘成分、表面特性以及矿物粉尘对人体正常宿主菌群的抑制性和毒性效应研究是矿物粉尘环境健康效应研究的重要方向。
Minerals in atmospheric dusts are mainly derived from soils, building dusts and rising dusts in some areas. The particles are characterized by small sizes, irregular shapes and surface unevenness. Mineral particles show strong biological activity, and exert a special physiological action to human health and biological effect. Surface activity groups of dusts affect their biological effects. Surface properties, free radicals released by mineral dusts or stimulated phagocyte play important roles in causing cell injury and pneumoconiosis. Atmosphere dust components, surface properties and the inhibition and toxic effects of mineral dusts on normal flora in human bodies are all important research aspects in the environmental health effects of mineral dusts.
