可吸入矿物细颗粒物与微生物的相互作用

The interaction between inhalable mineral granules and microorganisms

矿物细颗粒物和微生物个体都是大气颗粒物(PM)重要组成部分,它们在形态、共生关系和空气动力学行为上均有高关联度。本文对可吸入颗粒物(IP)和可吸入矿物细颗粒(IMG)的颗粒特性、自由基和生物活性、IP和IMG与微生物相互作用效果的研究现状做了阐述,指出大气颗粒物与微生物的相互作用的重要性。提出今后应重点研究可吸入矿物细颗粒物的环境化学与微生物作用行为,研究IMG-微生物体系近尺寸作用体系中的尺寸效应、界膜作用等对矿物颗粒物表面形态、表面电性、表面基团及自由基等的影响,分泌蛋白质与相变、元素变价、溶解(络合)的关系以及由此引起的颗粒物活性和生物毒性的变化等。

Both mineral granules and microorganism individuals are important components of atmospheric particulate matter （PM）,having high relationship in morphology,association and aerodynamic behaviors. This paper has expounded the granule characteristics,free radical and biological activity as well as the effect of interaction between IP,IMG and microorganisms and pointed out the importance of the interaction between atmospheric particles and microorganisms. In future,the emphasis of the study should be placed on environmental chemistry and microorganism behaviors,the size effect and boundary film effect in the near size effect system of the IMG-microorganism system on surface morphology,surface electrical property,surface group and free radical of mineral particles,the relationship of the secretion of protein to the phase transition,the element variable valence and the solution （complexation） as well as the diversification of particle activity and biological toxicity caused by these factors.
