This paper reviews the ambient air literature and discusses the link between particulate matter with an MMAD < or = 10 micrograms (PM10) emissions and estimates of silica particulate concentrations. Silica appears to represent a range of 0.4-21% of PM10 emissions, although this estimation needs more research (including direct measurements) to contribute to increased confidence in the methodology.
本文回顾了环境空气方面的文献，并讨论了空气动力学直径小于或等于10微米的颗粒物（PM10）排放与二氧化硅颗粒浓度估算之间的联系。二氧化硅似乎占PM10排放的0.4%-21%，不过这一估算需要更多研究（包括直接测量），以增强对该方法的信心。
