Occupational exposure to silica occurs at workplaces in factories like quartz crushing facilities (silica flour milling), agate, ceramic, slate pencil, glass, stone quarries and mines, etc., Non-occupational exposure to silica dust can be from industrial sources in the vicinity of the industry as well as non-industrial sources. Recently, public concern regarding non-occupational or ambient exposure to crystalline silica has emerged making it important to gather information available on non-occupational exposures to silica dust and non-occupational silicosis. This paper reviews various non-occupational exposures reported in literature including some studies by the author. Methodology used in assessment of non-occupational exposures, standards for non-occupational exposures to silica dust and indirect estimation of cumulative risk % are also discussed.
职业性接触二氧化硅发生在石英破碎设施（硅粉研磨）、玛瑙、陶瓷、石板铅笔、玻璃、采石场和矿山等工厂的工作场所。非职业性接触二氧化硅粉尘可能来自工业附近的工业源以及非工业源。最近，公众对非职业性或环境中接触结晶二氧化硅的关注日益增加，因此收集有关非职业性接触二氧化硅粉尘和非职业性矽肺病的现有信息变得很重要。本文回顾了文献中报道的各种非职业性接触情况，包括作者的一些研究。还讨论了评估非职业性接触的方法、二氧化硅粉尘非职业性接触的标准以及累积风险百分比的间接估计。
