Exposure to airborne particulate matter results in various adverse health effects. Unlike other pollutants, such as ozone, sulfur dioxide, carbon monoxide, and oxides of nitrogen, for which there is significant exposure, particulate matter exposure is much more complex because it is not a single chemical species or even a limited number of chemical species. Particulate matter includes various chemical species in particles having a wide range of diameters and shapes that have widely varying toxicities. People are exposed to particles in the ambient environment, in indoor spaces, and in the occupational environment. This article reviews the information available on the concentrations of particulate matter and its composition in these general environmental categories.
接触空气中的颗粒物会导致各种不良健康影响。与其他污染物不同，如臭氧、二氧化硫、一氧化碳和氮氧化物，人们对这些污染物有大量接触，而颗粒物接触则要复杂得多，因为它不是单一的化学物质，甚至也不是有限数量的化学物质。颗粒物包括粒径和形状范围广泛、毒性差异很大的颗粒中的各种化学物质。人们在环境、室内空间和职业环境中都会接触到颗粒物。本文综述了这些一般环境类别中颗粒物浓度及其成分的现有信息。
