Exposure to ambient air particulate matter (PM) causes more mortality and morbidity than any other regulated environmental pollutant, but PM is ill defined (US Environmental Protection Agency, 2004). Although regulations to protect people from PM have progressively improved, the ultimate goal is to identify the components most responsible for adverse effects so regulations can be more targeted.
暴露于环境空气中的颗粒物(PM)造成的死亡率和发病率高于任何其他受监管的环境污染物,但 PM 的定义不明确(美国环境保护署,2004 年)。尽管保护人们免受 PM 影响的法规在逐步完善,但最终目标是确定对不良影响最负责任的成分,以便法规能够更有针对性。
