Abstract This study provides an optimization model that explicitly determines the ‘optimal’ level of pollution of fine particulate matter (PM2.5) by analyzing various options for reducing emissions from industrial and residential sources in the second largest urban area in Chile. Several conclusions that had not been previously addressed or sufficiently highlighted in the literature were discerned. The most notable conclusions included the importance of regulating all emission sources and not just industrial sources (which are typically fewer in number and easier to monitor), the homogeneity in ‘optimal’ levels of pollution from urban districts when considering the long-term effects on human health (which would support the adoption of uniform regulations), and the asymmetry in confidence intervals associated to the ‘optimal’ level of pollution.

确定工业和住宅来源产生的“最佳”污染水平 (PM2.5)

摘要 本研究提供了一个优化模型，通过分析智利第二大城市地区减少工业和住宅源排放的各种选择，明确确定细颗粒物 (PM2.5) 污染的“最佳”水平。一些先前未在文献中提及或未充分强调的结论被辨别出来。最显着的结论包括监管所有排放源而不仅仅是工业源（通常数量较少且更容易监测）的重要性，在考虑对城市地区的长期影响时，城市地区“最佳”污染水平的同质性。人类健康（这将支持采用统一法规），以及与“最佳”污染水平相关的置信区间的不对称性。
