目的：在１９８７年４月～１９９２年３月伦敦空气污染短期影响的早先研究中，发现黑烟和臭氧与所有原因死亡率的关联性，但没有发现心脏－呼吸疾病死亡的特异性的确切证据。本文分析１９９２年～１９９４年伦敦资料以检验其间结果的一致性，并包括分析平均空气动力学直径为１?
PURPOSE: In previous studies of the short-term impact of air pollution in London from April 1987 to March 1992, the association of black smoke and ozone with all-cause mortality was found, but no exact evidence of the specificity of cardiac-respiratory disease death was found . This paper analyzes the London data from 1992 to 1994 to test the consistency of the results and includes an analysis of the average aerodynamic diameter of 1?
