With the decline in concentrations of suspended particulate pollution in Greater London the association seen in the 1950s and early 1960s between daily mortality and air pollution in the conurbation is no longer apparent. Associations between unusually cold weather and short-term increases in mortality have been noted; there appears to be a tendency for influenza epidemics to follow cold spells.
随着大伦敦地区悬浮颗粒物污染浓度的下降，20世纪50年代和60年代初在该城市地区观察到的每日死亡率与空气污染之间的关联已不再明显。人们已经注意到异常寒冷天气与死亡率短期上升之间的关联；流感流行似乎有跟随寒潮出现的趋势。
