A period of cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday, 5 December to Tuesday, 9 December 1952 and then dispersed quickly when the weather changed. It caused major disruption by reducing visibility and even penetrating indoor areas, far more severe than previous smog events experienced in
1966 New York City smog researcher who had previously published findings on the death count of the 1953 and 1963 smogs—published a paper in October 1967 showing that the previous year's smog had likely killed 168 people. Greenburg showed that there were 24 deaths in excess of how many would normally be expected at that time of year every day, over a period of seven days—using a period four days longer than the smog itself had lasted because of the delay between smog exposure and resultant health effects. Greenburg said that his analysis could not account for damage during the smog that would remain latent
