Global multi-center study finds independent health risks of atmospheric nitrogen dioxide

Recently, an international research team led by Professor Kan Haidong of the School of Public Health of Fudan University has made important progress in the field of air pollution and health.

To this end, the Kan Haidong team relied on the "Multi-Country and Multi-City Study" (MCC) to collect environmental and health data from 398 cities in 22 countries and regions, and for the first time at the global level to study the relationship between daily nitrogen dioxide and daily mortality of residents.

Researchers found that exposure to nitrogen dioxide on the same day and the day before can significantly increase the risk of non-accidental death, death from cardiovascular diseases, and death from respiratory diseases; the effect of nitrogen dioxide remains after adjusting for coexisting pollutants such as PM2.

The corresponding author of the paper, Haidong Kan, said that the study systematically assessed the acute impact of nitrogen dioxide air pollution on the deaths of residents on a global scale, providing a scientific basis for the World Health Organization to revise the nitrogen dioxide air quality guidelines, and also for air pollution control.
