Researchers at the George Washington University Milken Institute School of Public Health have published the first quantitative study that links nitrogen dioxide (NO2 ) in traffic pollution and new cases of asthma in children ages 1-18 years. The authors suggest that the WHO guideline for NO2 may need to be re-evaluated to make sure it is sufficiently protective of children’s health. They also note that reducing air pollution by improving access to cleaner forms of transportation, like electrified public transport and active commuting by cycling and walking, would not only bring down NO2 levels, but would also reduce asthma, enhance physical fitness, and cut greenhouse gas emissions.

The first study to quantify the worldwide burden of new pediatric asthma cases linked to traffic-related nitrogen dioxide by using a method that takes into account high exposures to this pollutant that occur near busy roads.
