Pollution plumes in Paris air are richer in gaseous aromatic compounds than in LA; gasoline engines main source of VOCs

Green Car Congress

The study also shows that the proportion of gaseous aromatic compounds—apart from benzene—in hydrocarbon emissions is two to three times greater in pollution plumes in Paris than in Los Angeles, even though the total quantity of hydrocarbons emitted in Los Angeles remains considerably greater than in Paris.

Study estimates ~4M children worldwide develop asthma each year because of NO2 air pollution

Green Car Congress

NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health. The researchers estimate that most children lived in areas below the current WHO guideline of 21 parts per billion for annual average NO 2.
