Air pollution threat hidden as research ‘presumes people are at home’: study
Previous investigations fail to reveal impact of ‘world’s largest human health threat’ because they do not account for people’s movement, researchers say

The true impact of air pollution has been obscured by the failure to consider people’s exposure as they move around during the day, according to a new study that has mapped the hotspots of New York’s air pollution based on where people gather for work or recreation.
The research cites air pollution as “the world’s single largest environment and human health threat” but laments that the problem has not previously been “considered spatially and temporally”, with most studies basing a person’s pollution exposure on where they live.
