Theguardian.com reports about a new study on air pollution defining it as “the world’s single largest environment and human health threat”. The information gained through cellphone towers enables researchers to build up a picture of millions of New Yorkers’ movements during 120 days. They use a special formula which charts the density of population and levels of pollution to look at how people’s exposure to PM2.5, an airborne particle linked to an array of health problems, varies according to where they typically congregate during the day in contrast to other studies basing person’s pollution exposure on where they live.
The research has shown that areas of midtown and lower Manhattan, having some of the highest PM2.5 levels, saw a great number of people exposed during the day, whereas areas of southern Brooklyn peaked in pollution exposure at night as people returned after work.
According to the World Health Organisation (WHO), around 7 million people a year die as a result of air pollution, 200,000 of which accounts for the US as a result of fumes from cars, trucks and other transportation. Particles of PM2.5, being 30 times smaller than a human hair in width, are able to worsen asthma and heart diseases.
A study held by New York City found that annual average PM2.5 levels fell by ց in the six years to 2014 warning that the pollutants are still harmful for elderly people, children and people already having health problems.
A spokesman for New York’s mayor, Bill de Blasio announced that a goal has been set to make New York to have the cleanest air of any US city by 2030, by adding electric vehicles to the city fleet and making buildings more energy efficient.
