Air pollution: The silent killer called PM 2.5
Air pollution varies greatly in different parts of the world, but across the globe, particulate matter (PM2.5) pollution is responsible for an estimated 4.2 million deaths every single year. In order to assess the global protection from it, researchers from McGill University set out to investigate global air quality standards.
The researchers found that where there is protection, standards are often much worse than what the the World Health Organization considers being safe.
“Our findings show that more than half of the world urgently needs protection in the form of adequate PM2.5 ambient air quality standards. Putting these standards in place everywhere will save countless lives. And where standards are already in place, they should be harmonized globally,” – says Yevgen Nazarenko, a Research Associate at McGill University.
