Particle pollution is the mix of solid and liquid droplets in the air, according to the US Environmental Protection Agency. It can come in the form of dirt, dust, soot or smoke. It comes from coal- and natural gas-fired plants, cars, agriculture, unpaved roads and construction sites.
Researchers point to an increase in air pollution in Australian cities after massive bushfires ravaged the country. In the city of Richmond, west of Sydney, the levels of PM2.5 reached more than 500 micrograms per cubic meter — far surpassing levels deemed safe for humans to breathe. Earlier this month, NASA said smoke from the […]
Researchers analyzed air quality trends from that year back to 1999 at over 750 monitoring stations across the continental United States. They looked specifically at particulate matter — small, inhalable particles in the air that can enter the bloodstream.
Pictures of Emiliano Sala’s post-mortem examination emerged on Twitter two weeks after the crash, prompting the police to launch an investigation into the matter.

That compares with at least 140 air purifiers bought for $55,000 during 2014-2017 for the six ministries and Prime Minister Narendra Modi’s office, as previously reported by Reuters. The latest data on purchases for Modi’s office was not available.
“The increase in emphysema we observed was relatively large, similar to the lung damage caused by 29 pack-years of smoking and 3 years of aging,” said Dr. R. Graham Barr, the Hamilton Southworth professor of medicine and epidemiology at Columbia University Irving Medical Center and a senior author of the paper. One pack-year means smoking a pack of cigarettes a day for […]
‘Sea level is often communicated as a really slow process that you can’t do much about … but the next 30 years really matter,’ lead author Dr Matthias Mengel, of the Potsdam Institute for Climate Impact Research, in Potsdam, Germany, told Reuters.
“JetBlue is actually going a long way,” said CBS News meteorologist and climate specialist Jeff Berardelli. “Over the past 10 years, they’ve offset about 2.6 billion of their pounds of carbon — so the amount of carbon dioxide they’ve released into the atmosphere.

A limitation of this and other studies on pollution and brain development is that children living in areas with high pollution tend to be poorer than those who get to breathe clean air, Jack noted. But the fact that only certain brain areas appear to be affected suggests it’s actually the pollution exposure that is […]
