The study concluded that “to date, no threshold level of PM is advised as safe for the general population,” adding that “current air quality standards need to be reassessed with consideration for efficient strategies to reduce air pollutants to as low a level as possible.”
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.
But actually tightening air quality standards — which would improve everyone’s health — may be challenging. Although the health benefits of large pollution reductions in major metropolitan areas are “widely acknowledged,” the study said, “there is policy resistance to actions that would further lower the concentrations of pollutants.”
Ponce, who was born in San Antonio, said he and his wife were living in a makeshift homeless camp nearby the El Paso area Walmart last August. He said he was inside the store when the shooting began. He and his wife have since moved to Memphis, where he works as a day laborer and […]
“In truth, we really don’t have the data in that granular fashion to be able to say that for every day that we had extremely bad air quality in the DMV, how many days, how many increased number of emergency room visits, for that matter, admissions to the hospital took place,” said Dr. Krupal Shah, […]
‘Let me start with the community in El Paso: That’s our community. That’s a Department of Homeland Security community,’ McAleenan said of the mass shooting. ‘There’s 4,000 families there protecting that border. They’re largely Hispanic, they’re primarily Hispanic.’
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.
“Ground-level ozone is produced when UV light reacts with pollutants from fossil fuels,” added Barr. “This process is accelerated by heatwaves, so ground-level ozone will likely continue to increase unless additional steps are taken to reduce fossil fuel emissions and curb climate change. But it’s not clear what level of ozone, if any, is safe for human health.”
To take a closer look at the possible impact of traffic-related air pollution, Beckwith and his colleagues performed MRI scans on 135 kids participating in a larger research project, the Cincinnati Childhood Allergy and Air Pollution Study, or CCAAPS. That long-term study recruited the families of children younger than 6 months old to examine the […]
