Electric cars are increasingly common due to their potential environmental benefits, but a new study suggests that high ...
Air pollution causes health problems and is attributable to some 50,000 annual deaths in the United States, but not all air pollutants pack the same punch.
The smaller particles could in fact be more harmful as they can get through the body's natural defenses and cause significant ...
The EPA released its decision to maintain the health-based standard for ambient air concentrations by not reducing the limit from 12 to 11 micrograms per cubic meter (μg/m 3).; The widely-respected ...
A groundbreaking 25-year analysis using satellite technology has now mapped PM 1 levels across the U.S., uncovering how wildfires, vehicle emissions, and industrial byproducts have shaped the air we ...
Particulate matter from gasoline engines is harmful to our airways, regardless of whether the engines are a bit older or comply with environmental standards. Fine dust particles allow pathogens to ...
In 1997, EPA revised the National Ambient Air Quality Standards (NAAQS) for particulates to create a new standard for fine particulate matter (PM 2.5). Even as states are working to comply with those ...
PM 2.5 — Particles up to 2.5 μm. These are likely to be particles from power plants, vehicle exhausts, wildfires, and other types of combustion. PM 0.1 — Particles up to 0.1 μm.
The researchers were able to calculate their submicron estimates based on the known ratios of what makes up PM 2.5 particles, which include seven main components such as sulfate, nitrate and mineral ...
Particulate matter involves a mix of solid particles and liquid droplets in the air. The variety found in Sarasota right now is PM2.5 - which are about 2.5 micrometers and inhalable. The advisory ...
