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 ...

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 ...

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 ...

Anything smaller than 10 micrometres is called particulate matter. Ultrafine particles is the smallest part of particulate matter. It is smaller than 0.1 micrometres, which is 1,000 times smaller than ...

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 ...

Two decades ago, Chinese residents faced horrendous air quality, with concentrations of fine particulate matter (PM)—particles with a diameter smaller than 2.5 microns, known as PM 2.5—five to ...
