Particulate matter or PM pollution refers mostly to dust and tiny particles varying from ~ 0.01 microns - 1000 microns. The composition of particulate matter can be anything from inorganic particles ...

Collectively, all particles smaller than 2.5 micrometers (PM 2.5) are known as fine aerosols. Particles with diameters between 2.5 and 10 micrometers are correspondingly known as coarse and ...

Particles as a Direct Source of Free Radicals Urban PM, diesel exhaust particulate and other carbon-based particles generate super oxide free radicals in physiological solutions in the absence of ...

Human health and climate change are unquestionably linked. The earth has a fever and the prescription is reducing greenhouse gas emissions by transitioning to a clean energy economy. It is the most ...

A new study suggests that fine particulate matter (PM1) in Delhi may be absorbing moisture from the humid winter air, leading ...

The researchers were particularly interested in the smallest particles, of PM2.5 and below (often referred to as fine PM) -- 30 times smaller than the diameter of a human hair. These tiny ...
