Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. [1]
Short-lived climate pollutants (SLCPs) have a relatively short lifetime in the atmosphere – a few days to a few decades – and a powerful warming influence on climate.. The main short-lived climate pollutants are black carbon, methane and tropospheric ozone, which are the most important contributors to the human enhancement of the global greenhouse effect after C
The air within an inversion aloft is very stable with very little vertical motion. Any rising parcel of air within the inversion soon expands, thereby adiabatically cooling to a lower temperature than the surrounding air and the parcel stops rising. Any sinking parcel soon compresses adiabatically to a higher temperature than the surrounding ...
Within the sciences, the word "contamination" can take on a variety of subtle differences in meaning, whether the contaminant is a solid or a liquid, [3] as well as the variance of environment the contaminant is found to be in.

It spreads fast and far on surfaces and through the air in tiny droplets of vomit. Most people fully recover, but only after days of misery. Because it mutates, people can get sick with a ...
The air quality in Malaysia is reported as the Air Pollution Index (API). Four of the index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) are reported in ppmv but PM 10 particulate matter is reported in μg/m 3. This scale below shows the health classifications used by the Malaysian government. 0-50 Good
