Especially without proper protections, heavy metals and other contaminates can seep into the soil, and create water pollution and air pollution. Historical deposition of coal ash used for residential, commercial, and industrial heating, as well as for industrial processes such as ore smelting , were a common source of contamination in areas ...
The January 2024 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 5,390 towns and cities in 63 countries. Air quality in the database is represented by the annual mean concentration of particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 micrometers, respectively). [1 ...
An air quality index (AQI) is an indicator developed by government agencies [1] to communicate to the public how polluted the air currently is or how polluted it is forecast to become. [2] [3] As air pollution levels rise, so does the AQI, along with the associated public health risk. Children, the elderly and individuals with respiratory or ...
Air pollution control system, known as a thermal oxidizer, decomposes hazard gases from industrial air streams at a factory in the United States. A dust collector in Pristina, Kosovo. Pollution control is a term used in environmental management. It refers to the control of emissions and effluents into air, water or soil.
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. [2] A contaminant may even be more abstract, as in the case of an unwanted energy source that may interfere with a process. [2]

The air quality in Malaysia is reported as the API (Air Pollutant Index) or in Malay as IPU (Indeks Pencemaran Udara). Four of the index's pollutant components (i.e., carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide) are reported in ppmv but PM 2.5 particulate matter is reported in μg/m 3.
The immense population growth in the People's Republic of China since the 1980s has resulted in increased soil pollution. [citation needed] The State Environmental Protection Administration believes it to be a threat to the environment, food safety and sustainable agriculture. 38,610 square miles (100,000 km 2) of China's cultivated land have been polluted, with contaminated water being used ...
