Air pollution measurement is the process of collecting and measuring the components of air pollution, notably gases and particulates. The earliest devices used to measure pollution include rain gauges (in studies of acid rain ), Ringelmann charts for measuring smoke , and simple soot and dust collectors known as deposit gauges .

The need for public institutions addressing environmental issues in Nigeria became a necessity in the aftermath of the 1988 toxic waste affair in Koko, Nigeria. [9] This prompted the government, led by President Ibrahim Badamosi Babangida, to promulgate Decree 58 of 1988, establishing the Federal Environmental Protection Agency (FEPA) as the country's environmental watchdog.
Air quality monitors are operated by citizens, [3] [4] [5] regulatory agencies, [6] [7] non-governmental organisations [8] and researchers [9] to investigate air quality and the effects of air pollution. Interpretation of ambient air monitoring data often involves a consideration of the spatial and temporal representativeness [10] of the data ...
The AQI made its debut in 1968, when the National Air Pollution Control Administration undertook an initiative to develop an air quality index and to apply the methodology to Metropolitan Statistical Areas. The impetus was to draw public attention to the issue of air pollution and indirectly push responsible local public officials to take ...
Operators must use the BAT to control pollution from their industrial activities to prevent, and where that is not practicable, to reduce to acceptable levels, pollution to air, land and water from industrial activities. The Best Available Techniques also aim to balance the cost to the operator against benefits to the environment.
For example, each year, more than 6 million people die prematurely from indoor and outdoor air pollution. Short-lived climate pollutants are largely to blame. Fast actions on short-lived climate pollutants, such as the widespread adoption of advanced cook stoves and clean fuels, have the potential to prevent over 2 million of premature deaths ...
Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike. Air pollution is a particularly big problem in emerging and developing countries, where global environmental standards often cannot be met. The data in this list refers only to outdoor air quality and not indoor air quality, which ...
Shade 1 is slightly grey and is usually categorized by air pollution boards as acceptable. It corresponds to an opacity of 20%. Shades 2, 3, 4 and 5 correspond to opacities of 40%, 60%, 80% and 100% (completely black) and are usually considered to be "black smoke" by air pollution boards of most countries.
