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 .

An air pollution source. The AP 42 Compilation of Air Pollutant Emission Factors is a compilation of the US Environmental Protection Agency (EPA)'s emission factor information on air pollution, first published in 1968. As of 2018, the last edition is the 5th from 2010.
Texas has the dubious distinction of leading the nation in polluted waterways. A new report draws upon self disclosed data by industrial facilities provided to the EPA. The study counted 17 ...
A 2020 paper reported that about half of air pollution and half of the resulting deaths are caused by emissions from outside a given state's boundaries, typically from prevailing winds moving west to east. [9] Regulation of air pollution is a shared responsibility between federal, state, and local governments.
In 2019, approximately 21,000 facilities reported releasing 2.16 billion pounds of these chemicals onto land, 580 million pounds into the air, and 201 million pounds into water sources. Exposure to these pollutants can lead to various health problems, from short-term symptoms like headaches and temporary nervous system effects (e.g., "metal ...
1947 – Los Angeles Air Pollution Control District created; first air pollution agency in the US. 1948 – Federal Water Pollution Control Act; 1955 – National Air Pollution Control Act; 1959 – California Motor Vehicle Pollution Control Board created to test automobile emissions and set standards.
Air pollution forecasting is the application of science and technology to predict the composition of the air pollution in the atmosphere for a given location and time. An algorithm prediction of the pollutant concentrations can be translated into air quality index , same as actual measurements.
A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
