AirQ+ is intended as a tool to ascertain the magnitude of the burden and impacts of air population on health in a given locality. [7] It performs this function by featuring data analysis, graphing tools, tables and quantitative information for prominent pollutants such as particulate matter (PM), nitrogen dioxide (NO 2), and tropospheric ozone (O 3).
The study found that people living in the most polluted city (Steubenville) were 26 percent more likely to die than those in the least polluted city (Portage), [7] [11] suggesting an association between particulate pollution and higher death rates in urban areas: "Although the effects of other, unmeasured risk factors cannot be excluded with ...
There are five types of air pollution dispersion models, as well as some hybrids of the five types: [1] Box model – The box model is the simplest of the model types. [2] It assumes the airshed (i.e., a given volume of atmospheric air in a geographical region) is in the shape of a box.
SAFE AIR II (Italy) – The simulation of air pollution from emissions II (SAFE AIR II) was developed at the Department of Physics, University of Genoa, Italy to simulate the dispersion of air pollutants above complex terrain at local and regional scales. It can handle point, line, area and volume sources and continuous plumes as well as puffs.
The Centre for Research on Energy and Clean Air (CREA) is a nonprofit think tank researching energy and air pollution. [1] CREA was founded in Helsinki in 2019 with the goal of tracking the impacts of air pollution by providing data-backed research products. [2] [3]
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 reports provide guidelines intending to give guidelines to reduce the health effects of air pollution. [ 2 ] The guidelines stipulate that PM 2.5 should not exceed 5 μg/m 3 annual mean, or 15 μg/m 3 24-hour mean; and that PM 10 should not exceed 15 μg/m 3 annual mean, or 45 μg/m 3 24-hour mean. [ 2 ]
[7] During haze episodes, PM 2.5 is the most significant pollutant. [8] The PSI is reported as a number on a scale of 0 to 500. The index figures enable the public to determine whether the air pollution levels in a particular location are good, unhealthy, hazardous or worse.
