At the ecosystem level, air pollution can shift the competitive balance among the species present and may lead to changes in the composition of the plant community. The impacts of air pollution can vary depending on the type and concentration of pollutant released. [20] In agroecosystems these changes may be manifest in reduced economic yield. [21]
In 2008 the World Health Organization (WHO) and other organizations calculated that coal particulates pollution cause approximately one million deaths annually across the world, [29] which is approximately one third of all premature deaths related to all air pollution sources, [50] for example in Istanbul by lung diseases and cancer. [51]
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 .

A great many computer programs for calculating the dispersion of air pollutant emissions were developed during that period of time and they were called "air dispersion models". The basis for most of those models was the Complete Equation For Gaussian Dispersion Modeling Of Continuous, Buoyant Air Pollution Plumes shown below: [4] [5]
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 ...
Oil shale mining reduces the original ecosystem diversity with habitats supporting a variety of plants and animals. After mining the land has to be reclaimed, process takes time and cannot necessarily re-establish the original biodiversity. [3] [4] The impact of sub-surface mining on the surroundings will be less than for open pit mines ...
Air quality is considered satisfactory, and air pollution poses little or no risk. It's a great day to be active outside. 51-100 Moderate Yellow Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
