Outdoor particulate pollution was the largest cause of death (4.7 million), followed by indoor air pollution (3.1 million) and ozone (0.5 million). [5] A study published in 2019 estimated that, for 2015, the number was around 8.8 million, with 5.5 million of these premature deaths due to air pollution from human sources.
Air pollution is caused predominantly by burning fossil fuels, cars, and much more. [4] Natural sources of air pollution include forest fires, volcanic eruptions, wind erosion, pollen dispersal, evaporation of organic compounds, and natural radioactivity. These natural sources of pollution often soon disperse and thin settling near their locale.
Air pollution in Los Angeles has caused widespread concerns. In 2012, the Public Policy Institute of California (PPIC) Survey on Californians and the Environment showed that 45% of citizens in Los Angeles consider air pollution to be a "big problem", and 47% believe that the air quality of Los Angeles is worse than it was 10 years ago.

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 ...
In European countries, air quality at or above 10 micrograms per cubic meter of air (μg/m 3) for PM 2.5 increases the all-causes daily mortality rate by 0.2-0.6% and the cardiopulmonary mortality rate by 6-13%. [35] Worldwide, PM 10 concentrations of 70 μg/m 3 and PM 2.5 concentrations of 35 μg/m 3 have been shown to increase long-term ...
Many areas, including major cities like London, are found to be significantly and regularly above legal and recommended pollution levels. [4] [5] Air pollution in the UK is a major cause of diseases such as asthma, lung disease, stroke, cancer, and heart disease, and it costs the health service, society, and businesses over £20 billion each ...
A pollutant or novel entity [1] is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts).
