Stationary sources include:smoke stacks of fossil fuels and biomass power stations (see for example environmental impact of the coal industry)
burning of traditional biomass such as wood, crop waste and dung. (In developing and poor countries, traditional biomass burning is the major source of air pollutants.[23][24] It is also the main source of particulate pollution in many developed areas including the UK & New South Wales.[25][26] Its pollutants include PAHs.[27])
manufacturing facilities (factories)[additional citation(s) needed]a 2014 study found that in China equipment-, machinery-, and devices-manufacturing and construction sectors contributed more than 50% of air pollutant emissions[28]
waste incineration (incinerators as well as open and uncontrolled fires of mismanaged waste, making up about a fourth of municipal solid terrestrial waste)[29][30]
furnaces and other types of fuel-burning heating devices
Mobile sources include motor vehicles, trains (particularly diesel locomotives and DMUs), marine vessels and aircraft.
Controlled burn practices in agriculture and forest management. Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest.
There are also sources from processes other than combustion:

Fumes from paint, hair spray, varnish, aerosol sprays and other solvents. These can be substantial; emissions from these sources was estimated to account for almost half of pollution from volatile organic compounds in the Los Angeles basin in the 2010s.[31]
Waste deposition in landfills, which generate methane. Methane is highly flammable and may form explosive mixtures with air. Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia or suffocation may result if the oxygen concentration is
