Question

note on natural sources of air pollutants

Answer 1

Air pollutants are emitted from a range of both man-made and natural sources including: burning of fossil fuels in electricity generation, transport, industry and households; ... natural sources, including volcanic eruptions, windblown dust, sea-salt spray and emissions of volatile organic compounds from plants.

Answer 2

Hello friend.....

Air pollutants are emitted from a range of both man-made and natural sources including:

burning of fossil fuels in electricity generation, transport, industry and households;

industrial processes and solvent use, for example in the chemical and mining industries;

agriculture;

waste treatment;

natural sources, including volcanic eruptions, windblown dust, sea-salt spray and emissions of volatile organic compounds from plants.

Air pollutants can be released directly into the atmosphere (primary emissions) or can form as a result of chemical interaction involving precursor substances.

The air pollutant emissions cause air pollution, however, reductions in emissions do not always automatically result in similar cuts in concentrations. There are complex links between air pollutant emissions and air quality. These include emission heights, chemical transformations, reactions to sunlight, additional natural and hemispheric contributions and the impact of weather and topography. Significant cuts in emissions are essential for improving air quality.
