A forest fire is a natural disaster which consists of burning of forested area that damages the wildlife and affects the human health also.
Emissions from the forest fire can travel a long distance and can affect the air quality and biological health.
Volcanoes:
Volcanic eruption is one of the most important natural causes of air pollution.
The most problematic gases emitted in a volcanic eruption include sulfur dioxide, carbon dioxide and hydrogen fluoride.
Besides the volcanic gases, there is also volcanic ash. Volcanic ash can move hundreds to thousands of miles downwind from a volcano.
Fresh volcanic ash is gritty, rough and at times corrosive which can cause respiratory problems in human beings.
Volcanic eruptions can generate so much polluting gases and ash into the air that the sun’s rays could be blocked and land temperature in the affected area lowered.
Dust storms:
A dust storm or sand storm is a meteorological phenomenon common in arid and semi-arid regions.
Dust storms arise when strong wind blows loose sand and dirt from a dry surface.
Particles are transported by a process that moves soil from one place and deposits it in another.
