What causes brown haze?
What causes brown haze?
Atmospheric brown clouds are caused by emissions associated with the combustion of fossil fuels and biomass. The brown colour of the clouds results from the absorption and scattering of solar radiation by black carbon, fly ash, soil dust particles, and nitrogen dioxide.
Why is polluted air reddish brown?
Nitric oxide (NO) and nitrogen dioxide (NO2) are two gases whose molecules are made of nitrogen and oxygen atoms. These nitrogen oxides contribute to the problem of air pollution, playing roles in the formation of both smog and acid rain. It, along with aerosols, is responsible for the reddish-brown color of smog.
Which is an effect of the brown clouds that are now common in some parts of India?

What are the most common sources of air pollution?
There are four main types of air pollution sources:
- mobile sources – such as cars, buses, planes, trucks, and trains.
- stationary sources – such as power plants, oil refineries, industrial facilities, and factories.
- area sources – such as agricultural areas, cities, and wood burning fireplaces.
What is a common air pollution?
The common air pollutants are: Particulate matter (PM10 and PM2. 5) Ozone (O3) Nitrogen dioxide (NO2)
What are some examples of natural air pollution?
Naturally occurring pollutants include ash, soot, sulfur dioxide, ground-level ozone (also known as smog), salt spray, volcanic and combustion gases, and radon. These pollutants are released during volcanic eruptions, forest fires, and grass fires.
