Aerosols or particulates are fine particles in the air and
can either be solid or a liquid aerosol. They are formed from a wide variety of
natural and anthropocentric sources like biomass burning, incomplete combustion
like black carbon, soil dust and sea salts. These are not good for the climate
and can cause changes like an extreme precipitation change. We use aerosols
around the house every day that are not harmful, but other aerosols can really
affect our lives. If there are more aerosols on the clouds and are reflecting
the suns heat it can lead to world global cooling.
At ground level, ozone is an air pollutant that damages human health, vegetation, many common materials, and is a key ingredient of smog. Ozone is the gas present in the atmosphere which has capacity to protect the living beings on the earth from the ultraviolet rays from the sun that are harmful. Ozone has the same chemical structure (O3) whether it occurs miles above the earth or at ground level. At ground level, "bad" ozone is formed when certain compounds react in the presence of direct sunlight. Ozone may aggravate chronic lung diseases such as emphysema and bronchitis and reduce the immune system's ability to fight off bacterial infections in the respiratory system
