Air Pollution
There are many types of pollution;
- Air Pollution
- Water pollution
- Land Pollution
Air pollution is a mixture of solid particles and gases in
the air. Car emissions, chemicals from factories, dust, pollen and mold spores
may be suspended as particles. Ozone, a gas, is a major part of air pollution
in cities. When ozone forms air pollution, it's also called smog. Some air
pollutants are poisonous.
Air pollution
can cause a variety of lung diseases and other respiratory problems. This chest
X ray shows a lung disease called emphysema in the patient's left lung. A
variety of things can cause it, including smoking and exposure to air pollution.
It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals and humans to survive as the air becomes dirty. Air pollution can further be classified into two sections- Visible air pollution and invisible air pollution.
Chemical reactions involving air pollutants can create acidic compounds which can cause harm to vegetation and buildings. Sometimes, when an air pollutant, such as sulfuric acid combines with the water droplets that make up clouds, the water droplets become acidic, forming acid rain.
Along with harming human health, air pollution can cause a variety of environmental effects: Acid rain is precipitation containing harmful amounts of nitric and sulfuric acids. These acids are formed primarily by nitrogen oxides and sulfur oxides released into the atmosphere when fossil fuels are burned.
