Effects of pollutants

 Humans are today exposed to air pollution of all kinds. They are thus affected by the harmful effects of pollutants in the air they breathe. 

Vehicular exhausts cause air pollution: One of the major causes of air pollution is vehicular traffic. Vehicles of all kinds have multiplied across the country. Today traffic congestion on roads is very common. During peak and rush hours the traffic snarls are difficult to cope with for motorists and pedestrians. Commuting has therefore become difficult. Vehicles whether they are cars, buses, trucks, motorbikes, scooters or rickshaws are run on fuel. There is a process of fuel combustion that leads to the exhaust of poisonous compounds. It includes noxious gases and particulate matter. The harmful gases include hydrocarbons, nitrogen oxides, carbon monoxide and sulfur dioxide.

There are many causes of air pollution: Factories also contribute to air pollution. The smoke generated by factories is let out into the air thus polluting the air that we breathe. Similarly, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke. Production of electricity is also mostly through the process of burning non-renewable fossil fuels that leave dangerous smoke in the air. The burning of garbage also creates harmful smoke. Construction activity also creates particulate matter that pollutes air.

Air pollution affects us adversely: Today we are witnessing high levels of air pollution that affect the health of man and other creatures. People around the world are suffering from respiratory and cardiac problems, and various other diseases affecting other organs of the body. Air pollution also causes cancer. Millions of people around the world die each year due to air pollution.

The gases that cause air pollution are also greenhouse gases, and have caused global warming and climate change that affect the Earth and its ecology.
