Air Pollution Control

Modernization paved the way for new technologies. Innovation on transportation, lifestyle and almost everything around us is occurring every day. However, it is our environment who is suffering from the comfort technology has brought us. Cars, factories and automobiles release hazardous gas causing air pollution that needs to be controlled.

Because of the increase in demand of goods, the supply from manufacturing companies has to catch up. New factories are built so we can achieve self-sufficiency. These factories have become the major source of outdoor air pollution in urban areas and have been regulated to do air pollution control. The air coming from the factories contains substances known as air pollutants harmful to humans and the environment. Pollutants can be classified into two: primary and secondary. Primary pollutants are those emitted directly through the process. Examples of which are the ashes from a volcanic eruption, carbon monoxide gas released by a motor vehicle and the sulfur dioxide coming from factories. Secondary are air pollutants emitted indirectly. They are formed when primary react or interact in the air.

There are primary pollutants produced by human activity. Sulfur oxide is produced largely through coal burning. It comes in volcanoes and in various industrial processes. Carbon monoxide is an odorless, colorless but very poisonous gas. It is created by incomplete combustion of fuel such as natural gas, coal or wood. Nitrogen oxide is emitted directly by automotives. It is considered as one of the most prominent air pollutants. Volatile Organic Compounds or VOCs are highly reactive organic compounds. It is categorized into methane and non-methane. Methane contributes to global warming. Other hydrocarbon VOCs are significant greenhouse for their ability in creating ozone and in prolonging the life of methane in the atmosphere. Particulate matters are ash, dust and salt particles that when breathed in can cause health hazards such as heart disease and lung cancer. Secondary pollutants include sulfuric acid H2SO4 that can cause respiratory problems and nitrogen oxide that gives air a brownish coloration.

Air pollution coming from factories and automobiles is something we can not set aside. Every business must have an air pollution control to prevent them from deteriorating what is left to our world.
