Today is World Environment Day and this year’s theme is Air Pollution. It is one of the silent killers accounting for more than 6.4 million deaths per year.
Growing population and excessive consumption of energy through the transport system or heating, burning of fossils, industrial production, forest fires and air-conditions release enormous amounts of gases that are harmful to health.
These sources emit gases and substances like ozone(O3), Sulphur dioxide (SO2), nitrogen dioxide (NO2), benzopyrene (BAP) and suspended particulate matter (PM) that are toxic to human health.
Air pollution severely affects your physical, psychological health and disturbs regular bodily functions.
