SMOG is a word coined from Smoke and Fog. Though 'smog' is a familiar word for most of us, little do we know of its origin, causes and effects!
Origin and causes:
- Smog is typically a type of air pollutant.
- Smog can be caused by burning of large amounts of coal within a city, containing soot particulates from smoke, sulphur dioxide and other components.
- Modern smog is a type of air pollution derived from vehicular emission from internal combustion engines and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog.
- In certain other cities, such as Delhi, smog severity is often aggravated by stubble burning in neighbouring agricultural areas.
- Smog is a serious problem in many cities and continues to harm human health. Ground-level ozone, sulphur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions.
- It causes eye and nose irritation and it dries out the protective membranes of the nose and throat and interferes with the body's ability to fight infection, increasing susceptibility to illness.
- High level of respiratory issues and lung problems are reported every year in India.
Smog in Delhi:
China gets all the attention when it comes to terrible air quality, but the truth is that the worst day in Beijing is really just an average day in Delhi. Though it gets far less notice, the air in Delhi is some of the most polluted on the planet. In fact, India’s citizens have some of the weakest lungs, highest rates of asthma and highest mortality rates from respiratory issues of any nation in the world.
The latest set of statistics detailing Delhi’s air pollution has revealed that the Indian capital is smoggier than its Chinese counterpart for the second year running.
With little pressure on the government to resolve air quality issues from citizens or the media, Delhi’s air will continue to cause harm until people demand something better.
