Study Notes

Smog

Dr Henry Antoine coined the term "smog" and described its layers.
Smog is a mixture of fog and smoke.
Smog is caused by pollutants from incinerators and vehicle emissions.
Ozone is a secondary air pollutant.
Fly ash is a particulate pollutant.
Sulphur dioxide is responsible for turning the Taj Mahal yellow.

Air Pollution

The Air Quality Index (AQI) predicts ozone levels.
Primary pollutants contribute to 90% of global air pollution.
Five primary pollutants: smoke, fumes, ash, dust, nitric oxide and sulphur dioxide.
Secondary pollutants are produced by reactions between primary pollutants.
Examples of secondary pollutants: ozone, smog, sulphur trioxide, nitrogen dioxide.
Industries that contribute significantly to air pollution: brick manufacturing, gas manufacturing, and electrical goods industries.
Nitrogen gas is the most abundant gas in the air at 78%.

Health and Environmental Effects of Air Pollution

Increased air pollution leads to respiratory problems.
Air pollution affects heritage monuments.
Greenhouse gases: methane and carbon dioxide.
Air pollution can contribute to global warming.
Non-biodegradable pollutants: DDT and aluminum cans.

Diseases Caused by Smog

Rickets
Bronchitis
Breathing problems
