Air pollution in indonesia!

In September - October 1997, fires in Indonesia were some of the most wide - spread polluting fires ever recorded. Basically forest fires were one of the main culprit, of which generates ash and smoke particles into the Earth’s atmosphere. Normally, such fires would die out with the monsoon rains at the end of September.But due to dry weather, fires continue to burn.

Human activity and regular dry periods, together with the El Niño-Southern Oscillation (ENSO), are now forming a "hot mix" which has led to devastating forest fires.



Causes of air pollution in Indonesia



Factories emitting waste and solid particles, motor vehicles emitting nitrogen oxides, carbon monoxides and hydrogen carbon also contributed to the large scale air pollution in Indonesia.


Carbon monoxide (CO). An odorless gas emitted from vehicles, particularly those without a catalytic converter. Some emissions result from industrial fossil fuel burning.
Lead. Emitted in particulate form by vehicles burning leaded gasoline, or from lead smelting and other metal processes.
Ozone. Created under certain weather conditions (sunny, still days) by VOCs and nitrogen oxides. Unlike the protective layer of ozone found in the earth’s stratosphere, ozone in the troposphere—where most plants and animals live—creates a photochemical smog and is highly toxic.
Volatile organic compounds (VOCs). Include hydrocarbons, alcohols, aldehydes, and ethers. VOCs play a role in ozone formation and are emitted by industrial processes and vehicles.















Due to consistent winds, haze from forest fires in Indonesia travelled to Singapore. This caused an unhealthy haze index, obstructing the daily lives of Singaporeans, and threatening us in many ways.Smog harms the human bodies which causes illnesses such as headaches,Asthma, and stinging eyes.Haze would contaminate water supplies, disrupt air flights, and daily lives of Singaporeans.Air pollution also causes ozone depletion which results in greenhouse effect. This increases the emission of the carbon dioxide which results in global warming.Airborne pollutants, especially sulphur dioxide and nitrogen dioxides from factories and power station, also produces acid rain when combined with clouds. Acid rain in turn destroys memorable structures, buildings, kills aquatic organisms and so on.
