What is air pollution?

 

     Air pollution occurs when harmful substances are introduced to the atmosphere that has negative impacts on living things and environment. It threatens our environment and health of living things. Polluted air contains a mixture of solid particles, liquid droplets and gases.

 

 Where it comes from?

    These pollutants can come from industries, motor vehicles, heating appliances and tobacco smoke.  It can come naturally like volcanoes. 

 

 

What will happen to living things?

     Health problems such as irritation of eyes, nose or throat, lung and heart disease will arise due to exposure to the polluted air for quite sometime.

                CARBON MONOXIDE

 

  What is carbon monoxide?

  Carbon Monoxide is an odourless gas that can be deadly and poisonous.

Where it comes from?

 

  It is produce when there is incomplete burning of certain fuels like coal, wood, charcoal, oil and many others.

 

What are the effects?

 

     It harms the environment and human health. Inhaling too much carbon monoxide cause humans to be fatigue, shortness of breath, nausea and dizziness.More serious cases of inhaling large amount of carbon dioxide could lead to mental confusion, vomiting, loss of muscular coordination, loss of consciousness and even death. ( could be affected by the duration of exposure to the amount of carbon monoxide)

 

How to prevent Carbon Monoxide poisoning?

 

-Appliances are installed and operated with regard of the manufacturer instruction.

-Check if theres any fluid blockage or corrosion in pipes or any loose connection.

-Have clear knowledge of fuel burning appliances.

-Never burn charcoal indoor area like house or garage.

-Never leave a car engine on and left it.

 

What benefits can carbon monoxide do?

 

It can be use as a preservative, wine making or even a reducing agent.

 

Here's a video to tell you more about carbon dioxide:

                                                Nitrogen dioxide

 

 

What is nitrogen dioxide?

Nitrogen dioxide is a reddish-brown gas with a pungent and irritating odour.

 

 

Where it comes from?

It comes from road traffic and fossil fuel combustion.

 

 

What are the effects?

Long term exposure to Nitrogen Dioxide may decrease lung function and increase the risk of respiratory symptoms like acute bronchitis, cough and phlegm.It can damage trees and crops, resulting in substantial losses. 

 

 

 

How to prevent Nitrogen dioxide poisoning?

- Improve energy efficiency  

Buying renewable energy 

- Turning off lights, computers, televisions, video games and other electrical appliances when not in use.                                      - Buying energy saving equipment.

- Taking public transport

                           Sulfur Dioxide

 

 

What is Sulfur dioxide?  

It is a toxic gas with a pungent, irritating, and rotten smell. 

What are the sources of Sulfur dioxide?

 

It comes from fossil fuel combustion at power plants and volcanic eruptions.It is also somtimes used as a preservative in dried fruits.

 

What are the effects of Sulfur dioxide?

 

High concentrations of sulfur dioxide can lead to breathing problems in asthmatic patients.Short terms effects includes and wheezing, chest tightness shortness of breath. Long terms effects includes respiratory illness, alterations in the lungs' defenses and aggravation of existing cardiovascular disease. It can also cause acid rain.

 

How to minimise the concentration of sulfur dioxide?

 

-decreasing the sulfur content of the fuel used

-Changing to a natural or eco-friendly fuel.

 

Here's a video to learn more about Sulfur dioxide:

                       Photochemical Smog

 

                                                                                                                               

 

What is Photochemical Smog?

 

Photochemical smog is a condition that develops when primary pollutants (oxides of nitrogen and volatile organic compounds created from fossil fuel combustion) interact under the influence of sunlight to produce a mixture of hundreds of different and hazardous chemicals. 

 

What forms Photochemical Smog? 

 

Nitrogen oxides - combustion of oil, coal, gas in both automobiles and industry

 

Volatile Organic Compounds (VOCs) 

- evaporation of solvents
- evaporation of fuels
- incomplete combustion of fossil fuels



 

What are the effects?


It will decrease the level of visibility. Health problems such as heart and lung problems, eyes and respiratory irritation may arise if exposed to the smog for very long.
