The subjects that I am going to focus on are climate change and chemistry. The interdisciplinary topic I am going to focus on is air pollution.

Air Pollution –  the presence of substances in the air that are harmful or has poisonuss effects

Question 1:      What reactions are the main causes air pollution?(chemistry)

Burning fossil fuels creates many chemical reactions in the air that cause air pollution.

Question 2:      What chemicals cause air pollution?(chemistry)

These are the main chemicals that cause air pollution in Canada.

AirPollutionSources

Gaseous hydrocarbons: molecules are made up of carbon linked by chemical bonds with hydrogen. Some examples include:

hydrocar

Nitrous Oxides(NOx):

N2O1-10024972

Carbon Monoxide (CO): is also known as the “silent killer” and can be very hazardous to our health.

Particulates (Atmospheric particulate matter): are tiny pieces of solid or liquid in the Earth’s atmosphere that can occour naturally from things like volcanoes, dust storms, and forest fires. 

Sources of Particulate Matter

Question 3:      How is Ozone formed in the Troposphere?(chemistry)

Ozone(O3) is very toxic and negatively effects our health, it also damages buildings.

The reaction that takes place looks like:

CO + 2O2 + hν → CO2 + O3

Question 4:      How is acid rain formed?(chemistry)

Acid rain is precipitation with high acidity levels.  It can damage plants, animals, cars, and buildings.

Question 5: How does air pollution contribute to the greenhouse effect?(climate change)

This graph shows the main greenhouse gases in the US

Many air pollutants contribute to the greenhouse effect.

Question 6: What is the trend in the concentration of sulphur dioxide over the past decades?(climate change)

 

SO2 levels in Canada over the years, it has been constantly decreasing.

SO2 levels in Canada over the years

 

sulphur dioxide levels has decreased drastically since 1970

Question 7: How does air pollution interact with the climate?(climate change)

Air-pollution-and-climate (1)

Air pollution and climate change greatly effect each other, many pollutants also lead to global warming.

Question 8: How can we reduce air pollution?(climate change)

Using less cars:

Turn off Air Conditioners and Heaters:

Turn off lights:

All these can release many harmful gases.
