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.
Some Common Examples of Burning Fossil Fuels include:
Nitrogen Oxide (NOx):
Question 2: What chemicals cause air pollution?(chemistry)
These are the main chemicals that cause air pollution in Canada.
Gaseous hydrocarbons: molecules are made up of carbon linked by chemical bonds with hydrogen. Some examples include:
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.
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)
sulphur dioxide levels has decreased drastically since 1970
Question 7: How does air pollution interact with the climate?(climate change)
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.
