In each country with high concentrations of particulate matter, we have to also look at the composition of the pollutants that make up the matter. This can include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and flourinated gases. All of these pollutants in high concentrations can effect living conditions and cause health problems.
With these 4 pollutants, we will see the concentration of them in each country and compare them to GDP to analyze if there is a correlation in the type of pollutant and the GDP per capita that a country has.
The gases, compared to the concentration of PM2.5, seem to not really correlate at all to each other. The only outliers in this case were America, China, and the countries in Europe, as it was seen that with lower concentrations of PM2.5, there were higher concentration of pollutants in general. What it did seem though were that the pollutants were more distributed across while concentrations of PM2.5 were more localized. Carbon dioxide is also the highest pollutant that is present out of all the four, with its concentration being seen mostly in China and America.
China and the United States were the highest in terms of pollutants in all four of the graphs, and they also have the highest GDP. To find a correlation between GDP and pollutants, we can put the data in a scatter plot to find a correlation
There is a positive correlation between pollutants and GDP of each country, as it seems that with more GDP, the more emissions that are created. The trend of the emissions goes from carbon dioxide being the highest, then methane, nitrous oxide, and flourinated gases. With this correlation, the top five countries that emit the most gases that have the highest GDP are the United States, China, Russia, Korea, and India.
Looking at the pollutants that are emitted in correlation to GDP, we also have to look at the sectors contributing to these emissions to understand why GDP contributes to higher emissions.
