The bar graph illustrates information about the level of air pollution in four different countries across three sectors in 2012. Overall, it is clear from the graph that China ranked first in all three factors, while the United States is primarily impacted by transportation as a significant cause of air contamination, and Japan’s main cause is factories or other industrial facilities, both of which ranked highest in two of the three parts.
Specifically, China’s air pollution levels are notably high, with all three sectors exceeding 50PPM, in contrast to the other three countries. Industrial facilities, such as factories and construction, account for a substantial majority of the contamination at 80PPM, followed by vehicles, including public transportation, at 70PPM, and electricity at 60PPM, which is more than double the amount of the second-ranked United States. In comparison, the United States is affected by electronic and industrial sources with an air quality impact of around 30PPM, while Japan shows similar impacts from transportation and significantly less from electronic consumption at 10PPM.
In Australia, the data indicates it as an environmentally conscious country, with its air pollution levels recorded at less than 20PPM in 2012.
