The chart shows air pollution levels among four countries in 2012. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

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
