WebThe maps on this page show levels of nitrogen dioxide in the troposphere (the lowest layer of the atmosphere) over China. The maps above show NO 2 levels in central and eastern portions of the country from February 10–25 (during the quarantine) and April 20 to May 12 (after restrictions were lifted). WebNitrogen fixation is carried out by bacteria, algae and human activity, and once organisms have benefited from it, some of the nitrogen compounds break down and go back into the atmosphere as nitrogen gas. Along with top-ups from volcanic eruptions, the ‘nitrogen cycle’ has kept the level pretty constant for at least 100 million years.
