Two studies recently published in the American Geophysical Union's journal Geophysical Research Letters found that the Covid-19 lockdown measures have a significant impact on global air quality. Particulate matter pollution has decreased in China and the levels of nitrogen dioxide – a gas produced from emissions from vehicles and industrial activities - decreased in China, Western Europe and America. Researchers also found that the average ground level ozone concentration has increased since March, a gas emitted by certain household and industrial products.
