A groundbreaking study by atmospheric researchers has revealed where we can find the cleanest air on Earth.

Scientists from Colorado State University found the air over the Southern Ocean, close to Antarctica, is "truly pristine" thanks to being almost untouched by human pollution. In fact, the team discovered that the air was free from any particles produced by dust, dirt and human activity.

Researchers analysed the air within 24 miles of the Antarctic ice edge by sailing from Tasmania, but found almost no DNA as it was so incredibly clean.

"We were able to use the bacteria in the air over the Southern Ocean as a diagnostic tool to infer key properties of the lower atmosphere," Thomas Hill, co-author of the study told the BBC.

"Antarctica appears to be isolated from southward dispersal of microorganisms and nutrient deposition from southern continents. Overall, it suggests that the Southern Ocean is one of very few places on Earth that has been minimally affected by anthropogenic activities."

Elsewhere, a study last month found that the sky is a deeper shade of blue, thanks to lockdown and a slowdown in human activity. According to a climate professor at the University of Reading, pollution adds a layer of haze to the air, making the sky look paler than it really is. But, after a drop in global air and road travel, the once smog-filled sky is cleaner, clearer and bluer than ever before.
