Experts say that they found the world’s cleanest air, located in the Southern Ocean of Antarctica. Researchers and scientists from Colorado State University believe that the air in the Southern Ocean remains safe from human activity and dust from the continents of the world. They investigated the air components and its origin using the bacteria as a diagnostic tool to describe the properties of the lower atmosphere. The researchers also checked the composition of airborne microbes and examined the air in the marine boundary level, going to the south Antarctic ice border from Tasmania, Australia. Aerosols from distant landmasses and human activities were not moving south and into the air, appearing in a clear difference to all other studies from oceans, both in the northern hemisphere and subtropics.
