Scientists say they have found the cleanest air on Earth

Researchers at Colorado State University identified an atmospheric region that remains unchanged in the first study of the Southern Ocean bioresol composition. Human activity.
Weather and climate are closely linked, connecting each region of the world with other regions. E.g. Climate change Fast because of human activity, scientists and researchers fight to find one corner of the earth without being affected by humans.

But Professor Sonia Creedenweis and her team suspected that the air above the South Ocean would be at least affected by humans and dust from the world’s continents.

The researchers found that the boundary layer of air, which feeds the clouds above and below the Southern Ocean, was free of aerosol particles produced by human activity. – including the burning of fossil fuels, planting of certain crops, production of fertilizers and disposal of wastewater – or transportation from other countries of the world.

Air pollution Caused by aerosols, which are solid and liquid particles and gases suspended in air.

The researchers decided to study what was in the air and where it came from, using bacteria in the air as a diagnostic tool to determine the properties of the atmosphere below.

Thomas Hill, a research scientist and co-author of the study, explained that “aerosols that control the properties of SO (Southern Ocean) clouds are strongly involved in the biological processes of the oceans and appear to be isolated from Antarctica microorganisms and nutrient waste from the South.” Said in a statement.

“Overall, it suggests that SO is one of the very few places in the world that has been minimally affected by anthropological activities,” he added.

Scientists created air samples at sea level – the part of the atmosphere that has direct contact with the ocean – aboard a boat traveling south from Antarctic ice to Tasmania, Australia. Scientists then examine the combination of airborne germs, which are found in the atmosphere and often spread thousands of kilometers into the air.

From the bacterial fusion of germs, the researchers concluded that distant land masses and human activities such as aerosols caused by changes in land use caused pollution or soil emission were not traveling south and in the air.

Scientists say the results show stark differences between all other studies, ranging from the oceans to both the Northern Hemisphere and the subcontinent, where most of the germs came from the upper continent.

The survey, published Monday Activities of the National Academy of Sciences In the journal, scientists described the region as “truly primitive.”

According to the World Health Organization (WHO), air pollution is already a global public health crisis, and kills seven million people each year.

Studies have shown that the risk of air pollution increases Heart disease, Stroke and lung cancer.

The health agency says more than 80% of people living in urban areas that monitor air pollution are exposed to air quality levels, with health and the agency saying low- and middle-income countries suffer the most exposure.

However, studies have shown that air pollution can cross geographical boundaries and Affects people hundreds of miles away From where it originated.
