Scientists have claimed that they have found the cleanest air place on earth. This air moves over the Antarctic Ocean at the southern end of the Earth. Scientists said that this air is the cleanest in the world. It is devoid of pollutants generated due to human activities.
The first research of its kind studied the bioaerosol of the Antarctic Ocean. Researchers at Colorado State University, during this time, discovered an atmospheric area that does not matter due to human activities. In this study published on Monday in the journal Proceedings of the National Academy of Sciences, scientists called the region truly sacred.
Air free of pollutant particles:
Researchers found that the air moving over the Antarctic Ocean was free of aerosols (particles suspended in the air) generated by human activities. Particles generated due to fossil fuels, harvesting of crops, fertilizers and wastewater disposal, etc. were not present in this air. These aerosols are the cause of air pollution. Aerosols are particles present in the air as solids or gases.
Scientists had to struggle for a long time:
Due to rapid climate change due to human activities, scientists had to struggle a lot to find a place on earth which is untouched by human activities. However, Professor Sonia Krydenwis and her team expressed the possibility that the air over the Antarctic Sea would be the least affected due to human activities and dust particles.
Thomas Hill, a scientist involved in the research and co-author of this study, said that aerosols control the properties of Antarctic ocean clouds that are also related to the ocean’s biological process. It seems that the Antarctic Ocean is isolated from the spread of microorganisms and nutrients from the southern continent.
Micro-organisms of the continents could not reach:
Scientists by sampling the air moving over the Antarctic Ocean found in the study of micro-organisms present in it that they originated in the sea. Based on the bacterial composition of these microbes, it was claimed that aerosols on far-away continents could not reach the air of the Antarctic Ocean. This study is in contrast to the earlier study which said that most micro-organisms spread through the air coming from continents.
Seven million deaths annually from air pollution:
According to the World Health Organization (WHO), seven million people die annually due to air pollution. Air pollution increases the risk of heart disease, stroke, and cancer.
80 percent of the city’s people are forced to take polluted air:
According to WHO, 80 percent of the city’s population is forced to take more polluted air. The situation of air pollution is severe in countries with low and medium economies.
