Air Pollution: Air pollution is spreading its legs everywhere. Increasing air pollution causes problems like cough, sore throat, respiratory diseases, burning sensation in the eyes and feeling tired in the body. A recent study has warned that there is no such place left in the world where the air is clean and pure. The air is becoming increasingly toxic. According to scientists, only 0.0001 percent of the world’s population is living in less polluted air. The air remains polluted in 70% of the days throughout the year.
This is the first such study, in which the air pollution of the whole world has been calculated. Scientists from Monash University Australia led this study. His report was recently published in The Lancet journal.
Pollution is double the standards
According to WHO, the daily exposure to PM 2.5 for any human being should not exceed 15 pg/m3. But in the years 2000 to 2019, its average was more than double. This study was done on the basis of data taken from 5446 monitoring stations in 65 countries, in which East Asia was found to be the most polluted. After this comes the area of South Asia and in the last is North Africa.
least pollution here
In the last two decades, the least pollution of PM 2.5 was found in New Zealand and Australia. After this in Oceania and South America. While air pollution levels have decreased in Europe and North America between 2000 and 2019, it has increased in Asia, New Zealand, South America and the Caribbean.
impact of climate change
Climate change also has an effect on air pollution. Where pollution increases in winter due to petrol-diesel in North West China and North India. At the same time, air pollution increases in summer on the east coast of North America. The reason for which is wild fire, which greatly spoils the air quality there.
Air quality researcher Yuming Guo of Monash University says that this study has come to know how much air pollution is outside. What is its effect on human health. With its help, governments will also be able to make rules and regulations.
