Atmospheric Index 2020

According to the Atmospheric Index 2020, 4 of the top 100 most polluted cities are in Bangladesh: Manikganj, Dhaka, Azimpur in Dhaka and Sreepur in Gazipur are ranked 16, 23, 60 and 61 respectively according to IQAIR's weather index. Of the top 100 polluted-air cities, 94 are in India, China and Pakistan. India tops the list with 46 cities, China is in second place with 42 cities.

Manikganj in Bangladesh is the 16th most polluted city in the world. In addition, three more cities and areas in the country are among the top 100 most polluted cities in 2020. These are Dhaka, Azimpur in Dhaka and Sreepur in Gazipur. These are ranked at 23, 60 and 61 respectively.

Switzerland-based IQAIR Air Quality Index shows the figure. Al-Jazeera reported this on Monday. IQAIR builds technology to help improve air quality. At the same time they monitor global air quality. According to IQAIR, air quality index is published every year.

According to IQAIR's Climate Index, 46 of the 100 most polluted cities are in India. China is in second place with 42 cities. The third most polluted country is Pakistan, with 6 polluted cities on the list. Bangladesh ranks 4th with 4 polluted cities or regions.

IQAIR reported 9 of the top 10 most polluted cities in 2020 are in India. However, the most polluted city is Hotan in Xinjiang, China.

The amount of air pollution in a region is determined by the levels of PM2.5, PM10, Ozone, Nitrogen Dioxide, Sulfur Dioxide and Carbon Monoxide. Airborne Particulate Matter (PM) has a negative effect on human body. If its level is below 12, it is considered not harmful. 55 to 150 levels are considered unhealthy and more than 250 levels are considered dangerous.

According to IQAIR's 2020 air quality index, the average PM of Manikganj was 80.2, it was 77.1 in Dhaka and 55.7 in Azimpur of Dhaka and Sreepur of Gazipur. In other words, the level of air pollution in four cities or regions of Bangladesh was at an unhealthy level. Hotan, the most polluted city in China, had an average of 110.2.

According to the Atmospheric Index 2020 and IQAIR, nine of India's top 10 most polluted cities are Ghaziabad, Bulandshahr, Bisrakh Jalalpur, Vibadi, Noida, Greater Noida, Kanpur, Lucknow and Delhi. These cities are ranked 2nd to 10th respectively.

According to a report in the medical journal Lancet, air pollution was the cause of 1.77 million deaths in India in 2019. According to various Indian media reports, the government of India or the country's Supreme Court has banned the burning of fireworks in the country every year.

However, this prohibition is not accepted. This year's Diwali festival also saw a huge fireworks display in Delhi without complying with the ban. In this situation, air pollution was at its peak in Delhi on 5 November. The Indian capital has had its worst day of the year, according to the weather index. PM 451 was the air pollution level indicator there that day.

In addition to burning fireworks, farmers in Punjab and Haryana burn crop residues on their land at this time of year. These two states are adjacent to Delhi. As a result, it is making the air pollution situation in Delhi worse. All schools in the 20 million population city of Delhi were closed last week.

Sunil Dahiya, an analyst at India's Center for Research on Energy and Clean Air on pollution and an observer of the Atmospheric Index 2020, said the ban on fireworks did not seem to work. Burning fireworks, along with other sources of air pollution, causes dangerous levels of pollution.

There are allegations against the Indian government for not taking appropriate steps to control air pollution. However, the governments of India and China are trying to control pollution by installing smog towers in their most polluted cities.

Two smog towers have been set up in Delhi following an order from the Supreme Court of India. The Smug Tower halves the level of PM2.5 from the air within a radius of one kilometer. Although many have questions about its effectiveness.

According to the World Health Organization (WHO), about 7 million people worldwide die each year as a result of air pollution. More than 90 percent of the world's population lives in areas above the pollution standards set by the WHO. Air pollution is associated with asthma, diabetes and heart disease.
