Last year, due to the lockdown imposed due to Corona epidemic, there has been a slight decline in Delhi’s pollution, but despite this, Delhi is the most polluted capital in the world. This has been claimed in the World Air Quality Report released on Tuesday.
According to the report, Delhi’s air quality has improved by 15 per cent from 2019 to 2020. Despite this, Delhi has become the tenth place in the polluted cities of the world and the most polluted capital in the world. In the year 2020, the air quality of Indian cities recorded a 63 percent improvement.
The report ranked countries, capitals and cities based on PM-2.5. The three most polluted countries are Bangladesh, Pakistan and India, while the three most polluted capitals are Delhi, Dhaka and Ulaanbatore. The annual average of PM2.5 was found to be 84.1 micrograms per cubic meter in Delhi, while it was 77.1 and 46.6 micrograms per cubic meter in Dhaka and Mongolia’s capital, Ulaanbatore. Similarly, the three most polluted metros of India are Delhi, Mumbai and Bengaluru.
Worrying effect on health
According to the report, the impact on the health of air pollution remains worrisome. The report also records the impacts on air quality from the Kovid-19 lockdown, so the main reason for the decrease in pollution over the past year has been the imposition of the lockdown.
