Air pollution in the country's national capital Delhi is discussed all over the world, but now Mumbai is also not untouched by it. According to the report, the air quality in Mumbai has reached a very poor level. At some places in Mumbai, the air quality index crossed the 300 mark while at some places it crossed 200, which is considered to be the very poor level. The overall AQI level of Mumbai was recorded at 225 on Monday. While Delhi's overall AQI level was 152. These figures are from SAFAR (System of Air Quality and Weather Forecasting and Research) which has reported Mumbai's AQI level as poor. However, different places in Mumbai recorded different AQI levels. The air quality in Malad was 311 which is very poor. It was followed by 303 in Manjhgaon and Chembur. AQI level 269 was recorded in Bandra-Kurla.

According to the Central Pollution Control Board (CPCB), the air quality in Mumbai stood at 168 (moderate) and Delhi at 218 (poor). Now let's talk about why there is a difference between the figures of CPCB and SAFAR. In fact, SAFAR has monitoring stations at nine locations in the city while CPCB calculates the overall AQI based on 18 locations. On the other hand, CPCB has 36 air quality monitoring stations in Delhi.

A few days ago, the issue of Mumbai's poor AQI came up in a conversation between G20 Sherpa Amitabh Kant and Municipal Commissioner IS Chahal. While Chahal blamed the refineries and the Tata power plant for the major pollution, Kant on Monday said sulfur-dioxide emissions from the refineries were within prescribed norms. Kant, who also spoke to Union Petroleum Secretary M M Kutty, said the two refineries in the Mahul region have to ensure that they reduce sulfur emissions.
