The Capital on Sunday recorded an AQI of 407 (severe) at 4pm as per Central Pollution Control Board’s (CPCB) bulletin — the highest in 12 days, and a sharp departure from the recording of 294 (in the “poor” category) on Saturday.
If you own a petrol or diesel vehicle, you can look up engine information in RC (Registration Certificate). The registration certificate contains all of the information about your vehicle. It also contains information about the type of engine.
The AQI was a mild improvement from Monday’s 434 – with both recordings being the highest in two months, since air pollution first reached crisis levels due to smoke from farm fires and calm winds that are typical of pre-winter months.
