NEW DELHI: Delhi’s air quality improved slightly on Tuesday, but continued to remain close to the “severe” category with the overall Air Quality Index (AQI) being recorded at 378.

Delhi’s average PM 2.5 and PM 10 levels remained fairly high, recorded at four times the safe standard of 60 and 100 micro-grams per cubic meter. Data according to the CPCB showed Delhi’s average PM 2.5 levels at 260 micro-grams per cubic meter, while average PM 10 level was 439 micro-grams per cubic meter.

Delhi’s pollution levels once again came close to “emergency” levels under Graded Response Action Plan, which kicks in when both PM 2.5 and PM 10 levels stay above 300 and 500 micro-grams per cubic meter, respectively, for a period of 48 hours.
