Air pollution levels in Delhi on Monday dipped slightly, leading to a marginal improvement in the overall Air Quality Index (AQI) which was in the "very poor" category, that experts have attributed to moderate surface winds dispersing surface pollutants.

The air quality is likely to remain in the same category for the next two days, according to System of Air Quality and Weather Forecasting And Research (SAFAR).
