Delhi air quality deteriorates sharply as AQI exceeds 300 mark

The national capital's air quality has taken a sharp turn for the worse, with the AQI climbing into the 'very poor' category as meteorological conditions shift unfavourably. The post-monsoon cleansing effect that had provided temporary relief to residents has dissipated, allowing pollutant concentrations to accumulate once again across the city.

Environmental monitoring agencies attribute the rapid deterioration to a combination of factors, including calmer wind patterns that prevent effective dispersal of particulate matter, and the seasonal transition that typically sees pollution levels spike in October and November. The breach of the 300-mark represents a significant health hazard, with residents advised to limit outdoor exposure and use air purification measures indoors.

The timing of the air quality crisis coincides with growing apprehension about the pollution surge that traditionally accompanies Diwali celebrations. The festival's fireworks and related festivities have historically exacerbated Delhi's air pollution crisis, pushing AQI levels to hazardous extremes in previous years.

Health experts have urged residents, particularly the elderly, children, and those with respiratory conditions, to exercise caution during outdoor activities. The deteriorating air quality is expected to persist in the coming weeks, with meteorologists indicating that substantial relief may only arrive with the onset of stronger winter winds or significant rainfall events.
