New Delhi, Nov 24 (NationPress) A hazardous layer of pollution enveloped the national capital, with the Air Quality Index (AQI) soaring to 396 on Monday, firmly placing it in the 'very poor' category. This represents a slight improvement from the 'very severe' AQI exceeding 500 observed across various hotspots in Delhi-NCR on Saturday.

Visibility decreased significantly in numerous areas of the city due to the thickening toxic haze, leading to renewed health alerts from authorities.

Nearby NCR cities are also grappling with poor air quality. Faridabad recorded an AQI of 358, Gurugram 370, Ghaziabad 355, Greater Noida 342, and Noida 372.

While most localities in Delhi are fluctuating between AQI 300 and 400, several areas have already surpassed the 400 threshold, plunging into the 'severe' category. Officials indicate that conditions may worsen if wind speeds remain stagnant.

Meteorologists link the rise in pollution levels to a mixture of still winds, low temperatures, and heightened moisture that trap pollutants near the ground. The winter inversion effect, where cold air remains trapped beneath warmer air, is obstructing the dispersal of particulate matter.

Environmental specialists warn that the ongoing presence of PM2.5 particles, the most harmful pollutants that can penetrate deep into the lungs, poses a significant health risk. Major contributors during this time include vehicular emissions, construction dust, industrial pollutants, and local biomass burning.

Healthcare professionals recommend that residents limit outdoor activities, particularly vulnerable groups like children, the elderly, asthma sufferers, and individuals with heart conditions. Prolonged exposure to current air quality levels can result in respiratory issues, eye irritation, diminished lung function, and a higher risk of cardiac problems.

With the AQI nearing the 'severe' zone, Delhi is under the scrutiny of the Graded Response Action Plan (GRAP). Authorities may implement stricter regulations if pollution levels continue to escalate, which could include restrictions on construction, bans on polluting vehicles, and suspension of specific industrial activities.

Experts assert that Delhi's recurring winter pollution dilemma necessitates long-term structural solutions beyond temporary fixes. These solutions include stricter enforcement of vehicle emissions, rapid public transport expansion, dust control at construction sites, and coordinated regional efforts to reduce external pollution sources.

As the capital faces yet another severe pollution episode, residents are cautioned that the upcoming weeks—usually the worst for air quality—could lead to further degradation unless weather conditions improve and emissions decline.

Delhi's annual smog crisis, now a seasonal public health emergency, continues to highlight the urgent need for enduring environmental reforms.
