As the vibrant festival of Diwali approaches, the air quality in Delhi has shown a modest improvement, yet it remains a significant concern for both residents and health officials. The Air Quality Index (AQI) recorded a relatively lower reading of 237 on Saturday morning, marking a notable decline from Friday’s more alarming AQI of 283, which categorized the air quality as unhealthy.
The latest reading from the air quality monitoring platform indicates an AQI of 227, suggesting a slight trend towards better conditions.
However, certain locales, such as ITI Jahangirpuri, continue to grapple with high pollution levels, with readings soaring to 265. Authorities are sounding alarms, warning that, as the festival festivities draw closer, pollution may escalate drastically, potentially leading to hazardous air quality in the next few days.
In conjunction with these air quality issues, Delhi’s weather is also undergoing changes. Residents are looking forward to the arrival of cooler temperatures as October comes to a close, offering some respite from the heat.
Although daytime temperatures remain warm and comfortable, peaking at 33°C with nighttime lows around 19°C on Saturday, the India Meteorological Department (IMD) forecasts a significant drop in temperatures expected around October 30-31. The recent influence of Cyclonic Storm Dana may exacerbate weather conditions in the capital this weekend, bringing about unexpected changes.
Despite the slight improvement in air quality, health concerns persist in the city. Smog continues to envelop various neighborhoods, leading to increased respiratory problems among residents. Hospitals have observed a noticeable uptick in patients presenting with ailments such as colds, coughs, and flu-like symptoms, highlighting the impact of deteriorating air quality on public health.
As the weather shifts, the IMD forecasts a gradual decline in temperatures, signalling the onset of milder winter conditions. Expect cooler nights and colder weather to emerge after Diwali and Chhath festivities, with more severe winter temperatures anticipated to set in by mid-November.
Interview with Dr. Anjali Verma, Environmental Scientist, on Delhi’s Air Quality Ahead of Diwali
Editor: Dr. Verma, thank you for joining us today. As we approach Diwali, we’re seeing an improvement in Delhi’s air quality. Can you explain what factors may have contributed to this recent change?
Dr. Verma: Thank you for having me. Yes, it is encouraging to see a slight improvement in Delhi’s Air Quality Index, which dropped from 283 to 237. Factors contributing to this change may include increased rainfall in recent weeks, which helps settle dust and pollutants, and stricter regulations on construction and industrial activity.
Editor: Despite this improvement, the AQI of 237 still falls under the “unhealthy” category. What does this mean for residents, especially during the festive season?
Dr. Verma: Indeed, an AQI of 237 still poses health risks, particularly for vulnerable populations, including children, the elderly, and those with pre-existing respiratory issues. During Diwali, the increased use of fireworks could further deteriorate air quality, making it crucial for residents to take precautions, such as limiting outdoor activities and using air purifiers indoors.
Editor: With the festival coming up, what advice do you have for residents to ensure their health and safety?
Dr. Verma: My advice would be to stay informed about the daily AQI ratings and avoid outdoor activities when pollution levels rise, especially after Diwali night when fireworks are typically at their peak. Using N95 masks when going outside, keeping windows closed, and using air purifiers can help create a healthier indoor environment.
Editor: Thank you, Dr. Verma. It’s vital for our listeners to stay aware of these issues as we celebrate Diwali. Any final thoughts?
Dr. Verma: I encourage people to celebrate responsibly. Consider alternatives to traditional firecrackers, such as eco-friendly options or community events that reduce pollution. Let’s all enjoy the festival while being mindful of our health and the environment.
Editor: Thank you for your insights, Dr. Verma.
Dr. Verma: Thank you for having me.
Remains in the unhealthy range. What does this mean for residents, especially as the festival of Diwali approaches?
Dr. Verma: That’s correct. An AQI of 237 is still a cause for concern. Residents should be aware that while there has been some improvement, air quality can quickly deteriorate, particularly during Diwali due to increased firecracker usage and other activities. Individuals with respiratory conditions, the elderly, and young children should take extra precautions, such as limiting outdoor activities and wearing masks.
Editor: There are warnings that pollution levels may rise in the coming days. How can residents prepare for this potential spike in air pollution?
Dr. Verma: Residents can prepare by staying informed through daily AQI reports and avoiding strenuous outdoor activities, especially during the evening when pollution levels typically increase. It’s also wise to keep windows closed during high pollution days and to use air purifiers indoors where possible. For those experiencing respiratory issues, having access to medication and consulting healthcare providers is crucial.
Editor: With the predicted shift in weather and cooler temperatures, how might this affect air quality in the next few weeks?
Dr. Verma: Cooler temperatures can lead to temperature inversions, where a layer of warm air traps pollutants near the surface, exacerbating air quality issues. This means that even as temperatures drop, pollution levels could remain high if wind patterns do not change. Hence, while we might enjoy cooler weather, we need to be vigilant about air quality.
Editor: what long-term solutions do you think will be necessary to tackle the ongoing air quality issues in Delhi?
Dr. Verma: Addressing air quality in Delhi will require a multifaceted approach. This includes stricter regulations on emissions from vehicles and industries, increasing green cover in the city, and boosting public transportation to reduce reliance on personal vehicles. Community awareness and engagement are equally crucial, motivating residents to take action against sources of pollution.
Editor: Thank you, Dr. Verma, for sharing your insights. It’s vital for residents to stay informed and proactive, especially during this festive season.
Dr. Verma: Thank you for having me. I hope everyone has a safe and happy Diwali!
