On a sunny Friday morning in Mumbai, the air quality took a turn for the worse, reaching unhealthy levels according to real-time monitoring data at 8:30 am. The Air Quality Index (AQI) showed a reading of 183, well within the unhealthy range, causing concern for vulnerable groups within the city.
The main culprit for this decline in air quality was found to be the high levels of particulate matter, with PM2.5 levels at 100 micrograms per cubic meter and PM10 levels at 130 micrograms. These levels far exceeded the safe limits recommended by health authorities and pose a serious threat to the health of the general population, especially children, the elderly, and those with respiratory or cardiac conditions.
While other pollutants such as carbon monoxide, nitrogen dioxide, ozone, and sulfur dioxide remained within acceptable levels, the high levels of particulate matter alone were enough to cause breathing difficulties and eye irritation.
Despite the pleasant weather with a temperature of 26-27 degrees Celsius, humidity at 54%, and wind speed at 16 kmph, the atmospheric conditions were unable to prevent the accumulation of fine dust particles in the lower air layers.
Looking at the seven-day forecast, temperatures are expected to remain between 28-31 degrees Celsius with clear skies throughout the week. However, pollution levels are likely to remain volatile due to factors such as vehicular emissions, construction dust, and seasonal influences.
In light of these concerning levels of pollution, doctors are advising residents to limit their time outdoors, especially during the morning and late evening when pollution levels tend to be higher. Those experiencing symptoms such as coughing, throat irritation, or breathlessness are strongly encouraged to seek medical attention immediately. Additionally, the use of masks, air purifiers indoors, and staying hydrated has been highly recommended.
Environmental groups are once again calling on civic authorities to take preventive measures such as controlling road dust, strictly monitoring construction activity, and regulating traffic emissions. Citizens are also being urged to use public transportation and avoid unnecessary vehicular travel during peak hours.
As winter approaches, experts warn that Mumbai may experience more frequent unhealthy air days if immediate action is not taken to mitigate the issue.
