Current Air Quality Snapshot
The air quality in Noida has recently seen a decline, registering an Air Quality Index (AQI) of 125. This level is categorized as 'Poor,' indicating potential health concerns for the general population,
and particularly for sensitive groups. The primary contributors to this degradation are elevated levels of particulate matter. Specifically, PM2.5 concentrations have reached 66 µg/m³ and PM10 is at 79 µg/m³. These fine and coarse particles are a significant factor in the reduced air quality. Additionally, ozone levels have climbed to 29 ppb, and nitrogen dioxide (NO2) stands at 9 ppb, both of which contribute to the overall air pollution. With the current temperature at 24°C, prolonged exposure to these conditions can exacerbate respiratory issues and lead to discomfort for many residents, especially those with pre-existing conditions.
Major Pollutant Breakdown
Delving deeper into the pollutants affecting Noida's air, particular matter remains the most significant concern. PM2.5, the finer of the two, is recorded at 66 µg/m³, while PM10, the slightly larger particles, are measured at 79 µg/m³. These particles, when inhaled, can penetrate deep into the lungs and even enter the bloodstream, posing serious health risks. Other notable pollutants include carbon monoxide (CO), which is present at 297 ppb, sulphur dioxide (SO2) at 2 ppb, nitrogen dioxide (NO2) at 9 ppb, and ozone (O3) at 29 ppb. While CO, SO2, and NO2 are also harmful gases, the elevated PM2.5 and PM10 levels are the primary drivers of the 'Poor' AQI classification. Understanding these specific components is crucial for implementing effective mitigation strategies and personal protective measures.
Weekly Air Quality Trend
Analyzing the air quality trend in Noida over the past week reveals a fluctuating pattern. As of March 19th, 2026, the AQI has seen its ups and downs. On March 12th, the AQI was 121, followed by 124 on the 13th, both categorized as 'Poor.' The situation slightly improved on the 14th with an AQI of 122, still in the 'Poor' range. A noticeable improvement occurred on March 15th and 16th, with the AQI dropping to 99 and 83 respectively, falling into the 'Moderate' category. However, the air quality deteriorated again significantly towards the end of the week. On March 17th, the AQI surged to 157 ('Poor'), and on March 18th, it reached 177, also classified as 'Poor.' This volatile trend highlights the dynamic nature of air pollution and the need for continuous monitoring.
Health Advisories and Precautions
With Noida's current AQI at 125, classified as 'Poor,' it is imperative for residents, especially those belonging to sensitive groups, to take necessary precautions. Individuals such as the elderly, children, and those with respiratory or cardiovascular issues may experience adverse health effects. Symptoms can range from throat irritation and coughing to more severe breathing difficulties. It is strongly advised to limit prolonged outdoor physical exertion. If outdoor activities are unavoidable, consider wearing a high-efficiency particulate respirator (N95 or similar). Staying indoors with air purifiers can also be beneficial. Vigilance regarding air quality forecasts and adherence to health advisories are key to safeguarding well-being during periods of degraded air quality.
