Neykkārappatti, a small town in Tamil Nadu, India, sits at coordinates 10.4489°N, 77.4627°E, nestled within the fertile plains of the state’s central region. With a population of approximately 15,970, the town’s geography is largely defined by its relatively flat terrain, typical of the Kaveri Delta region. The surrounding landscape is predominantly agricultural, dominated by rice paddies and other cultivated lands, reflecting the region’s reliance on irrigation from the Kaveri River and its tributaries. Neykkārappatti isn’t directly on the river itself, but benefits from the extensive canal network that distributes water throughout the area. This agricultural intensity contributes significantly to local air quality, through practices like stubble burning post-harvest and fertilizer use. The urban-rural gradient is pronounced; the town represents a concentrated settlement within a largely rural backdrop. While not a major industrial hub, the presence of small-scale brick kilns and agricultural processing units in nearby areas can contribute to particulate matter pollution. The town’s elevation is low, increasing its susceptibility to temperature inversions, which trap pollutants near the ground. Proximity to larger urban centres like Tiruchirappalli also means it can experience pollutant transport from those areas, impacting local air quality.

Neykkārappatti experiences a tropical climate, with distinct wet and dry seasons heavily influencing air quality. The dry season, from roughly February to May, sees a build-up of particulate matter due to dust from agricultural activities and increased reliance on biomass burning for cooking and heating. Temperatures rise during this period, exacerbating the effects of temperature inversions, trapping pollutants close to the ground. The pre-monsoon months of May and June are often the worst for air quality. The arrival of the southwest monsoon in June brings a temporary respite, washing away pollutants and increasing humidity, which settles dust. However, increased rainfall can also lead to localised flooding and mould growth, impacting respiratory health. Post-monsoon, from September to November, sees a gradual return of drier conditions and a resurgence of dust and agricultural smoke. The cooler, drier months of December and January generally offer the best air quality, though biomass burning for warmth remains a concern. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the dry season and periods of high dust or smoke. Monitoring local weather patterns and avoiding peak pollution times is crucial for protecting health.
