Naduhatti, a small town nestled within the Tiruppur district of Tamil Nadu, India, occupies a relatively flat terrain at an elevation of approximately 285 meters. Its coordinates (11.4043°N, 76.8160°E) place it within the broader Kongu Nadu region, a historically agricultural heartland now experiencing significant industrial growth. The Noyyal River, a tributary of the Kaveri, flows nearby, though its water quality has been impacted by textile effluents. Naduhatti’s air quality is intrinsically linked to its position within this evolving landscape. Surrounding the town are extensive agricultural fields, primarily dedicated to cotton and vegetable cultivation, alongside a growing number of small-scale textile processing units – a characteristic of the Tiruppur knitwear cluster. This blend of agriculture and industry creates a complex pollution profile. The urban-rural gradient is relatively sharp; Naduhatti itself is a concentrated settlement, while the surrounding areas remain predominantly rural. The lack of significant natural barriers, like hills, means that wind patterns can readily transport pollutants both into and out of the town. Dust from agricultural activities, emissions from brick kilns (common in the region), and vehicular traffic all contribute to the local air quality challenges. The town’s location doesn’t benefit from strong coastal breezes, limiting natural dispersion.

Naduhatti experiences a tropical climate, broadly divided into a dry season (roughly November to May) and a wet season (June to October) influenced by the Southwest Monsoon. Air quality generally deteriorates during the dry season, peaking between February and April. Lower wind speeds and increased temperatures during these months promote temperature inversions, trapping pollutants near the ground. Dust from agricultural fields, prepared for summer planting, also contributes significantly. The monsoon season offers temporary relief, as rainfall washes away particulate matter and increased humidity suppresses dust. However, the monsoon can also bring localised flooding, disrupting traffic and potentially releasing pollutants from stagnant water. October and November often see a resurgence of pollution as post-monsoon conditions develop. Fog, common in cooler months, can exacerbate particulate matter concentrations. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the peak dry season months. During the monsoon, precautions should be taken to avoid waterborne diseases, as air pollution can interact with water quality. The transition months (September-October and May-June) are often characterised by fluctuating conditions, requiring increased vigilance.
