Kaduturutti, nestled in the Kollam district of Kerala, India, occupies a geographically significant position within the state’s southern lowlands. Located at approximately 9.7833° N latitude and 76.3000° E longitude, the town’s terrain is predominantly flat, characteristic of Kerala’s coastal plains. The surrounding landscape is a mosaic of lush paddy fields, coconut groves, and interspersed rubber plantations, typical of the region’s agricultural dominance. Kaduturutti’s proximity to the Ashtamudi Lake, a sprawling and ecologically vital backwater, plays a crucial role in its microclimate and potential air quality dynamics. The lake acts as a natural sink, potentially mitigating some pollutants, but also contributing to humidity and fog formation under certain conditions. The urban–rural gradient around Kaduturutti is relatively gradual; the town itself is small, with a population of just over 21,000, transitioning seamlessly into the surrounding agricultural areas. While Kaduturutti itself lacks major industrial zones, it’s situated within a region experiencing increasing development, with nearby industrial belts in Kollam and beyond potentially influencing air quality through long-range transport of pollutants. The elevation is low, generally below 30 meters above sea level, which can exacerbate the trapping of pollutants, particularly during periods of stagnant air. The prevailing winds, influenced by the monsoon patterns and coastal geography, are a key factor in dispersing or concentrating airborne particles. The region's dense vegetation, while beneficial for carbon sequestration, can also contribute to biogenic volatile organic compounds (BVOCs), impacting ozone formation.

Kaduturutti’s tropical climate dictates a distinct wet and dry season cycle, profoundly impacting its air quality profile. The southwest monsoon, typically spanning from June to September, brings torrential rainfall and strong winds, effectively flushing the atmosphere of accumulated pollutants. This period generally sees the best air quality, with frequent rain showers acting as a natural cleansing mechanism. However, the onset of the monsoon can initially bring increased dust and particulate matter due to wind-blown soil. The dry season, from October to May, presents a different challenge. Reduced rainfall and lower wind speeds lead to a build-up of pollutants. Temperature inversions, common during the cooler months (December-February), trap pollutants near the ground, potentially worsening air quality. Fog, frequently occurring during these months due to the proximity to Ashtamudi Lake and high humidity, further restricts atmospheric mixing and concentrates pollutants. March and April often experience elevated levels of dust and smoke from agricultural burning practices in surrounding areas, preparing fields for the next planting season. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during periods of fog or temperature inversions. Outdoor activities are generally best enjoyed during the monsoon months, although awareness of initial dust surges is advised. The humid climate throughout the year can exacerbate respiratory issues, so maintaining hydration and avoiding prolonged exposure to potential irritants is always recommended.
