Edattala, nestled in Thrissur district, Kerala, India, occupies a geographically significant position within the state’s verdant landscape. Located at approximately 9.8678° N latitude and 76.4361° E longitude, the village sits on the fringes of the Chalakudy River, a major tributary of the Periyar River, influencing local humidity and microclimates. The terrain is predominantly undulating, characteristic of Kerala’s Western Ghats foothills, with elevations ranging from roughly 20 to 60 meters above sea level. This gentle slope facilitates drainage but can also contribute to localized fog formation, particularly during cooler months. Edattala’s surrounding landscape is a mosaic of rice paddies, coconut groves, and small-scale agricultural plots, typical of Kerala’s rural character. The urban–rural gradient is relatively sharp; Edattala itself is a small village, transitioning quickly into agricultural land, with Thrissur city, a significant urban center, lying approximately 25 kilometers to the east. While Edattala doesn't sit directly within a major industrial belt, its proximity to Thrissur and the broader Kochi metropolitan area means it is susceptible to pollutants transported via prevailing winds. The Chalakudy River, while a vital water source, can also act as a conduit for pollutants from upstream agricultural runoff and occasional industrial discharge. The region's tropical climate, with high temperatures and humidity year-round, influences atmospheric stability and pollutant dispersion, often leading to stagnant air conditions during certain periods.

Edattala’s air quality is intrinsically linked to Kerala’s distinct wet and dry seasons. The southwest monsoon, typically spanning June to September, brings torrential rainfall and strong winds, effectively flushing the atmosphere of accumulated pollutants. This period generally offers the best air quality, with frequent rain showers acting as a natural cleansing mechanism. However, the monsoon can also introduce particulate matter from soil erosion and agricultural activities. The subsequent dry season, from October to May, presents a different challenge. Reduced rainfall and calmer winds lead to a build-up of pollutants, particularly during the cooler months of December and January. Temperature inversions, where cooler air becomes trapped beneath a layer of warmer air, are more frequent during this period, hindering vertical mixing and concentrating pollutants near the ground. Fog, common during these months, further exacerbates the issue by trapping particulate matter. Agricultural burning, a practice sometimes employed to clear fields after harvest, can also contribute to localized spikes in pollution during the dry season. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during these months, limiting outdoor activity during periods of heavy fog or noticeable air stagnation. The transitional months of March and April see a gradual improvement in air quality as temperatures rise and winds pick up, signaling the approaching monsoon. Overall, the monsoon months offer respite, while the dry, cooler months require heightened awareness and preventative measures.
