Kodāngipatti, a small town in Tamil Nadu, India (9.9920°N, 77.4332°E), is situated within the fertile plains of the state’s central region. The town’s elevation is relatively low, contributing to limited natural dispersion of pollutants. It lies within the Cauvery River basin, though not directly on the river itself, benefitting from the agricultural productivity the river supports, but also potentially experiencing impacts from agricultural runoff and associated practices. The surrounding landscape is predominantly agricultural, characterized by paddy fields, coconut groves, and interspersed rural settlements. Kodāngipatti is not a major industrial hub, but its proximity to larger towns and cities with industrial activity – particularly those along the major transportation corridors – means it can experience pollutant transport. The urban-rural gradient is quite sharp; Kodāngipatti itself is a relatively compact settlement, quickly giving way to agricultural land. This proximity to agricultural activities introduces potential sources of particulate matter from dust and biomass burning. The local terrain is generally flat, hindering the flushing of pollutants by wind. The town’s location, while benefiting from agricultural prosperity, presents challenges for maintaining optimal air quality due to limited dispersion and potential pollutant sources from surrounding areas and regional transport.

Kodāngipatti experiences a tropical climate with distinct wet and dry seasons, heavily influencing its air quality. The dry season, roughly from February to May, sees a build-up of particulate matter due to increased dust from agricultural activities and potential biomass burning for land preparation. Temperatures rise during this period, exacerbating the issue through increased photochemical reactions forming ground-level ozone. March and April are typically the worst months for outdoor activity for those with respiratory sensitivities. The arrival of the southwest monsoon in June brings relief, washing away pollutants and improving air quality significantly. However, increased humidity can also promote mold growth, impacting those with allergies. September and October, following the monsoon’s retreat, can see a resurgence of stagnant air and localized pollution. November to January offers the most favourable air quality, with cooler temperatures, occasional rainfall, and moderate winds aiding dispersion. During the monsoon, while air is cleaner, increased dampness can trigger respiratory issues. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit outdoor exposure during peak pollution periods and monitor their health closely.
