Eravattūr, a small town in Kerala, India, is situated at coordinates 11.5833°N, 75.7333°E, nestled within the coastal plains of the Malabar region. With a population of approximately 15,716, the town’s geography is defined by its relatively low elevation and proximity to the Arabian Sea, roughly 15-20 kilometers distant. The terrain is largely flat, characteristic of the Kerala coastal belt, interspersed with backwaters and paddy fields. This landscape significantly influences local air quality. The surrounding areas are predominantly agricultural, with coconut plantations, rice paddies, and spice farms dominating the rural landscape. While Eravattūr itself isn’t a major industrial hub, its position within the larger Kozhikode district means it’s susceptible to regional pollution transport from nearby industrial areas and transportation corridors. The urban-rural gradient is fairly sharp, transitioning quickly from densely populated areas to agricultural land. The coastal breezes offer some natural ventilation, but can also carry pollutants from marine sources and potentially trap them during periods of calm. The dense vegetation provides some natural filtration, but its capacity is limited by the scale of potential pollution sources. The backwaters, while ecologically important, can also contribute to localised humidity and potentially trap pollutants, especially during stagnant weather conditions.

Eravattūr experiences a tropical climate, with distinct wet and dry seasons heavily influencing air quality. The southwest monsoon, typically arriving in June and lasting until September, brings heavy rainfall which effectively washes particulate matter from the air, resulting in generally improved air quality during these months. However, increased humidity can also foster mould growth, impacting respiratory health. October to February constitutes the drier season, marked by lower rainfall and calmer winds. This period often sees a build-up of pollutants, particularly dust and vehicle emissions, as there’s less atmospheric cleansing. January and February are often the least favourable months for outdoor activity for those with respiratory sensitivities. March to May is the hottest and most uncomfortable period, with increased potential for ground-level ozone formation due to higher temperatures and sunlight. Temperature inversions, where a layer of warm air traps cooler air below, can exacerbate pollution during these months. Fog is infrequent but can occur during the transition periods, trapping pollutants near the ground. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit strenuous outdoor activity during the dry season and monitor their health closely.
