Srīkūrmam, nestled in the Alluri Sitharama Raju district of Andhra Pradesh, India, occupies a unique geographic position. Located at 18.2718°N, 84.0064°E, the town sits amidst the Eastern Ghats, a discontinuous range of mountains running parallel to the eastern coast of India. The terrain is predominantly hilly and forested, contributing to a relatively cooler climate compared to the coastal plains. Srīkūrmam’s elevation, though not exceptionally high, influences local wind patterns and contributes to the potential for temperature inversions, trapping pollutants. The town is situated relatively inland, away from direct coastal influences, but benefits from the moderating effects of the Bay of Bengal’s proximity. Surrounding Srīkūrmam are extensive agricultural lands, primarily cultivating rice and other food crops, alongside pockets of cashew and mango plantations. While not a major industrial hub itself, the region is increasingly experiencing industrial development, particularly related to food processing and mineral extraction, which contributes to localised emissions. The urban-rural gradient is pronounced, with Srīkūrmam serving as a market town for surrounding villages. This blend of agricultural activity, nascent industry, and hilly terrain creates a complex interplay of factors influencing air quality, making it susceptible to both regional and local pollution sources. The dense vegetation offers some natural filtration, but cannot fully mitigate the impact of increasing anthropogenic activities.

Srīkūrmam experiences a distinct wet and dry season, heavily influenced by the Indian monsoon. Air quality generally improves during the monsoon season (June-September) as rainfall effectively washes away particulate matter and suppresses dust. However, increased humidity can also foster mold growth, potentially impacting respiratory health. The post-monsoon period (October-November) sees a gradual deterioration in air quality as agricultural burning increases, preparing fields for the next crop cycle. This practice releases significant amounts of smoke and particulate matter. The dry season (December-May) presents the most challenging period for air quality. Lower wind speeds and frequent temperature inversions, particularly in the cooler months of December and January, trap pollutants near the ground. March and April, preceding the monsoon, are often the worst months, with high temperatures and dry conditions exacerbating dust and smoke from agricultural and potentially industrial sources. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit outdoor activity during these periods. During the monsoon, while air is cleaner, precautions against waterborne diseases are crucial. Overall, avoiding strenuous outdoor activity during the dry season and being mindful of agricultural burning periods is advisable.
