Tangutūru, nestled in the Krishna district of Andhra Pradesh, India, occupies a relatively flat coastal plain at approximately 15.35°N, 80.05°E. The city’s geography is fundamentally shaped by its proximity to the Bay of Bengal, roughly 20km east, influencing humidity and weather patterns. The terrain is predominantly alluvial, formed by the Krishna River delta, making the land fertile and supporting significant agricultural activity, primarily paddy cultivation. Tangutūru isn’t a sprawling metropolis; its urban character is more akin to a large town, exhibiting a gradient from denser core areas to surrounding rural farmland. This urban-rural interface is crucial for air quality, as agricultural practices like crop residue burning contribute to localised pollution. The region is not heavily industrialised compared to other parts of Andhra Pradesh, but the presence of small-scale industries, including food processing and brick kilns, adds to the emission sources. The coastal location means sea breezes can offer some dispersion, but during calmer periods, pollutants can accumulate. The surrounding landscape is characterised by rice paddies, coconut groves, and scattered vegetation, offering limited natural filtration of airborne particles. Understanding this interplay of geography and activity is vital for assessing and mitigating air quality challenges in Tangutūru.

Tangutūru experiences a tropical climate with distinct wet and dry seasons heavily influencing air quality. The dry season, from November to May, typically sees worsening conditions. Lower humidity and stagnant air allow particulate matter from agricultural sources, construction, and vehicular emissions to concentrate. January to March are often the most challenging months, with minimal rainfall to cleanse the atmosphere. Temperature inversions, common during cooler mornings, trap pollutants near ground level. The southwest monsoon, arriving in June, brings significant relief. Heavy rainfall effectively washes away pollutants, leading to substantially improved air quality throughout July, August, and September. However, increased humidity can also promote the formation of mould and secondary pollutants. The post-monsoon season (October-November) sees a gradual return to drier conditions and a corresponding increase in pollution. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the dry season, particularly in January-March. During the monsoon, while air is cleaner, precautions against waterborne diseases are essential. Fog, though infrequent, can exacerbate pollution during the cooler months.
