Yenkuvārigūdem, nestled in the Prakasam district of Andhra Pradesh, India, occupies a geographically significant position within the Krishna-Godavari plains. Located at approximately 17.2055° N latitude and 81.1598° E longitude, the city’s terrain is predominantly flat, characteristic of the fertile delta region. The surrounding landscape is a mosaic of agricultural fields, primarily cultivating rice and pulses, interspersed with pockets of scrubland and occasional rocky outcrops. The city’s proximity to the Bay of Bengal, roughly 80 kilometers to the east, influences local weather patterns and introduces a maritime element to the air, though the distance mitigates direct coastal pollution impacts. Yenkuvārigūdem sits at a relatively low elevation, averaging around 25 meters above sea level, which can exacerbate the trapping of pollutants, particularly during periods of atmospheric stability. The urban–rural gradient transitions rapidly, with agricultural activities dominating the immediate periphery. While Yenkuvārigūdem itself is a small town, it lies within a broader industrial belt extending along the national highway, connecting it to larger urban centers like Guntur and Vijayawada. This connectivity, while economically beneficial, also introduces the potential for transboundary pollution. The flat topography and prevailing wind patterns, often influenced by the monsoon, contribute to a relatively uniform distribution of pollutants across the town, though localized sources like agricultural burning and vehicular emissions create hotspots. The soil composition, largely alluvial, can also impact particulate matter suspension during dry periods.

Yenkuvārigūdem’s air quality follows a distinct seasonal pattern dictated by the region’s tropical climate and monsoon cycles. The pre-monsoon season (March-May) typically witnesses the poorest air quality. High temperatures and minimal rainfall create stable atmospheric conditions, frequently leading to temperature inversions where cooler air becomes trapped beneath a layer of warmer air, preventing pollutants from dispersing. Agricultural burning, a common practice for clearing fields after harvest, significantly contributes to particulate matter pollution during this period. The monsoon season (June-September) brings a dramatic improvement in air quality due to frequent rainfall, strong winds, and increased humidity, effectively washing away pollutants and dispersing them. October and November mark a transitional period, with gradually decreasing rainfall and increasing temperatures, potentially leading to a slight deterioration in air quality. The winter months (December-February) are generally the most pleasant, with cooler temperatures and moderate wind speeds, although fog can occasionally form, trapping pollutants near the ground. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon season, limiting outdoor activities during peak pollution hours. Agricultural workers are particularly vulnerable and should utilize appropriate respiratory protection. Maintaining indoor air quality through ventilation and air purification can also offer some relief. Awareness campaigns promoting responsible agricultural practices and reducing vehicular emissions are crucial for mitigating air pollution throughout the year.
