Nandigaon, a small town in Andhra Pradesh, India (17.1190°N, 78.2564°E), is situated within the Krishna River delta region. The terrain is predominantly flat, characteristic of alluvial plains formed by the river’s deposition over millennia. This low-lying landscape, with an elevation generally below 50 meters, influences air quality by limiting natural dispersion of pollutants. Nandigaon is surrounded by intensely cultivated agricultural land, primarily paddy fields, which, while vital for the local economy, contribute to seasonal biomass burning after harvest, releasing particulate matter. The town’s position isn’t directly adjacent to major industrial belts, but regional industrial activity in nearby districts like Nalgonda and Hyderabad does exert an indirect influence via regional transport of pollutants. The urban-rural gradient is sharp; Nandigaon itself is relatively small with a population of 16,752, quickly transitioning to rural agricultural landscapes. The Krishna River, though a source of irrigation, also contributes to humidity, potentially exacerbating secondary pollutant formation. Local brick kilns and small-scale industries, common in the region, are likely point sources of pollution. Wind patterns, largely dictated by the seasonal monsoon, play a crucial role in pollutant dispersal, or lack thereof, depending on prevailing conditions.

Nandigaon’s air quality follows a distinct seasonal pattern. The post-monsoon period (October-November) often sees a temporary improvement as rainfall washes away accumulated pollutants, but this is short-lived. Winter (December-February) brings cooler temperatures and increased temperature inversions, trapping pollutants near the ground, leading to poorer air quality. This is compounded by increased biomass burning in agricultural fields after the harvest. The pre-monsoon months (March-May) are typically the worst, with high temperatures, low wind speeds, and dust storms contributing to elevated particulate matter levels. The onset of the southwest monsoon (June-September) provides significant relief, as heavy rainfall effectively scrubs the atmosphere. However, increased humidity can also promote the formation of secondary pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the pre-monsoon and winter months. March, April, and January are particularly challenging. During the monsoon, while air is cleaner, the damp conditions can exacerbate fungal growth, potentially triggering respiratory issues. Monitoring local weather patterns and avoiding peak pollution times is crucial for maintaining health.
