Kukraun, a small town in the Bihar plains of India (25.6858°N, 87.1638°E), is situated within a largely flat, alluvial landscape. The town’s elevation is relatively low, typical of the Gangetic Plain, contributing to limited atmospheric dispersion of pollutants. Kukraun lies within the Muzaffarpur district, an area heavily reliant on agriculture, particularly rice and sugarcane cultivation. This agricultural activity, while vital to the local economy, introduces particulate matter from crop residue burning and fertilizer use. The surrounding terrain is predominantly farmland, interspersed with small settlements, creating a gradual urban-rural gradient. The Burhi Gandak river flows nearby, but its influence on local air quality is more related to humidity and potential for stagnant air masses than direct pollutant transport. While Kukraun isn’t a major industrial hub, regional industrial activity in Muzaffarpur and nearby areas contributes to background pollution levels. The town’s location within the Indo-Gangetic Plain, a known hotspot for air pollution, means it’s susceptible to the accumulation of pollutants, especially during winter months when meteorological conditions hinder dispersion. The lack of significant topographical features – hills or mountains – further exacerbates this issue, limiting natural ventilation. The density of population, though relatively low at 17,276, is increasing, adding to localised emissions from domestic sources.

Kukraun’s air quality follows a distinct seasonal pattern. The post-monsoon period, from October to November, sees a significant deterioration in air quality. The burning of crop residue after the harvest, combined with cooler temperatures and the onset of temperature inversions, traps pollutants near the ground. This is typically the most challenging time for respiratory health. December and January bring consistently poor air quality, with fog exacerbating particulate matter concentrations. February and March offer a gradual improvement as temperatures rise and wind speeds increase, dispersing pollutants. The pre-monsoon months, April and May, are characterised by dust storms and high temperatures, leading to increased levels of coarse particulate matter. The monsoon season, from June to September, generally provides the cleanest air, as rainfall washes away pollutants and increased humidity suppresses dust. However, increased cloud cover can also lead to stagnant air. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit outdoor activity during October-January and take precautions during April-May. Monitoring local conditions and heeding health advisories is crucial. Avoiding peak traffic hours and using masks when outdoors during polluted periods are recommended.
