Tāran, a small town in the Muzaffarpur district of Bihar, India, sits at coordinates 26.1570°N, 87.5430°E. The landscape is characteristic of the Indo-Gangetic Plain – a flat, fertile alluvial plain formed by the sediment deposition of the Ganges and its tributaries. This region is predominantly agricultural, with rice paddies and wheat fields dominating the surrounding terrain. Tāran’s elevation is relatively low, contributing to limited atmospheric dispersion of pollutants. The Burhi Gandak river flows nearby, influencing local humidity and potentially contributing to localised fog formation during cooler months. While not a major industrial hub itself, Tāran is situated within a region experiencing increasing industrial activity in Muzaffarpur and surrounding areas, leading to regional pollution transport. The urban-rural gradient is sharp; Tāran is a relatively small settlement surrounded by intensely farmed land. This proximity to agricultural practices introduces sources of particulate matter from crop residue burning and fertiliser application. The flat topography and limited natural barriers hinder the flushing out of pollutants, exacerbating air quality challenges. Dust from unpaved roads and construction activities further contribute to particulate matter concentrations, particularly during the dry season. The town’s location within the densely populated Bihar plain means it’s susceptible to regional air pollution events.

Tāran experiences a distinct seasonal air quality pattern dictated by the monsoon and post-monsoon climate. The monsoon season (June-September) generally brings improved air quality due to rainfall washing away pollutants and suppressing dust. However, increased humidity can also foster mould growth, impacting respiratory health. October-November sees a deterioration as the monsoon retreats, and agricultural burning of crop residue intensifies following the harvest. This period often experiences stagnant air conditions and temperature inversions, trapping pollutants near the ground. Winter (December-February) is typically the worst period for air quality, with low temperatures, calm winds, and frequent fog exacerbating pollution levels. Smoke from household cooking using biomass fuels adds significantly to particulate matter. March-May brings rising temperatures and increasing dust storms, contributing to higher particulate matter concentrations. These months are particularly challenging for individuals with respiratory conditions. Sensitive groups – children, the elderly, and those with pre-existing lung or heart conditions – should limit outdoor activity during the winter and pre-monsoon seasons. Monitoring local weather patterns and avoiding peak pollution times is crucial for protecting health.
