Reota, a small town in the Gaya district of Bihar, India, occupies a relatively flat section of the Indo-Gangetic Plain at approximately 118 meters above sea level (coordinates 25.8194, 86.3061). This positioning within the plains significantly influences its air quality. The surrounding landscape is predominantly agricultural, characterized by intensive farming of rice, wheat, and pulses. The Phalgu River, a tributary of the Ganges, flows nearby, but its influence on local air circulation is limited due to the flat terrain. Reota’s location isn’t directly within a major industrial belt, however, the broader Gaya district experiences industrial activity related to stone crushing and brick kilns, contributing to regional particulate matter pollution. The urban-rural gradient is pronounced; Reota itself is a relatively small settlement, but is increasingly connected to larger urban centres like Gaya city. This connectivity brings increased vehicular traffic. Dust from unpaved roads and agricultural practices are significant local sources of pollution. The lack of substantial topographical features hinders natural dispersion of pollutants, leading to localized build-up, particularly during periods of calm weather. The climate is subtropical monsoon, with hot summers and cool winters, impacting pollutant behaviour.

Reota’s air quality follows a distinct seasonal pattern. The post-monsoon period (October-November) often sees the worst conditions. Reduced rainfall means dust and agricultural residue remain airborne, while cooler temperatures create temperature inversions, trapping pollutants near the ground. This is exacerbated by the burning of crop residue after the harvest. Winter (December-February) maintains poor air quality, with stagnant air and continued use of biomass for heating. The pre-monsoon months (March-May) bring increasing heat and dust storms, elevating particulate matter levels. The monsoon season (June-September) offers a temporary respite. Heavy rainfall effectively washes pollutants from the air, and increased humidity promotes settling of dust. However, increased cloud cover can also contribute to localized humidity-related pollution. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during October-February. March and April are also periods of concern. Monitoring wind direction is crucial; winds from the west can carry pollutants from larger industrial areas. Staying indoors during peak pollution times and using air purifiers are recommended.
