Dholka, a city in Gujarat, India, sits at coordinates 22.7200°N, 72.4700°E, within the broader Indo-Gangetic Plain. Its terrain is largely flat, characteristic of the region, with an elevation averaging around 75 meters above sea level. This low-lying geography contributes to potential air stagnation. The city’s location within the Gulf of Khambhat coastal plain influences its climate, bringing moderate humidity. Dholka is surrounded by intensely cultivated agricultural land, primarily cotton, wheat, and groundnuts, with increasing mechanisation. While not a major industrial hub itself, Dholka is within reach of larger industrial zones around Ahmedabad, approximately 40km to the east, and the petrochemical complexes along the coast. This proximity means it can experience transboundary pollution. The urban-rural gradient is pronounced; the city core is densely populated, transitioning rapidly to agricultural fields. Dust from agricultural practices, particularly during harvest seasons, is a significant local contributor to particulate matter. The lack of substantial natural barriers to wind flow means pollutants can disperse, but also accumulate during stable atmospheric conditions. The city’s growth, driven by textile and agricultural processing, is increasing vehicle emissions and construction dust, further impacting local air quality.

Dholka’s air quality follows a distinct seasonal pattern. The post-monsoon months (October-November) often see a temporary improvement as rainfall washes away pollutants, but this is short-lived. Winter (December-February) brings the most challenging conditions. Lower temperatures create temperature inversions, trapping pollutants near the ground, and reduced wind speeds hinder dispersion. Smoke from agricultural burning, combined with domestic fuel combustion, significantly degrades air quality during these months. March-May sees a gradual worsening as temperatures rise and dust storms become frequent, increasing particulate matter. The pre-monsoon period is characterised by hot, dry winds carrying dust and pollutants. The monsoon season (June-September) provides the most substantial relief. Heavy rainfall effectively scrubs the air, reducing particulate matter and other pollutants. However, increased humidity can promote the formation of secondary pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during winter and pre-monsoon periods. Monitoring local conditions and using appropriate respiratory protection is advisable. Avoiding peak traffic hours can also reduce exposure.
