Nāngloi Jāt, a rapidly urbanising locality in West Delhi, India, sits at coordinates 28.6833°N, 77.0667°E. The area is characterised by a relatively flat, alluvial plain typical of the Indo-Gangetic Plain, with an elevation of approximately 216 meters. This low-lying terrain contributes to the trapping of pollutants, particularly during winter months. Historically, Nāngloi Jāt was a rural village, but decades of migration and expansion from central Delhi have transformed it into a densely populated residential and industrial area. It’s situated within the National Capital Territory of Delhi, benefiting from, and contributing to, the region’s complex urban network. Surrounding Nāngloi Jāt are extensive agricultural lands transitioning into urban sprawl, alongside pockets of small-scale industries. The proximity to the Yamuna River, while providing some moisture, doesn’t offer significant dispersion of pollutants due to prevailing wind patterns. The urban-rural gradient is steep, with a marked increase in pollution levels as one moves closer to the built-up areas. The area’s location downwind of major industrial zones and transportation corridors exacerbates air quality challenges. Dust from construction and unpaved roads further compounds the problem, creating a complex pollution profile.

Nāngloi Jāt experiences a distinct seasonal air quality pattern. October to February represents the most challenging period. Cooler temperatures lead to temperature inversions, trapping pollutants near the ground. Weak winds and frequent foggy conditions further hinder dispersion. November and December are particularly problematic due to post-harvest crop burning in surrounding agricultural areas, adding significant particulate matter to the atmosphere. The monsoon season, from July to September, offers temporary relief. Heavy rainfall effectively washes away pollutants, resulting in cleaner air. However, increased humidity can also promote the formation of secondary pollutants. March to June sees a gradual increase in temperatures and wind speeds, improving air quality, though dust storms are common in May and June, temporarily elevating particulate matter. Sensitive groups – children, the elderly, and those with respiratory conditions – should avoid prolonged outdoor activity during the winter months and periods of high dust. During the monsoon, precautions against waterborne diseases are crucial. The transition months of March-April and September-October require vigilance as pollution levels fluctuate.
