Abstract
Introduction: Introduction: Air pollution is a significant environmental
challenge globally, exacerbated by industrialization and increasing vehicular
emissions. This study focuses on Jaipur, India, where rapid urbanization and
industrial growth have intensified pollution levels, impacting public health
and environmental quality.
Materials and methods: This study utilized secondary data from the
Rajasthan State Pollution Control Board and satellite imagery obtained
from the NRSC BHUVAN. Geographic Information System (GIS) tools
were employed to analyze pollution data from six sample sites in Jaipur.
Interpolation techniques, including Kriging and Inverse Distance Weighting
(IDW), were used to map the spatial distribution of pollutants.
Results: From 2011 to 2019, Jaipur experienced varying levels of air pollution,
with high concentrations of Particulate Matter (PM10
), Sulfur dioxide (SO₂),
and Nitrogen dioxide (NO₂) observed in industrial and commercial zones,
such as the Vishwakarma Industrial Area and Ajmeri Gate. Areas with natural
features, like Jhalana Dungri and the Malaviya Industrial Area, consistently
showed lower pollution levels.
Conclusion: The study highlights significant spatial and temporal variations
in air quality across Jaipur, influenced by industrial activities and vehicular
emissions. Effective pollution control measures and urban planning strategies
are essential to mitigate the adverse impacts of air pollution on public health
and environmental sustainability in Jaipur and similar urban centers
