ABSTRACT
Because there are very few air quality monitoring sites and it is arduous to select opportune analytical tools, the augmentation of ambient atmospheric particle transmission to the pollution load is difficult to estimate. Therefore, using SEM -EDX and source apportionment through National Oceanic and Atmospheric Administration- Hybrid Single-Particle Lagrangian Integrated Trajectory (NOAA HYSPLIT) Model, the evaluation of the sources of elements tied to particulate matter through the application of physicochemical signatures in Srinagar Garhwal was investigated in order to stay up to date on information regarding air quality. Si was found in higher proportion in the particles than other elements that EDX measured. SEM morphological data indicated that the most common inhalable particles were irregularly shaped mineral particles and aluminosilicate. The research suggests adequate government regulation, industrial compliance, automobile emission control, public awareness campaigns, and seamless municipal solid waste incinerator operations can all greatly lower pollution from fine particulates.
