Rapid and cost-effective presumptive screening of firearm discharge-consistent metals via bromopyrogallol red colorimetry and machine learning.

The identification of gunshot residues (GSR) is pivotal in forensic chemistry; however, standard confirmatory techniques, such as Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM/EDS), are often costly, time-consuming, and centralized in major urban facilities. This study proposes a rapid and...
