Abstract

The research aimed to investigate the nitrate and nitrite content in gunshot residue on various fabrics, comparing their concentrations. The researcher utilized the UV-visible spectroscopy technique to analyze the residues left on different fabric types (cotton, rayon, and satin) after shooting with a Smith & Wesson revolver .38 Special, copper-clad lead type (Full Metal Jacket) fired at a distance of 80 centimeters. Sampling was conducted at different intervals: 1 day, 1 week, 2 weeks, and 1 month. Quantitative analysis of the gunshot residue revealed the concentrations of nitrate and nitrite, it was found that there was a statistically significant difference at the 0.05 level of different conditions on the fabric, fabrics, and the different periods on the fabric were statistically significant at the 0.05 level.
