The partially unburned GSR compounds contain elements that are ready to explode in appropriate circumstances. This can lead to serious safety problems, especially in indoor shooting ranges. In this study, the GSR compounds collected from Machine Chemistry Institute brand 9×19 mm parabellum shells were analyzed using gas chromatography/mass spectrometry (GC-MS) method. As a result of the analysis, nitroglycerin, dimethyl phthalate, 2,4-dinitrotoluene, diphenylamine, n-diphenylamine, trimethyl, 2,4-methypropyl and dibutyl phthalate compounds were detected in the GSR compounds. The changes in the amounts of these compounds depending on the number of shots wire were discussed.
