Gunshot residue preservation in seawater

Highlights • We compare shot ribs in three marine settings that differ in their ambient habitat. • We expected changes and differences of gunshot residue identification over time. • Gunshot residue was lost faster upon exposure to seawater. • Gunshot residue could still be detected after 38 days exp...

Zusammenfassung:	Highlights • We compare shot ribs in three marine settings that differ in their ambient habitat. • We expected changes and differences of gunshot residue identification over time. • Gunshot residue was lost faster upon exposure to seawater. • Gunshot residue could still be detected after 38 days exposure to seawater. • Difference between analysed specimens per habitat disappeared upon defleshing.
