Forensic utility of a nitrogen and oxygen isotope ratio time series of ammonium nitrate and its isolated ions.

Abstract

Ammonium nitrate (AN) based fertilizers are inexpensive and easily obtained, characteristics that often lead to their use in homemade explosive devices. The stable nitrogen and oxygen isotope ratios (15N/14N and 18O/16O, expressed as δ15N and δ18O) of AN have the potential to aid in forensic investigations by providing supplemental properties for sample-to… (More)
