Contaminated disposable rubber gloves as evidence samples after a chemical attack with nerve agents

Original language description

Nerve agents have been used recently in the Syrian civil war. Collecting relevant samples for retrospective identification of an attack is often problematic. The article deals with the possibility of using contaminated gloves as an analytical sample for evidence of the chemical weapons use. There have not yet been published studies dealing with the identification of chemical warfare agents in this type of matrix, where the diversity of chemical properties of gloves and the lifetime of the contaminated sample would be considered. Sarin, soman, and cyclosarin were used as contaminants in the study. Nitrile, latex, and vinyl disposable gloves were chosen as matrices. The identification method was gas chromatography. Six solvents commonly used in military laboratories were tested as extractants. The extraction procedure was optimized in terms of the appropriate method (vortex) and the required extraction time (1 min) and resulted in significant reduction in sample preparation time. The chromatographic background of the extracts was also monitored in order to find a method with the least number of peaks interfering in the identification. Suitable solvents were hexane and acetonitrile. The lifetime of the sample was also investigated. The worst result was recorded for latex. For individual contaminants, the time varied depending on the volatility. The developed procedures were successfully validated within a sample handling effects scenario. The results demonstrate that in the event of an ongoing military risk at the site of an attack, even discarded disposable rubber glove type samples can be used as evidence.
