Nowadays, laboratory forensic examinations are based on elaborated and verified protocols, allowing for quite precise identification of the type of explosive used in post blast residues. Non-degraded explosives persist in trace quantities mainly on the broken components of explosive devices. Due to this, special care must be taken in order to prevent destruction of minute quantities of explosive material during examination. Apparently quite a big problem is caused by components of electrical cells being the source of reactive chemical compounds that affect the level of identified traces of explosives. The present paper describes the influence of substances present in alkaline batteries cells and Leclanché cells on the decomposition of trace amounts of TNT. Reaction of TNT with battery components was conducted in solution at room as well as the temperature of boiling methanol. Quantitative analysis of the decrease in TNT levels in methanol extracts was carried out by means of GC/MS.
