Sažetak
Indicator tubes from a field kits for detection of organophosphorus compounds in the air were found on the territory of Croatia, in barracks liberated during the war years of 1991/1992, and were analysed during 1993/95. The detection kit consisted of glass indicator tubes with two sealed vials within each tube, a device for opening the tubes and breaking the vials, and an air sampling pump. The tubes were marked with serial numbers and expiry dates (1974-1992), but the description as to their contents was unavailable. The aim of this study was to identify the contents of the indicator tubes and to establish whether they were still suitable for the detection of organophosphorus compounds. One vial was found to contain a cholinesterase (EC 3.1.1.7) preparation, and the other vial contained a non-thiocholine substrate and a pH-sensitive indicator (most probably cresol red). Applying DDVP as an organophosphorus cholinesterase inhibitor, it was found that all sets of indicator tubes were suitable for use regardless of the indicated expiry dates. Furthermore, the same tubes were found suitable for detection of organophosphorus compounds in water.
