✦ Synopsis
Using oxtail soup as a simulated typical stomach contents, the detection of 32 non-drug poisons which had been individually added to the soup was achieved by the diffusion of the poisons either directly into a colour reagent, or indirectly by producing a detectable vapour by chemical action on the added poison. The diffusion was carried out at ambient temperature or at 100°C, using Cavett's micro-diffusion flasks, and included screening procedures for certain alcohols, aldehydes, ketones, ammonia, aromatic amines, benzene and homologues, cyanide, ethylene glycol, phenols and cresols, nitrobenzene and nitrophenol, trichloro-compounds, sulphur anions and sulphur dioxide, and volatile oxidative anions (chlorate, nitrate and nitrite). No previous treatment of the biological medium (e.g. maceration, extraction or dialysis) was necessary, and the minimum detectable level of each poison varied from 1-1.5 pl (benzene and homologues) to 50 mg (potassium bromate) per 5 ml aliquot of soup used for screening.
