title: A rare fatal case of silicone resin precursor (SH792) poisoning.
abstract: A 39-year-old man committed suicide by ingesting a large quantity of SH792. SH792 is a silicone resin precursor used as a hardener for waterproof paints. It is polymerized in water; this process is then followed by the formation of silicone resin and the release of N,N-diethylhydroxylamine. In this decedent, analysis by infrared spectroscopy showed that polymerized silicone resin was present in the stomach contents. The amount of silica in his tissues was within levels seen in control subjects. N,N-diethylhydroxylamine was detected in the urine (0.7 microliters/ml) but not in the stomach contents. The data suggest that SH792 was polymerized in the stomach and the released N,N-diethylhydroxylamine (DEHA) was absorbed into the body. The mechanism of SH792 poisoning is also discussed.
