A fatal intoxication due to doxepin.

A fatal intoxication due to doxepin, a tricyclic antidepressant, is described. Concentrations of doxepin and its metabolite, desmethyldoxepin, were measured in blood, urine, myocardial, and other tissues using thin layer chromatography (TLC) and gas chromatography equipped with a flame-ionisation detector (GC/FID). The developed technique also permitted the quantitative determination of the cis and trans isomers of doxepin. A very remarkable concentration ratio of doxepin:desmethyldoxepin was observed in myocardial tissues. A detailed report on the possible significance is described.

Suicidal poisoning by nitrite.

The authors relate a suicidal poisoning by nitrites. Post mortem findings are reported as well as a method for the quantitative assessment of NO2- in blood, urine, gastric and intestinal contents, kidney and liver. The concentration values obtained are correlated with the methemoglobin figures which indeed are lethal. The highest concentrations of NO2- are found in the small intestine where the nitrites seem to resist chemical decomposition owing to the reducing properties of the bacterial flora.

Identification of volatile components in waste waters by combined head-space gas chromatography-mass spectrometry.

A method for the identification of volatile components in effluent waters is described. The sample is heated in a closed vessel at 80 degrees C and the head-space vapour injected in a gas chromatograph coupled to a mass spectrometer. Mass spectra are recorded every 4 seconds and stored by a Data Acquisition System. The reconstructed spectra enable very easy identification of the peaks of the chromatogram. The important contribution of the computer system to the sensitivity of the technique is demonstrated.

A double fatality with children due to fumigated wheat.

Two children, four and two years old, played on top of wheat, that had been fumigated with malathion, pyrethrum and phosphine. Both died within 18 hours. Because after the autopsy, death could not be attributed to any organic or violent cause, a toxicological analysis was carried out. No drugs, except alcohol, was detected. Those results were attributed to hydrolysis of malathion, yielding two molecules of ethanol. As this was an indirect proof of malathion ingestion, it was assumed that phosphine had been ingested as well and that consequently this was the cause of death, because it is much more toxic than malathion and because it was continuously generated from not completely dissolved aluminiumphosphide tablets, while the children were still playing.
