i*u" 1 * A new essay procedure was developed for the detection of methylthfo compounds in urine. The method is based on alkaline hydrolysis of y urine samples and subsequent gas chromatographic determination of methyl mercaptan in the headspace of acidified hydrolysates. By f application of this method a greatly increased oxcrotion of a i mothylthio compound in the urine of CH3Cl-exposed workers was shown. The compound was identified as S-msthylcystoino. A study of the f urinary S-methylcysteino excretion in a group of workers during a seven-day shift revealed that 2 of 6 workers hardly excreted any S-methylcysteine after exposure to methyl chloride. i ^'Plastic lung'.
