Abstract |
Methods of monitoring occupational exposure to methanol were investigated in volunteers with methanol ingestion. Urinary methanol concentrations accurately reflected those in the blood over a considerable range of concentrations. Urinary formic acid concentration (in µg/ml) was too variable but rate of urinary excretion of formic acid (in µg/min) did reflect methanol uptake. The ratio of urinary formic acid to creatinine concentrations is a practical monitoring method. However formic acid elimination rate is reduced by ingestion of alcoholic beverages. Urinary methanol concentration is favoured as a method of monitoring, and a concentration of 10µg/ml measured at the end of the work shift is suggested as the limit above which occupational exposure should be suspected and the appropriate action taken. |
