Tentative criteria for assessing workers exposure to toluene by urinary toluene screening.
This study assessed screening thresholds for determining workers exposure to toluene (Tol) by urinary Tol (Tol-U) and proposed applicable criteria for on-site settings. Participants' urine samples (n = 21) were collected at the end of the workday during the latter half of a week and the Tol-U concentration was assayed. Simultaneously, each worker's exposure dose to Tol in the breathing zone dur...
متن کاملEvaluation of Toluene Exposure in Workers at Industrial Area of Sidoarjo, Indonesia by Measurement of Urinary Hippuric Acid
Background: Toluene is a harmful substance still being used as a solvent and catalyst in many industries that can increase the level of urinary hippuric acid (UHA). This study was designed to examine the level of toluene and UHA among workers of industrial site in seven companies in Sidoarjo, Indonesia and to analyze the risk factors for abnormal UHA. Methods: This study was an analytical cross...
متن کاملToxicokinetics of toluene and urinary excretion of hippuric acid after human exposure to 2H8-toluene.
Nine male volunteers were exposed to 2H8-toluene (200 mg/m3 for two hours during a workload of 50 W) via inspiratory air with the aid of a breathing valve and mouthpiece. Labelled toluene was used to differentiate between hippuric acid originating from exposure to toluene and hippuric acid normally excreted in urine. The total uptake of toluene was 2.2 (standard deviation (SD) 0.2) mmol, or 50%...
متن کاملRelationship between exposure to toluene and excretion of urinary metabolites in Korean female solvent workers.
Toluene is known to be the most popular solvent for industrial use,1,2) and attention has been paid on the possibility of biological monitoring of toluene exposure by urinalysis for metabolites such as hippuric acid and o-creso1.3-5) In a previous study6) on possible ethnic difference in toluene metabolism, it was disclosed that Chinese toluene workers excrete less hippuric acid in urine than t...
متن کاملUrinary hippuric acid concentration after occupational exposure to toluene.
The results of industrial investigations have shown a correlation between the rate of hippuric acid excretion in a single urine sample collected after daily occupational exposure and the amount of toluene absorbed. The rate of hippuric acid excretion and the average concentration of toluene vapour during exposure time were also related. The quantitative range of the test has been limited to amo...
