Abstract: Occupational exposure biological monitoring techniques were applied for the diagnosis of inhalation abuse and evaluation levels to benzene, toluene, ethylbenzene, xylenes, n ‐hexane, in 44 Tunisian adolescents children suspected volatile substance addiction. Urinary trans,trans ‐muconic acid, hippuric acid (HA), mandelic methylhippuric acids determinations performed by high performance liquid chromatography with a photodiode array detector, urinary o ‐cresol ( ‐Cr) 2,5‐hexanedione...
The aim of this study was to assess the exposure Toluene in paint industry and evaluate environmental biological monitoring techniques for assessment occupational aromatic hydrocarbon. In study, personal active passive air sampling toluene measurements, blood urine respectively B-Tol HA or U-Tol analyses eight workers from two thinner production factories were collected during four successive working days. Correlations analyzed between indicators levels. concentration measured samples ranged...
We wish to determine the urinary trans,trans-muconic acid reference values in Tunisian general population, and evaluate impact of several factors (age, gender, tobacco...) on these values. Urine samples were collected from 182 healthy subjects who had not been occupationally exposed benzene. This determination was performed by solid phase extraction sampling technique together with high performance liquid chromatography-photodiode array detector. Trans,trans-muconic ranged 0.003 0.618 mg/g...
Abstract A simple, sensitive, and reproducible high performance liquid chromatographic procedure is described for the simultaneous determination of urinary metabolites several aromatic hydrocarbons: mandelic phenylglyoxylic acids from ethylbenzene; hippuric acid toluene, methylhippuric xylenes. The employed mobile phase conditions allowed relatively low detection limits (0.1 to 0.2 mg/L). method was tested on 33 workers in paint industry nonoccupationally exposed Tunisian subjects....
