The industrial solvents, toluene and xylene, have physicochemical properties that can be hazardous to the workers exposed. Since hippuric acid and m-methyl-hippuric acid represent the products of toluene and xylene biotransformation in urine, they are used as biological markers in
Determination of methylhippuric acid in human urine by high-performance liquid chromatography and by isotachophoresis.

Journal of chromatography, 573(2), 318-322 (1992-01-17)
A high-performance liquid chromatographic method is described for the simultaneous determination of six urinary metabolites of several aromatic chemicals: phenol (from benzene), hippuric acid (from toluene), 3-methylhippuric acid (from xylene), mandelic and phenylglyoxylic acid (from styrene) and 4-nitrophenol (from nitrobenzene).
M J Miller et al.
International archives of occupational and environmental health, 72(2), 89-97 (1999-04-10)
Solvent exposures commonly involve mixtures of substances or mixtures of isomers of a single solvent. These may be metabolised through common pathways, resulting in the potential for metabolic interactions. These may then lead to accumulation of solvent or metabolic intermediates
R Tardif et al.
Occupational and environmental medicine, 51(3), 187-191 (1994-03-01)
This study was undertaken to determine whether previous subacute treatment with ethanol could modify the kinetics of m-xylene in humans. A group of six volunteers was exposed twice to either 100 or 400 ppm of m-xylene during two hours (between
