Nine healthy male volunteers were exposed to m-xylene for four hours a day, three hours in the morning and one hour in the afternoon, with a 40 minute break in between, at six day intervals during six succeeding weeks to explore the effects of m-xylene on the sense of balance. The atmospheric m-xylene concentrations were either fixed at 8.2 mumol/l (200 ppm) or they fluctuated (5.2-16.4 mumol/l...

Self-assembly of a range of carboxylic acids (benzoic acid, dinicotinic acid, nicotinic acid, and isophthalic acid) with the europium complex of 5-nitro-α,α'-bis(DO3Ayl)-m-xylene (where DO3A is 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid) has been explored to establish the thermodynamics of binding in a range of solvent systems and in a range of aqueous buffer solutions. In this system,...

Effects of combined exposure to toluene and m-xylene in the conditions of subchronic inhalation experiments in rats were examined. Rats were exposed to vapours of individual solvents and their 1:1 mixture at concentrations of 1000 ppm or 100 ppm, 6 h/day, 5 days/week, for 3 or 6 months, respectively. In rats exposed for 3 or 6 months to toluene, m-xylene and their mixtures (1:1) at concentratio...

The separation of hippuric and m-methylhippuric acid as toluene and m-xylene metabolites present in urine of people exposed simultaneously to toluene and xylene is described. Chloroform was used for hippuric and m-methylhippuric acid extraction. Satisfactory separation of these metabolites was obtained on TLC plates covered with silica gels and developed in chloroform acetic acid-water (4:1:1);...

Ogata, M., Takatsuka, Y., and Tomokuni, K. (1971). Brit. J. industr. Med., 28, 382-385. Excretion of hippuric acid and mor p-methylhippuric acid in the urine of persons exposed to vapours of toluene and mor p-xylene in an exposure chamber and in workshops, with specific reference to repeated exposures. Four male volunteers were exposed to 200 p.p.m. of toluene for five one-hour periods separate...
