The biological action of xylol isomers as ambient air pollutants was investigated. The maximum single allowable concentrations of orthoxylol (0.3 mg/m3), methaxylol (0.24 mg/m3), papaxylol (0.27 mg/m3) were determined by measuring the odour thresholds of the substances in 122 volunteers. The average daily allowable concentrations of the xylol isomers were found to be 0.4, 0.16, and 0.96 mg/m3, respectively.
