      <subfield code="a">Phenol is a normal constitutent of human urine and concentrations above the physiological level have been found in the urine of people that have contact with benzene or phenol. The investigation was carried out on 106 male workers employed in the distillation of the high temperature phenolic fraction of tar and exposed mainly to phenol, cresols, xylenols, and other phenolic derivatives. Control urine specimens were collected from 26 male subjects not exposed professionally to phenol, cresols, or xylenols. All men were smokers</subfield>
