      <subfield code="a">Levels of airborne dust have been measured in the breathing zone of five warehouse packers in a carbon black manufacturing plant on consecutive days over 1 week. Post-shift urine samples were collected on individuals over the week and the concentration of the pyrene metabolite 1-hydroxypyrene have been measured. A questionnaire was used to assess the likelihood of potential confounding factors, such as direct exposure to feedstock oil, as well as smoking and diet. The results suggest that 1-hydroxypyrene may be a useful indicator of exposure to the PNAs adsorbed onto carbon black</subfield>
