Markers of Exposure to Diesel Exhaust in Railroad Workers

Research Report 33,
1990

This report describes a study by Dr. Schenker and colleagues to investigate the usefulness of urinary mutagenicity as a biological marker of occupational diesel exhaust exposure. Personal exposure to diesel exhaust over 2 consecutive work shifts was monitored via personal air samplers in 87 railroad workers, with adjustment for first-hand and environmental tobacco smoke exposure. Urine samples collected at the end of shifts were evaluated for mutagenicity and analyzed for any correlation with diesel exhaust exposure.
