Diesel exhaust and cancer risk in the M5 tunnel

Although prolonged occupational exposure to diesel exhaust as might be experienced, for example in the mining industry, is a cause of cancer in humans, there is no evidence to suggest that potential intermittent exposure to diesel exhaust as experienced by commuters in the M5 tunnel poses an increased risk for lung cancer.  Monitoring of air quality in the M5 tunnel as conducted by the NSW Roads and Traffic Authority indicates that air quality complies with Australian Air Quality Standards.
