Exposure to diesel exhaust can cause lung cancer

Diesel exhaust causes lung cancer and may also causes bladder cancer, according to experts.

Following a meeting of the World Health Organisation’s International Agency for Research on Cancer (IARC), the exhaust from diesel engines has been reclassified as carcinogenic. Previously recognised as probably carcinogenic, a review of epidemiological and toxicological studies by a panel of leading scientists has now established that sufficient evidence exists to list diesel exhaust as a group 1 carcinogen.

The IARC panel found that there was sufficient evidence to conclude that diesel exhaust is a cause of lung cancer. The panel also found that there is some limited evidence of link between exposure to diesel exhaust and bladder cancer.

Diesel exhaust causes an inflammation in the lungs which over time may develop into lung cancer. Railway workers, mechanics, lorry drivers, miners, workers operating heavy machinery and workers engaged in shipping are amongst the most vulnerable groups.

Brian Terry, senior safety rep for the GMB, said that high risk groups must be prioritised by the HSE in inspections and for enforcement as it is thought that the biggest risk groups have a 40% increased risk of lung cancer due to diesel exposure.

Terry said: “Lung cancer from diesel fumes should immediately be added to the list of prescribed industrial diseases in the UK.” Dr Christopher Wild, director of the IARC, agrees that the conclusion sends a strong signal that public health action is warranted.
