The International Agency for Research on Cancer, a part of the World Health Organization, had previously labelled diesel exhausts as probably carcinogenic to humans.
IARC has now labelled exhausts as a definite cause of cancer, although it does not compare how risky different carcinogens are. Diesel exhausts are now in the same group as carcinogens ranging from wood chippings to plutonium and sunlight to alcohol. It is thought people working in at-risk industries have about a 40% increased risk of developing lung cancer.
