The risk of getting lung or bladder cancer following occupational exposure to
polycyclic aromatic hydrocarbons (PAHs) has been quantified for the first time,
in a research report published by the Health and Safety Executive (HSE).
PAHs are a group of chemicals that are found in every industry, especially
where substances are burned, such as in aluminium smelting and coke production.
They are air-based and can be breathed in.Exposure to PAHs has long been known
to cause lung and bladder cancer, but, until now the overall risks had not been
quantified.This research report, commissioned by HSE, ‘Cancer risk following
exposure to polycyclic aromatic hydrocarbons (PAHs): a meta-analysis’, found
that people who are exposed to one microgram per metre cubed of PAHs through
work over 40 years, are eight per cent more likely to contract lung cancer,
i.e. their lung cancer risk increases from 80 per 1000 to 86 per 1000.The
results for the risks of contracting bladder cancer were less certain, due
mainly to the much smaller number of cases of this rarer cancer.
