Growing tobacco plants acquire metals from soil, fertilisers, and industrial pollution. Smoking liberates some of these metals from tobacco into smoke to be inhaled by the smoker and bystanders. This can cause harmful health effects, such as cancer, and liver- and kidney damage. Arsenic, cadmium, nickel and lead are the main contributors to the health risks of metals in smoke. These are results of research conducted by the University of St Andrews (Scotland) commissioned by RIVM.
Testing by manufacturers
During our study, TobReg, the
WHO expert panel set up to advise on the scientific basis of
tobacco product regulation, has recommended that manufacturers test
the levels of arsenic, cadmium, lead and nickel in tobacco. The
results of the present study support the prioritisation of metals
in their list.
