[Is one single exposure to asbestos life-threatening?].

The media occasionally reports on possible asbestos exposure during demolition of houses in an urban setting. The risk for the development of any asbestos-related cancer in these settings is considered to be lower than for that in occupational exposure. Offermans et al. examined a Dutch cohort of 58,279 workers in the period from 1986 to 2007. They concluded that the risk of lung cancer, laryngeal cancer and mesothelioma increased with exposure to asbestos. The risk of development of lung cancer was higher for anyone with increased years of exposure to asbestos fibre combined with a smoking habit. The study was well conducted, but exact data on fibre concentration and type of asbestos are lacking. We suggest that occasional exposure to asbestos poses hardly any risk for the general population. However, rules and regulations for the removal of asbestos-containing material remain important as asbestos exposure remains a serious health risk, especially in smokers.
