title: [Do advers health effects of chrysotile and amphibole asbestos differ?].
abstract: Due to the current query whether the predominantly used chrysotile (white) asbestos comprises health risks we performed a literature search including in vitro and animal experiments as well as epidemiological studies.As shown by epidemiological studies chrysotile causes less pleural fibrosis and mesotheliomas when compared with other asbestos types. However, its otherwise inflammatory, toxic, carcinogenic, and fibrosis-inducing effects correspond to those of other occupationally relevant asbestos types. This is based on clinical, animal as well as on in-vitro findings. This means that denying a causal relationship, e. g. in a case with lung fibrosis (= asbestosis) or lung cancer with an asbestos load of 25 fiber-years in the absence of identification of a significant concentration of asbestos fibers or asbestos bodies in the lung (see so-called "hit and run" phenomenon), contradicts the medical-scientific knowledge.
