Asbestos-Related Diseases and Policies: an Update

Asbestos-related risks have been estimated on the basis of data from the past, when professional exposures were higher. Fibers are present in the environment due to erosion of surface deposits and human activities unrelated to asbestos industry. If searched for, asbestos fibers are frequently found at autopsies. Bias can be encountered in asbestos research e.g. attributing of mesothelioma and lung cancer to asbestos when fibers are present, although cause-effect relationships remain unproven. Some studies rely on work or residence histories of questionable reliability. Asbestos is banned in some countries while others are increasing production and exports. Asbestos is a low-cost material and an excellent reinforcing fiber. Different asbestos types have their technical advantages and preferred application areas. The traffic is safer with asbestos-containing brake linings. Asbestos cement constructions are sturdy and inexpensive. The fireproofing properties of asbestos are well known. It can be reasonably assumed that the non-use of asbestos-containing brakes, fireproofing and insulation lagging has increased the damage and numbers of victims of traffic accidents, fires and armed conflicts. Nowadays, when a probability of conflicts seems to be enhanced, the attitude to asbestos should be changed. Most importantly, asbestos-related science must be separated from economical and political interests. Reliable information can be obtained in lifelong bioassays.
