Hello visitor! Thank you for taking the time to read this article.
There is a health epidemic that has been known for many decades and it involves exposure to hazardous asbestos. One interesting study is called, The Hazards of Chrysotile Asbestos: A Critical Review by Philip J. Landrigan, William J. Nicholson, Yasunosuke Suzuki and Joseph Ladou - INDUSTRIAL HEALTH - Vol.37 , No.3(1999)pp.271-280. Here is an excerpt: Abstract: Chrysotile, or white, asbestos is the dominant form of asbestos in international commerce today. It accounts for 99% of current world asbestos production of 2 million tonnes. Chrysotile is an extremely hazardous material. Clinical and epidemiologic studies have established incontrovertibly that chrysotile causes cancer of the lung, malignant mesothelioma of the pleura and peritoneum, cancer of the larynx and certain gastrointestinal cancers. Chrysotile also causes asbestosis, a progressive fibrous disease of the lungs. Risk of these diseases increases with cumulative lifetime exposure to chrysotile and rises also with increasing time interval (latency) since first exposure. Comparative analyses have established that chrysotile is 2 to 4 times less potent than crocidolite asbestos in its ability to cause malignant mesothelioma, but of equal potency of causation of lung cancer. The International Agency for Research on Cancer of the World Health Organization has declared chrysotile asbestos a proven human carcinogen. Sales of chrysotile asbestos have virtually ended in Western Europe and North America, because of widespread recognition of its health hazards. However, asbestos sales remain strong in Japan, across Asia and in developing nations worldwide. The claim has been made that chrysotile asbestos can be used safely under certain conditions in those nations. That claim is not accurate. The Collegium Ramazzini, an international learned society in environmental and occupational medicine, has called for an immediate worldwide ban on all sales and uses of all forms of asbestos, including chrysotile. The rationale for this ban is threefold: (1) that safer substitute materials are readily available, (2) that controlled use of asbestos is not possible, and (3) that the health risks of asbestos are not acceptable in either the industrialized or the newly industrializing nations.
Another interesting study is called, Respiratory Cancer Incidence in Swedish Construction Workers Exposed to Man-Made Mineral Fibres and Asbestos by G. Engholm, A. Englund, A. C. Fletcher and N. Hallin. - Ann. occup. Hyg., Vol. 31, No. 4B, pp. 663-675, 1987. Here is an excerpt: The incidence of respiratory cancer has been studied in relation to exposure to man-made mineral fibres (MMMF) within a large cohort of Swedish construction workers. The cohort comprised some 135 000 men, who were all examined by Byggh
