Carcinogenicity of asbestos has been well established for decades and it has similar approval standards in most advanced countries based on a number of studies and international meetings. However, Korea has been lagging behind such international standards. In this study, we proposed the approval standards of an occupational cancer due to asbestos through intensive review on the Helsinki Criteri...

In Japan, crocidolite had been used for asbestos cement pipe and spraying, and amosite had been used for building board and spraying. These two types of asbestos had stopped to use in Japan in the late 1970s. An extreme increase in imported asbestos (all 3 commercial types) was observed between 1960 and 1974. In 1960, 77,000 tons of asbestos were imported, and reached the peak as 352,316 tons i...

BACKGROUND Asbestos-related diseases are still a major public health problem. The World Health Organization (WHO) has estimated that 107,000 people worldwide die each year from mesothelioma, lung cancer, and asbestosis. We review what is known about asbestos use, production, and exposure and asbestos-related diseases in the world today, and we offer predictions for the future. Although worldwid...

There is recent mounting evidence that nanoparticles may have enhanced toxicological potential in comparison to the same material in the bulk form. The aim of this study was to develop a new method for unmask asbestos nanofibers from Formalin-Fixed, Paraffin-Embedded tissue. There is an increasing amount of evidence that nanoparticles may enhance toxicological potential in comparison to the sam...

Mesothelioma, a malignant cancer of the pleura, is almost exclusively associated with asbestos exposure.1 What will it take to eradicate this highly preventable cancer? Despite the scientific consensus that exposure to asbestos fibres causes deadly diseases, we continue to use asbestos in products designed ostensibly to improve quality of life. For example, asbestos is still used in automobile ...

Meurman, L. O., Kiviluoto, R., and Hakama, M. (1974). British Journal ofIndustrial Medicine, 31, 105-112. Mortality and morbidity among the working population of anthophyllite asbestos miners in Finland. A study has been made in Finland of the effects of anthophyllite asbestos on mortality and morbidity of 1 092 asbestos workers first employed at two mines between 1936 and 1969; 95% of workers ...

In spite of hard epidemiological and clinical evidence associating asbestos fibre with asbestosis and cancer, the issue is controversial and likely to remain so. The focus is now shifting to non-occupational exposure, differential risk to various asbestos fibre types and the relatively low level of carinogenicity of the chrysotile form. This creates further space for scientific debate and the o...

Cellular mechanisms of asbestos toxicity rely, at least in part, on the chemical composition of these minerals. Iron ions are directly involved in the accepted mechanism of fiber toxicity because they constitute active centers where release of free radicals and reactive oxygen species takes place. Although no current technology is available for the remediation of asbestos polluted sites, the so...

Mesothelioma, a rare tumor, is highly correlated with asbestos exposure. Mesothelioma, similar to all asbestos-related diseases, is dose/intensity dependent to some degree, and studies showed the risk of mesothelioma rises with cumulative exposures. Multiple processes occur in an individual before mesothelioma occurs. The impact of mesothelioma in the United States has been continuous over the ...

BACKGROUND Construction site supervisors are exposed to many chemicals, dusts, and metals including asbestos. Asbestos is a hazardous chemical that is carcinogenic. Laryngeal cancer is not a rare disease in Korea. The most common causes of this disease are tobacco and alcohol, and representative occupational cause is asbestos. However, up to now, no case of laryngeal cancer induced by asbestos ...
