BACKGROUND The incidence of asbestos-induced human cancers is increasing worldwide, and considerable evidence suggests that reactive oxygen species (ROS) are important mediators of these diseases. Our previous studies suggested that mitochondria might be involved in the initiation of oxidative stress in asbestos-exposed mammalian cells. OBJECTIVE We investigated whether mitochondria are a pot...

BACKGROUND National disparities in asbestos use will likely lead to an unequal burden of asbestos diseases. OBJECTIVES As economic status may be linked to asbestos use, we assessed, globally, the relationship between indicators of national economic development and asbestos use. METHODS For the 135 countries that have ever used asbestos, per capita asbestos use (kilograms per capita per year...

BACKGROUND We assessed the cancer risks of four different Finnish asbestos-exposed cohorts. We also explored if the cohorts with varying profiles of asbestos exposure exhibited varying relative risks of cancer. METHODS The incident cancer cases for the asbestos-exposed worker cohorts were updated to the end of 2012 using the files of the Finnish Cancer Registry. The previously formed cohorts ...

Asbestos is a mineral-mined form the rocks, consisting in amosite (brown asbestos), crocidolite (blue asbestos) and÷or chrysotile (white asbestos) used in many industries. Researches about the exposure to asbestos dust and asbestosis related diseases started almost a century ago. The first case report of fatal asbestosis disease was published in 1906, in England, by Dr. Hubert Montague Murray. ...

In 1999, the Collegium Ramazzini—an independent academic society founded to advance the study of occupational and environmental health concerns—issued a call for an international ban on the mining, manu facture, and use of asbestos (Collegium Ramazzini 1999). In the Commentary by LaDou et al. (2010) in this issue, the Collegium repeats its call for a universal ban. In our opinion, the reasons f...

The main pathological effects attributed to asbestos are carcinogenesis and fibrogenesis. Statistical studies have shown that asbestos workers may expect a higher morbidity not only from cancer of the lung and mesothelioma but also from cancer at other sites. Carcinomas have been reported in animals following the injection of asbestos, but the production of carcinomas by inhaled asbestos is les...

The waste generated by the periwinkle (Tympanotonus fuscatus) shell cannot be undermined. In coastal communities worldwide, is a major source of proteins and other vital minerals in most delicacies. shells these aquatic species, notable for their nutrient provision, contribute to environmental degradation because indiscriminate disposal. absence proper management program leads blockage drainage...

Asbestos has been declared a proven human carcinogen by the U.S. Environmental Protection Agency and by the International Agency for Research on Cancer of the World Health Organization. Since 1983, the European Union has enforced health protection directions in this field, which have been the basis for legal acts of Member States. The Estonian Republic is a country where asbestos and asbestos-c...

The predominant asbestos fibre type used in the production of asbestos cement is chrysotile. The use of asbestos in relation to fibre type in a Norwegian asbestos cement plant during 1942-80 was 91.7% chrysotile, 3.1% amosite, 4.1% crocidolite, and 1.1% anthophyllite respectively. Electron microscopy and x ray microanalysis of lung tissue samples of asbestos cement workers who had died of malig...

BACKGROUND It has been suggested that asbestos exposure affects lung function, even in the absence of asbestos-related pulmonary interstitial or pleural changes or emphysema. METHODS We analyzed associations between well-known asbestos-related risk factors, such as individual cumulative asbestos exposure, and key lung function parameters in formerly asbestos-exposed power industry workers (N ...
