Remember I talked about this disease a couple of months back?  For those who was not able to read the article, mesothelioma is a kind of cancer that can be caused by a significant level of exposure to asbestos.  This is according to the studies on groups of workers with cummulative exposure ranging from 5 to 1,200 fiber-year/ml which can be a result from a 40 years occupational exposure to air concentrations of 0.125 to 30 fiber/ml.  However, I was a bit puzzled about this for from what I remember, most developed countries have stopped using asbestos in constructions way back in the 90’s I think, because of the studies on Mesothelioma.  But it turned out, asbestos is not only used on buildings.  Because of its good heat and electric insulation quality it is used on a lot of other products that we use everyday.  From brake pads and clutches to boilers and furnaces.  So people who works as automechanics, broiler makers, merchant marines, carpenters, painters etc. has a high risk of getting an exposure to the said mineral.  Sheesh, no wonder there are still around 3000 new cases of Mesothelioma in the US and majority of them are men.
