A careful examination of studies shows that this statement is grossly misleading and represents only selective parts of the scientific info.
Compared to products coming from the petrochemical or metallurgical industries, chrysotile – cement products consume much less energy; in fact, the largest proportion of energy consumption goes into the production of cement.
According to technological design, most of wastewater from production process is recycling to production line. However, factually some small quantity of wastewater is discharged to surrounding environment.
Process selection – For the new projects, it should select the process line using bulk-load cement (cement is transported by pneumatic conveyor), automatic debaggers and bag destroyer machine, wet grinding
Hazardous and risk factors in asbestos-cement roofing sheets productiMain materials used for manufacturing asbestos roofing sheet are cement and asbestos with a small amount of Kraft paper powder, of which cement occupied 85% and chrysotile occupied 10%.
Access to safe drinking-water is enssential to healt, a basic human right and a component of effective policy for heath protection…
One of the primary goals of WHO and its member states is that “all people, whatever there is states of development and there is social and economic conditions, have the right to have access to an adequate supply of safe drinking water. A major WHO function to achieve such goals is the responsibility “to propose regulations, and to make recommendations with respect to internation health matters…”
The chrysotile industry created and is now implementing a responsible-use programme that is based on the controlled-use approach to regulating chrysotile. Representatives of the world’s major chrysotile exporting mines signed an agreement whereby they committed to supply chrysotile fibre only to those companies that demonstrate compliance with national health and safety regulations.
In the West, owing to the climatic conditions their industrial buildings and houses are kept closed to conserve heat. There, when harmful effects of asbestos were not known, asbestos fibre used to be extensively sprayed on ceilings and structures of industrial buildings and houses for thermal insulation. Friable low-density asbestos insulation boards were also used as inner roof to provide better fire protection.
It’s not completely difficult for us do searching about “100,000 annual death figure from asbestos-related disease” on Google. Even if be written in any kind of language, these information are always dimly and vague. Have any person ever demanded himself where are these figure from?
There is growing scientific evidence demonstrating that asbestos induced lung cancer, such as asbestosis, is a threshold phenomenon. Low exposures to chrysotile do not present a detectable risk to health. Since total dose over time determines the likelihood of the occurrence and progression of disease, studies suggest that the risk of an adverse outcome may be low, even if high exposures are experienced for a short duration.
