Air Pollution - Essay ExampleThe surface of asbestos particles in relation to their risk to humans has been discussed. The methods used in assessing the risk of asbestos will be given. The global standards and problems associated with asbestos will be discussed. well-nigh asbestos lineaments that are respired are invisible to the unaided human eye since their size is just 3 to 20 micrometers long and brush off be as thin as 0.01 micrometers (Benarde, 1990, pp. 187-203). The human h publicise varies in size from 17 to 181 micrometer in width. Asbestos fibers eventually form after minerals initially cooled and crystallized, were shaped by the polymeric molecules that lined up parallel to each other and therefore form oriented crystal lattices. The crystals formed clear three cleavage planes, exactly like other gemstones and minerals have. But in the case of asbestos crystals, there are two cleavage planes that are to a great extent, much adynamicer than the third direction. When enough pull is applied, they are inclined to break along their weakest directions and this result in a linear fragmentation approach pattern and consequently a fibrous form. This process of fracturing can keep happening and one larger asbestos fiber can eventually become the cause of hundreds of much smaller and thinner fibers.As the asbestos fibers get luminance and smaller, they more easily turn out to be airborne and exposure to the human respiratory can result. The asbestos fibers will finally settle but may be re-suspended movement such as air currents. The friability of a product that contains asbestos is a term used to say that the product is so weak in structure and soft that it can be shattered with simple finger crushing pressure. The ataraxis of damage of friable materials makes them to have the most initial concern. The conditions or forces of usage that come into close connectedness with a large amount of non-friable materials that contain asbestos are considerabl y higher than finger pressure.Asbestos fibers can have severe effects on
