The discount in the number of persisting fibers may be associated to excretion of fibers by mucociliary motion or phagocytosis of fibers by alveolar macrophages, and the reduced sizes (length and width) of fibers retained within the lungs may be attributable to dissolution in body fluid or mechanical destruction of fibers 3 The explanation why longer fibers clear faster in comparison with shorter fibers is taken into account to be that longer fibers could primarily deposit in the airways and observe mucociliary clearance while shorter fibers penetrate deeper into the lung periphery. American chemical engineer Charles Corydon Corridor in 1897 developed a know-how to transform molten rock into fibers and initiated the rock wool insulation industry in America.
