· 1 Introduction Respiratory disease associated with smoke and dust exposure is a global issue that disproportionately impacts developing nations [1 2 3 4] The quarry industry in Libya is one of the largest industries and its workers are routinely exposed to dust whose aerodynamic diameter fall within the respirable size range throughout various stages in the quarrying process [2 3]
Respirable dust includes very small particles of dust diameter less than 10 microns that when inhaled are able to reach the deepest parts of the lungs Workers exposed to elevated levels of airborne respirable dust have an increased risk of developing MDLD such as pneumoconiosis chronic obstructive pulmonary disease COPD and lung cancer Often a worker with MDLD has more
