The daily number of hospital admission due to respiratory diseases can have a great variability. This variability could be explained by different factors as year seasons, temperature, pollution levels among many others. Hexavalent chromium [(Cr (VI)] and nickel (Ni) are among the heavy metals with established history of detrimental health effects. Epidemiological studies have consistently shown that chronic exposure to Ni and Cr (VI) compounds through inhalation is associated with higher incidences of lung cancers and respiratory ailments. Health concerns are therefore raised over these metals due to possible exposure because of their widespread use and availability in manufacturing processes. Elevated temperatures that are often involved in most industrial activities, including welding result in emission of particulate matter in the form of metal dust, fumes and oxides, which are easily inhaled. These particulate materials are then absorbed and thereafter penetrate deeper into membranes of human lungs, leading to respiratory manifestations such as those of severe bronchial complications, lung emphysema, chronic obstructive pulmonary disease, renal dysfunction and death. It is also not clear whether other chemicals used in the manufacturing processes may aggravate the respiratory problems apart from Ni and Cr exposure.Periodical medical examinations are critical in monitoring the health of workers in order to prevent respiratory ailments. It is necessary that welders, tanners and, to an extent, paint manufacturers among other establishments that use Cr and Ni in their manufacturing activities include pulmonary function tests in their medical surveillance. This will subsequently enable the early detection of respiratory obstruction and airway resistance disorders and the possible removal of the affected workers from their respective workplaces prior to chronic impairment.(Were FH, Charles Moturi M, Kamau GN, Wafula GA, Respiratory Diseases Due to Occupational Exposure to Nickel and Chromium among Factory Workers in Kenya)
