I nhalation of airborne nickel (Ni) and chromium (Cr) in workplaces causes a variety of respiratory ailments. This adversely affects the productivity of the employees. A study was therefore carried out in 6 plants, on 233 production workers, to investigate the influence of Ni and Cr exposure on their respiratory systems. Air samples were collected in the breathing zones of these workers and subsequently analysed for Ni and Cr using atomic absorption spectrophotometery. Information on the previous medical history of the workers was obtained using questionnaires. Their lung functions were further investigated using a spirometer in order to assess the influence of these metals on their respiratory functions. The study established that 26.2% of the workers had respiratory diseases that were associated with bronchitis, wheezing, shortness of breath, asthma, sneezing attacks and tonsillitis among other related symptoms. Most of these workers were from steel and scrap welding, leather tanneries and paint manufacturing plants. The breathing zone air of the afflicted workers had significantly high mean concentrations of 6.4 � 4.4 �g/m3 Ni and 9.6 � 5.3 �g/m3 Cr when compared to those who were not affected (4.9 � 3.2 �g/m3 Ni and 4.4 � 3.8 �g/m3 Cr). A high proportion of the workers also had reduced lung functions. All clinically diagnosed cases of both severe and mild airway obstructions were more than those that were self reported in the questionnaires. The study therefore recommended regular respiratory medical surveillance for workers in Cr and Ni related industries, for early intervention.
