dc.description.abstractThe increase of industrial activities in the Angul-Talcher area, Orissa resulted in indiscriminate disposal of waste into the environment leading to the deterioration of the quality of the environment, which affects the health of the workers as well as the community people. Considering the magnitude of the problem, the pulmonary function study had been carried out in one of the largest aluminium producing plant of the country as well as surrounding community people. Aluminium is produced from oxides of alumina by Hall-Heroult smelting process. The electrolysis called as aluminium smelting is carried out in an electrolytic cell (pot) having anode, cathode and electrolyte. The aluminium is deposited in the cathode and the oxygen moves towards anode is released. The workers working at the captive power plant (CPP), which is necessary to meet the power demand of the smelter plant were also investigated. 180 smelter plants workers (non-smoker 129, smoker-51) of different sections and 37 captive power plant workers (non-smoker 29, smoker-8) had undergone pulmonary function tests. Besides these, 85 persons from the surrounding community (non-smoker-66, smoker-19) were also investigated. The workers were all male. Spirometric assessments of Vital Capacity (VC), Forced Vital Capacity (FVC), and Peak Expiratory Flow Rate (PEFR) were done by Spirovit-sp-10 (Schiller Health Care Ltd, Switzerland) and Wrights Peak flow meter (Clement and Clarke, UK). Different lung volumes like FEV1, FEV1%, and flow rates like FEF200-1200ml, FEF25-75% and FEF75-85% were calculated from the same tracings pulmonary function test (PFT) results of the workers according to different age groups, duration of exposures and smoking habits. The mean values of SVC, FVC and FEV1 of smelter plant workers were found higher compared to the community people but the values of captive power plant workers were very much close to the values of the community people. A gradual decrement of the PFT values was found as duration of exposure increased. Lung volumes and the flow rates were decreased as age increases but in some age groups that trend was not followed. It has been found that in each category of subjects, smokers have the higher mean pulmonary function values compared to the non-smokers. Except the community people in all other cases the different flow rates were found higher in nonsmokers compared to smokers. The restrictive, obstructive and combined restrictive and obstructive types of impairments among the subjects were noticed. The respiratory impairment among the workers as a whole was found higher in smelter plant workers (9.44%) followed by the captive power plant workers (5.40%) and the community people (2.35%). In smelter plant workers both the restrictive and obstructive impairments were found higher compared to captive power plant and the community people.en_US
