0.05). Conclusion: The average maximum aerobic capacity was higher than other occupational groups but lower than the mean of other firefighters. Therefore, it is recommended to increase their aerobic capacity with a regular exercise program, physical fitness, and weight control; and pre-employment examinations should be performed more carefully to ensure their physical fitness is commensurate with the job.]]>

vanadium> chromium> nickel> copper> arsenic> cobalt. Comparison of the concentration of dust elements with the background concentration and the results of principal component analysis and correlation tests showed that the concentration of all metals in the dust is probably influenced by two man-made sources in the area. The highest and lowest saturation degrees obtained were for manganese and cobalt, respectively. Based on the CF index, the manganese, cobalt, and vanadium were in low, medium, and high levels of pollution, respectively. Also, Arsenic, chromium, and nickel were classified in medium to high and copper in low to high classes. According to ERP and PERI indices, all heavy metals were classified in low pollution class. Conclusion: The investigated industries in this study have an important role in increasing the concentration and mobility of heavy metals in falling dust.]]>
