This study aimed to assess the lung capacity of rickshaw pullers in Dhaka city, Bangladesh and their exposure to polluted air and determine their perception toward air pollution-induced disorders.<br> <strong>Methods:</strong> In this survey, a questionnaire and spirometry analysis were used to measure the lung function of 35 subjects, who were nonsmokers and had no prior respiratory problems. A SP10BT spirometer was used in a standing position to measure the forced vital capacity (FVC), one-second forced expiratory volume (FEV₁), FEV₁/FVC, and peak expiratory flow (PEF). Data were analyzed using independent t-test.<br> <strong>Results:</strong> The mean values of FVC, FEV₁, and PEF were significantly lower in the experimental group (urban rickshaw pullers) than the control group (rural rickshaw pullers) (<em>P</em> < 0.001). FEV₁/FVC was also lower, while the difference was not significant. The majority of the subjects had various seasonal and environmental disorders since coming to Dhaka, and 46% of the respondents mostly had eye irritation, fever, and cough during winter, which decreased their ability to pull their rickshaws.<br> <strong>Conclusion:</strong> Air pollution had a measurable adverse impact on the pulmonary function of the urban rickshaw pullers compared to the rural control group.</span></span></div> Rickshaw pullers, Air pollution, Lung function, Perception 47 52 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-391-1&slc_lang=en&sid=1 Abdullah Al Nayeem nayeem@stamforduniversity.edu.bd 100319475328460010341 100319475328460010341 Yes Center for Atmospheric Pollution Studies (CAPS), Department of Environmental Science, Stamford University Bangladesh, Dhaka-1209, Bangladesh.
