“…However, there was slight decrease in the value for the study group. These findings contradict those of Wonsurakiat et al, Singh et al, Pal et al, and Sharat et al who found consistent difference in FVC and FEV1 between TPP exposed to vehicular emission and those not exposed [15][16][17][18].…”

BACKGROUND: The present study was aimed to assess pulmonary functions in the traffic police personnel (TPP) posted on traffic duty in Kathmandu valley, Nepal. METHODS: The study group consisted of 17 females and 89 males, constituting 16% and 84% of the total police personnel studied, respectively. In the control group of 25 individuals, 16% (n=4) were female and 84% (n=21) were male. Portable desktop spirometer was used for the pulmonary function test (PFT) measurements. RESULTS: It is seen that in females as compared to males, PFT parameters show a significant decrease. One-way ANOVA conducted to compare the effect of duration of air pollution exposure showed that there is a significant variation in PFT parameters among the groups. The exposure duration has significant effect on the PFT parameters. CONCLUSION: Greater the officers are engaged in traffic duty for years, greater is the decrement in their lung functions test.

“…In a study carried out in Hong Kong, PM 10 concentrations near busy streets were found to range from 25.56 to 337.4 μg/m 3 which were significantly higher than the nearby fixed station data [22]. A study conducted in Jaipur to evaluate pulmonary effects of traffic pollution on traffic police found higher respiratory morbidity in traffic policemen compared to an unexposed outdoor group [23]. These studies emphasize the need for personal monitoring of air pollutants which could reduce misclassification of exposure.…”

Air quality monitoring (PM 2.5 , CO, NOx, SO 2 and EC/OC) was carried out at highway toll plazas, municipality toll plazas and control sites (n = 23) in the National Capital Region of Delhi, to determine the exposure of toll plaza workers to air pollution and its effect on lung function. Lung function indices (n = 45) were also measured for these workers. The results reveal the high level of air pollution at almost all locations with PM 2.5 values exceeding the national permissible limit except at a few control sites. Observed reduction in lung function indices was significant over years of occupational exposure even after adjusting for age, amongst non-smoking outdoor workers. This study found pollutant concentrations were highest at municipality toll plazas with minimum protective work area. The paper suggests measures to reduce the exposure of outdoor workers.

“…23 In Jaipur, India, a significant decline in percentage of the predicted normal values of FEV 1 for TP (n ¼ 300) was observed compared with a healthy control group (n ¼ 164). 21 For TP (n ¼ 1603) in Hong Kong, prevalence of nonspecific respiratory disease in polluted, moderately polluted, and suburban areas was 13.0%, 10.9%, and 9.4%, respectively, indicating an association between prevalence of respiratory symptoms and urban traffic air pollution. 22 Although the sample size is limited, results on respiratory symptoms and spirometry do not show strong differences across occupations.…”

Kathmandu Valley, Nepal, has severe air pollution, although few studies examine air pollution and health in this region. To the best of our knowledge, no previous studies in Nepal used time-activity diaries or conducted personal monitoring of individuals' exposures. We investigated personal exposure of particulate matter (PM) with aerodynamic diameter ≤2.5 μm (PM(2.5)) by location, occupation, and proximity to roadways. PM(2.5) monitoring, time-activity diary, respiratory health questionnaire, and spirometer testing were performed from 28 June 2009 to 7 August 2009 for 36 subjects, including traffic police (TP), indoor officer workers next to main road (IOWs_NMR) and away from main road (IOWs_AMR), in urban area (UA), urban residential area, and semi-UA (SUA). TP had the highest exposure of all the occupations (average 51.2 μg/m(3), hourly maximum >500 μg/m(3)). TP levels were higher at the UA than other locations. IOW_NMR levels (averaged 46.9 μg/m(3)) were higher than those of IOW_AMR (26.2 μg/m(3)). Exposure was generally higher during morning rush hours (0800-1100 hours) than evening rush hours (1500-1800 hours) for all occupations and areas (78% of days for TP and 84% for urban IOW). PM(2.5) personal exposures for each occupation at each location exceeded the World Health Organization ambient PM(2.5) guideline (25 μg/m(3)). Findings suggest potential substantial health impacts of air pollution on this region, especially for TP.

Respiratory Morbidity Attributed to Auto-exhaust Pollution in Traffic Policemen of Jaipur, India

Abstract: Respiratory morbidity with respect to lung function tests is observed more in groups working in heavy traffic than the control group.
