Purpose

Global warming and air pollution are among the most important problems all over the world. Considering the key role of traffic officers who saliently deal with traffic management and are in full, constant and direct exposure to thermal stress and air pollution index, this study aims to investigate the simultaneous effects of these factors on the body temperature of traffic officers in the main squares of Tehran.

Methods

This study was conducted among 119 traffic officers who were working in 29 squares of Tehran, located near the active pollutant’s stations during 2017. Samples were selected by the census method. Environmental parameters such as air temperature (dry and wet), radiation temperature, the level of air pollution in the main squares and characteristics of officers such as body temperature and the Wet-Bulb-Globe-Temperature (WBGT) index were evaluated. Data were analyzed through independent samples t-test and factorial ANOVA with a p value of p ≤ 0.05 in SPSS software.

Results

There was no significant relationship between air pollution and ear temperature, but there was a statistically significant difference between the wet-bulb temperature and the ear temperature (t = 26.4, P < 0.001). The interaction effect of air pollution and wet-bulb temperature on the ear temperature was also significant (F = 3.98, P = 0.048).

Conclusion

Exposure to heat and air pollution affects body temperature, with its greatest impact on the temperature of the ear. More studies are recommended to be conducted in these field and other factors such as demographic and environmental factors at different times of the year should be investigated. Accordingly, some interventions should be implemented to reduce the vulnerability of officers based on the findings of the research.

热应激和空气污染对德黑兰交通官员体温的同时影响。

目的

全球变暖和空气污染是全世界最重要的问题之一。考虑到交通管理人员在交通管理中发挥的关键作用,并全面、持续、直接地暴露于热应激和空气污染指数,本研究旨在探讨这些因素对交通管理人员体温的同时影响。德黑兰的主要广场。

方法

这项研究是在 2017 年期间在德黑兰 29 个广场工作的 119 名交通官员中进行的,这些交通官员位于活性污染物站附近。样本是通过人口普查方法选择的。环境参数,如空气温度(干湿)、辐射温度、主要广场的空气污染程度以及体温和湿球温度(WBGT)指数等官员的特征。通过独立样本 t 检验和因子 ANOVA 分析数据,在 SPSS 软件中p值为p  ≤ 0.05。

结果

空气污染与耳温无显着相关性,但湿球温度与耳温差异有统计学意义(t=26.4,P  <0.001)。空气污染和湿球温度对耳温的交互作用也很显着(F = 3.98,P  = 0.048)。

结论

暴露于高温和空气污染会影响体温,其中对耳朵温度的影响最大。建议在这些领域进行更多研究,并应调查一年中不同时间的人口和环境因素等其他因素。因此,应根据研究结果实施一些干预措施,以减少官员的脆弱性。
