摘要

为了保持健康,人们经常去体育设施。本研究旨在评估健身俱乐部在封锁后(由于COVID-19大流行)的空气污染和舒适参数,重点关注颗粒物(PM10, PM2.5)和气态污染物(总挥发性有机化合物- tvocs,二氧化碳- CO2和一氧化碳- CO)。2020年10月,在一个健身中心(葡萄牙波尔图)连续10天进行抽样。结果表明:室内PM10在1.4 ~ 122.5µg/m3之间,PM2.5在0.8 ~ 25µg/m3之间;总体水平符合现行立法。TVOC均值在不占用时为0.39 mg/m3,在运动对象在场时为0.43 mg/m3,也达到0.6 mg/m3的限值)。平均CO2为1400 mg/m3,时间最大值(2660 ~ 2894 mg/m3)超过保护阈值。最后,温度和相对湿度超过了推荐的舒适水平,特别是在团体活动课程期间。

Air Quality in Fitness Centers
To stay healthy, people frequent sports facilities. This work aimed to evaluate air pollution and comfort parameters in a fitness club in the post lockdown period (due to the COVID-19 pandemic), focusing on particulate material (PM10, PM2.5) and gaseous pollutants (total volatile organic compounds -TVOCs, carbon dioxide - CO2, and carbon monoxide – CO). Sampling was carried out for 10 consecutive days in October 2020 in one fitness center (Oporto, Portugal). The results showed that indoor PM10 ranged from 1.4 to 122.5 µg/m3 and PM2.5 was between 0.8 and 25 µg/m3; the overall levels were in accordance with the current legislation. TVOC means were 0.39 mg/m3 when not occupied and 0.43 mg/m3 when exercising subjects were present, thus also fulfilling the limit 0.6 mg/m3). Average CO2 was 1400 mg/m3 with temporal maxima (2660-2894 mg/m3) exceeding the protection threshold. Finally, temperature and relative humidity exceeded the recommended comfort levels, especially during group activity classes.
