Exposures to carbon monoxide (CO) and nitrogen dioxide (NO2) were determined in seven enclosed ice skating rinks and an outdoor rink. The uptake of CO was also determined by the difference in alveolar CO concentration of the non-smoking hockey players before and after games. Carbon monoxide concentrations in enclosed rinks ranged from 4 to 117 ppm and NO2 concentrations from 342 to 2729 ppb for 2 h hockey games. The CO uptakes were linearly related to the ambient CO concentrations. Alveolar CO of the hockey players increased on average by 0.53 ppm per 1 ppm CO exposure over 2 h. Considering the CO and NO2 levels currently measured in enclosed ice skating rinks, indoor air quality guidelines or standards should be established. It is recommended that 1 h maximum allowable limits of 20 ppm CO and 250 ppb NO2 be established.
在七个封闭的溜冰场和一个室外溜冰场测定了一氧化碳（CO）和二氧化氮（NO₂）的暴露情况。还通过非吸烟曲棍球运动员比赛前后肺泡CO浓度的差异来测定CO的摄入量。对于2小时的曲棍球比赛，封闭溜冰场中的一氧化碳浓度范围为4至117 ppm，二氧化氮浓度范围为342至2729 ppb。CO摄入量与环境CO浓度呈线性相关。曲棍球运动员的肺泡CO在2小时内每暴露于1 ppm CO平均增加0.53 ppm。考虑到目前在封闭溜冰场中测得的CO和NO₂水平，应制定室内空气质量指南或标准。建议制定CO的1小时最大允许限值为20 ppm，NO₂为250 ppb。
