OBJECTIVE
To study occupational exposure totrichloramine and endotoxins in air at adventure and rehabilitation swimming pool facilities from an adverse health effects perspective.
METHODS
Air concentrations of trichloramine and endotoxins were measured in five adventure and 10 rehabilitation facilities. Respiratory and ocular symptoms were self-reported, and spirometry and fraction of exhaled nitric oxide (FEno) were measured.
RESULTS
Compared to rehabilitation facilities, the mean trichloramine concentrations in the adventure facilities were higher, both personal (80 μg/m3 (n = 41) vs 19 μg/m3 (n = 21)) and stationary (183 μg/m3 (n = 51) vs 23 μg/m3 (n = 32)), with higher frequency of ocular and respiratory symptoms. Low stationary endotoxin levels (<0.64 to 25 EU/m3) were found, compared to the reference value (90 EU/m3).
CONCLUSIONS
Higher trichloramine concentrations in air and more ocular and respiratory symptoms in adventure facilities call for adequate occupational exposure limits.
目的
从健康影响的角度研究冒险和康复游泳池设施空气中三卤胺和内毒素的职业暴露情况。
方法
在五个冒险设施和十个康复设施中测量空气中三卤胺和内毒素的浓度。呼吸和眼部症状由自我报告，并且进行了肺活量测定和呼出气一氧化氮分数（FEno）的测量。
结果
与康复设施相比，冒险设施中的三卤胺个人浓度（80μg/m3（n=41）比 19μg/m3（n=21））和固定浓度（183μg/m3（n=51）比 23μg/m3（n=32））均更高，且眼部和呼吸道症状的发生频率更高。与参考值（90EU/m3）相比，空气中的低固定内毒素水平（<0.64 至 25EU/m3）。
结论
空气中更高的三卤胺浓度和冒险设施中更多的眼部和呼吸道症状需要制定足够的职业暴露限值。
