• 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 (FE no ) were measured. Results: Compared to rehabilitation facilities, the mean trichloramine concentrations in the adventure facilities were higher, both personal (80 μg/m 3 ( n   =  41) vs 19 μg/m 3 ( n  = 21)) and stationary (183 μg/m 3 ( n  = 51) vs 23 μg/m 3 ( n  = 32)), with higher frequency of ocular and respiratory symptoms. Low stationary endotoxin levels (<0.64 to 25 EU/m 3 ) were found, compared to the reference value (90 EU/m 3 ). Conclusions: Higher trichloramine concentrations in air and more ocular and respiratory symptoms in adventure facilities call for adequate occupational exposure limits.
