Objective: We aimed to evaluate the relationship between swimming pool pollutants and allergic rhinitis in swimming pool workers. Materials and methods: Twenty-seven indoor pool workers (group 1) and 49 control subjects (group 2) were enrolled in the study. A skin prick test was performed and a nasal smear was obtained from each subject to evaluate rhinitis. Results: When the groups were compared in terms of epithelial cells, group 1 had significantly more epithelial cells than group 2. When the groups were compared with regard to eosinophils, group 1 had significantly more eosinophils than group 2. The skin prick test results for both groups were not significantly different. Conclusion: Indoor pool workers showed severe symptoms of rhinitis and eosinophilic nasal cytology, likely due to chlorine. Nasal cytology is an easy-to-administer diagnostic test and can be used to follow up rhinitis in indoor pool workers, along with nasal endoscopy, a detailed clinical history and a skin prick test.
