CHAPTER 35: Indexes of Disinfection By-Products (DBPS) Exposure and Irritant Symptoms in Swimming Pool Workers

In two previous studies we evaluated the frequency of different ocular and respiratory symptoms in a group of pool workers in relation to their exposure to DBPs. Recently, we were able to extend the monitoring to a further group of workers. The aim of this study was to re-evaluate associations between different irritant health effects and occupational exposure to both THMs and NCl₃ in this enlarged cohort of subjects in order to assess the role played by different index of exposure to irritant chemicals. THMs exposure was evaluated by both environmental and biological monitoring, while NCl₃ levels were investigated in environmental air.
