In the framework of a cohort study of pregnant women conducted in Brittany (France), we assessed the exposure to trihalomethanes (THM) during pregnancy in a subset by evaluating (1) potential sources of variability in household THM levels; (2) the between- and within-subject variability in THM levels; (3) THM levels in swimming pools; and (4) the role of water-related habits on total THM uptake...

IMPORTANCE Swimming pools can be a vector for transmission of adenovirus ocular infections. Polyhexamethylene biguanide (PHMB) is a disinfectant used in swimming pools and hot tubs. OBJECTIVE To determine whether PHMB is an effective disinfectant against ocular adenovirus serotypes at a concentration used to disinfect swimming pools and hot tubs. DESIGN In vitro laboratory study. INTERVEN...

The fate of organic nitrogen and carbon introduced into a swimming pool by pool users has been studied using a 2.2 m model pool. The study made use of a body fluid analogue, containing the primary endogenous organic amino compounds, and a soiling analogue represented by humic acid. The system was used to examine the effect of organic loading and organic carbon source (i.e. amino or humic acid) ...

fault occurred in the heat reclamation system and simple air extraction was used. For intensively used public swimming pools there are no obvious altematives to chlorine based disinfectants. A survey of bather comfort showed that problems with chlorinous smells are virtually non-existent when the organic contaminants are removed by the powerful oxidising action of ozone.3 In this process swimmi...
