| Abstract |
Faced with high levels of supervisory staff exposure to nitrogen trichloride and high levels of combined chlorine in pool water, indoor swimming pool operators increasingly adopt additional water treatment systems based on UV irradiation. This technology results in the formation of undesired by-products such as chloroform (an IARC class 2B carcinogen). For eight weeks, INRS monitored chloroform and nitrogen trichloride concentrations in water from two pools equipped with low and medium pressure lamps respectively. This study revealed the significant contribution of UV irradiation to chloroform formation and to the possible increase of dissolved nitrogen trichloride. |
