Swimming teachers, and others who spend time near chlorinated pools, face an increased risk of breathing problems.
Chlorine reacts with urine and sweat to create chemicals called chloramines that irritate the respiratory tract. A research team surveyed more than 600 swimming pool employees and measured levels of trichloramine, the most volatile type of chloramine, at 38 swimming pools.
Swimming instructors were more than twice as likely to suffer frequently from sinusitis or sore throat, and more than three times as likely to have chronic colds, than pool workers with less trichloramine exposure, such as catering employees or receptionists.
Compared to the general population, employees with high levels of exposure were at a 40 percent greater risk for tightness of the chest, and were over 700 percent more likely to suffer breathlessness while walking.
