초록

차아염소산 나트륨으로 살균된 수영장 물에 존재하는 크로로포름은 수영장에서 실내공기내에 존재하는 클로로포름 평균농도를 측정하였다: 수영장 A에서는 28.0+-5.7$\mu\textrm{g}$/$m^3$ 그리고 수영장 B에서는 33.6+-6.6$\mu\textrm{g}$/$m^3$. 덧붓여, 수영장 A 및 B의 물에서 측정된 클로로포름 평균농도는 각각 23.9+-6.6$\mu\textrm{g}$/$m^3$ 및 19.5+-7.5$\mu\textrm{g}$/$m^3$이었다. 수영장 A 및 B 의 실내공기내에 존재하는 클로로포름 농도들은 살균제로서 차아염소산나트륨만을 사용한 수영장을 대상으로 측정한 외국의 이전 연구에서 보고된 결과보다 낮았다. 본 연구에서 측정된 물속의 믈로로포름 농도는 서로 유의한 상관관계를 나태내었다(p=0.002 and $R^2$=0.42). 실내 공기 시료채취와 유사한 시간에 실외 공기 시료가 각각 수영장 A 와 B에 가까운 두개의 장소에서 채취되었따. 수영장 A 및 B 근처에서 측정된 실외 공기에서의 클롤로포름 평균 농도는 각각 0.41+-0.15$\mu\textrm{g}$/$m^3$ 및 0.16+-0.05$\mu\textrm{g}$/$m^3$이었다. 본 연구에서 측정된 실외 공기 내의 클로로포름 농도는 해외의 이전 연구들에서 보고된 값들과 동등하거나 작게 나타났다. 전형적인 한 시간 수영동안 흡기되는 클로로포름 흡취량은 일인다 25.9$\mu\textrm{g}$ 으로 추산되었고, 이는 70Kg의 성인 남자를 기준으로 하여 0.37$\mu\textrm{g}$/Kg 에 해당되는 흡취량이다. 반면에, 일인이 하루에, 실외 공기 흡입으로 인한 클로로포름의 흡취량은 5.6$\mu\textrm{g}$ 으로 추산되었고, 이는 동일한 성인 남자를 기준으로 할 때, 0.08$\mu\textrm{g}$/Kg/day 에 해당한다.

Chloroform present in the swimming water disinfected with sodium hypochlorite is released to the air of swimming pools. The air chloroform concentrations were measured in two swimming pools A and B which applied both sodium hypochlorite a:d ozone. Thew mean concentrations are 28.0 $\mu\textrm{g}$/m3 and 33.6 $\mu\textrm{g}$/m3in the swimming pools A and B, respectively. On the other hand, the mean water chloroform concentrations in the swimming pools A and B were 23.9 $\mu\textrm{g}$/l and 19.5 $\mu\textrm{g}$/l, respectively. The air chloroform concentrations were lower in the swimming Bools A and B than those reported by previous studies abroad employed the swimming pools which applied sodium hypochlorite only for water disinfection. The water chloroform concentrations were also lower in this study than in the previous studies. The relationship between the air and water chloroform concentrations measured in this study was significant with p=0.002 and Rz=0.42. At similar time to the indoor air sampling, outdoor air samples were collected at two sites near each of the swimming Pools A and B. The mean outdoor air chloroform concentrations near the swiminE Pools A and B were 0.41 $\mu\textrm{g}$/m3 and 0.16 $\mu\textrm{g}$/m3, respectively. The outdoor air chloroform concentrations measured in this study were equal to or lower than those reported by previous studies abroad. 'rho chloroform dose inhaled for a typical one-hour swim was estimated to be 25.9 $\mu\textrm{g}$ per person, corresponding to a specific 0.37 $\mu\textrm{g}$/kg body weight for a reference 70 Kg male adult, while the inhalation dose of chloroform from the outdoor air was estimated to be 5.6 $\mu\textrm{g}$ per person per day, corresponding to a specific 0.08 $\mu\textrm{g}$/Kg/day for the same reference male adult.
