Abstract:
Objective To describe the change of chloroform concentration in swimming pool water and to study the influence factors. Methods The swimming pool water samples were collected in 10 public swimming pools and were determined and evaluated according to the Sanitary Standard for Drinking Water(2001), GB/T 17220-1998, GB/T18204.9-2000, GB9667-1997. Results Chloroform concentration in 21 water samples was from lower than 0.006 to 0.184 mg/L, the median was 0.120 mg/L. In the present study, chloroform concentration was correlated positively with turbidity, CODMn, tetrachloride, the free chlorine residual and pH. A negative correlation was found between chloroform concentration and coliform group. Chloroform concentration among the different swimming pools exhibited statistical significance. Conclusion Chloroform concentration in swimming pool water was significantly higher than that in tap water in Jiading, Shanghai. Change of chloroform is different among swimming pools. The increase of chloroform may be related to the pollutants and chlorination in swimming pool water.
