ABSTRACT
Objective:
To investigate the concentration level of chloroform in the water of swimming pool in Baoan District of Shenzhen City,and determine the risk factors.Methods:
During May and July,2019,a total of 110 water samples from 40 swimming pools were collected in Xin’an subdistrict of Bao’an District for the examination of chloroform routine indicators. In addition, 38 pipe water samples were collected for the examination of chloroform and free residual chlorine.Results:
The concentration of chloroform in the swimming pools was determined to be (43.400±27.802) μg/L with the median of 37.343 μg/L. Chloroform was correlated positively with total bacterial count(P<0.05),turbidity, free chlorine residual, and PH value(P<0.01).Conclusion:
The disinfection quality of swimming pool water in Bao’an District remains low. It is necessary to determine the risk factors associated with chloroform in the swimming pool and further reduce the concentration level of disinfection by-products.
