Abstract: The concentration of cyanuric acid, a by-product of chlorinated isocyanurates in the disinfection of swimming pool, would affect the efficiency of disinfection and had potential adverse effects on people's health when its concentration was too high. A total of 47 articles on the research and current status of cyanuric acid in swimming pool water published in Chinese and English in 1974-2016 were retrieved from databases, such as CNKI, Wanfang, CQVIP, PubMed, Web of Science and Science Direct. A brief description on the current contamination level of cyanuric acid in swimming pool water, its health effects on people, domestic and foreign standards for its control, the efficiency of disinfection and the technology for determination and control was given in this paper. Furthermore, the direction and prospection for future development was also proposed.
