Background and objective: Swimming pools being some of the popular sport centers are able to potentially receive some pollutants such as nasal secretions, saliva and urine and endanger the health of swimmers. The aim of this study was to determine the bacterial and fungal pollution of swimming pools in Karajcity and effect of some environmental factors on it. Materials and Method: In this study, 7 pools and 103 samples including water and environmental surfaces were evaluated with standard methods. Residual chlorine, pH, number of swimmers and temperatur were studied. SPSS statistical software (version 19) was used for data analysis and the P-value was ≤ 0.05. Results: research showed that the average of PH and residual chlorine was 7/5 & 2/20 ppm, correspondingly. 24/27% of samples were positive for one or more fungal contamination. Aspergillus spp were 65/71%, Candida spp 20%, Rodotrolla spp 2/86%, other filamentous fungi 8/57% and other yeast species 2/86%.MPN test in 93/4% and HPC test in 84/6% were in the standard range. Results of tests with carpet samples showed the highest contamination was in dressing room. statistical analysis indicated that there is a direct relationship between decrease of residual chlorine, increase of number of swimmers with increaseof contamination. Conclusion: Test results indicate the presence of bacterial and fungal contamination in water and equipment pools. It is proffered to use the filtration and chlorination systems and teaching people about compliance hygiene.

Background and objective: the role of swimming pools as a useful and interesting sport is obvious to everyone, which its curable aspect has been considered these days. On the other hand, we should not reject the possible threats of this sport. So, the purpose of this research is to consider the quality of swimming pools, Whirl pool and cool water basin in Tehran. Methods: in this descriptive- analytic inquiry which has been done in first six months of 1392, in 12, 13, 14 and 15 areas of Tehran municipality and within two parts, studied 27 active lidded swimming pools. At first stage, it has been got samples from all these pools and at the next stage, it has been got renewed samples after presenting suitable ways and instruction to the liable of swimming pools which have been polluted at first stage. All the stages of sampling, transferring to the lab and analyzing of samples from the aspects of remained free color quantity, PH, microbial contamination has done based on standard methods of water and sewer tests. Results: the results show the amount of remained free color at National standard limit of minimum 0 and maximum 4(1-3mg/L) in 48% of samples. 76/1% had standard pH(7.2-8) and also Heterotrophic bacteria of all samples were in a good situation. Conclusion: this study showed the most microbial contamination part was whirl pools and cool water basins in which the amount of remained free color was not on standard extent. Also, in renewed getting samples from pools which were contaminated at first stage of tests, all samples were lack of microbial contamination after considering necessary preparation by liable of swimming pools and giving structures by environmental hygiene inspectors of east hygiene center.
