Introduction: According to high volumes of water used in hemodialysis, quality of water entering the dialysis machine is very important. The current study aims to analyze microbial and chemical quality of water used for hemodialysis in hospitals of Kashan city in 2019.
Materials and Methods: This descriptive cross-sectional study was performed on 54 water samples used in dialysis machines in hospitals of Kashan city during 3 months of the fall season in 2019. Microbial tests of the samples were done, and also heavy metals were assessed using inductively coupled plasma optical emission spectrometry. Statistical tests, sample t-test, and ANOVA were used to compare the mean results with standards.
Results: Based on the results, the mean concentrations of magnesium (Mg) (2.7 ± 2.22 mg/L), sulfate (13.09 ± 21.06 mg/L), sodium (Na) (17.27 ± 24.47 mg/L), and potassium (K) (0.09 ± 0.17 mg/L) in all samples were based on the standard levels. However, the mean concentrations of nitrate (3.22 ± 1.21 mg/L), aluminum (Al) (0.26 ± 0.16 mg/L), silver (Ag) (0.52 ± 0.85 mg/L), lead (Pb) (0.08 ± 0.13 mg/L), and zinc (Zn) (0.91 ± 0.71 mg/L) were above standard levels in all the samples. Thallium (Tl) ion was reported to be zero. Moreover, heterotrophic bacteria were not observed in any of the samples.
Conclusion: Given the high concentration of chemicals and heavy metals in dialysis machines water input, it is necessary to plan for periodic monitoring of water treatment systems and heavy metals and regular replacement of reverse osmosis filters.
