Background & Objectives: Chemical quality of water entering the dialysis machine in hemodialysis patients is of great importance especially in terms of heavy metals. The study was performed on the concentration of heavy metals (cadmium, copper, chromium, lead and zinc) in water of dialysis machine in Teaching Hospital of North Khorasan University of Medical Sciences in 1394.

Material & Methods: Eighteen municipal water samples and 18 samples of effluent water from reverse osmosis systems of Imam Ali dialysis centers were analyzed. Association for the (advancement of medical instrumentation) AAMI and (Epidemiology and Public Health) EPH were compared.

Results: The mean concentrations of cadmium, copper, chromium, lead, and zinc were 0.47± 0.19, 0.1 ± 0.03, 0.016 ± 0.012, 2.72 ± 0.4, 0.03± 0.01, respectively.

Conclusion: The average concentration of heavy metals in the drinking water for Imam Ali hemodialysis machines comply with existing standards and therefore does not threaten the safety of dialysis patients.
