studying heavy metal concentration in the entrance water of the dialysis machine and its comparison with aami and eph standards

background: the presence of heavy metals in dialysis water which enters patients’ body through haemodialysis can cause various problems such as acute poisoning, brain damage, osteoarthritis etc. therefore, applying the standards for dialysis water is indispensable. this study was carried out to determine the heavy metals of the enterence water of dialysis machines and its comparison with aami and eph standards in the hospitals of qom province, iran. methods: this study was carried out on 45 samples of the enterence water of the dialysis machines. since there were three hospitals in qom having dialysis units, 15 samples were chosen from each of them. atomic absorption machine was used for analyzing the samples. findings: the mean and standard deviation of alominium, lead and cadmium were 4.29 ± 4.05, 2.84 ± 0.42, 0.53 ± 0.18 µg/l, respectively and zinc was 0.002 ± 0.01 mg/l. these amounts were lower than aami and eph standards. but in few cases these amounts were higher than the standard level. conclusion: the avegare heavy metals measured in these hospitals was lower than the standard level. in other words, patients are in better conditions in comparison with the side effects of the above mentioned factors.
