Abstract

Background and Objectives: Kidney patients in each dialysis cycle are exposed to extremely large volume of water, which is in direct contact with the patient’s blood. Hence, the occurrence of any type of contamination in the water used can be very toxic to patients. Thus, quality of water plays an important role in patient well-being. The aim of our study was to investigate the quality of water used for hemodialysis in Kashan Akhavan hospital.
Materials and Methods: This cross-sectional descriptive study was conducted on water quality used for hemodialysis in Kashan Akhavan hospital during Oct.-Nov., 2011. During the study a total of 26 water samples were taken from the raw water and inlet of hemodialysis instrument. Collected water samples were analysed for Heterotrophic plate count, residual chlorine, pH , K+, SO42- , Na+, F- ,Ca2+ , mg2+ ,No3- , Hg+ , Cd2+, Cr6+, Zn2+, Cu2+, Se2+ ,Co2+,Ag +and As2+ according to the standard methods for water and wastewater examination.
Results: Our results showed that the concentration of copper, zinc, cadmium, lead, chromium, and silver were 0.4, 0.6, 0.07, 0.05, 0.08, and 0.04 µgL-1 respectively. In addition, concentration of the chemical elements and heavy metals did not exceed the standard level in any cases. Moreover, no microbial contamination was observed in the samples analyzed.
Conclusion: Based on the results obtained, all water quality parameters in hemodialysis ward of Kashan Akhavan Hospital were compatible with AAMI (Association for the Advancement of Medical Instrumentation) water quality Standards and no health risk threatens the kidney patients.

Abstract
Background and Objective: Street dust is an important factor in urban pollution which consists of soil, particulate matters and heavy metals. At present, over half of the world’s population lives in urban areas. Therefore, this study aimed to investigate health risks of heavy metals in street dusts in Zahedan.
Materials and Methods: The samples of street dust were collected in Zahedan. After preparation, the samples, were injected to ICP-MS for determination the amount of Hg and Cu. According to the measured concentrations, Hazard quotient (HQ) and hazard index (HI) were calculated to evaluate the health risk assessment.
Results: Results showed that Hazard quotient for both Hg and Cu was less than 1 for children and adult. HQ for Hg and Cu was in order of HQingestion >HQdermal >HQinhalation> HQvapour for adults and HQvapour > HQingestion > HQdermal > HQinhalation  for children. HI was also less than 1.
Conclusion: The value of HQ showed that inhalation of mercury vapor and ingestion were the main routes of exposure to Hg for children and adults. The non-carcinogenic risk was within the safe value (HI <1) in this study.
