Quantitative Determination of Di (2-Ethylhexyl) Phthalate (DEHP) in Hemodialysis-Related Materials

Phthalates are founded in medical devices such as filters and dialysis tubes. Scientific evidence shows health disadvantages due to exposure to phthalates. In this study, level of Di (2-ethylhexyl) phthalate (DEHP) in Iranian hemodialysis-related materials was measured. Ten samples of Iranian dialysis tubes (five samples made by Supa Company and five samples made by Helal Ahmar Medical Devices Company) were randomly selected. The level of DEHP for each sample was calculated and registered by Gas chromatography- Mass spectrometry (GC-MS). The results of five samples for each company were added together separately and mean of concentrations for DEHP (ml per ml) was reported. Means of DEHP concentration for Supa and Helal Ahmar were 1.36±0.11 and 0.97±0.11 mg/ml, respectively. The maximum and minimum of concentration for Supa were 1.47 and 1.21 mg/ml, respectively. As for Helal Ahmar samples, the minimum and maximum of concentration were 1.13 and 0.83 mg/ml, respectively. The use of alternative medical products without phthalate can reduce exposure of patients to phthalates.
