In this study, 72 single-use medical products, grouped into four categories, namely, creams/liquids (n = 8), medical devices (n = 46; 15 of 46 labeled “di(2-ethylhexyl)phthalate (DEHP)-free”), first aid products (n = 13), and intravenous (IV) infusion/irrigation fluids (n = 5), were collected from an intensive care unit in a hospital in New York State in 2015 and analyzed for the migration of 10 phthalates in ethanol/water (1:1) mixture for 1 h. The total phthalate concentration (Σphthalates) leached from medical products ranged from 0.04 to 54,600 μg. DEHP was the major phthalate found in 99% of the samples analyzed, with the highest amount leached from respiratory support devices (median: 6560 μg). DEHP was also found at notable concentrations in products labeled as “DEHP-free”. Direct exposure to phthalates from the use of medical devices and first aid supplies and dermal intake from the use of creams/lotions were calculated. The highest DEHP exposure dose of 730 μg/kg bw/day was determined from the use of cannula for neonates. This is the first study to document the amount of phthalates leached from various medical supplies and associated exposures.
