(in Medical Dictionary)

Everybody is regularly exposed to low levels of DEHP. Some people can still be exposed to higher levels of DEHP by undergoing certain procedures. DEHP may be leaked from plastic medical devices and into any solutions that are in direct contact with it. The temperature and lipid content of liquids, as well as the time spent in contact with plastic, will affect the amount of DEHP released. Patients who are seriously ill may require multiple procedures. This exposes them to higher amounts of DEHP.
