UNDERSTANDING THE ENVIRONMENTAL IMPACT OF DEHP

Di-(2-ethylhexyl) phthalate (DEHP) is a common toxic chemical additive used to make polyvinyl chloride (PVC) more flexible. PVC with DEHP is used in medical devices like IV bags and tubing, which can be made of up to 40% DEHP by weight.1

 

DEHP is colorless, odorless and scentless and can enter humans by breathing it in or physcial contact, and during medical procedures with IVs.2,3

Coming in contact with DEHP can have serious negative health effects in humans.3 Exposure to DEHP through medical devices isn't where the danger stops. When disposed of, DEHP continues to threaten the environment.

 

DEHP is used to make PVC that is used in medical products. It can spread to the surrounding air, water and soil where it does not break down easily. After use, PVC is rarely recycled. It is incinerated or sent to a landfill. Burning PVC releases DEHP into the air where it can be breathed in or it settles into the ground. In landfills, DEHP spreads to water and soil where it contaminates microorganisms. It poses a threat to animals and can enter our food chain.
