Phthalate esters are added to
polyvinyl chloride (PVC) to make it flexible. Adipate, a
nonphthalate ester, is sometimes used as an alternate platicizer.
Both esters readily leach from PVC and are present in the
environment in relatively large amounts. Considered by many to
be endocrine disruptors, studies have linked phthalates to
reproductive problems in rats and damaged sexual development in
neonatal infants.
