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.
