'Phthalates': Kelley et al. Respond

摘要

We appreciate Carter's review of our article (Kelley et al. 2012) and his further clarifi cation of the chemistry across this class of compounds. In the "Results" of our article, we specifically noted the use of ortho-phtha-lates (DBP and DEP), which were often found to be used in combination with the phthalate polymers he discussed in his letter [cellulose acetate phthalate (CAP), hypro-mellose phthalate (HMP), and polyvinyl acetate phthalate (PVAP)]. We believe that we appropriately distinguished the difference between the ortho-phthalates and the poly mers, specifically noting that the polymers have "no known toxicity."
