The Centers for Disease Control and Prevention (CDC) published the Fourth National Report on Human Exposure to Environmental Chemicals, updated tables (NHANES) in March, 2013. The updated report contains updated tables on 117 chemicals and 34 new chemicals. Amongst them are data on phthalate metabolites, including the metabolites of benzylbutyl pththalate (BBP), di-isobutyl phthalate (DiBP), dibutyl phthalate (DBP), dicyclohexyl phthalate (DCHP), diethyl phthalate (DEP), di-2-ethylhexyl phthalate (DEHP), di-isodecyl phthalate (DiDP), di-isononyl phthalate (DiNP), Dimethyl phthalate (DMP) and di-n-octyl phthalate (DOP). Mono-isobutyl and mono-n-butyl phthalates, metabolites of DiBP, DBP and BBP were previously measured together. BBP, DCHP and DiNP are authorized as indirect food additives in the U.S.. In Europe, BBP, DBP, DEHP, DIDP and DiNP are authorized for plastic food contact materials.
