LOD, limit of detection. All phthalates are creatinine standardized. aLow-molecular-weight (LMW) phthalates were monobutyl phthalate, monoethyl phthalate, and monoisobutyl phthalate. bHigh-molecular-weight (HMW) phthalates were monobenzyl phthalate, mono(2-ethylhexyl) phthalate, mono(2-ethyl-5-carboxypentyl) phthalate, mono-(2-ethyl-5-hydroxyhexyl) phthalate, mono-(2-ethyl-5-oxohexyl) phthalate, and mono-(3-carboxypropyl) phthalate. cDi(2-ethylhexyl) phthalate (DEHP) metabolites were mono(2-ethyl-5-carboxypentyl) phthalate, mono-(2-ethyl-5-hydroxyhexyl) phthalate, mono-(2-ethyl-5-oxohexyl) phthalate, and mono(2-ethylhexyl) phthalate. dDibutyl phthalate (DBP) metabolites were monobutyl phthalate and monoisobutyl phthalate.
