    Concentrations of Phthalate Metabolites in Milk, Urine

    The MAMA study is the first to evaluate phthalate concentrations in multiple body fluids from a convenience sample of lactating women in the United States at two time points, focusing on oxidative phthalate metabolites in serum, milk, and saliva and both oxidative and hydrolytic monoester metabolites in urine.

    Concentrations of Phthalate Metabolites in Milk, Urine

    Our data suggest that phthalate metabolites are most frequently detected in urine of lactating women and are less often detected in serum, milk, or saliva. Urinary phthalate concentrations reflect maternal exposure and do not represent the concentrations of oxidative metabolites in other body fluids, especially milk.

    Concentrations of phthalate metabolites in milk, urine

    Background: Phthalates are ubiquitous in the environment, but concentrations in multiple media from breast-feeding U.S. women have not been evaluated. Objectives: The objective of this study was to accurately measure and compare the concentrations of oxidative monoester phthalate metabolites in milk and surrogate fluids (serum, saliva, and urine) of 33 lactating North Carolina women.

    MECPP was detected in> 80 % of serum samples, but other metabolites were less common (3–22%). Seven of the 10 urinary metabolites were detectable in ≥ 85 % of samples. Monoethyl phthalate had the highest mean concentration in urine. Metabolite concentrations differed by body fluid (urine> serum> milk and saliva).

    Concentrations of phthalate metabolites in Australian urine

    MEP was the predominant phthalate metabolite, ranging from 34 to 330 ng/mL (median, 130 ng/mL) in the various urine pools. The median concentration of MEP in this study was similar to the level reported by Huang et al. (2014) in the US during 2001–2008 (~150 ng/mL), but higher than that in Canadian (49.1 ng/mL) (Saravanabhavan et al., 2013), and Chinese populations (62–77 ng/mL) (Guo et al

  • concentrations of phthalate metabolites in breast milk

    Concentrations of phthalate metabolites in breast milk

    Based on phthalate metabolite concentrations in breast milk, daily intake of metabolites for breast-fed infants was estimated using the following equation: Daily intake μg / kg b w ‐ day = M C μg / L × D B I mL / 1000 / body weight kg where MC is the breast milk concentration of a given metabolite, DBI is daily breast milk intake amount of

    Phthalate metabolites in urine from China, and implications

    In this study, 14 phthalate metabolites were analyzed in 183 urine samples collected in 2010 from Shanghai, Guangzhou, and Qiqihaer, China. Phthalate metabolites were found in all urine samples and their total concentrations ranged from 18.6 to 3160 ng/mL (median: 331 ng/mL).

    Because only urine lacks esterases, we analyzed it for the hydrolytic phthalate monoesters. Re s u l t s: We detected phthalate metabolites in few milk (< 10%) and saliva samples. MECPP was detected in> 80 % of serum samples, but other metabolites were less common (3–22%).

    Consistent with laboratory evidence, we observed inverse associations between urinary concentrations of several phthalate metabolites and BC and subsequent survival; however, these results should be interpreted with caution given that biospecimen collection among women with BC occurred after diagnos …
