The data suggest that levels of these organophosphate flame retardants are comparable, or in some cases greater than, levels of PBDEs in house dust, and warrant further studies to evaluate potential health effects from dust exposure, particularly for children.
Body mass index in relation to semen quality, sperm DNA integrity, and serum reproductive hormone levels among men attending an infertility clinic.
Distribution, variability, and predictors of urinary concentrations of phenols and parabens among pregnant women in Puerto Rico.
Positive associations between biomarker concentrations with self-reported use of liquid soap, sunscreen, lotion, BP-3 and parabens, and cosmetics can inform future epidemiology studies and strategies to reduce exposure to these chemicals or their precursors.
Relationship between Urinary Phthalate and Bisphenol A Concentrations and Serum Thyroid Measures in U.S. Adults and Adolescents from the National Health and Nutrition Examination Survey (NHANES)…
The results support previous reports of associations between phthalates—and possibly BPA—and altered thyroid hormones and the potential clinical and public health implications of these associations.
House Dust Concentrations of Organophosphate Flame Retardants in Relation to Hormone Levels and Semen Quality Parameters
OP flame retardants may be associated with altered hormone levels and decreased semen quality in men, and a suggestive inverse association between TDCPP and free androgen index became less evident in adjusted models.
DNA damage in human sperm is related to urinary levels of phthalate monoester and oxidative metabolites.
Sperm DNA damage was associated with MEP and with MEHP after adjusting for DEHP oxidative metabolites, which may serve as phenotypic markers of DEHP metabolism to 'less toxic' metabolites.
Altered Semen Quality in Relation to Urinary Concentrations of Phthalate Monoester and Oxidative Metabolites
The present study confirms previous results on the relationship of altered semen quality with exposure to MBP at general population levels and includes measurements of di(2-ethylhexyl) phthalate (DEHP) oxidative metabolites.

The results suggest that the most efficient exposure assessment strategy for a particular study may depend on the phthalates of interest, and a single urine sample was moderately predictive of each subject’s exposure over 3 months.
Temporal Variability and Predictors of Urinary Bisphenol A Concentrations in Men and Women
A nonsignificant increase in urinary BPA concentrations in women while pregnant is found compared with nonpregnant samples from the same women, and a single urine sample showed moderate sensitivity for predicting a subject’s tertile categorization.
Relationships between polybrominated diphenyl ether concentrations in house dust and serum.

Evidence that house dust is a primary exposure pathway of PBDEs is provided and the use of dust PBDE concentrations as a marker for exposure to PBDE congeners other than BDE 153 is supported.
