Limited research exists on socioeconomic and racial/ethnic disparities in exposure to these compounds and their impact on executive functioning (EF) in early childhood. The present study examined independent and joint effects of income and race/ethnicity on flame retardant exposure in early childhood and investigated associations between flame retardant exposure and children&#039;s EF.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;METHODS: &lt;/strong&gt;This cross-sectional study used data from 349 preschool children recruited in Oregon. Children wore silicone wristband samplers for seven days, with exposures to 41 flame retardant compounds analyzed by gas chromatography mass spectrometry. We focused on exposure to 6 compounds (BDE 47, BDE 99, BDE100, TCPP, TDCPP, TPP) and two composite indices (ΣPBDE, ΣOPE). Wilcoxon rank-sum tests examined exposure differences by race/ethnicity and income (low income = below federal poverty level). Multiple linear regression models, nested within classrooms, assessed the association between PBDE and OPE exposure and EF, measured by the Head-Toes-Knees-Shoulders-Revised (HTKS-R) and Dimensional Change Card Sort (DCCS) tasks.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;RESULTS: &lt;/strong&gt;Children were 5.1 years old (SD = 0.3), 29.9% were from underserved racial/ethnic backgrounds, and 27.8% of families were low income. Compared with higher income families, children from low income families were exposed to 83.4% greater ΣPBDE exposures and 36% greater TDCPP exposures. There was no evidence of racial/ethnic disparities in PBDE or OPE exposures. Controlling for age, sex, income, race/ethnicity, and disability or cognitive delay, neither PBDE nor OPE exposures were consistently related to EF, but children from lower income families scored 28.6% lower on the HTKS-R, and children from underserved races/ethnicities scored 25.9% lower on the HTKS-R.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;CONCLUSIONS: &lt;/strong&gt;Our findings highlight persistent income disparities in PBDE exposures at a pivotal point in children&#039;s development, and reveal similar disparities in TDCPP exposures. Furthermore, socioeconomic disadvantage was more strongly associated with reduced EF than either PBDE or OPFR exposures. These findings underscore the need to address structural social inequities, and also highlight the need for greater representation of children from underserved backgrounds in research that seeks to characterize chemical and social exposures within neighborhood and preschool environments.&lt;/p&gt;

Exposure to endocrine-disrupting compounds with thyroid targets, such as flame retardants (FRs), may contribute to disease development. Silicone passive sampling devices, or pet tags, quantitatively assessed the bioavailable FR exposures of 78 cats (≥7 y) in New York and Oregon using gas chromatography-mass spectrometry. Pet tags were analyzed for 36 polybrominated diphenyl ethers, six organophosphate esters (OPEs), and two alternative brominated FRs. In nonhyperthyroid cats, serum free thyroxine (fT), total T (TT), total triiodothyronine, and thyroid-stimulating hormone concentrations were compared with FR concentrations. Tris(1,3-dichloro-2-isopropyl) phosphate (TDCIPP) concentrations were higher in hyperthyroid pet tags in comparison to nonhyperthyroid pet tags (adjusted odds ratio, &amp;lt; 0.07; Mantel-Cox, &amp;lt; 0.02). Higher TDCIPP concentrations were associated with air freshener use in comparison to no use ( &amp;lt; 0.01), residences built since 2005 compared to those pre-1989 ( &amp;lt; 0.002), and cats preferring to spend time on upholstered furniture in comparison to no preference ( &amp;lt; 0.05). Higher TDCIPP concentrations were associated with higher fT and TT concentrations ( &amp;lt; 0.05). This study provides proof-of-concept data for the use of silicone pet tags with companion animals and further indicates that bioavailable TDCIPP exposures are associated with feline hyperthyroidism.&lt;/p&gt;

Brominated diphenyl ethers (BDE) and organophosphate-based flame retardants (OPFRs) are associated with poorer neurocognitive functioning in children. Less is known, however, about the association between these classes of compounds and children&#039;s emotional and social behaviors. The objective of this study was to determine if flame retardant exposure was associated with measurable differences in social behaviors among children ages 3-5&amp;nbsp;years.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;METHODS: &lt;/strong&gt;We examined teacher-rated social behaviors measured using the Social Skills Improvement Rating Scale (SSIS) and personal exposure to flame retardants in children aged 3-5&amp;nbsp;years who attended preschool (n = 72). Silicone passive samplers worn for 7&amp;nbsp;days were used to assess personal exposure to 41 compounds using gas chromatography-mass spectrophotometer. These concentrations were then summed into total BDE and total OPFR exposure prior to natural log transformation. Separate generalized additive models were used to evaluate the relationship between seven subscales of the SSIS and lnΣBDE or lnΣOPFR adjusting for other age, sex, adverse social experiences, and family context.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;RESULTS: &lt;/strong&gt;All children were exposed to a mixture of flame retardant compounds. We observed a dose dependent relationship between lnΣOPFR and two subscales where children with higher exposures were rated by their preschool teachers as having less responsible behavior (p = 0.07) and more externalizing behavior problems (p = 0.03). Additionally, children with higher lnΣBDE exposure were rated by teachers as less assertive (p = 0.007).&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;CONCLUSIONS: &lt;/strong&gt;We observed a cross-sectional association between children&#039;s exposure to flame retardant compounds and teacher-rated social behaviors among preschool-aged children. Children with higher flame retardant exposures exhibited poorer social skills in three domains that play an important role in a child&#039;s ability to succeed academically and socially.&lt;/p&gt;
