摘      要：Background:Until their phase-out between 2005 and 2013,polybrominated diphenyl ethers(PBDEs)were added to household products including furniture,rugs,and electronics to meet flammability *** brominated flame retardant(BFR)chemicals,including 2-ethylhexyl-2,3,4,5-tetrabromobenzoate(TBB)and bis(2-ethylhexyl)2,3,4,5-tetrabromophthalate(TBPH),which are components of the Firemaster 550®commercial mixture,are now being used to meet some flammability standards in *** objective of this analysis was to evaluate the extent to which mothers and their children living in New York City are exposed to PBDEs,TBB,and ***:We measured PBDEs,TBB,and TBPH using gas chromatography mass spectrometry in dust(n=25)and handwipe(n?11)samples collected between 2012 and 2013 from mothers and children living in New York *** defined dust as enriched if the proportional distribution for a given BFR exceeded two-thirds of the total BFR ***:We detected PBDEs and TBPH in 100%of dust and handwipe samples and TBB in 100%of dust samples and 95%of handwipe *** from approximately two-thirds of households was enriched for either PBDEs(n?9)or for TBB t TBPH(n=8).Overall,the median house dust concentration of TBB+TBPH(1318 ng/g dust)was higher than that of SPentaBDE(802 ng/g dust)and BDE-209(1171 ng/g dust).Children generally had higher BFR handwipe concentrations compared to mothers(SPentaBDE:73%,BDE-209:64%,TBB t TBPH:55%)and within households,BFR concentrations from paired maternalchild handwipes were highly *** mothers,we found a significant positive relation between house dust and handwipe BDE-209 and TBB t TBPH ***:PBDEs,TBB and TBPH are ubiquitous in house dust and handwipes in a sample of motherchild pairs residing in New York City.
