After the PBDE Phase-Out: A Broad Suite of Flame Retardants in Repeat House Dust Samples from California
Analysis of dust collected in California homes in 2006 and 2011 for 62 FRs and organohalogens suggests that manufacturers continue to use hazardous chemicals and replace chemicals of concern with chemicals with uncharacterized toxicity.
Analytical developments and preliminary assessment of human exposure to organophosphate flame retardants from indoor dust.
Exposure of non-working and working adults to OPFRs appeared to be similar, but in specific work environments, exposure to some OP FRs (e.g. TDCPP) was increased by a factor >5 and the estimated body burdens were 1000 to 100 times below reference dose (RfD) values.
Polybrominated diphenyl ethers in domestic indoor dust from Canada, New Zealand, United Kingdom and United States.
Despite the commercial formulations of PBDEs never having been manufactured in, nor imported into New Zealand, their presence in dusts from that country suggests international trade in PBDE-containing goods is an important pathway effecting their global distribution.
Levels and profiles of organochlorines and flame retardants in car and house dust from Kuwait and Pakistan: implication for human exposure via dust ingestion.
Evaluating the occurrence of various organochlorines (OCs) and flame retardants (FRs) in dust from cars and houses of Pakistan and Kuwait found that relatively lower levels were observed in car and house dust from Pakistan than Kuwait, while levels of ∑PBDEs, ∑NBFRs and ∑PFRs were higher in car dust, while ∑OCPs and∑PCBs were higher than RfD values.
Occurrence of alternative flame retardants in indoor dust from New Zealand: indoor sources and human exposure assessment.
Although the estimated exposure is well below the corresponding reference doses (RfDs), caution is needed given the likely future increase in use of these FRs and the currently unknown contribution to human exposure by other pathways such as inhalation and diet.

We estimated human exposure to organohalogenated contaminants (OHCs), including organochlorine pesticides (OCPs), such as hexachlorocyclohexanes (HCHs), DDT and metabolites, hexachlorobenzene, and
Assessment of human exposure to indoor organic contaminants via dust ingestion in Pakistan.
The results showed that the levels of estimated exposure via dust ingestion for all chemicals were several orders of magnitude lower than their reference dose values or than those reported in studies from Belgium, China, Singapore, and the UK.
Brominated flame retardants in Belgian home-produced eggs: levels and contamination sources.
The similarity between profiles and seasonal variations in the concentrations of BFRs in soil and eggs indicate that soil is an important source, but not the sole source, for eggs laid by free-foraging chicken.
Country specific comparison for profile of chlorinated, brominated and phosphate organic contaminants in indoor dust. Case study for Eastern Romania, 2010.
The results of the present study evidence the existence of a multitude of chemical formulations in indoor dust, including organochlorine pesticides, polychlorinated biphenyls, and flame retardants, such as polybrominated diphenyl ethers, HBCDs, and novel brominated FRs.
Inter-species differences for polychlorinated biphenyls and polybrominated diphenyl ethers in marine top predators from the Southern North Sea: Part 1. Accumulation patterns in harbour seals and
A higher contribution of lower chlorinated and non-persistent congeners, such as CB 52, CB 95, CB 101, and CB 149, together with higher contributions of other PBDE congeners than BDE 47, indicated that harbour porpoises are unable to metabolize these compounds.
