What is HBCD used for?
The main use of HBCD is as a flame retardant in expanded polystyrene foam (EPS) and extruded polystyrene foam (XPS) (Weil and Levchik, 2009). EPS and XPS are used primarily for thermal insulation boards in the building and construction industry (Morose, 2006).
Does HBCD bioaccumulate?
This also suggests that bioaccumulation of HBCD was not affected by an increase in metabolic activities. Overall, the rapid excretion of HBCD from the gut and the consistently low body burden analysis in all diets over the duration of the experiment suggest that HBCD is not bioaccumulating in mealworm tissues.
How is HBCD made?
Hexabromocyclododecane (HBCD or HBCDD) is a brominated flame retardant. It consists of twelve carbon, eighteen hydrogen, and six bromine atoms tied to the ring. Its primary application is in extruded (XPS) and expanded (EPS) polystyrene foam that is used as thermal insulation in the building industry.
Is Hbcd banned?
The Stockholm Convention on Persistent Organic Pollutants has voted for a global ban of hexabromocyclododecane (HBCD), a common flame retardant in insulation, textiles, and electronics.
Is Hbcd safe?
HBCD will threaten health and environment for decades unless EPA acts. Hexabromocyclododecane (HBCD) is a toxic chemical that has been used as a flame retardant in foam building insulation and other products for many years.
What does highly branched cyclic dextrin do?
Nutrient claims include that HBCD can be used to help reach a demanding high-carbohydrate intake for the day, enhance nutrient absorption, enhance muscle nutrient delivery, and help optimize glycogen repletion.
Is HBCD banned?
Is highly branched cyclic dextrin bad for you?
The results of this study demonstrate that HBCD is digested to normal and safe products of carbohydrate digestion, and therefore, support the safety of HBCD for human consumption.
Does Hbcd spike insulin?
HBCD is considered a far superior source of carbs compared to other types of GI carbs like maltodextrin and dextrose as it provides a sustained increase in energy levels without causing spikes in the blood glucose and/or insulin levels.
Is cyclic dextrin safe?
Conclusion: Health Canada’s review of the information presented in support of the use of Cluster Dextrin®, CCD® (cyclic dextrin, highly branched) as a food ingredient concluded that there are no food safety concerns.
Does bottled water have PFAS?
The study, published in the journal Water Research and led by Johns Hopkins University researchers, detected PFAS substances in 39 out of more than 100 bottled waters tested, in some cases at levels deemed concerning by water quality experts.
How long do PFAS stay in your system?
Though PFAS linger in the human body, they do dissipate. Though they stick around for a long time, the body does eventually get rid of them. It takes about four years for the level of PFOA or PFOS to go down by half, even if no more is taken in, ATSDR reports. Certain types of PFAS leave the body faster.
What is HBCD?
HBCD is a brominated flame retardant found world-wide in the environment and wildlife. Human exposure is evidenced from its presence in breast milk, adipose tissue and blood.
What is a HBCD flame retardant?
HBCD is a brominated flame retardant found world-wide in the environment and wildlife. Human exposure is evidenced from its presence in breast milk, adipose tissue and blood. It bioaccumulates and biomagnifies in the food chain. It persists and is transported long distances in the environment, and highly toxic to aquatic organisms.
What is the new problem formulation for HBCD?
In June 2018, EPA released the problem formulation for HBCD which refined the scope of the risk evaluation by clarifying the chemical conditions of use that EPA expected to evaluate and describing how EPA expected to conduct the evaluation.
What is the status of the cyclic aliphatic bromide cluster (HBCD)?
The cyclic aliphatic bromide cluster (HBCD) is currently undergoing risk evaluation under the Toxic Substances Control Act (TSCA). EPA is evaluating HBCD because the 2016 amendments to TSCA directed EPA to pick its first ten chemicals for evaluation from the TSCA Work Plan, and HBCD is on the Work Plan.
