Evidence for PBDE-mediated effects from human studies in systems other than the developing nervous system, such as in cancer development, is inconclusive or non-existent. [11] Particularly for the potential effects of PBDEs on the developing fetus, research has focused on the health status of mothers and gestational age of the infant. [15]
Decabromodiphenyl ether (also referred to as decaBDE, DBDE, BDE-209) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs). It was commercialised in the 1970s and was initially thought to be safe, [3] [4] but is now recognised as a hazardous and persistent pollutant.
Pentabromodiphenyl ether (also known as pentabromodiphenyl oxide) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs). ). Because of their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention, a treaty to control and phase out major persistent organic polluta
Exposure to the coplanar stereoisomer 3,3',4,4',5,5'-hexabromobiphenyl (but not the non-coplanar stereoisomer) in genetically susceptible mice is known to cause immunotoxicity and disorders related to the central nervous system, and even at doses as low as 2.5 mg/kg, excess neonatal fatalities are observed (LD 50 is from 5–10 mg/kg).

Environmental toxicants and fetal development is the impact of different toxic substances from the environment on the development of the fetus.This article deals with potential adverse effects of environmental toxicants on the prenatal development of both the embryo or fetus, as well as pregnancy complications.
A new Clean Label Project report suggests some protein powders contain heavy metals lead and cadmium. See which ones are safe here, plus what an expert advises.
Humans and wildlife are rarely exposed to solitary contaminants, but rather to complex mixtures of potentially harmful compounds. Dioxins and DLCs are no exception. [ 3 ] This is important to consider when assessing toxicity because the effects of chemicals in a mixture are often different from when acting alone.
Risks Posed by Obesity in Cats. In the US, about 40% of the cat population is obese or overweight. Overweight cats have from 10 to 20% excess fat, and obese cats are 20 to 30% over their normal ...
