Another important finding is the occurrence of very low levels or the absence of hydroxylated PBDE metabolites in the cats. In addition, the major OH-PBDE, 6-OH-BDE47, is likely of natural origin, probably ingested via cat food. The statistics indicate an association between elevated PBDE concentrations in the cats and FH. Find local businesses, view maps and get driving directions in Google Maps.

The average level was 96 ppb and 16 of the 40 women had at least 100 ppb of PBDEs in their milk. These levels were comparable to levels found in other studies in North America, but 20 to 40 times higher than levels found in Sweden and Japan (see related Flash animation ). Several polybrominated diphenyl ethers (PBDEs) have been identified as meeting the Section 73 criteria for persistence and/or bioaccumulation and inherent toxicity to non-human organisms and nominated for inclusion in a pilot phase for preparation of screening assessments under CEPA 1999.

Included in the water framework list of priority substances. See also.
Usually, PBDE levels in North America have been reported to be higher than those in Aside from their fire-retardant properties, PBDES are potent toxins that persist in the environment and bioaccumulate in the food chain and in human tissues. 3 Like PCBs, PBDEs are lipophilic and have been found in fish, bird eggs and marine mammals as well as in human milk, fat and blood.
PBDEs do not dissolve easily in water and bind strongly to soil or sediment particles. This reduces their mobility in soil, sediment, surface and groundwater, but increases their mobility in the

Medical Evaluation of PBDE exposure . PBDEs can be measured in human blood, body fat and breast milk for epidemiological studies. However, for the individual patient, obtaining PBDE levels are not accessible or useful clinical tests. They are prohibitively expensive and have no interpretable reference ranges for clinical outcomes. Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants. Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, and textiles.

多溴二苯醚. (PBDE) x x o o o o o o o. PBDEs, or polybrominated diphenyl ethers, are a class of fire retardant chemicals. As part of NOAA's Mussel Watch Program, PBDEs are one of 150 different contaminants that are continually monitored by periodically sampling bivalves and sediment at 300 coastal sites around the nation. treatment methods; and additional sources of information. This fact sheet provides basic information on PBDEs to site managers and other field personnel who may encounter these contaminants at cleanup sites. PBDEs have been used widely in the United States since the 1970s; however, there is growing concern about their persistence in the Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) belong to a class of chemicals that are added to certain manufactured products in order to reduce the chances that the products will catch on fire.
