  • The assessment indicated that Canadians may be exposed to PBDEs from environmental sources (for example, air, water, household dust), food (including human breast milk), and products available to consumers that have been treated with mixtures of PBDEs (for example, televisions or computer casings).
  • This assessment took into consideration the results of human biomonitoring studies, which is the measurement of substances in blood, urine or breast milk. The presence of a substance in the body does not necessarily mean that it is causing harm. Harmful effects depend on the levels and the properties of the substances. The information on measured levels in humans is important to estimating exposure to Canadians.
  • PBDEs can be released to the environment throughout their lifecycle. This includes from the handling and manufacturing of the chemicals to use of the products which contain them.
  • At the time of the assessment, PBDEs were detected in all environmental media, as well as sewage biosolids.
  • The assessment also indicated that wildlife may be exposed from the consumption of prey containing elevated concentrations of PBDEs found in commercial mixtures.
  • High concentrations of PBDEs from commercial mixtures may also present a risk to organisms that live in the sediment.

In the past two decades, PBDEs have become widespread environmental pollutants, and have been detected in water, soil, air, dust, and animal and human tissues. Primary routes of exposure are diet (fish, meat, dairy products) and the indoor environment (dust). Of the 209 possible PBDE congeners, a number of tetra-, penta-, and hexaBDEs, and decaBDE, are commonly found in humans. Though most PBDEs have been banned or are being phased out, they are still persistent in the environment.

A large body of evidence demonstrates that human exposure to highly prevalent environmental chemicals with hormonal function may be closely associated with an increase in cancer risk. To deal with several possible mechanisms of endocrine-disrupting chemicals (EDCs), many experimental and epidemiological studies have been performed. EDCs are present in numerous places in environment, such as in food and water (through the use of pesticides) as well as in cosmetics, plastics, and other products used daily at home. Experimental models have been proposed to establish a link between exposure to EDCs and cancer development and to understand possible mechanisms of EDCs. Based on scientific papers published, EDCs were shown to produce a wide variety of endocrine-disruption effects, including developmental disorders, carcinogenicity, and mutagenicity in animal experiments. Moreover, the adverse effects of EDCs may include alterations in immunity, fertility, and neurobehavior.

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,[1] and textiles.

2) What are the health issues:
The health hazards of these chemicals have attracted increasing scrutiny, and they have been shown to reduce fertility in humans at levels found in households.[2] Because of their toxicity and persistence, the industrial production of some PBDEs is restricted under the Stockholm Convention, a treaty to control and phase out major persistent organic pollutants (POPs).]]> 2022-11-04 17:31:54 UTC https://padlet.com/hbanda/l6czgchw4u5pgto6/wish/2370457270 1) PBDEs are added to household materials in an attempt to make them less flammable. https://padlet.com/hbanda/l6czgchw4u5pgto6/wish/2370457593 2) PBDEs are less flame retardant than originally thought, and it turns out they are harmful to humans and animals when exposed tothem.]]> 2022-11-04 17:32:10 UTC https://padlet.com/hbanda/l6czgchw4u5pgto6/wish/2370457593 PBDEs https://padlet.com/hbanda/l6czgchw4u5pgto6/wish/2370457760 1.       The Pollutant Polybrominated diphenyl ethers (PBDEs) are a result from flame retardants in a number of applications, including textiles, plastics, wire insulation, and automobiles.

Finished products that may contain PBDEs are furniture foam padding; wire insulation; rugs, draperies, and upholstery; and plastic cabinets for televisions, personal computers, and small appliances. PBBs were used in the past, and one in particular, BB-153, has not been produced in the U.S. since the 1970’s.

These chemicals can get into the air, water, and soil during their manufacture; they can leak from products that contain them or escape when the products that contain them break down. They do not dissolve easily in water; they stick to particles and settle to the bottom of rivers or lakes. Some PBDEs can build up in certain fish and mammals when they eat contaminated food or water.

Certain PBDE congeners are persistent, bio accumulative, and toxic to both humans and the environment. The critical endpoint of concern for human health is neurobehavioral effects. Various PBDEs have also been studied for ecotoxicity in mammals, birds, fish, and invertebrates. In some cases, current levels of exposure for wildlife may be at or near adverse effect levels.

Triggers are things that can cause asthma symptoms, an episode or attack or make asthma worse. If you have asthma, you may react to just one trigger or you may find that several things act as triggers. Be sure to work with a doctor to identify triggers and develop a treatment plan that includes ways to reduce exposures to your asthma triggers. https://padlet.com/hbanda/l6czgchw4u5pgto6/wish/2370459913 2022-11-04 17:33:47 UTC https://padlet.com/hbanda/l6czgchw4u5pgto6/wish/2370459913 Polybrominated diphenyl ethers (PBDE) https://padlet.com/hbanda/l6czgchw4u5pgto6/wish/2370459933 What is its source?
Flame retardants (a mixture of several PBDE congeners) in a number of applications, including textiles, plastics, wire insulation, and automobiles

How does the pollutant impact public health?
Neurobehavioral toxicity for humans and ecotoxicity for animals such as birds, fish, invertebrates, etc.

PBDEs typically come from furniture foam padding; wire insulation; rugs, draperies, and upholstery; and plastic cabinets for televisions, personal computers, and small appliances. PBDEs are not chemically bound to plastics, foam, fabrics, or other products in which they are used, making them more likely to leach out of these products. People can be exposed to PBDEs and PBBs by eating contaminated foods, especially those with a high fat content, such as fatty fish. Another source of exposure results from breathing contaminated air or swallowing contaminated dust. Working in industries that make these chemicals or that make, repair, or recycle products containing these chemicals flame retardants can result in exposure. 
 
 
(2) How does the pollutant impact public health?
There is an impact in the form of neurobehavioral effects in mammals. In animal studies, these chemicals have shown some effects on the thyroid and liver, as well as on brain development. More research is needed to assess the human health effects of exposure to PBDEs and PBBs.

PBDEs are used as flame retardants (any compound or mixture added to a consumer product or building material to reduce the flammability and thus improve product safety). Their use is included in textiles, plastics, wire insulation, and automobiles. 

2. PBDEs are harmful because they are persistent, bioaccumulative, and toxic to both humans (neurobehavioral effects) and the environment (have been studied for ecotoxicity in mammals, birds, fish, and invertebrates, with at or near adverse effect levels). Exposure to flame retardants has been linked with a host of health problems including cancer, thyroid disease, decreased fertility, and lower IQ.
