多溴联苯醚（pbdes）是一类环境中广泛存在的全球性 有机污染物 ，由于其具有环境持久性， 远距离传输 ，生物可 累积性 及对生物和人体具有毒害效应等特性，对其 环境问题 的研究已成为当前 环境科学 的一大热点。

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.

多溴二苯醚（英語： Polybrominated diphenyl ethers ，缩写PBDEs）是一类有机溴化合物，常用作阻燃剂。 和其它 有机溴阻燃剂 类似，多溴二苯醚已被广泛用于各种产品的防火，包括建筑材料、电子产品、家具、塑料、 聚氨酯 泡沫、纺织品等 [ 1 ] 。

2024年11月21日 · Polybrominated diphenyl ethers (PBDEs) include the commercial versions of pentabromodiphenyl ether (c-pentaBDE), octabromodiphenyl ether (c-octaBDE), and decabromodiphenyl ether (c-decaBDE). Each of these commercial products is a mixture composed of several PBDE congeners.

PBDEs are flame-retardant chemicals that were added to a variety of consumer products to make them difficult to burn. These substances are not single chemical compounds, but rather mixtures of several brominated substances. The entire family of PBDEs consists of 209 possible substances that are referred to as congeners.

2020年5月27日 · 多溴联苯醚(pbdes)是一种新型持久性有机污染物，在环境及生物体内普遍存在且污染呈增长趋势，并对动物及人类健康造成潜在的危害。 本文介绍了PBDEs的结构、性质、对环境的污染情况、分析方法等。

PBDEs are human-influenced chemicals utilized massively as flame retardants. They are environmentally persistent, not easily degraded, bioaccumulate in the biological tissue of organisms, and bio-magnify across the food web. They can travel over a long distance, with air and water being their possible transport media.

2024年2月1日 · Polybrominated diphenyl ethers (PBDEs) serve as brominated flame retardants which continue to receive considerable attention because of their persistence, bioaccumulation, and potential toxicity. Although PBDEs have been restricted and phased out, large amounts of commercial products containing PBDEs are still in use and discarded annually.

PBDEs are considered endocrine disrupting chemicals, which are synthetic chemicals that when absorbed into the body either mimic or block hormones and interfere with the body’s normal functions. This disruption can happen through altering normal hormone levels, halting or stimulating the production of hormones, or changing the way hormones ...

2022年5月15日 · Both bound and mobilised PBDEs enter the ocean with atmospheric deposition (including gaseous exchange for mobilised forms), river discharge and treated and untreated wastewater. Additionally, PBDEs may be associated with plastic products or structures that are directly used in or lost to the marine environment.
