“…The concentrations of PBDEs in the surface water were usually below 1 ng/L, due to their inherently hydrophobic property. In China, the occurrence of PBDEs in surface water has been investigated in the three major river systems Pearl River, Yellow River, and Yangtze River at mean concentrations of Σ 7 PBDE (excluding 209) up to 0.08 ng/L [ 24 ], 1.26 ng/L [ 25 ], and 6.44 ng/L [ 26 ], respectively. The concentrations of PBDEs in Chaohu Lake basin were situated between the above concentrations, but were lower than those in the water of e-waste dismantling areas [ 27 ].…”

Polybrominated diphenyl ethers (PBDEs) were extensively investigated in water, sediment, and biota samples collected from Chaohu Lake basin in China. The total concentrations of eight PBDEs (Σ8PBDEs) were in the ranges of 0.11–4.48 ng/L, 0.06–5.41 ng/g, and 0.02–1.50 ng/g dry weight (dw) in the water, sediment, and biota samples, respectively. The concentrations showed wide variations in the monitoring area, while the congener profiles in all the water, sediment, and biota samples were generally characterized by only a few compounds, such as BDE-47, BDE-99, and/or BDE-209. The spatial analysis depicted a decreasing trend of PBDEs from west to east Chaohu Lake, consistent with regional industrialization degree. The distributions of PBDE congeners in the biota samples were similar to the compositional profiles in the water, which were dominated by BDE-47 and/or BDE-99. Nevertheless, BDE-47 and BDE-153 in the brain tissue showed a higher accumulative potential than PBDEs in other tissues as well as the whole body, with 96% relative contribution of Σ8PBDEs. The noncarcinogenic risk values estimated for BDE-47, BDE-99, and BDE-153 indicated that the specific risk associated with the studied water and foodstuffs is limited. However, there is a potential mixture ecotoxicity at three trophic levels at some sampling points in the water, which should draw considerable attention.

“…After collection, water samples are filtered through a 0.45 μm pore size membrane and stored at 4 °C in brown glass bottles to minimise photolytic degradation or biodegradation of the compounds. Analysis is usually performed within 48 hours ( 12 , 15 , 19 , 20 , 32 ). The optimal volume required for analysis with gas chromatography (GC) coupled with tandem mass spectrometry (MS/MS) or with liquid chromatography (LC) coupled with MS/MS is from 0.250 mL to 1 L ( 2 , 13 , 15 , 19 , 31 , 32 ).…”

“…Additionally, if sediment cores are collected, they can be stratified by sediment depth to obtain data for targeted analytes at a certain time estimated from the sedimentation rate at a location. Sediments are usually stored at -20 °C until analysis ( 13 , 32 , 36 , 37 ).…”

“…During extraction of target compounds from wastewater, an emulsion can be formed, which further complicates the procedure ( 15 , 34 ). LLE most often uses dichloromethane, n -hexane, or a mixture of n -hexane and dichloromethane (1:1, v / v ) to extract PBDEs from natural and wastewater samples ( 15 , 32 ). Dichloromethane is also used to extract TBBPA and TBBPS from river, sea, and tap water ( 19 ).…”

Analysis of brominated flame retardants in the aquatic environment: a review

The most common and consequently analysed brominated flame retardants (BFRs) are polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), tetrabromobisphenol A (TBBPA), tetrabromobisphenol S (TBBPS), and hexabromocyclododecane (HBCD). As these persistent organic pollutants are widespread in the environment and have a number of harmful effects on human health, the production and use of most has been banned for several years. The aquatic environment is polluted by these compounds through their deposition from the atmosphere, sewage sludge, wastewater treatment plants, and landfills, and higher levels are found in areas with developed industry and agriculture and near landfills. Each compound also seems to show preference for specific compartments of the aquatic environment, i.e. water, sediment, or aquatic organisms, according to their physicochemical properties. The aim of this review was to take a closer look at the analysis of BFRs, as without reliable analysis we would not be able to determine their levels and distribution across the aquatic compartments and assess human exposure and health risks. Particularly worrying are the health risks associated with PBDEs in fish, whose levels generally exceed the permitted values.
