“…Relatively high biotransport fluxes were also observed for BDE 209 in Dianchi Lake (2.522 mg/km 2 /d) and the Yangtze River Estuary (1.731 mg/km 2 /d), PCB 138 in Dianchi Lake (0.322 mg/km 2 /d), and p,p ′-DDE in Dianchi Lake (1.089 mg/km 2 /d). Though the atmospheric deposition fluxes of these pollutants in Dianchi Lake are not available, the lower atmospheric deposition flux of BDE 209 (0.45 mg/km 2 /d in central China), PCB 138 (0.103 mg/km 2 /d in Yangtze River Estuary), and p,p ′-DDE (0.164 mg/km 2 /d in Guangzhou) than those of this paper were reported in developed regions of China. − The results indicate that migratory birds can serve as vital vectors of bioaccumulative pollutants and transport pollutants from stopovers and wintering habitats to other sites.…”

Levels of heavy metals and organic contaminants in main waters from China were reviewed from literature data to assess the ecological risks of pollutants for wetland birds and the biotransport of pollutants mediated by migratory wetland birds. Cr, Cu, and Pb and polycyclic aromatic hydrocarbons (PAHs) dominated in sediments, with higher concentrations in rivers and estuaries than in lakes and seas. Plants are the main dietary sources of less hydrophobic organic pollutants, while sediment is the primary source of more hydrophobic PAHs in birds. The hazard index (HI) for birds was mainly contributed by mercury (Hg) and polybrominated diphenyl ethers (PBDEs) and ranked as piscivore > omnivore > herbivore. Pollutant exposure risks to birds depend on the biomagnification potential of pollutants, food items of birds, and pollution levels in habitats. Migratory birds are important biovectors of persistent and bioaccumulative pollutants that may serve as a vital geochemical cycling process in addition to atmospheric deposition. This study provided a comprehensive overview of water environment pollution in China and the potential risks for high trophic level wetland birds in aquatic ecosystems. The results also identified the pollution hotspots of wetland birds and habitats, which provide new insights into bird conservation and biodiversity protection.

“…The PBDEs concentrations in the spring water samples were higher than in the summer samples. This could be attributed to atmospheric wet deposition and also the heavy runoff of foulsmelling stormwater on the sampling day [47,48]. With spring being a rainy (wet) season in South Africa and windy, both wet and dry depositions are possible, especially in the coastal environment.…”

Occurrence and Risk Assessment of Polybrominated Diphenyl Ethers in Surface Water and Sediment of Nahoon River Estuary, South Africa

The concentrations, potential sources, and compositional profile of PBDEs in the surface water and sediment of Nahoon Estuary, East London, South Africa, were investigated with solid-phase extraction and ultra-sonication, respectively, followed by gas-chromatography-electron capture detection. The seasonal range of the contaminants’ concentrations in water and sediment samples in spring season were ∑PBDE 329 ± 48.3 ng/L (25.32–785 ng/L) and ∑PBDE 4.19 ± 0.35 ng/g dw (1.91–6.57 ng/g), but ∑PBDE 62.1 ± 1.50 ng/L (30.1–110 ng/L) and ∑PBDE 65.4 ± 15.9 ng/g dw (1.98–235 ng/g) in summer, respectively. NH1 (first sampling point) was the most contaminated site with PBDE in the Estuary. The potential source of pollution is attributed to the stormwater runoff from a creek emptying directly into the Estuary. This study’s dominant PBDE congener is BDE-17, ranging from below detection limit to 247 ng/L and 0.14–32.1 ng/g in water and sediment samples, respectively. Most detected at all the sites were BDE-17, 47, 66, and 100. Most BDE-153 and 183 are found in sediment in agreement with the fact that higher brominated congeners of PBDE adsorb to solid materials. There was no correlation between the congeners and organic carbon and organic matter. However, the human health risk assessment conducted revealed that the PBDE concentration detected in the estuary poses a low eco-toxicological risk. Nevertheless, constant monitoring should be ensured to see that the river remains safe for the users, as it serves as a form of recreation to the public and a catchment to some neighbourhoods.

“…day) in the present study was 2 or 3 order of magnitude higher than those determined in sites remote from densely populated or heavily industrialized area: Arellano et al (2014) reported mean depositional fluxes of PBDE 209 ranging from 2.4 to 5.4 ng/m 2 .day measured in four high mountain regions of Europe; a total deposition flux of 0.45 ng/m 2 . day was observed in an isolated mountain area located in central China (Zhan et al, 2019); and, in a rural region of Sweden, the median deposition level of PBDE 209 was 4.3 ng/m 2 .day (ter Schure et al, 2004). The deposition fluxes of PBDE 209 observed during our campaign were also higher than those measured in suburban and urban districts of Izmir (Turkey) (average levels: 49.4 and 107.5 ng/m 2 .day respectively) (Cetin and Odabasi, 2007) or in the vicinity of a municipal solid waste treatment plant (median deposition flux: 63.8 ng/m 2 .day) and an asphalt industry (median deposition flux: 14.7 ng/m 2 .day) located in Sweden (ter Schure et al, 2004).…”

In Belgium, 16 shredding facilities manage annually tens of thousands tons of wastes from different origins (endof-life vehicles, electronic waste, electrical transformers, …). These materials contain hazardous persistent organic pollutants such as polychlorinated dibenzo-dioxins/furans (PCDD/Fs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). The shredding process promotes the production and the emission of dust contaminated by these compounds. The objective of this study is to measure the concentrations of PCDD/ Fs, PCBs and PBDEs in fallout dust collected in the vicinity of 3 shredding plants located in Wallonia (French speaking part of Belgium). Samples were collected by using Owen gauges and pollutant levels were measured by GC-MS. The median deposition levels measured for ∑ PCDD/Fs, ∑ dioxin-like PCBs, 5 × ∑ 6 DIN PCBs and PBDE 209 were 1.9 pg TEQ/m 2 .day, 4.4 pg TEQ/m 2 .day, 246.5 ng/m 2 .day and 253.8 ng/m 2 .day, respectively. These levels represent high concentrations compared to those observed in most of the remote, rural and urban areas studied around the world and were similar to those measured in other heavily industrialized districts. Consequently, the health effects of this high exposure to pollutants among workers and residents in the vicinity of these shredding facilities are of concern.
