“…3). The predominance of BDE47 has been reported in previous assessments on PBDEs in aquatic organisms [32,33]. Brominated diphenyl ether-154's predominance over BDE153 and that of BDE100 over BDE99 in fish have also been reported in previous studies [19,34].…”

Legacy pollutants, polychlorinated biphenyls (PCBs), dichlorodiphenyl trichloroethane and its metabolites (DDTs), and some emerging organhalogen pollutants, such as polybrominated diphenyl ethers (PBDEs), hexabromobenzene (HBB), pentabromotoluene (PBT), 2,3,4,5,6-pentabromoethyl benzene (PBEB), 1,2-bis (2,4,6-tribromophenoxy) ethane (BTBPE), and dechlorane plus (DP), were detected in an aquatic food chain (invertebrates and fish) from an e-waste recycling region in South China. Polychlorinated biphenyls, DDTs, PBDEs, and HBB were detected in more than 90% of the samples, with respective concentrations ranging from not detected (ND)-32,000 ng/g lipid weight, ND-850 ng/g lipid weight, 8 to 1,300 ng/g lipid weight, and 0.28 to 240 ng/g lipid weight. Pentabromotoluene, PBEB, BTBPE, and DP were also quantifiable in collected samples with a concentration range of ND-40 ng/g lipid weight. The elevated levels of PCBs and PBDEs in the organisms, compared with those in non-e-waste regions in South China, suggest that these two kinds of pollutants derived mainly from e-waste recycling practices. Hexabromobenzene was significantly correlated with PBDEs, implying that HBB come from the release of e-waste along with PBDEs and/or the pyrolysis of BDE209. Most of the compounds whose trophic magnification factor (TMF) could be calculated were found to biomagnify (TMF > 1). Hexabromobenzene was also found, for the first time, to biomagnify in the present food web, with a TMF of 2.1.

“…As expected, among main species used for human food herring and eel show the highest levels [98; 99]. The catch area may also play a role, as shown by high levels in brown trout fillets from Lake Mjøsa, a highly contaminated spot in Norway [100]. In highly contaminated fish species or populations, the levels of the sum of indicator PBDEs may be over 300-400 µg/kg fresh weight [98; 100].…”

Sustainability, Security and Safety in the Feed-to-Fish Chain: Focus on Toxic Contamination

Abstract:The paper discusses the issue of feed ingredients in aquaculture as a telling example of implementation of a sustainable food safety strategy, aimed at protecting the health of next generation, under the One Health paradigm. Finfish and fishery products are a main nutrition security component as a valuable source of animal protein, particularly in developing countries. In addition, they are a critical source of essential oligo-nutrients, such as polyunsaturated fatty acids (PUFAs) and iodine. Production and consumption of fish has greatly increased in the last decade, mostly due to the growth of aquaculture. While the demand for aquaculture products continues to increase, there is the need to address consumers' concerns related to the nutritional quality and safety. In fact, both wild and farmed finfish can represent a significant source of exposure to contaminants for the consumer: noticeably, caught and farmed fish have a comparable content of nutrients and contaminants. Aquaculture feeds made of fish meal and fish oil are the main vehicle for transfer of environmental pollutants to farmed fish. The main fish contaminants (e.g., methylmercury, PCBs, PBDE) can bioaccumulate and affect development in humans. Feed ingredients as well fish species have a different liability to contamination depending, e.g., on the lipophilicity of the specific chemicals. Up-to-date risk-benefit assessments show that high intake of fish may lead to an undesirable intake of pollutants which is not sufficiently balanced by the concurrent intake of protective nutrients, such as PUFA. The use of vegetable-based feed ingredients in aquaculture has been explored from the standpoints of economic sustainability and fish productivity to a greater extent than from those of food safety and nutritional value. Available data show that vegetable oils can significantly modulate the lipid profile in fish flesh, depending on the oil and fish species. The use of vegetable ingredients can drastically reduce the accumulation of the main contaminants in fish; likewise the presence of other "unconventional" contaminants (e.g. PAHs) and the nutritional value of fish flesh could deserve more attention in the assessment of novel aquaculture feeds.

“…The United States consumed the largest quantity of PCBs (46% of the total global consumption), followed by Russia (7.9%), Germany (7.1%), Japan (4.1%), France (4.1%), and Canada (3.1%), which consistently corresponds to the residual levels of PCBs in aquatic products from these countries (Supplemental Data, Table S3). In contrast, the highest PBDE level was found in freshwater fish samples from Lake Mjøsa in Norway, probably due to the release of PBDEs into the water from a textile manufacturer in the town of Lillehammer [45]. Globally, the levels of OCPs in mussel samples collected from the coast of the Egyptian Red Sea were significantly higher than those from other regions, which may be attributed to the use of large amounts of OCPs in this region [46].…”

Abstract-The concentration levels of typical persistent organic pollutants such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs) including dioxin-like PCBs (DL-PCBs) and non-dioxin-like PCBs, organochlorine pesticides (OCPs), and polybrominated diphenyl ethers (PBDEs) in global aquatic products from major producing countries were summarized. Daily intakes of these compounds via consumption of various aquatic products for global consumers were also estimated based on available literature data. Risk assessment based upon existing criteria for OCPs and PBDEs shows that there is minimal risk to global consumers from consumption of aquatic products, with the exception of products from specific regions located around known heavy-point sources. Exposure to dioxins through consumption of aquatic products, excluding marine fish, is also in the range of the acceptable level, lower than 4 pg World Health Organization toxic equivalent (WHO-TEQ)/kg bw/d; however, dioxin intake via marine fish may cause hazards to human health, especially for Europeans. Regarding PCBs, there is cancer risk for global consumers via consumption of aquatic products, especially marine fish, based on cancer and noncancer hazard ratio assessment. Generally, European consumers have higher exposure levels of PCDD/Fs and DL-PCBs, while Americans and Asians have relatively higher exposure levels of OCPs and PCBs. In contrast, all global populations are found to have lower exposure levels of PBDEs, which may be attributed to its relatively shorter history of use compared with PCBs and OCPs. Finally, the estimated total amounts of PCBs, OCPs, and PBDEs stored in global aquatic products constitute only a small portion of the total amount that has been used, and the majority obviously occurs in other environmental media or even remains in commercial products.
