“…To assess the relationship between PBDE exposure of Lake Sturgeon and TH production, linear regressions were performed with T 4 and T 3 concentrations in serum and logtransformed concentrations of PBDE congeners 47, 99, 100, 153, 154, and 209 in whole bodies of Lake Sturgeon. The congeners PBDE-47 and PBDE-99 were specifically examined because they are prevalent in aquatic ecosystems and are commonly detected in biota (Yu et al 2010;Wenning et al 2011). Additionally, a previous study by Arkoosh et al (2017) indicated that these congeners altered circulating TH concentrations in juvenile Chinook Salmon Oncorhynchus tshawytscha.…”

“…Specifically, CECs classified as PBDEs have been shown to impact the endocrine system and thyroid hormone (TH) production in fish species such as the Russian Sturgeon Acipenser gueldenstaedti, Fathead Minnow, and Zebrafish Danio rerio (Boiko and Grigor'yan 2002;Lema and Nevitt 2004;Legler 2008;Yu et al 2015), which may have implications for growth, reproduction, and survival of juvenile Lake Sturgeon A. fulvescens. Polybrominated diphenyl ethers are commonly used in industrial and consumer products, such as flame retardants, polyurethane foams, textiles, and resins (Wenning et al 2011). Although the industry has begun phasing out their use, the presence of PBDEs in the environment is a continuing concern (USEPA 2017) due to the use and disposal of existing products containing PBDE compounds.…”

“…Although the industry has begun phasing out their use, the presence of PBDEs in the environment is a continuing concern (USEPA 2017) due to the use and disposal of existing products containing PBDE compounds. Because PBDEs are fat soluble, are persistent in the environment, and can bioaccumulate (Wenning et al 2011;USEPA 2017), an understanding of their effects on fish biology is important in order to better manage and conserve species.…”

Contaminants of emerging concern (CECs) are ubiquitous throughout aquatic environments. Previous research has shown that CECs can have detrimental effects on fish biology, potentially leading to population impacts. Specifically, polybrominated diphenyl ethers (PBDEs), a class of CECs, have been shown to alter thyroid hormones in fish, which can impact development, endocrine system functioning, and possibly imprinting. These impacts can lead to reproductive effects and population declines, which have serious implications for species of conservation priority, such as the Lake Sturgeon Acipenser fulvescens. To assess the effects of CECs and PBDEs, Lake Sturgeon were evaluated at rearing facilities within the Great Lakes basin during 2017-2018 to determine (1) whether exposure to CECs and PBDEs differs between facility locations and (2) whether changes in whole-body PBDE concentrations correlate with changes in thyroid hormones (triiodothyronine [T 3 ] and thyroxine [T 4 ]), which could indicate impacts to imprinting. Exposure to CECs and PBDEs differed among sites. The CECs that were detected in water across all sites included atrazine, hexachlorobenzene, N,N-diethyl-meta-toluamide (DEET), desethylatrazine, erythromycin, and metformin, with the highest concentrations (except for DEET) measured at the Maumee River (Ohio) streamside rearing facility.We detected PBDEs in every sample of water, food, and Lake Sturgeon eggs and whole bodies, and there were no differences in lipid-normalized total PBDE concentrations in whole bodies across sites. Concentrations of total PBDE and the PBDE congeners 47, 99, 100, 153, 154, and 209 in fish tissues did not correlate with serum T 3 and T 4 levels, indicating that observed concentrations were unlikely to negatively impact Lake Sturgeon rearing for the biological endpoints assessed. Overall, this study exemplifies a cautionary tale since CECs and PBDEs were identified throughout Lake Sturgeon habitat and in hatchery food sources. Fisheries managers should be aware of the potential for CEC and PBDE impacts even though current observed levels do not seem to be impacting Lake Sturgeon rearing success.

“…Biotransformation is highly variable, and it depends on the enzymatic activities of a specific animal. Although benthic invertebrates, particularly the annelids, have relatively low biotransformation capability, biotransformation still affects their bioaccumulation potential [4][5][6]. Because DDT, DDD, and DDE have similar hydrophobicity and affinity for sediment organic carbon, they typically co-occur in sediment [7].…”

“…Because DDT, DDD, and DDE have similar hydrophobicity and affinity for sediment organic carbon, they typically co-occur in sediment [7]. In addition, DDT can metabolize to DDD and/or DDE in biota, and this biotransformation process is species-specific [2,6]. Consequently, body residues of DDD and DDE may have originated either from the direct uptake of these sediment-associated metabolites or from in vivo biotransformation from DDT.…”

Biotransformation of dichlorodiphenyltrichloroethane in the benthic polychaete, Nereis succinea: Quantitative estimation by analyzing the partitioning of chemicals between gut fluid and lipid

Biotransformation plays an important role in the bioaccumulation and toxicity of a chemical in biota. Dichlorodiphenyltrichloroethane (DDT) commonly co-occurs with its metabolites (dichlorodiphenyldichloroethane [DDD] and dichlorodiphenyldichloroethylene [DDE]), in the environment; thus it is a challenge to accurately quantify the biotransformation rates of DDT and distinguish the sources of the accumulated metabolites in an organism. The present study describes a method developed to quantitatively analyze the biotransformation of p,p'-DDT in the benthic polychaete, Nereis succinea. The lugworms were exposed to sediments spiked with DDT at various concentrations for 28 d. Degradation of DDT to DDD and DDE occurred in sediments during the aging period, and approximately two-thirds of the DDT remained in the sediment. To calculate the biotransformation rates, residues of individual compounds measured in the bioaccumulation testing (after biotransformation) were compared with residues predicted by analyzing the partitioning of the parent and metabolite compounds between gut fluid and tissue lipid (before biotransformation). The results suggest that sediment ingestion rates decreased when DDT concentrations in sediment increased. Extensive biotransformation of DDT occurred in N. succinea, with 86% of DDT being metabolized to DDD and <2% being transformed to DDE. Of the DDD that accumulated in the lugworms, approximately 70% was the result of DDT biotransformation, and the remaining 30% was from direct uptake of sediment-associated DDD. In addition, the biotransformation was not dependent on bulk sediment concentrations, but rather on bioaccessible concentrations of the chemicals in sediment, which were quantified by gut fluid extraction. The newly established method improved the accuracy of prediction of the bioaccumulation and toxicity of DDTs.
