... According to the Food and Agriculture Organization of the United Nations (2019), the fish production and supply in Asia were the highest in the world owing to the enormous demands for fish as the daily diet of Asians (Cheung et al. 2008). Therefore, consumption of fish exposed to EDCs may pose a great threat to human health (Jia et al. 2016). In addition, a chemical's capacity for bioaccumulation could be utilized to predict long-term negative consequences that were not always addressed by acute toxicity and short-term exposure tests (Nallani et al. 2012). ...
... In C. idella, the levels of estrogen DES in the muscle were significantly lower than those in the gills, which may be due to the passive exchange of contaminants between fish and the aquatic environment through the gills. In addition, the gill is an important site of interaction with contaminants because it is the first organ to be in contact with water and resuspended sediment particles (Jia et al. 2016). The results suggested that water exposure might be the main exposure route of DES to C. idella. ...
The presence of endocrine-disrupting chemicals (EDCs) in aquatic environments such as water, sediment, and sludge received more and more attention. However, the bioaccumulate properties of EDCs, particularly progestins and androgens, in various tissues of different wild freshwater fish species, as well as their effects on human health, have not been fully studied. The muscle, liver, and gills of three wild fish species obtained from the East Dongting Lake in southern China were examined for the presence of 19 EDCs (4 progestins, 5 androgens, 6 estrogens, and 4 phenols). Seventeen analytes were detected in all fish samples, and the concentrations of progestins, androgens, estrogens, and phenols ranged from ND–78.80 ng/g (wet weight, ww), ND–50.40 ng/g ww, ND–3573.82 ng/g ww, and ND–88.17 ng/g ww, respectively. The bioaccumulation of some EDCs in wild fish from East Dongting Lake was species-specific. Additionally, AND, EES, P4, and E2 were discovered in the liver at higher levels than in the muscle, suggesting that livers had a larger ability for enriching these EDCs than the muscle. Furthermore, the relationships between the fish sizes and the EDC concentrations indicated that total weight and length had a negligible impact on the bioaccumulation of EDCs in various fish species. Most importantly, the effects of EDCs on human health as a result of fish consumption were assessed. Although the estimated daily intakes (EDIs) of most EDCs were much lower compared with the corresponding acceptable daily intakes (ADIs) via consuming fish collected in this study, the EDI of EE2 in Silurus asotus was higher than the ADI of E2, indicating that Silurus asotus from East Dongting Lake should be eaten in moderation by local residents.
Graphical Abstract
... Based on feeding characteristics, fish can accumulate significant amounts of endocrine-disrupting compounds (such as pharmaceuticals) via oral and gill intake. However, because it is an important source of protein, fish consumed by humans pose a health risk if they are contaminated with these pollutants (Jia et al., 2016). Therefore, it is extremely important to determine the contents of such micropollutants in fish species. ...
The presence, bioconcentration, and health risk via seafood consumption of 11 pharmaceutical compounds belonging to different therapeutic groups (anti-inflammatory, antiepileptic, lipid regulators, and hormones) were investigated in the muscle tissues of fish and the meat of shrimp in the Sea of Marmara. Six biota species (Merlangius merlangus, Trachurus meditterraneus, Serranus hepatus, Pomatomus saltatrix, Parapenaeus longirostris, Spratus sprattus) were collected from the five stations in October and April 2019. Ultrasonic extraction method followed by solid phase extraction was used for extraction of pharmaceutical compounds from biota samples and then analyzed using high-performance liquid chromatography. Of the 11 compounds, 10 were detected in biota species. Ibuprofen was the most frequently detected pharmaceutical in the biota tissues at high concentrations (<3.0-1225 ng/g, dw). The other widely detected compounds were fenoprofen (<3.6-323 ng/g, dw), gemfibrozil (<3.2-480 ng/g, dw), 17α-ethynylestradiol (<2.0-462 ng/g, dw), and carbamazepine (<7.6-222 ng/g, dw). The bioconcentration factors of the selected pharmaceuticals calculated in various aquatic organisms ranged from 9 to 2324 L/kg. The estimated daily intakes of anti-inflammatories, antiepileptics, lipid regulators, and hormones via seafood consumption were 0.37-568, 1.1-324, 8.5-197, 3-340 ng/kg bw. Day, respectively. Based on hazard quotients, estrone, 17β-estradiol, and 17α-ethynylestradiol may pose a health risk to humans through the consumption of this seafood.
... Aquatic environments and living organisms in Turkey, like the rest of the world, are contaminated with toxic pollutants such as heavy metals, pesticides, and endocrine disruptors (Cucu et al., 2019;Esfahani et al., 2020;Jia et al., 2016;Nyantakyi et al., 2021;Yarsan and Yipel, 2013;Yipel and Yarsan, 2014). Because of their widespread use, toxicity, and resistance to biodegradation, as well as their accumulation and biomagnification in living beings in the food chain, heavy metals are significant among aquatic pollutants (Altınok-Yipel et al., 2022;Esfahani et al., 2020;Jia et al., 2016;Liu et al., 2019). ...

Heavy metal contamination of aquatic environments thus poses potential risks to regional ecology, humans, and other living things at the top of the food chain (Altınok- Yipel et al., 2022;Esfahani et al., 2020;Yarsan and Yipel, 2013). ...
... Using crustaceans and other aquatic organisms as bioindicators to investigate the level of heavy metal contamination in the environment is a common practice (Jia et al., 2016;Yarsan and Yipel, 2013;Yüzereroğlu et al., 2009). Moreover, human health risk assessments on aquatic organisms in the food chain are essential and current public health research topics (Baki et al., 2018;Ezemonye et al., 2019;Liu et al., 2019;Yu et al., 2020). ...
Contamination of the aquatic environment and living things with pollutants is increasing daily. Among these pollutants, heavy metals come to the forefront regarding toxicological and public health due to their widespread use, toxicity, and resistance to degradation, as well as accumulation and biomagnification in the food chain. The study aimed to determine the essential (Cr, Cu, Fe, Mn, Ni, Zn) and non-essential (As, Al, Cd, Pb) metal concentrations by ICP-OES of Metapenaeus monoceros, Penaeus japonicus, Penaeus semisulcatus (n=30) caught from the Northeastern Mediterranean, Iskenderun Bay. The concentration of Cd, Cr, Ni, and Pb were under LOD. The concentration (ppm) ranges were Al: 0.73-38.89, As: 2.18-9.68, Cu: 28.96-69.01, Fe: 7.85-241.36, Mn: 0.44-1.28, and Zn: 51.71-108.51 for all species. Except for the As concentrations, the differences between mean concentrations of metals in shrimp species were not statistically significant. When the results of the study are compared with the findings of other studies on shrimps caught from the Iskenderun Bay, it shows that Cd, Cr, Ni, and Pb contamination levels decreased, while Cu, Fe, and Zn contamination levels increased.

Due to the decline of the Aral Sea fishery and recent efforts to expand the fisheries sector in Kazakhstan for both local consumption and global export, there is a need sustain other fisheries in the area, including the Shardara Reservoir, which lies in the Syr Dara basin. Metals are present in the Syr Darya; yet, their impacts on fishery and consumer health remains unclear. Thus, the objectives of this study were to evaluate: 1) the potential impacts of metals on Syr Darya basin fish and 2) the human health risks posed by consumption of Shardara Reservoir fish. The health of the fishery was assessed by comparing surface water metal concentrations to maximum permissible concentrations (MPCs), calculating water quality index (WQI) and degree of contamination (Cd) values, and evaluating gene expression biomarker responses in wild-caught roach (Rutilus rutilus). To assess the risk to consumers, metal concentrations in roach were used to calculate hazard quotients (HQs) and hazard indices (HIs). Water concentrations of Cu, Fe, Mn, Se, Sr and V exceeded MPCs and all sites were classified as highly polluted based upon WQI and Cd values. This, along with site-specific differences in the expression of genes associated with xenobiotic metabolism and oxidative stress in roach, indicates potential risks to the fishery. Though all HQs and HIs were below 1 indicating a lack of significant risk to consumers, Pb levels in roach exceeded MPCs for safe consumption indicating a risk to consumers. Given the potential risks to the fishery and consumers, the development of pollution monitoring and management programs are warranted. The work presented here provides initial monitoring data that can be used to aid such efforts and also underscores the need to identify environmental stressors that may thwart the anticipated growth of fisheries in this region.
... Copper (Cu) is generated from mining, metal smelting, and refining, abandoned mines and waste disposal facilities, together with rock weathering. This element poses a threat to wetland ecosystems due to its persistence, bioaccumulation, and toxicity (Jia et al. 2016;Gabrielyan et al. 2018;Zhou et al. 2020). Indeed, mining activities have several profound implications whereby overall water quality of nearby aquatic ecosystems can be adversely affected (Asif and Chen 2016). ...
High levels of trace metals such as copper (Cu) can affect water quality and induce toxic effects on living organisms in aquatic ecosystems. This research assesses the potential capacity for Cu phytofiltration by three emergent macrophytes from Cu-contaminated sediments and water containing five concentrations of Cu (0, 50, 100, 150, and 200 µM). We conducted a greenhouse study using semi-hydroponic and hydroponic experimental conditions to simulate a natural wetland system. We selected three plant types that were collected in Quebec (Canada): native Typha latifolia, and native and, exotic Phragmites australis. Under semi-hydroponic, the responses indicated an almost 3-fold higher mean root Cu-accumulation from Cu-0 to Cu-Sediment (80.3-226.1 mg kg-1) and an 8.6-fold increase (122.2-1045.5 mg kg-1) for Cu-0 to Cu-200 µM under hydroponic conditions, resulting in Cu translocation < 1 and BCF >1 under both conditions. We found an inverse correlation between increasing doses of Cu with mean aboveground and belowground biomass together with height, and root length of selected plants under hydroponic conditions. Our results indicate that these wetland macrophytes could be useful in heavy-metal removal from Cu-contaminated sediments and Cu-enriched water.
... Rapana venosa accumulates a higher quantity of metals (e.g., Cd, Cr, Pb, Ni, Cu) than Mytilus galloprovincialis (Jitar et al. 2015). Several indices such as target hazard quotient (THQ), hazard index (HI), total THQ (TTHQ), and estimated daily intake of metals (EDI) are used to assess health risks (Yabanli and Alparslan 2015;Jia et al. 2016). The calculations of these indices rely on the reference doses (RfDo) of each element provided by USEPA (the United States Environmental Protection Agency) ( Barnes and Dourson 1988;Environmental Protection Agency 2002). ...
This study examined the level of metals, metalloids, non–metals, and mineral elements in the edible parts as well as in other organs of Rapana venosa, obtained from the Eastern Black Sea. The concentrations of Ba, Ca, Cr, Co, Cu, Fe, Ni, P, Mo, Se, Pb, Sr, and Zn within the organs showed significant variations. The operculum possessed significantly higher Ba, Co, Cr, Fe, Mo, Pb, and Se, while the hepatopancreas had higher Ca, Cu, Ni, P, Sr, and Zn concentrations. The target hazard quotient (THQ) and total THQ were < 1, indicating no potential health risk to consumers.
... In particular, it was observed that toxic element concentration in muscles (e.g., Cd and Ni) significantly decrease with the fish length for M. obtusidens. Other authors have reported similar results between fish size and accumulated element concentrations [68][69][70]. Meanwhile, a positive correlation of element concentration in the gills and fish size was frequently observed in this study. ...
The concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn (TE) in four juvenile fishes (Acestrorhynchus pantaneiro, Salminus brasiliensis, Brycon orbignyanus, and Megaleporinus obtusidens) and associated sediment water from the Lower Paraná River were measured. For muscle, gills, and liver fishes, the TE accumulation in the muscle, gills, and liver was evaluated. The TE concentration was measured by quadrupolar inductively coupled plasma mass spectrometry (Q-ICP-MS). Cadmium (0.25 ± 0.07 μg L⁻¹), Cu (3.00 ± 1.44 μg L⁻¹), Fe (612 ± 69 μg L⁻¹), and Pb (1.92 ± 1.20 μg L⁻¹) in water and As (4.1–6.9 μg g⁻¹), Cr (20.1–31.4 μg g⁻¹), Cu (10.7–19.2 μg g⁻¹), Mn (351.3–482.2 μg g⁻¹), and Ni (24.5 ± 10.9 μg g⁻¹) in sediments exceeded the guide values for the conservation of aquatic life. In general, muscle of omnivorous species (B. orbignyanus and M. obtusidens) showed higher values of elements than those of carnivorous species (A. pantaneiro and S. brasiliensis). However, TE concentrations varied with fish species and organs. Independently of the examined species, the highest concentrations of Cr and Pb were in the muscle and gills, respectively. Cadmium, Cu, and Fe concentrations were higher in the liver than in gills and muscle in all four fish species. These results were consistent with the tissue selectivity index analyzed. For the four species, major essential elements showed the highest accumulation. However, the accumulation of toxic elements in omnivorous fish was higher than in carnivorous fish. The individual pollution load index indicated that sediment was very polluted with As and Pb, but based on the combined ecological indexes, low elemental sediment pollution in the Espinillo Lake was revealed.
... Heavy metals are a broad class of pollutants and toxicologically distinguished from others by intensive uses, non-biodegradability, accumulation, and magnification in the food chain. Some of the most affected/ accumulated food chain members are aquatic animals and health risk assessment based on metal levels in the tissues of various fish species is a hot research topic [5][6][7]. Owners prefer the canned/pouched or homemade diets with fish and liver the most because they are more appetizing to cats. Yet, as demonstrated in previous studies, heavy metals accumulate in higher levels in aquatic organisms [5,8]. ...
The main aim of this study was to determine the levels of Al, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, and Zn in commercial canned and pouched cat foods (salmon, tuna, liver, fish, and other aquatic products) and assess the potential health risks to kitten (≤ 1 years old) and adult cats (≥ 1 years old) associated with the recommended average consumption rate of labels. The study was also aimed to adapt the health risk assessment method to animal health and to support clinical prevention and diagnosis. The detected levels of the metals were below the data from other studies, except the mean Fe in all and Pb levels in salmon and kitten foods. Target hazard quotient (THQ) and total target hazard quotient (TTHQ) values did not exceed 1. That means the studied metals do not pose a health risk for adult cats and kittens. Dietary Hg and Cd should also be considered in the differential diagnosis of cases with clinical or postmortem findings, especially regarding neurological, kidney, and liver tissues. In conclusion, although canned/pouched consumption does not pose a health risk with regard to metals, further studies of health risk assessment for other pollutants by this first adaptation method will be necessary.

... Os metais são encontrados naturalmente nos sedimentos devido aos processos de intemperismo e lixiviação, porém as atividades antropogênicas (lançamento de efluentes e dejetos de animais, deposição atmosférica, mineração, agrotóxicos e fertilizantes) vêm provocando alterações no perfil dessas espécies nos sedimentos (Jia et al., 2016;Rodríguez-Blanco et al., 2018;Zhang et al., 2020). ...
O Refúgio Biológico de Santa Helena (RBSH) é uma unidade de conservação banhada pelo reservatório de Itaipu, no oeste do Paraná, Brasil. Apesar de ser uma área protegida, seu entorno é passível de contaminação por diversas fontes antropogênicas, principalmente ligadas a agropecuária. Objetivo principal desse estudo foi determinar os teores e a biodisponibilidade dos íons metálicos (Cr, Cu, Pb, Zn, Fe e Cd) nos sedimentos do entorno do RBSH, por meio da estração sequencial de Tessier, no verão e outono de 2019, estações climáticas que apresentaram diferentes níveis de água do reservatório. As diferenças hidrológicas entre o verão e o outono promoveram um acúmulo de alguns íons metálicos nos sedimentos e a liberação de outros para a coluna da água de uma estação para a outra. Os maiores teores de íons metálicos nos sedimentos foram detectados na fração ligada aos óxidos e hidróxidos de Fe e Mn, independente da estação climática, provavelmente devido à origem basáltica dos solos da região. No entanto, nenhum dos íons metálicos ultrapassou o valor do PEL (nível de efeitos prováveis), indicando que apenas ocasionalmente são esperados efeitos adversos à biota. Os indicadores de qualidade dos sedimentos mostraram uma contaminação moderada por Cr e Pb, em virtude de contribuições antropogênicas. Metal speciation in surface sediments of a conservation unit: Biological Refuge of Santa Helena – Paraná A B S T R A C TThe Santa Helena Biological Refuge (RBSH) is a conservation unit bathed by the Itaipu reservoir, in western Paraná, Brazil. Despite being a protected area, its surroundings are susceptible to contamination by several anthropogenic sources, mainly linked to agriculture and livestock. The main objective of the study was to determine the levels and bioavailability of metal ions (Cr, Cu, Pb, Zn, Fe and Cd) in the sediments surrounding the RBSH, through the sequential Tessier extraction, in the summer and autumn of 2019, which different levels of water in the reservoir. The hydrological differences between summer and autumn promoted the accumulation of some metal ions in the sediments and the release of others to a column of water from one season to the next. The highest levels of metal ions in the sediments were detected in the fraction linked to the oxides and hydroxides of Fe and Mn, regardless of the climatic season, probably due to the basaltic origin of the soils in the region. However, none of the metal ions exceeded the PEL value (level of probable effects), indicating that only occasionally adverse effects to biota are expected. The differentiated sediment quality indicators show moderate contamination by Cr and Pb, due to anthropogenic contributions.Keyword: sediments, metal ions, speciation, sequential extraction
