It is important to carry out research on heavy metal in fish body. The specific aims and targets of this research are: Want to know the metal content of Cadmium (Cd) in Ricefield eels (Monopterus albus) which comes from Rawa Taliwang Lake. The specific benefit is to protect consumers who consume fish from heavy metal contamination. The research was carried out at Rawa Taliwang Lake, namely in an area that is submerged in water. There are 2 research stations, namely in the eastern and western parts of the lake. Data collection method was carried out using traps (Bubu). Four Ricefield eel samples were taken at each station. Next, the rice eel samples were put into a plastic bag and then stored in a sample box. The research samples were then analyzed at the Mataram Uviversity analytical laboratory and at Environmental Laboratory of the Environmental and forestry services West Nusa Tenggara Province. The data analysis method is carried out by taking the tissues from the Ricefield eel muscles, and then analyzed for Cd heavy metal content by using Atomic Absorption Spectrophotometer. Measurement of heavy metals in Ricefield eel tissue was carried out by adding concentrated HNO3 and HClO4 , heated at a temperature of 60-70ºC for 2-3 hours until the solution was clear. Samples are ready to be measured with AAS using an air-acetylene flame. The conclusion of this research is that the content of Cd heavy metal in Ricefield Eels (Monopterus albus) originating from Rawa Taliwang Lake ranges from 2.55 - 4.01 mg/kg (ppm).
... Numerous studies have been conducted on metal pollution in various marine organisms in Turkish waters (Topçuoğlu et al. 2004(Topçuoğlu et al. , 2010Kayhan et al. 2007Kayhan et al. , 2016Türkmen 2011;Balkıs et al. 2012Balkıs et al. , 2013Erdem et al. 2015;Mülayim and Balkıs 2015;Özden and Tunçer 2015;Güner et al. 2016;Korkmaz et al. 2017;Durmus et al. 2018;Bat et al. 2019Bat et al. , 2023Duyar and Bilgin 2019;Türksönmez and Diler 2019;Yağcı 2019;Bayrakli 2021;Erguden et al. 2021;Kılıç et al. 2021;Köker et al. 2021;Yildirim et al. 2022;Acarlı et al. 2023;Koçbaş et al. 2023).

The aim of this study was to investigate the accumulation of elements (Se, As, Hg, Cr, Cd, Pb, Cu, Zn, Ni, Mn, Al, Fe, Co and V) in some marine organisms [Eriphia verrucosa (Forskål, 1775), Solea solea (Linnaeus, 1758), Mytilus galloprovincialis Lamarck, 1819, and Ulva lactuca Linnaeus, 1753] collected from the northern Sea of Marmara (Büyükçekmece, Silivri, Tekirdağ, and Şarköy) in 2019. For this purpose, element accumulation was measured using ICP-MS (Inductively Couple Plasma-Mass Spectrometer). The lowest and highest element concentrations in marine organisms are Fe (0.00 –7499.78 µg g⁻¹ dw); Pb (0.00–31.12 µg g⁻¹ dw); Cd (0.00–9.93 µg g⁻¹ dw); Cu (2.98–775.63 µg g⁻¹ dw); Cr (0.24–26.19 µg g⁻¹ dw); Mn (1.53–427.60 µg g⁻¹ dw); Al (0.00– 13,788.4 µg g⁻¹ dw); Ni (0.00–56.26 µg g⁻¹ dw); Hg (0.03–3.37 µg g⁻¹ dw); Zn (0.00–1554.23 µg g⁻¹ dw); As (0.00– 1.84 µg g⁻¹ dw); Se (0.00–0.04 µg g⁻¹ dw); V (0.13–72.54 µg g⁻¹ dw); and Co (0.00–10.98 µg g⁻¹ dw), respectively. According to these element values, Pb, Cd and Hg values were found to be higher in mussels than in crabs and exceeded the limits of the Turkish Food Codex. This study shows that more caution should be exercised when consuming marine organisms that exceed the limits of the Turkish Food Codex.
... The effects of this pollution on seafood have been examined in studies, and arsenic, cadmium, lead, mercury, and zinc levels in different species of seafood caught in the Sea of Marmara were found to be above the safe upper limits [22][23][24][25]. In a study conducted as part of this project, the levels of arsenic, cadmium, chromium, and lead in seafood caught in the Sea of Marmara were found to be above permissible limits [26]. In two recent studies on various species of fish in the Sea of Marmara, the levels of many toxic metals were found to be above the safe limits [27,28]. ...
Toxic chemicals from polluted seas can enter the human body through seafood consumption and cause health problems. The aim of this study was to evaluate the levels of selected heavy metals and trace elements among fishermen who frequently consumed seafood and controls who consumed seafood less frequently in four provinces on the shores of the Sea of Marmara, which is heavily polluted by industrial activities. Fourteen elements (antimony, arsenic, cadmium, chromium, copper, iron, lead, manganese, mercury, nickel, selenium, strontium, vanadium, and zinc) were analyzed in hair samples using the inductively coupled plasma-mass spectrometer method. Levels of arsenic (0.147 ± 0.067 µg/g vs. 0.129 ± 0.070 µg/g, p = 0.025), chromium (0.327 ± 0.096 µg/g vs. 0.269 ± 0.116 µg/g, p < 0.01), nickel (0.469 ± 0.339 µg/g vs. 0.403 ± 0.368 µg/g, p = 0.015), strontium (1.987 ± 1.241 µg/g vs. 1.468 ± 1.190 µg/g, p < 0.01), and zinc (103.3 ± 43.1 µg/g vs. 92.7 ± 37.4 µg/g, p = 0.047) were higher in the fisherman group than in the control group. No difference was found between the groups in terms of other elements. The findings suggest that heavy metal-trace element contamination in the Sea of Marmara may increase the exposure levels of individuals to some chemicals through seafood consumption.
... Cadmium is implicated in carcinogenic diseases (Rakib et al., 2021). Permissible amounts of cadmium in fish are 0.05, 1.4 and 0.5 mg/kg according to Turkish Fisheries Laws and Regulations (TKB) (Köker et al., 2021), EPA (EPA, 1989) and WHO (WHO, 1989), respectively. In the present study, the cadmium levels of the groups were found to be close to each other, and moreover, their levels were found tobe quite low and below the indicated limits (Table 1). ...
... It moves in nature due to atmospheric convection (Bosch et al., 2016). Permissible amounts of lead in fish are 0.3 and 0.5 mg / kg according to TKB (Köker et al., 2021) and WHO (WHO, 1989), respectively. In the present study, the differences in lead levels of the groups were not significant (P ˃ 0.05), and all of them were found to be below the indicated limits. ...
... Mercury is a heavy metal that does not naturally exist in living organisms (Köker et al., 2021), and it is mentioned to affect the human neurological system (Rakib et al., 2021). Permissible amounts of mercury in fish are0.5 and 0.5 mg / kg according to TKB (Köker et al., 2021) and WHO (WHO, 1989), respectively. ...
Pangasius hypophthalmus (panga fish) is farmed in the Mekong River (Vietnam), which is known as a polluted river, and exported to many countries. The present study aimed to determine heavy metal levels in frozen panga fillets imported from Vietnam as well as the risks of heavy metals to human health. Panga fillets belonging to four brands were bought from three supermarkets in Adana city, Turkey, and heavy metals (As, Cd, Hg, Pb, Ni, Cu, Mn and Co) were analyzed. To analyze the potential risks to human health, EWI (estimated weekly intake), THQ (target hazard quotient), and CR (lifetime cancer risk) values were calculated to assess the potential risks to consumer health of the metal content in panga fillets. The health risk assessment values were calculated for children and adults according to the frequency of consumption once, three and seven times a week. The results revealed that the presence of heavy metals in the studied panga fillets was below permissible limits indicated by WHO (World Health Organization), EPA (United States Environmental Protection Agency) and TKB (Turkish Fisheries Laws and Regulations). The EWI, THQ or ∑ THQ and CR values were below PTWI (provisional tolerable weekly intake), 1 and 10-5, respectively. Remarkably, the highest values of the EWI/PTWI ratio and THQs were found for children.
... In fact, few researchers sought to examine and assess the bioaccumulation of toxic elements, such as arsenic (As), chromium (Cr), cadmium (Cd), and lead (Pb), in these aquatic animals (Fernández-Trujillo et al., 2021;Ramon et al., 2021;Solgi and Mirmohammadvali, 2021;Yang et al., 2021). In general, the bioconcentration of toxic elements in aquatic animals is associated with the environment and food chain (Köker et al., 2021). Previously, fish was reported to absorb toxic elements by ingesting particulate matter suspended in the water (Varol et al., 2017). ...
Crayfish, carp, and crab threaten the consumer’s health due to the enrichment of the toxic elements. The concentration of the toxic elements (As, Cr, Cd, and Pb) in these aquatics was less investigated simultaneously in situ. In this study, the toxic elements in these aquatics from the same site of Hanchuan, Hubei Province, China were measured by ICP-MS to assess the enrichment of the four toxic elements in them and the health risk to the consumer. The results showed that the concentrations of these elements in muscle were lower than those in hepatopancreas/ liver, except for Cr in crayfish. Furthermore, the concentrations of Cd in the hepatopancreas of crayfish and crab exceeded the standards of China and the European Union. Accordingly, the hepatopancreas of crayfish and crab are not recommended for consumption. The estimated daily intake of these elements in the muscle of crayfish, carp, and crab did not exceed the provisional tolerable daily intakes, the corresponding target hazard quotient (THQ), and the cancer risk (CR) values for As were lower than 1 and 1 × 10–6, respectively. However, the accumulated consumption of the muscle of the three freshwater catches could result in a significant increase in the total THQ value. The total ingestion of the muscle of these catches should be limited. Collectively, these findings may renew interest in food safety and the health risk to humans owing to the consumption of freshwater catches.
... It has a unique stratification feature in which the surface layer is composed of the low salinity water of the Black Sea, and the bottom layer comprised the high salinity water of the Mediterranean Sea, and there is an active flow between these water bodies through the Bosphorus to Dardanelles (Orhon et al. 2021). Due to the heavy pollution which is a result of excessive urbanization and industrial activities, the water quality of the Marmara Sea has been affected negatively (Köker et al. 2021;Orhon et al. 2021). The quality varies among different regions in which the parts under anthropogenic and industrial pressure have poor to bad ecological status (Taşkın et al. 2020) due to high nutrient and organic carbon inputs from its drainage basin and large inputs from the Black Sea (Orhon et al. 1994). ...
This prospective study was aimed to explore the bacterial diversity of marine mucilage developed in the Marmara Sea and the North Aegean Sea by metabarcoding. For this purpose, mucilage samples were collected from five different sampling locations, and the bacterial community structure was analyzed by 16S rRNA gene amplicon sequencing. The results highlighted a diverse bacterial community dominated by Proteobacteria and Bacteroidetes species. A negative and significant correlation between pH level and Campylobacterales, Clostridiales, and Vibronales abundances was detected, while a strong positive correlation was determined between total phosphorus (TP) and Campylobacterales. Results revealed that the bacterial community in the mucilage samples was predominated by particle-attached species preferring high-nutrient concentrations. This is the first study evaluating the bacterial diversity in a mucilage outbreak using a metabarcoding approach. Its results may contribute to this growing area of research and provide a database for further studies.
... However, certain metals (such as Cd, Pb, Hg) have no known nutritional or beneficial effects on human health (Varol et al., 2017). Trace metals in fish can be transferred to human tissues, thereby posing potential health risks, particularly in sensitive populations (e.g., pregnant and nursing women, infants, and children) and coastal residents who consume large amounts of seafood (Liu et al., 2018;Hao et al., 2019;Koker et al., 2020). Diet is one of the important ways of human exposure to pollutants. ...
Due to their toxicity, non-biodegradability, and biological amplification in the food chain, heavy metal accumulation in humans via the consumption of fishes has become a problem. In this study, we analyzed the concentrations of six trace metals (Cd, Cr, Cu, Ni, Pb, Zn) in 12 marine fish species collected from Liaodong Bay, China, from 2015 to 2020, to understand the pollution status of the bay and evaluate the impact of fish consumption on human health. In addition, 5 fish species with the potential to serve as bioindicators of metal contamination were identified. In general, the average concentrations were Zn > Pb ≈ Cr > Ni ≈ Cu > Cd. There were significant differences in the concentrations in the muscle tissues of fish with different feeding strategies. The total target hazard quotient values of some fish were greater than 1 in 2015, suggesting that people were susceptible to high health risks. The year 2017 had the lowest values, which suggests that metal pollution in Liaodong Bay may have been decreasing at that time. Monitoring of metal concentrations in marine fish from Liaodong Bay warrants more study.
... Cd is a toxic heavy metal that is found in soil, water, seafood, and vegetables (Dennis et al. 2020;Gemeda et al. 2020;Koker et al. 2020;Orisakwe et al. 2015;Zhao et al. 2016). ...
Previous studies have determined the effects of exposure to certain heavy metals on cardiovascular disease (CVD); however, the association between cadmium exposure and CVD in adults remains unclear. The relationship between serum levels of cadmium and the risk of CVD was studied by analyzing available data from 38,223 different participants of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2016. After adjusting for all covariates, we found that higher serum cadmium concentrations were positively related to both the overall risk of CVD (odds ratio (OR): 1.45; 95% confidence interval (CI): 1.22, 1.72; p for trend <0.001) and the risks of its subtypes, including congestive heart failure, coronary heart disease, heart attack, and stroke. Elevated cadmium levels were associated with increased levels of lipids and inflammatory factors, including blood triglycerides, total cholesterol, white blood cells (WBCs), and C-reactive protein (CRP). Our study provided epidemiological evidence that cadmium may increase the risk of CVD by elevating blood lipids and inflammation.
