“…Contaminant metals can cause several problems in humans, and the contamination of bivalve mollusks with different concentrations of heavy metals can be dangerous, namely lead, cadmium and mercury. They can accumulate high concentrations from water, and from the sediments and they have a wide bioaccumulation range of heavy metals depending on the species [33][34][35].…”

Bivalve mollusks are an important resource due to their socioeconomic value and to the historical and genetic value of some species. Two nationally important oyster species-Portuguese oyster (Crassostrea angulata) and Japanese oyster (Crassostrea gigas) from distinctive areas in Portugal were studied to evaluate their sanitary status. Oysters were sampled from four different sites in Portugal. Oysters collected from Japanese oyster populations were cultivated in a strong ocean-influenced environment and Portuguese oyster populations were cultivated in wild-beds. The histopathological examination of both oyster species revealed the presence of parasites in gills, mantle epithelium, digestive gland tubules and connective tissue, with a moderate prevalence. In both populations was observed hemocytosis in the connective tissue, edema and metaplasia in the digestive gland and tissues necrosis. In wild populations from Sado and Mira estuaries the prevalence of mud blisters and gill lesions were higher than from populations produced on 0.50 m tables from mudflats. Biosecurity measures and diagnostic techniques are fundamental to control pathogenic agents, including the identification of pathogens at an early stage in their life cycles. This will prevent diseases and improve pathogen reduction on transport of animals from different countries and regions to new production areas to avoid the transmission of diseases.

“…Many studies have shown the high correlation between trace metal contents in sediment and in benthic organisms. Nour [7] studied on the contents of Fe, Mn, Cu, Zn, Pb, Ni, Cd, and Co in molluscan shells and associated surface sediments on the Gulf of Aqaba and Red Sea coasts, Egypt, and found that metal bioaccumulation of molluscan species was consistent with the enrichment factors for sediments. In another study, significant correlation of Cd, Cu, Pb, and Zn in sediments and oysters (Saccostrea cucullata) collected from Qeshm Island, Persian Gulf, Iran, was also demonstrated [36].…”

“…Several analytical methods are used for determining trace metal element contents in seafood. Most studies use atomic absorption spectrometry (AAS) for analyzing trace metal elements in seafood, such as the determination of Cr, Mn, Cu, Zn, As, Cd, Hg, and Fe in fish and crustacean samples in Bangladesh [5] or the study of Cd, Pb, and Hg in fish and seafood products in Bosnia and Herzegonia [6] or Fe, Mn, Cu, Zn, Pb, Ni, Cd, and Co in molluscan shells in the Gulf of Aqaba and Red Sea coasts, Egypt [7]. Another method, inductively coupled plasma-mass spectrometry (ICP-MS), is also utilized for analyzing different trace metal elements in edible fish from Atlantic Coast of Muanda, Congo [8], or in shrimp and shellfish in South Korea [9].…”

Fisheries and aquaculture production in the coastal zone of Vietnam contribute significantly to the national economy. However, seafood quality and safety, especially in terms of metal contents, are of increasing concern, for both domestic and international markets. This paper presents the results of an investigation in some trace metal elements (iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), arsenic (As), cadmium (Cd), and mercury (Hg)) concentrations in some fishes, crustaceans, and molluscs in the coastal zone of the Red River (in the Ba Lat estuary in Thai Binh and Nam Dinh provinces) during four sampling campaigns in 2020. All samples were treated by a green sample preparation using microwave digestion and then analyzed by inductively coupled plasma-mass spectrometry (ICP-MS). The results showed that the trace metal element concentrations in fish, crustacean, and mollusc samples decreased in the following order: Fe > Zn > Mn > Cu > As > Cd ∼ Hg. In more details, the ranges of trace metal elements in seafood samples were 13.13–202.73; 7.63–82.71; 0.48–22.73; 0.72–15.58; 0.18–5.12; 0.001–1.114; and 0.001–0.923 mg·kg−1 for Fe, Zn, Mn, Cu, As, Cd, and Hg, respectively. The research results contribute to the dataset of the seafood (both fishery and aquacultural seafood) quality in the Red River coastal zone. Although the mean values of different trace metal elements observed in this study were lower than the allowed values of Vietnam’s or European’s threshold for food safety, some high concentrations were detected. The survey results suggest the need to expand the monitoring scope (frequency of monitoring, number of samples, and observed variables) for obtaining a fully comprehensive assessment of seafood quality in this region. Our results also indicate that it is necessary to manage water quality in coastal areas, especially where aquaculture activities are carried out.

“…AS well as many of the heavy metals are present within the sediment composition in the form of major components, where the heavy metals and pollutants can be accumulated in sediments. Sediments can expulsion those pollutants to the water environment, especially when the water is of low concentration of these elements due to the exchange reactions, and those reactions increase with the increase in temperature, in addition to the effect of water flow speed and the small size of sediments, in general, the increase in the concentrations of heavy metals causes severe physiological damage to the organisms, which often leads to their death (Morel et al, 1991;Fernandes et al, 2008;Li et al, 2020;Nour, 2020). In the current study, the recording of Uranium concentrations in the Shatt al-Arab water during the spring and summer seasons in comparison to the absence of any concentration during the winter and autumn seasons,it may be due to the large bodies of water that entered from Iranian lands in the spring of 2019 that entered the Shatt al-Arab via the Sweib River passing through the Hawizehmarsh, which may contain part of the contaminated war remnants.…”

The current study included two sites in the middle part of Shatt Al-Arab-Southern Iraq (Al-Ashar and Al-Deir sites), the concentrations of trace elements which represented by Uranium, Arsenic, Beryllium and Vanadium were measured in water and sediments of four seasons from autumn 2018 to summer 2019 . The concentrations of trace elements showed variations at the level of significance in the water and sediments, Uranium recorded its highest concentration in the study water (6.1 µg/l) at the spring of Al-Deir site. While its highest concentrations in sediments reached (2.4 µg/g) at Al-Ashar site, moreover the highest concentration of Arsenic in water was (4.2 µg/l) at autumn of Al-Deir site and (6.1 µg/g) for sediments at Al-Ashar site ,as well as the concentration of Beryllium was below the detection limit (BDL) in water , while its highest concentration in sediments was recorded (1.1µg/g) as well as the highest concentration of Vanadium was (8.4 µg / l) in water and (87µg/g) in sediments.
