“…As indicated by MPI, the bioaccumulated metals were differentially distributed in the studied tissues with tendency to concentrate in the active metabolic organs either for long-term storage or excretion. This observation was in agreement with Omar et al (2014) who reported that the metabolically active tissues as liver and kidneys had high affinity to concentrate the greatest amount of most metals in their tissues. In contrast, the lowest metals bioaccumulation were observed in muscles (lowest MPI) and this may be related to the high fat-content in muscle tissues with low affinity to combine with metals in addition to the low metabolic activity of muscle (Uluturhan and Kucuksezgin, 2007).…”

“…Bioaccumulation of metals in the edible tissues is a useful tool for examining the biological responsibility of those metals that present at elevated levels other than assessment of public health risk (Bastami et al, 2015). In agreement with Omar et al (2014), although the HI values do not pose any health hazards for the normal consumers, the levels are likely to be greater for fish-dependent consumers in addition the risk may significantly increase when these tissues are collectively consumed. Risk avoidance should then focus on diminishing the amount of discharged metals, especially those with long half-life time, into the hot spot sites of river Nile.…”

This work aimed to assess the impact of Sabal drains (northern part of El-Minufiyah governorate, Egypt) on the metals load of river Nile. Four sites were selected to monitor the partitioning of metals in the aquatic components: reference site (site1); 20Km before Sabal drainage (site2); Sabal site (site3) and 20Km after Sabal drainage (site4). The maximum means of aqueous metals were observed at site3 in the following order (mg/l): Fe (0.76) >Mn (0.325) >Zn(0.07) >Pb (0.064) >Cu (0.041) >Cd (0.0035), while the trend is slightly different in sediments (mg/kg): Fe (527.9) >Mn (102.7) >Zn (17.65) >Cu (11.4) >Pb (1.26)>Cd (0.07). Tissue-specific patterns of metal accumulation in Oreochromis niloticus were observed. As indicated by the calculated metal pollution index and bioaccumulation factor, the tissues of liver, kidneys and gills were observed to be strong bioaccumulators compared to muscular tissues. Regarding the correlation study in site3, the bioaccumulated metals in most tissues showed homogenous-correlation with aqueous metals (r>0.5) and diverse-correlations with respect to sedimentary metals. The calculated hazard index (HI) indicated that each metal had low HI but, the cumulative impacts of all metals represented a real threat to fish consumers especially at site3. Metals elevation was highly correlated with Sabal discharges and regulations for water and fish consumption have to be applied.

“…Fish, in comparison to invertebrates, are more sensitive to many toxicants and are a convenient test subject for indication of ecosystem health [35]. Fish accumulate pollutants preferentially in their fatty tissues like liver and the effects become apparent when concentrations in such tissues attain a threshold level [20]. This paper was aimed at studying the histopathological alterations in kidney and liver of the catfish Clarias gariepinus exposed in River Galma polluted ecosystem in Zaria, Nigeria.…”

The river ecosystem serves as ultimate sink for myriads of xenobiotic all over the world with deleterious effects on the living biota within it. Histopathological alterations in kidney and liver of the catfish Clarias gariepinus (Burchell, 1822) were studied in River Galma, Zaria Nigeria. Twenty-five samples of Clarias gariepinus were exposed to the river ecosystem at the peak of rainfall in August, 2015 for 14 days at five stations along River Galma, using the cage system. Fish samples and controls from each station were subsequently harvested and transported to the laboratory for histopathological examination of liver and kidney. Results from photomicrographs of tissues from different stations revealed varying histopathological alterations which ranged from vacuolation, constrictions, necrosis and aggregations of cells to congestion of the blood vessels. These results indicated that River Galma is witnessing pollution. This calls for ameliorative measures by relevant authorities so as to protect aquatic life as well as the public from the toxic effects of aquatic environmental pollution.

“…The fish investigated for these elements in other works had similar levels of Zn compared to the higher values found in this study (Omar et al, 2014). Fish is an excellent source of zinc, a trace element in biological systems necessary to participate in the metabolism of carbohydrates, lipids, proteins and nucleic acids.…”

Concentrations of ten elements (Cd, Cr, Cu, Fe, Ni, Pb, Se, Sr, V and Zn) were determinate in muscle tissues of 13 fish species from Aratu Bay, Bahia, Brazil by inductively coupled plasma optical emission spectrometry. The accuracy and precision of our results were checked by using two certified reference materials: BCR-422 cod muscle and SRM 1566b oyster tissue. The average trace element concentrations in the fish species varied in the following ranges, in μg g0.03-0.8 for Cr; 2.0-33.7 for Cu, 2.4-135.1 for Fe, 1.6-25.6 for Se; 1.6-35.1 for Sr; and 2.8-40.5 for Zn. The Diaptereus rhombeus (carapeba) specie presented the highest concentrations of Se, Cu and Fe. Chromium and Se were present at levels above the limit of tolerance allowed by the National Agency of Sanitary Vigilance (ANVISA). The results were also evaluated using the multivariate analysis techniques: principal component analysis (PCA) and hierarchical cluster analysis (HCA).Keywords: seafood, chromium, selenium, composition, ICP OES. Avaliação de elementos químicos essenciais e contaminantes em treze espécies de peixes da Baía de Aratu, Bahia, Brasil ResumoForam determinadas as concentrações de dez elementos (Cd, Cr, Cu, Fe, Ni, Pb, Se, Sr, V and Zn) em tecidos de músculos de treze espécies de peixes da Baía de Aratu, Bahia, Brasil, utilizando a espectrometria de emissão ótica com plasma indutivamente acoplado. A precisão e exatidão dos resultados foram analisadas utilizando dois materiais de referência certificada: BCR-422 cod muscle e o SRM 1566b oyster tissue. A concentração média dos elementos traço nas espécies de peixes variaram nas seguintes faixas, em μg g −1 : Cr = 0, 8; Cu = 2,7, Fe = 2,1, Se = 1,[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]6; Sr = 1,1;. A espécie Diaptereus rhombeus (carapeba) apresentou as maiores concentrações de Se, Cu e Fe. Cromo e Se apresentaram níveis acima do limite de tolerância estabelecido pela Agência Nacional de Vigilância Sanitária (ANVISA). Os resultados ainda foram avaliados usando técnicas de análises multivariadas: análise de componente principal (PCA) e análise de agrupamento hierárquico (HCA).Palavras-chave: fruto do mar, cromo, selênio, composição, ICP OES.
