“…They [40] reported that arsenic in periwinkle was above the FAO/WHO acceptable limit with a value of 2.31±0.24 mg/kg. More so, the results seen in our study is in line with the findings of Kuplulu et al [41]. They [41] also reported that As levels in seafoods in turkey were below FAO/WHO acceptable limits but the highest concentrations were seen in Shrimps.…”

To assess and compare the levels of arsenic, cadmium, mercury and lead, in common seafoods (mudskippers, periwinkle and Shrimp) consumed in Rivers state obtained from different creeks of Rivers State Nigeria. Study Design: Commonly consumed seafoods in Rivers State: Periopthalmus barbarous (mudskipper), Pandalus borealis (shrimp) and Tympanotonus fucatus (periwinkle) were collected at 5 different occasions from each of the study location (creek): Eagle Island, Iwofe, Bodo and Borokiri creeks in Rivers State. Eagle Island and Iwofe creeks are in Obio/Apkor and Degema LGA respectively, Borokiri Creek is in Port Harcourt LGA while Bodo creek is located in Gokana LGA. Study Area: The study was carried out in the Department of Medical Laboratory Science, Rivers State University between the periods of June, 2018 – March, 2019. Samples of seafoods were collected from Bodo, Eagle Island, Borokiri and Iwofe creeks of Rivers State for 5 times at interval of 30 days between the periods of June, 2018 – October, 2018 during the wet season. Methodology: Periopthalmus barbarous, Pandalus borealis, and Tympanotonus fucatus were collected from Eagle Island, Iwofe, Bodo and Borokiri creeks. The samples were correctly labeled, dried in an oven at 80°C, ground to powdered form then sieved to attain homogenous particles. Each sample was weighed, recorded and the concentrations of metals in the samples were determined. Two (2) grams each of the ground samples were weighed and put into a beaker with 6mls of nitric acid (HNO3) which was added as oxidizing acid to break the sample matrix and 2ml of perchloric acid as a reagent with 2 mls of de-ionized water was added to blend it. The sample was place on a heating mantle at 105°C until the sample volume reduced to two third of its original volume, the sample color clear and turns yellowish and its entire component was digested. The concentration of HMs: lead, arsenic, cadmium and mercury in the digested seafood samples were analysed using Atomic absorption spectrophotometer (AAS). The concentration of HMs from the sample were determined from the absorbance calibration in parts per million (ppm) or mg/kg dw. Results: The bio-concentration mercury and arsenic in the selected seafoods from the creeks were below the World Health Organization permissible limits while levels of cadmium and lead in the seafoods in the order of periwinkle>mudskipper>shrimp collected from these creeks were above the FAO/WHO permissible limits of 0.5 1.0 mg/kg dw and 2.0 mg/kg dw respectively. Conclusion: Mudskipper, periwinkle and shrimp were observed to bio-accumulate HMs beyond FAO/WHO permissible limits. Toxicities of these HMs in humans could induce several clinical derangements and eventually death if drastic measures are not put in place to stop or limit these anthropogenic activities.

“…Therefore, the dataset that was used for elaborating the models presented in current research did contain some values of Cd [ 72 , 73 ] and Pb [ 74 , 75 , 76 ] over the maximum levels that were regulated by European Law (Directive 2006/1881/EC).…”

“…Additionally, FishBase ( ) considers Scophthalmus maeoticus (Pallas, 1814) as a synonym of Scophthalmus maximus (Linnaeus, 1758). Therefore, all three names that appear in the scientific literature used in present study, Scophthalmus maeoticus [ 106 ], Psetta maxima maeotica [ 72 , 75 , 76 , 100 , 101 , 102 , 107 , 109 ], and Scophthalmus maximus [ 73 , 74 , 99 , 103 , 108 ].…”

Metals are considered to be one of the most hazardous substances due to their potential for accumulation, magnification, persistence, and wide distribution in water, sediments, and aquatic organisms. Demersal fish species, such as turbot (Psetta maxima maeotica), are accepted by the scientific communities as suitable bioindicators of heavy metal pollution in the aquatic environment. The present study uses a machine learning approach, which is based on multiple linear and non-linear models, in order to effectively estimate the concentrations of heavy metals in both turbot muscle and liver tissues. For multiple linear regression (MLR) models, the stepwise method was used, while non-linear models were developed by applying random forest (RF) algorithm. The models were based on data that were provided from scientific literature, attributed to 11 heavy metals (As, Ca, Cd, Cu, Fe, K, Mg, Mn, Na, Ni, Zn) from both muscle and liver tissues of turbot exemplars. Significant MLR models were recorded for Ca, Fe, Mg, and Na in muscle tissue and K, Cu, Zn, and Na in turbot liver tissue. The non-linear tree-based RF prediction models (over 70% prediction accuracy) were identified for As, Cd, Cu, K, Mg, and Zn in muscle tissue and As, Ca, Cd, Mg, and Fe in turbot liver tissue. Both machine learning MLR and non-linear tree-based RF prediction models were identified to be suitable for predicting the heavy metal concentration from both turbot muscle and liver tissues. The models can be used for improving the knowledge and economic efficiency of linked heavy metals food safety and environment pollution studies.

The fish's inner ear consists of three interconnected semicircular canals and otolith organs located in these canals, which are responsible for balance and hearing. Abnormalities in these organs can affect the vital activities of the fish. The main purpose of this study was to determine the morphological and morphometric characteristics of abnormal and normal sagittal otoliths in the four flatfish species (Lepidorhombus boscii, Platichthys flesus, Solea solea, and Pegusa lascaris) sampled from three seas (Aegean Sea, Mediterranean Sea, and Black Sea). Abnormalities in otoliths are investigated using light microscopy, scanning electron microscopy, and Raman spectroscopy. The otolith morphometric measurements and morphology are recorded for abnormal and normal otoliths for each species. It was determined that the four flatfish species examined in the present study showed differences in the morphological features of normal and abnormal otoliths in the blind and eyed sides. In addition, statistical differences were observed when the weight, length, width, perimeter, and area values of normal and abnormal otoliths of all species were compared (p < .05). The four types of saccular otoliths were defined, one normal (type 0) and three abnormal (type 1, type 2, and type 4) for four flatfish species. The current study presents for the first-time abnormal otolith morphology information on blind and eyed side sagittal otoliths in these flatfish species. Abnormalities in the anatomical structures of bony parts such as otoliths in fish may be caused by pollution, nutritional problems, stress, and environmental factors as well as a combination of these.
