“…Recently, Bat [22] reviewed the results of the selected heavy metals (Fe, Zn, Ni, Cu, Mn, Pb, Cd and Co) in fish captured from the Black Sea coasts of Turkey and the metal concentrations decrease in the order Zn>Fe>Cu> Mn>Pb>Ni>Co>Cd. Below is a summary of the general distribution of the eight heavy metals in the tissues and organs: In general, results of the present study show a trend similar to what many authors have pointed out before around the world, about the accumulation of these metals in fish tissues [7,10,[23][24][25][26][27][28][29]. Also, authors agree that liver is the highest concentrations of heavy metals analysed are shown.…”

In the present study, Scomberomorus commerson was collected during the period 2006-2011 in order to provide information on the concentrations of eight heavy metals present in this marine species commonly consumed by the population and to have knowledge whether these levels may constitute a hazard to consumers. Liver showed high concentrations of metals in the tissues and organs. Fe is the most accumulated in all tissues and organs. The highest mean concentration of Fe (608.93+113.22 µg/g), Mn (9.79+4.22 µg/g), Cu (38.57+16.62 µg/g), Zn (53.25+26.50 µg/g), Ni (3.22+1.13 µg/g), Pb (1.20+0.64 µg/g), Cd (2.03+0.91 µg/g) and Cr (1.93 + 0.87 µg/g) was determined in liver of fish. The order of abundance of the metals in the fish samples based on concentrations in the muscle tissues analysed were as follows: Fe>Zn>Cu>Mn>Ni>Cd>Pb≥Cr. For the toxic metal, Pb was found to have lower concentration of the mean values than the permissible limits set by FAO/WHO. However, Cd level was higher than the permissible limit and it can be concluded that the contamination of Cd in S. commerson may pose threat for the importers due to high per capita consumption of the fish.

“…Data that were related to heavy metal concentration in turbot muscle and liver tissues, as reported in Europe (including Turkish Black Sea coast), were collected from the scientific literature [ 72 , 73 , 74 , 75 , 76 , 99 , 100 , 101 , 102 , 103 , 104 , 105 , 106 , 107 , 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.

“…Heavy metal levels in liver and in digestive system tract tissues or organs offish are also higher than those in edible muscles at significant levels. Many studies argued that liver is the main detoxification destiny and one of the most important metal storage organs by the digestive tract (Agusa et al, 2007;Farkas et al, 2002;Jaffar et al, 1988;Khaled, 2004;Krishna Kumar et al, 1990;Sobhanardakani et al, 2011;Sofia, 2005;Turkmen et al, 2009;Yousuf & Ahmed, 2010;Bat et al, 2012). It should be kept in mind that the most metals especially non-essentials stored in the liver and kidney depends on the intensity of exposure time and state of renal excretory function.…”

Many chemicals especially heavy metals that are exist in fish are essential for human life at low amounts, but can be toxic at high amounts. Other chemicals such as Hg, As, Cd and Pb have not any essential function in biota and are toxic even at very low amounts when ingested for a long period. The aim of this review is to compare and evaluate heavy metal levels in commercial fish species from the Arabian Sea and coastline in other seas. In this review, Mackerels, Tunas and Bonitos species, the most commercial of Scombridae family, were chosen. The state of the metal pollution levels of these fishes is revealed under the light of the literature. The chemicals, some of which are the most important heavy metals such as Zn, Fe, Cu, Pb, Cd, Hg, As, Cr and Mn were chosen and their amounts in commercial fish were evaluated.Most of studies showed that essential metals in fish species are much high, but the quantities of non-essential metals in edible tissues of fish are found to be less. This review has shown that fish are used as bio-monitoring in heavy metal pollution. It is suggested that such investigations should be continuous in terms of both human health and determination of metal pollution of our coasts.Öz: Özellikle balıklarda bulunan birçok kimyasal madde, düşük miktarlarda insan yaşamı için çok önemlidir, ancak yüksek miktarlarda zehirli olabilir. Hg, As, Cd ve Pb gibi diğer kimyasalların canlıda önemli bir işlevi yoktur ve uzun bir süre çok düşük miktarlarda bile gıda yoluyla alınırsa zehirlidir. Bu derlemenin amacı özellikle Arap Denizi ve diğer denizlerdeki kıyı şeridinden yakalanan ticari balık türlerindeki ağır metal seviyelerini karşılaştırmak ve değerlendirmektir. Bu derlemede, Scombridae ailesinin en ticari balıkları olan uskumru, tonbalığı ve palamut türleri seçilmiştir. Bu balıkların metal kirlilik düzeylerinin durumu, literatür ışığında ortaya konulmuştur. Zn, Fe, Cu, Pb, Cd, Hg, As, Cr ve Mn gibi en önemli ağır metaller olan kimyasallar seçilmiş ve ticari balıklardaki miktarları değerlendirilmiştir.Çalışmaların çoğu, balık türlerindeki gerekli metallerin çok yüksek, ancak balıkların yenilebilir dokularındaki gerekli olmayan metallerin miktarlarının daha az olduğu bulunmuştur. Bu derleme balıkların ağır metal kirliliğinde biyo-izleme olarak kullanıldığını göstermiştir. Bu tür araştırmaların hem insan sağlığı hem de kıyılarımızdaki metal kirliliğinin belirlenmesi açısından sürekli olması önerilmektedir.Anahtar sözcükler: Ağır metal, ton ve uskumru balıkları
