“…Higher copper contamination in liver tissue dealt with by Kim and Kang (2004), this study strongly justifies the situation of this research. In this experiment, the pangas muscle contained a significant amount of Ni rather than other fish tissue; this statement partially supported by Mwakalapa et al (2019). Ali and Khan (2018) Zabir et al, 2016, Rajeshkumar and Li, 2018.…”

In this study, pangas and feed samples were analyzed to estimate the levels of metallic elements and to profile the human health risks due to consumption of contaminated fish. This investigation confirmed significant variations in heavy metal concentrations among different tissues of pangas in the order of Ni> Cu> Pb> Cd> Cr in pre-monsoon; and Ni> Cd= Cu> Pb= Cr in post-monsoon. Considerably higher concentrations of Pb, Cu and Cr were estimated in liver; and Cd and Ni were detected in muscle than other organs (p>0.05). Statistically significant higher amount of Cd, Ni, and Cu were observed in pre-monsoon than post-monsoon. Furthermore, three metal pairs showed significant association (Pb-Ni and Pb-Cu involved positively; Cd-Ni acted negatively). In pre-monsoon, Cd, Pb, Ni, Cu concentrations of feed significantly differed than pangas contents; whereas only Cu varied during the post-monsoon. Regression analysis revealed the significant effect of Ni content in feed on the Cu deposition of pangas (p-value 0.027, that was <0.05). For the assessment of potential human health risk of the studied metals, estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI) and carcinogenic risk (CR) indices were calculated. Studied EDI indicated that an average adult ingested a higher amount of Ni and Cu than the recommended intake limit. Nevertheless, only the higher EDI of Ni increases the value of THQ and HI than standard limit indicates adverse non-carcinogenic risk. However, lower CR of Pb confirmed no serious health hazard due to the ingestion of pangas. Factor analysis through principal component and cluster analysis suggested that higher concentrations of Pb and Ni may regulate by the feed used, geochemical properties or rapid industrialization in the study area. A proper monitoring for controlling the quality of fish feed with sustainable planning for industrialization could secure the booming of pangasius aquaculture in Bangladesh.

“…Therefore, in recent years, numerous studies have focused on potential risks of heavy metals to human health through fish consumption [ 1 , 4 , 47 , 48 , 53 ]. The majority of studies published to date predominantly focus on toxic metals in fish meat [ 30 , 33 , 58 ], vegetables, fruits [ 3 , 20 , 34 ], and cereal crops [ 37 , 38 , 43 , 44 ] as well as their levels and comparisons to various allowable limits.…”

Common carp (Cyprinus carpio) is one of the most important cultured fish species in Poland. The aims of our study were to determine the concentration of essential minerals in the muscle tissue of carp obtained from a pond culture and to compare the content of these minerals with the physiological norms of nutrition for the Polish population, Recommended Dietary Allowances (RDA), and Estimated Average Requirements (EAR). The non-carcinogenic and carcinogenic risk by assessment of the Estimated target hazard quotients (THQ), total target hazard quotients (ΣTHQ), and carcinogenic risk were also studied. The muscle tissue of the carp was rich in macroelements. The pattern significance gradation of element concentrations was as follows: Na > K > Ca > P > Mg > Al > Zn > Fe > Cu > Mn > Cr > Se > Co. The concentration of toxic heavy metals in the samples was lower than the maximum allowable level of metals in food products. The risk of consumption of toxicants by an adult at a daily intake of 100 g of fish was 1.45% for Pb, 0.1% for Hg, 0.02% for Cd, and 0.02% for As, compared to the allowable daily intake for each toxicant. The value of the target hazard quotients of each metal was less than 1, indicating that the intake of a single metal through the consumption of carp meat does not pose a considerable health hazard. The total value of the target hazard quotients was also less than 1, indicating the safety of the combined effects of the chemicals. The major risk contributor was Pb with 82.9%, followed by Hg (9.38%), As (6.43%), and Cd (1.29%).
