“…Similar results were reported by several studies showing that muscle is not an active tissue in accumulating heavy metals. Tapia et al [8] determined that the concentrations of the metals are higher in the samples of liver than in the muscle tissue samples, in both male and female marine organisms. In a study, Hoseini and Tahami [22] reported that the bioaccumulation of heavy metals in liver tissue is higher than muscle tissue in aquatic organisms.…”

“…invertebrates such as mussels, oysters, or lobster, are used to observe sea pollution [7] and their livers are also a good indicator of the presence of contaminants in the medium. Liver plays an important role in the storage, redistribution, detoxification, and transformation of contaminants [8].…”

Five fish species and one shrimp species from the Subarnarekha river were analyzed for heavy metals using inductively coupled plasma-mass spectrometry. The geometric mean concentration of As, Cd, Cu, Fe, Pb, Ni, Zn, Cr, Co, and Sr for all the samples was found to be 0.248, 0.031, 5.16, 104.9, 0.121, 4.68, 52.2, 0.784, 0.207, and 42.86 mg kg(-1)fresh, respectively. The concentrations of metals in the fish and shrimp exceed the limits of Indian and FAO standards for food for As, Cu, Ni, Cd, and Zn in many samples. The mean target hazard quotient (THQ) values for the 10 metals were below one for all the samples; however, the maximum THQ was more than one for shrimp in case of As, Cu, and Cr. The results indicate that the concentration of metals in some species, especially shrimp, at some locations is alarming and do present an appreciable hazard risk on human health.

“…The vials were left to cool at room temperature and volumetrically transferred to 25 mL volumetric flasks and topped up with ultra-purified water. The heavy metal (Pb, Cd, Cr, Cu, Co, Zn, Ni, and Fe) concentrations in all samples were determined by atomic absorption spectrophotometer (AAS) (Model AA-7000, Shimadzu Corporation, Japan) using an air-acetylene flame with digital read-out system [30][31][32]. Samples were aspirated through the nebulizer, and the absorbance was measured against a method blank as a reference.…”

Turning Waste into A Resource: Isolation and Characterization of High-Quality Collagen and Oils from Atlantic Bluefin Tuna Discards

et al. 2022

At the behest of the Green Deal, circular economy concepts are currently being widely promoted, not least within the aquaculture sector. The current study aims to demonstrate the technical feasibility of extracting collagen and fish oils from waste Atlantic bluefin tuna biomass originating from the Maltese aquaculture industry. For collagen, a three-stage methodology, consisting of pre-treatment, extraction, and retrieval, was applied to biomass originating from bone, skin, muscle, and internal organs (offal) in order to extract both acid-soluble collagen (ASC) and pepsin-soluble collagen (PSC). The chemical identity of the extracted collagen was confirmed through the conduction of hydroxyproline and SDS-PAGE tests as well as through FTIR, whilst the extracted collagen was also tested for its microbiological and heavy metal profiles. The collagen yield was found to be highest for skin tissue and for PSC-based protocols and is comparable to the yield cited in the literature for other tuna species. Oils were extracted through low temperature, high temperature, and enzymatic means. The fatty acid profile of the extracted oils was assessed using GC-FID; this indicated high proportions of EPA and DHA. Yield indicated that the enzymatic extraction of oil is most effective. High heat and the presence of iron-containing muscle starting material promote oxidation and rancidity. Further effort into the optimization of both collagen and lipid extraction protocols must be invested, with a special focus on the production of high-value fractions that are much closer to the quality required for human use/consumption.
