“…Lead and cadmium have the highest biomagnification levels from prey to predator. In contrast, copper has the least sign of biomagnification in the food chain [ 20 , 23 ]. It has been also reported that demersal fish and benthic communities generally have higher concentrations of arsenic, cadmium, chromium, copper, and zinc [ 90 ], which is consistent with the results of this study.…”

“…Cu may result from traffic emissions (diesel oil), marine engineering, and industrial/domestic wastewater. Phosphate fertilisers may contribute to high Cd and Cu levels [ 22 , 23 ]. Pb and Cd, non-essential metals, are EU-WFD priority hazardous substances; Zn and Cu are essential and act as important co-factors in many biochemical processes but become toxic above a threshold concentration [ 24 , 25 ].…”

Biotic samples from Algeciras Bay (South-west Europe) were studied to assess its ecological status, complementing the previous abiotic monitoring of trace metals in water and sediments. This bay is a densely populated area with intense port traffic and is highly industrialised with metal inputs. To study the impact of this, Zn, Cd, Pb, and Cu contents were determined in tissues of benthic (Solea senegalensis) and benthopelagic species (Scorpaena porcus, Trigloporus lastoviza, and Diplodus sargus sargus). Notable levels of Zn and Cu were found in the liver and gills of all fish species. Compared to international muscle guidelines, Pb sometimes exceeded the most restrictive values, outstanding S. porcus with 27% of samples above the permissible value. Metal pollution indexes revealed that the liver and gills of benthic species were more affected by metal pollution than benthopelagic species, especially in most industrialised sites. Particularly, S. senegalensis presented a higher accumulation factor from sediment of Cd and Cu in the liver (30.1 and 345.1), probably due to the close interaction as benthic species. Among the species studied, S. senegalensis and D. sargus sargus proved to be the best representative and useful bioindicators of metal-polluted environments as this bay. The results were consistent with the findings from the abiotic samples.

“…In this area, the main sources of Zn include fossil fuel burning, traffic emissions (gasoline), or industrial/domestic wastewater; Cd sources include metal smelting and refining, fuel burning, metal processing, and wastewater treatment facilities; Pb sources are petrochemical industries processes, coal combustion, traffic emissions (maritime transport), and ocean engineering; and Cu sources include traffic emissions (diesel oil), ocean engineering, and industrial/domestic wastewater. Phosphate fertilizers may contribute to high levels of Cd and Cu [ 21 , 22 ]. All these anthropogenic influences are also causing great social concern.…”

The ecological status of Algeciras Bay (South-west Europe), highly influenced by anthropogenic activities, was assessed by monitoring Zn, Cd, Pb, and Cu in water and sediment samples. Total contents and metal fractions with different availabilities and their spatial-seasonal distribution were determined. The trend in water and sediment contents were Zn > Pb ≈ Cu > Cd, without significant seasonal variations. Sites 3 and 4, closest to industrial activities, had the highest metal concentrations, mainly in sediments. Cd showed low partition coefficient in water, indicating higher bioavailability. Total metal content in sediments exceeded the threshold effect level for Cu and were close to Pb. The BCR procedure revealed the highest availabilities for Cd and Pb, due to its higher content in exchangeable and reducible fractions. Higher Pb levels (21.4 ± 5.1 mg/kg) were found in sediments of this bay compared with other ecosystems. Pollution indexes for sediment quality revealed that site 3 was the most polluted (CF = 7.12 and Igeo = 2.25). For an integrative study of the ecological status of this significant bay, these results have been complemented with the metal evaluation in benthic and benthopelagic fish tissues in Ecological status of Algeciras Bay, in a highly anthropised area in south-west Europe, through metal assessment—Part II: Biotic samples.

“…If HMs contaminate benthic fauna, it negatively impacts the survival and repopulation of its consumers in the trophic chain, which is significant. In addition, the supply of micronutrients and macronutrients from marine resources, such as mollusks and fish, is essential for human health; therefore, their entry will be linked to biomagnification of HMs [7]. As top predators, humans can come into contact with HMs by consuming species that live in contaminated sediments, such as bivalve mollusks, which are potentially bioaccumulating species of these elements in high concentrations [8].…”

The present study was conducted to quantify the heavy metals cadmium, lead, copper, chromium, nickel, and zinc in the bivalve mollusk concha prieta (Anadara tuberculosa) using inductively coupled plasma optical emission spectroscopy (ICP-OES). This research aims to identify whether the bioaccumulated content of heavy metals exceeds the maximum limits established by various public health bodies such as the ONU, FAO, Codex Alimentarius, EEC, and NHI. Samples of the species were collected randomly from three locations in Puerto El Morro, Playas Municipal Market, and La Libertad Seafood Market in the Gulf of Guayaquil. Thirty-three soft tissue samples of Anadara tuberculosa were evaluated, and the values quantified in mg/kg were in the following order: Zn > Cu > Cd > Ni > Cr > Pb.
