“…In Italy, crustacea and mollusks had a higher mean Ni concentration of 0.626 mg/kg than fish (0.046 mg/kg) [ 28 ]. Processed shellfish are more likely to be exposed to Ni and be contaminated because of benthic and filter feeding [ 63 ]. Biological dilution was observed in the transfer of Ni among aquatic foods, which could mean higher Ni concentrations in low-trophic-level aquatic foods than in high-trophic-level aquatic foods [ 17 ].…”

Nickel (Ni) is a silver-white metal with high antioxidative properties, often existing in a bivalent form in the environment. Despite being the fifth most abundant metal on Earth, anthropogenic activities, including industrial processes, have elevated Ni levels in environmental media. This study investigated Ni contamination in various food groups in Zhejiang Province, China, mainly focusing on Ni levels in beans, vegetables, aquatic foods, meat products, cereal products, and fruits. A total of 2628 samples were collected and analyzed. Beans exhibited the highest Ni content in all samples. The overall detection rate of Ni was 86.5%, with variation among food categories. For plant-origin foods, legumes had the highest Ni concentration while for animal-origin foods, shellfish showed the highest median Ni concentration. The results indicate generally acceptable Ni exposure levels among Zhejiang residents, except for children aged 0–6. Beans were identified as the primary contributor to high Ni exposure risk. The paper suggests monitoring Ni contamination in food, especially for vulnerable populations, and provides insights into exposure risks in different age groups.

For the humankind, water quality of natural resources is the most important and freshwater molluscs are used as bioindicators for the evaluation of water quality in biomonitoring studies. Viviparus contectus (Viviparidae: Gastropoda) is a species freshwater snail and consumed by people. Herein, the concentrations of heavy metals heavy metal (Cd, Cr, Pb, As, Zn and Cu) were measured in water and Viviparus contectus samples. The water quality (temperature, pH, and dissolved oxygen) were seasonally determined in water samples. The present study showed that the metal accumulation in the water and soft tissues of freshwater snail were in the order of Pb > Cr = Zn = Cu = Cd = As and Zn > Cu > Pb > Cd > As = Cr, respectively. The elevated levels of heavy metals (As, Cr, Cu, Zn and Hg) were recorded in autumn. Seasonal variations affected signi cantly Pb concentration in the freshwater snail samples (P < 0.05). EDI (estimated daily intake) values were lower than the recommended tolerable daily intake (TDI) values for adults and the values of HI (hazard index) were lower than 1 for adults. Zn and Pb values in freshwater snail samples were above the limits according to the Turkish Food Codex, FAO/WHO, JECFA and EC limit values. The water analysis indicates mean concentrations of metals below the maximum permissible limits established by the World Health Organization, Turkish Pollution Control Regulation and USEPA, except Pb.Overall, anthropogenic activities adversely affected aquatic ecosystems and this study can be provided a useful data set for metallic contamination in aquatic bodies and biomonitoring studies in freshwater ecosystems.

ARTICLE HIGLIGHTS- Nickel mining activities significantly impacted the ecological integrity of the Pomalaa coastal area in Southeast Sulawesi, particularly in the mangrove ecosystem.- The exposure of overburden waste in the mangrove ecosystem has led to the loss of important gastropod species and a decline in population of surviving species- The low population of gastropod species in nickel mining impact areas indicates extensive environmental damage caused by these activities.ABSTRACTGastropod resources in the Dawi-Dawi mangrove ecosystem, Southeast Sulawesi are greatly influenced by the input of overburden waste (sediment) from nickel mining activities. This condition has been going on for the last 2 decades and has degraded the habitat and structure of the gastropod community. The upstream connectivity (the existing nickel mining area) and the Dawi-Dawi River estuary mean that the mangrove forest (estuary) in this area is continuously affected by (massive) overburden runoff. This research was carried out in June-August in the mangrove ecosystem of Dawi-Dawi Village, Southeast Sulawesi Province. This research aims to determine the existing condition of mangrove gastropods affected by overburden. This research began by conducting initial observations in the field, to identify mangrove ecosystems affected by overburden. research stations were determined using a purposive sampling technique (targeted) and sampling gastropods using a simple random sampling method. The ecological index of the mangrove gastropod community affected by overburden shows a tendency for a medium diversity index (H'=1.81), low species richness (R=1.42), high evenness (E=1.12), and no dominance of certain species (C=0.19). The gastropod species found are typical types that make up the mangrove fauna, namely Terebralia sulcata, Terebralia palustris, Faunus ater, Telescopium telescopium, Hebra nigra, and several taxa (genus) of climbing Littoraria snails (periwinkle) which are found in the roots, stems and leaves of mangroves. The abundance of gastropods obtained was also very low, namely around 0-12 Ind./m2. At some points (rarely) schools of small snails of the type T. sulcata (5-21 Ind./m2) are sometimes found. This research shows de facto that overburden waste eliminates (survival) or reduces the diversity and richness of gastropod species (ecological index) in the mangrove ecosystem of Dawi-Dawi.
