“…Changes in the physicochemical characteristics of water quality can have a detrimental influence on the physiological systems of aquatic creatures that are more susceptible to environmental changes (41)(42). Heavy metals have an effect on aquatic ecosystems either directly by producing toxicity in living organisms or indirectly by disrupting the stability of the food chain (43)(44)(45). A variety of other factors influence heavy metal bioavailability and uptake, including heavy metal quantity, exposure period, interactions with other metals, fish age and size, detoxification processes, fish metabolic procedures, feeding behavior, ecological physicochemical variables, and so on.…”

Introduction: Heavy metal pollution has become an important environmental issue today. This study was aimed to identify the heavy metals of the two fishing products namely demersal fish and cephalopods landed at Benoa Port, Bali Province and their health risk effects on consumers. Methods: Demersal fish and cephalopod products were obtained from local fishermen at Benoa port. Atomic Absorption Spectrophotometry (AAS) was used to specify the (Pb, Cd, and Hg) in 34 fish fillet products weighing an average of 500 grams each. Statistical software was used to conduct an analysis of the collected data, while THQ, TTHQ, and TCR were calculated and compared with USEPA regulations. Results and Discussion: The results of this research showed that the content of heavy metals in demersal fish and cephalopod products was lower than the levels suggested by official agencies in a number of countries. In populations of various ages, the target Hazard Quotient (THQ) for the heavy metal was less than 1. At this point, the Total THQ result did not imply any risk to human health from ingestion of these two fishery products. When these two products were ingested, the target cancer risk (TCR) did not represent a cancer risk. Conclusion: The outcomes of this study showed that the bioaccumulation levels of both fishery products with low levels of heavy metals are safe for human consumption.

“…Abundant research delineates that such exposures can catalyze a gamut of health complications, from cardiovascular ailments and cancers to diabetes and renal dysfunctions, etc (Yao et al, 2021). Two commonly encountered heavy metal contaminants, lead (Pb) and cadmium (Cd), amass in human systems owing to the biomagnification phenomenon in the food chain (Li et al, 2023). Pb exerts profound detrimental effects on the brain, injuring its vascular endothelium, leading to cerebral microvessel dysfunction.…”

Background: Selenium (Se) has been reported to have an antagonistic effect on heavy metals in animals. Nevertheless, there is a lack of epidemiological research examining whether Se can mitigate the adverse effects of cadmium (Cd) and lead (Pb) on hand grip strength (HGS) in middle-aged and elderly individuals.Methods: This study used data from the 2011–2014 National Health and Nutrition Examination Survey (NHANES). HGS measurements were conducted by trained examiners with a dynamometer. Concentrations of Se, Cd, and Pb in blood were determined via inductively coupled plasma mass spectrometry. We employed linear regression, restricted cubic splines, and quantile g-computation (qgcomp) to assess individual and combined associations between heavy metals and HGS. The study also explored the potential influence of Se on these associations.Results: In both individual metal and multi-metal models adjusted for confounders, general linear regression showed Se’s positive association with HGS, while Cd and Pb inversely related to it. At varying Se-Cd and Se-Pb concentrations, high Se relative to low Se can attenuate Cd and Pb’s HGS impact. An inverted U-shaped correlation exists between Se and both maximum and combined HGS, with Se’s benefit plateauing beyond approximately 200 μg/L. Stratified analysis by Se quartiles reveals Cd and Pb’s adverse HGS effects diminishing as Se levels increase. Qgcomp regression analysis detected Se alleviating HGS damage from combined Cd and Pb exposure. Subsequent subgroup analyses identified the sensitivity of women, the elderly, and those at risk of diabetes to HGS impairment caused by heavy metals, with moderate Se supplementation beneficial in mitigating this effect. In the population at risk for diabetes, the protective role of Se against heavy metal toxicity-induced HGS reduction is inhibited, suggesting that diabetic individuals should particularly avoid heavy metal-induced handgrip impairment.Conclusion: Blood Cd and Pb levels are negatively correlated with HGS. Se can mitigate this negative impact, but its effectiveness plateaus beyond 200 μg/L. Women, the elderly, and those at risk of diabetes are more vulnerable to HGS damage from heavy metals. While Se supplementation can help, its protective effect is limited in high diabetes risk groups.

“…Some key problems associated with heavy metal pollution include its toxicity to humans and wildlife, leading to acute and chronic health problems, including neurological disorders (Azar and Vajargar, 2023), kidney damage (Smereczański and Brzóska, 2023), cancer (Parida and Patel, 2023), and developmental issues in children (Zheng et al, 2023). Heavy metals can also negatively impact aquatic food chains, increasing the risk of toxicity for top predators (Li et al, 2023) and disrupting ecosystems by harming key species, reducing biodiversity, and altering nutrient cycling (Li et al, 2023). This can lead to the exposure of sensitive species, resulting in imbalances within ecosystems (Angon et al, 2023).…”

In this study, we investigated the heavy metal absorption of Alcaligenes faecalis strain U.B.I., a bacteria isolated from a mining site, under different environmental conditions. We utilized both conventional and molecular techniques to identify the bacteria and employed response surface methodology (R.S.M.) to determine optimal environmental conditions for heavy metal absorption. Our analysis revealed that the heavy metal-tolerant bacteria belong to the Proteobacteria, specifically the Betaproteobacteria order in the Burkholderiales family. Additionally, the bacteria’s phylogenetic characteristics indicated a close relationship between the Aeromonas sp. cluster and members of the Aeromonadaceae family. Our results showed that the biomass A. faecalis strain U.B.I. had an optimal potential for chromium (Cr+) absorption at 93.0%. We also conducted tests on the biomass under optimized conditions for lead (Pb2+) absorption using R.S.M., resulting in a mean heavy metal uptake of 89.99%. Furthermore, we analyzed the surface functional groups after interaction with heavy metals and observed a significant shift in position of the functional groups. The O-H stretch and H-bonded at the 3268 cm1 position, while C=C stretch and N-O asymmetrical stretch/C-O stretch occurred at positions 2195 cm-1 and 1629 cm-1 of the spectra, respectively. Our findings suggest that the biomass of A. faecalis strain U.B.I. has potential for heavy metal bioremediation and can be used for heavy metal biosorption under various environmental conditions.
