However, human-induced activities can potentially pollute Lake Malawi exposing <em>E. sardella</em> to heavy metals contamination. This could pose a food system health risk to the population of Malawians and neighboring countries, which heavily rely on fish as a source of animal protein. Therefore, this study investigated the concentration levels of Lead (Pb), Cadmium (Cd), Zinc (Zn), Copper (Cu), Manganese (Mn), and Iron (Fe) in sun-dried <em>E. sardella</em> and conducted a health risk assessment associated with its consumption. <em>E. sardella</em> samples were collected from Karonga, Nkhata Bay, Nkhotakota, Salima, and Mangochi districts in Malawi between December 2023 and February 2024. The results revealed significant variations in Cd, Zn, Cu, Mn, and Fe concentrations among the sampled sites while Pb contamination was not detected. The concentrations of Zn, Cu, Mn, and Fe in <em>E. sardella</em> were within acceptable consumption limits set by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) in 2012. However, the fish's average Cd levels (0.17 mg kg⁻¹ ww) were slightly above the recommended threshold of 0.1 mg kg⁻¹ ww by FAO/WHO (2012) but remained below the limit of 0.5 mg kg⁻¹ ww set by FAO in 1983. Furthermore, none of the analyzed heavy metals posed a health risk effect to people. Therefore, there is a need for regular monitoring of heavy metal concentrations in <em>E. sardella</em> and other mostly consumed fish species from Lake Malawi, both fresh and processed, for a sustained guarantee of the safety of the fish consumers.</p></div>","PeriodicalId":100480,"journal":{"name":"Environmental Chemistry and Ecotoxicology","volume":"6 ","pages":"Pages 354-362"},"PeriodicalIF":9.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590182624000328/pdfft?md5=33209dd290d21f22bd4727d59f72e450&pid=1-s2.0-S2590182624000328-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141963578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As human interactions with digital electronics such as computers and smartphones intensify, exposure to LCMs is a public health concern. Nevertheless, there is limited research on the occurrence of LCMs in biological and non-biological matrices. We developed a method to determine 60 LCMs in electronic-waste panels (i.e., computer monitors), indoor dust, feces, and urine using gas chromatography–mass spectrometry (GC–MS). Solid matrices (i.e., dust and feces) were extracted using a solid-liquid extraction (SLE) procedure whereas liquid matrices (i.e., urine) were extracted using solid phase extraction (SPE). Indoor dust and feces extracts were purified by passage through silica gel packed gravity columns. The method limits of detection (LODs) and quantification (LOQs) were in the ranges of 0.05–13.0 and 0.18–39.1 ng/mL, respectively. Recoveries of all target analytes fortified at concentrations of 10 and 100 ng/mL on LCD panels, dust, feces, and urine were in the range of 71–130%, with standard deviations of 0.01–33%. Repeated analyses of similarly fortified samples yielded intra-day and inter-day variations (CV) of 0.32–12.6% and 0.76–14.3%, respectively. Matrix effects, calculated from fortified matrices, ranged from −28.5% to 28.5%. The method was applied in the analysis of LCD panels, indoor dust, dog feces and urine, which were found to contain 22, 42, 46, and 18 of the 60 targeted LCMs, respectively. LCMs were found in LCD panels (∑LCM = 1780 ± 165 ng/cm² for desktop computer monitors; and 166,900 ± 80,100 ng/cm² for smartphone screens), indoor dust (∑LCM = 2030 ± 1260 ng/g), dog feces (∑LCM = 1990 ± 2000 ng/g dw), and urine (∑LCM = 24.0 ± 14.6 ng/mL).

The precarious results of it show a paramount imbalance in the natural ecosystem of many living beings. Such a devastating and toxic effect on our surroundings requires a long-lasting solution to safeguard its inhabitants. Additionally, studies have shown that MPs are consumed by a variety of organisms.

Traditional methods for the removal of HM-contaminated sites, such as physical and chemical treatments, often have limitations in terms of efficiency, cost, and potential negative impacts on the environment.

Bioremediation is a promising technology that utilizes the inherent abilities of microorganisms to degrade or transform pollutants into less harmful forms. Microbial exopolysaccharides have gained attention as potential tools in bioremediation strategies due to their unique physicochemical properties and their ability to interact with heavy metals. This work aims to provide an overview of the role of microbial extracellular polymeric substances (EPS) in the bioremediation of HM-contaminated sites. First, the mechanisms by which EPS facilitates heavy metal sequestration are discussed. EPS can form metal-complexing agents, such as chelators and ion-binding sites, which enhance the immobilization and precipitation of heavy metals, reducing their bioavailability and toxicity. EPS can act as a protective barrier, shielding microorganisms from heavy metal stress and facilitating their survival and growth. Additionally, EPS production can be induced or enhanced in response to heavy metal exposure, potentially increasing the efficiency of bioremediation processes.</p></div>","PeriodicalId":100480,"journal":{"name":"Environmental Chemistry and Ecotoxicology","volume":"6 ","pages":"Pages 408-421"},"PeriodicalIF":9.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590182624000109/pdfft?md5=9d5d88902dbb019e7b28df3b0368be7c&pid=1-s2.0-S2590182624000109-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141029152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
