Heavy metal contamination in marine ecosystems poses a critical environmental challenge, with significant implications for biodiversity, trophic dynamics, and human health. Marine fish are key bioindicators of heavy pollution because their role food webs capacity bioaccumulation transfer. This review synthesizes current knowledge on the pathways mechanisms accumulation fish, focusing factors that influence uptake, retention, tissue distribution. We explore processes governing transfer biomagnification, highlighting species-specific patterns risks posed to apex predators, including humans. Additionally, we assess ecological consequences at population, community, ecosystem levels, emphasizing its effects reproduction, community structure, interactions. By integrating recent findings, this highlights gaps suggests future research directions improve monitoring risk assessment. Given persistence bioavailability metals environments, effective control strategies sustainable fisheries management imperative mitigate long-term public health risks.

Abstract Studies on virus inactivation by metal nanoparticles indicate that antiviral activity is influenced the stabilizer particle surface. Additionally, cerium oxide stabilized with boric acid (BA-CeO 2 ) exhibit potent activity. However, previous studies utilized BA-CeO dispersed in liquid form and did not fully account for practical application of materials real-world environments. We investigated nonwoven fabric coated (NC-NWF). When a medium containing viruses was placed NC-NWF, titers mouse hepatitis (MHV), influenza A virus, feline calicivirus were reduced > 99% within h. Furthermore, transmission MHV assessed cages lined NC-NWF. The divided into two compartments using mesh housing infected uninfected mice either side. results indicated significantly lower antibody titer against naïve NC-NWF partition than control partition. placing h, followed 24 resulted those fabric. These findings suggest exhibits retains efficacy living environments, such as rearing cages.
