Early Detection of Heavy Metal Pollution with Biological Markers in Freshwater Clam (Corbicula javanica) in Maros River, Indonesia
Scientists found that freshwater clams can serve as early warning systems for dangerous heavy metals like lead and cadmium in rivers by producing special proteins called metallothioneins when exposed to these pollutants. The clams showed signs of metal poisoning within just one to five weeks, making them useful "canaries in the coal mine" for detecting water contamination before it reaches dangerous levels. This matters because heavy metals in water sources can eventually make their way into drinking water and food, potentially harming human health.
Food-type may jeopardize biomarker interpretation in mussels used in aquatic toxicological experimentation
Researchers found that the type of microalgae diet fed to mussels (Mytilus galloprovincialis) under laboratory conditions significantly influenced biomarker responses, raising concerns about the reliability of biomarker interpretation in aquatic toxicology experiments when food type is not carefully controlled.
Pb Toxicity on Gut Physiology and Microbiota
This review summarizes the effects of lead toxicity on gut physiology and the intestinal microbiota across animal models and humans. Researchers found that lead exposure disrupts the gut barrier, alters microbial community composition, and can promote inflammation in the gastrointestinal tract. The study highlights the gut as an important but often overlooked target of lead toxicity, with implications for understanding how heavy metal exposure affects overall health.
Heavy metal accumulation in a bioindicator species, Limpet Patella caerulea, in Yalova (İzmit Bay): Risk assessment for human health
Researchers examined monthly heavy metal concentrations (cadmium, copper, lead, zinc, nickel, and iron) in the whole-body tissue of the limpet Patella caerulea as a bioindicator species in Izmit Bay, Marmara Sea, and conducted a human health risk assessment based on measured metal levels. The study found that cadmium levels exceeded safe limits in all sampled months and lead exceeded limits in autumn, indicating potential health risks for consumers of limpets from this heavily industrialized coastal area.

The Chemical and Microbiological Contaminants and Safety of Mussels
This review examines the range of chemical and microbiological contaminants found in mussels, which are widely consumed seafood and serve as indicators of water quality due to their filter-feeding behavior. Contaminants of concern include heavy metals, microplastics, persistent organic pollutants, PCBs, PFAS, and various pharmaceuticals detected in contaminated coastal waters.
Exposure to microplastics renders immunity of the thick-shell mussel more vulnerable to diarrhetic shellfish toxin-producing harmful algae
Researchers found that mussels previously exposed to microplastics became more vulnerable to toxic algae blooms, suffering greater immune system damage than mussels without prior microplastic exposure. The microplastics weakened the mussels' defenses by causing oxidative stress, cell death, and energy depletion, leaving them less able to fight off the algal toxins. Since mussels are widely consumed as seafood, this combined threat could affect both marine ecosystems and food safety for humans.
