Researchers examined chemical element accumulation and microplastic occurrence in small pelagic fish from coastal waters, contributing baseline data on contaminant exposure in mid-trophic level species that are often overlooked in pollution assessments.
Exploring synergistic contamination of heavy metals and microplastics in marine edible fishes and associated risk status in humans
Researchers assessed heavy metal and microplastic contamination in multiple marine fish species along the Gujarat coastline and found substantial spatial and interspecies variation. Some species exceeded safe metal thresholds, and MP contamination was prevalent, with combined exposure posing amplified health risks for local consumers.
Microplastics and heavy metals in the sediment of Songkhla Lagoon: distribution and risk assessment
Researchers surveyed microplastic and heavy metal contamination in the sediments of Songkhla Lagoon, the largest lagoon in Thailand. They found microplastic fibers and fragments at every sampling site, with concentrations highest near the lagoon mouth, alongside elevated levels of metals like zinc, copper, and lead. Since local communities rely on the lagoon for fishing and food, the combined presence of microplastics and heavy metals in sediments raises direct concerns about contamination entering the human food chain.
Investigating a probable relationship between microplastics and potentially toxic elements in fish muscles from northeast of Persian Gulf
Researchers measured microplastic and metal concentrations in the muscles of benthic and pelagic fish species from the northeastern Persian Gulf. They found that microplastic and mercury levels increased with fish size, and estimated that consuming moderate portions of fish weekly provides essential nutrients without significant health risk. The study suggests that while fish remain a beneficial food source, monitoring microplastic and metal co-contamination in seafood is important for consumer safety.
Microplastic pollution and heavy metal risk assessment in Perca fluviatilis from Anzali wetland: Implications for environmental health and human consumption
Researchers analyzed heavy metals and microplastics in the tissues of European perch from Anzali Wetland in Iran and found contamination in muscle, liver, and gill samples. Microplastics were present in all fish examined, with fibers being the most common type. The study raises concerns about potential health risks for people who regularly consume fish from this polluted wetland.
Bioaccumulation and Bioremediation of Heavy Metals in Fishes—A Review
This review summarizes how heavy metals accumulate in fish tissues through contaminated water and enter the human food chain, posing serious public health concerns. The paper discusses bioremediation techniques using microorganisms and other methods to remove heavy metals from aquatic environments, which is relevant because microplastics can carry and concentrate these same toxic metals.
Microplastics and heavy metals in freshwater fish species in the southwestern region of Bangladesh: An emerging concern for public health
Researchers examined seventeen freshwater fish species from Bangladesh and found microplastics in all of them — mostly tiny fibers under 1mm made of polyethylene — alongside concerning levels of heavy metals including chromium and lead. While microplastic-linked health risks were low to moderate, the heavy metal contamination posed elevated cancer risks for people who regularly eat these fish.
Konsentrasi Logam Berat Timbal (Pb) dan Tembaga (Cu) pada Hasil Tangkapan Nelayan Pesisir Semarang dan Tegal Jawa Tengah
This study measured lead (Pb) and copper (Cu) concentrations in fish caught by coastal fishermen in Semarang and Tegal, Central Java, Indonesia. Heavy metals were detected in fish tissues, reflecting contamination in the coastal waters. Since microplastics can adsorb and concentrate heavy metals before being ingested by fish, they may amplify the metal burden in seafood consumed by local communities.
Accumulation of cadmium and lead in macroinvertebrates in relation to sediment concentration and the dynamics of environmental parameters in a tropical estuary of the Colombian Pacific
This paper is not relevant to microplastics research — it investigates the accumulation of cadmium and lead heavy metals in macroinvertebrates from a tropical Colombian estuary, focusing on metal pollution rather than microplastic contamination.
