Summary

This paper is not relevant to microplastics — it examines heavy metal (copper, chromium, manganese) accumulation and liver tissue damage in Indian oil sardines as an indicator of industrial pollution in a coastal ecosystem.

Body Systems

The discharge of heavy metals from industrial effluents into aquatic ecosystems is a major cause of serious aquatic pollution. The bioaccumulation of toxic heavy metals in aquatic species can lead to their transmission to the food chain, posing serious public health risks. Present study was done to assess heavy metal accumulation and histopathological analysis in the liver of Sardinella longiceps collected from Sassoon dock during the rainy season between 2019 to 2022. It was found that amongst studied heavy metals Cu, Cr, and Mn concentration was beyond the permissible limit of WHO and FAO guidelines. Histopathological analysis of liver tissues during the studied period showed various architectural alteration which could be due to the accumulation of heavy metals found in it.

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.

The accumulation of microplastics and their associated heavy metals on the surfaces of microplastics in various tissues of the pelagic fish Rastrelliger kanagurta, from the northern coast of Central Java, Indonesia

Researchers examined microplastic contamination in the tissues of pelagic mackerel from the northern coast of Central Java, Indonesia. The study found microplastics predominantly in fragment shapes smaller than 500 micrometers across gills, stomach, intestines, and liver, along with seven polymer types, multiple plastic additives, and heavy metals including manganese, chromium, and nickel adsorbed onto microplastic surfaces.

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.
