Toxicological assessments of basic blue 3 dye in fresh water bivalve Lamellidens marginalis
The freshwater bivalve Lamellidens marginalis was exposed to Basic Blue 3 dye at 40 and 70 ppm for 96 hours to assess acute physiological and histological effects. Elevated antioxidant enzyme activities were recorded in gill, hepatopancreas, gonad, and mantle tissues, with structural damage observed at the higher concentration.
Tissue-Specific Biomarker Responses in the Blue Mussel Mytilus spp. Exposed to a Mixture of Microplastics at Environmentally Relevant Concentrations
Researchers exposed blue mussels to an environmentally relevant mixture of polyethylene and polypropylene microplastics at three concentrations and examined tissue-specific responses over 10 days of exposure and 10 days of depuration. They found that microplastics triggered different antioxidant responses in the digestive gland versus the gills, with some evidence of DNA damage and immune system changes. The study highlights that even low, environmentally realistic concentrations of microplastics can induce measurable biochemical stress in marine bivalves.

Researchers investigated microplastic contamination in sediment and its effects on Indian green mussels (Perna viridis) near Chennai, India. They found that fibers were the most common microplastic type, and that ingested microplastics caused structural damage to gill tissue, hemocyte infiltration, and oxidative stress in the mussels, indicating significant biological impacts from environmental microplastic exposure.
Mussel digestive gland as a model tissue for assessing xenobiotics: An overview
This review examines the mussel digestive gland as a model tissue for biomonitoring xenobiotic contamination in marine environments, covering biomarkers from molecular to cellular levels. The study highlights that mussels' ability to accumulate contaminants, including microplastics, at concentrations higher than surrounding water makes their digestive glands particularly useful for assessing environmental pollution and its biological effects.
Dynamic of small polyethylene microplastics (≤10 μm) in mussel's tissues
Mussels were exposed to a single dose of irregularly shaped HDPE particles (mainly ≤10 μm) followed by 7-day depuration, with particles accumulating in the digestive gland and gills over time and smaller fractions (≤4 μm) showing translocation from the digestive system to the gills. The study demonstrates that the smallest microplastic fractions persist longer and translocate to secondary tissues in bivalves.
Cellular and tissue-level responses of mussels (Mytilus edulis) to aged polyethylene terephthalate (PET) micro- and nanoplastic particles
This study exposed mussels to environmentally realistic concentrations of aged PET micro- and nanoplastics and found measurable cellular damage even at the lowest doses tested. The plastic particles caused inflammation, oxidative stress, and tissue changes in the mussels' digestive systems. Since mussels are a common seafood and are often eaten whole, these findings are relevant to understanding human microplastic exposure through shellfish consumption.
