Mussels as Bioindicators:
Mussels are being used as bioindicators to monitor microplastic and chemical pollution in the Saronic Gulf of Greece. Mussels are bivalve mollusks ( shell-bearing invertebrates with two hinged shells). They are found in both marine (family Mytilidae) and freshwater (family Unionidae) environments.
They occur worldwide, especially in cooler seas, and are an important component of coastal biodiversity.Mussels are used as bioindicators because they are sessile, filter-feeding organisms that accumulate contaminants like heavy metals, microplastics, and other pollutants in their tissues, providing a record of water quality over time. Their wide distribution and ability to reflect the presence of pollutants make them valuable for monitoring both freshwater and marine environments for pollution, including chemical and biological hazards.
