Summary

Researchers surveyed the waters and green mussels along the Kalirejo coast in East Java, Indonesia, and found microplastics in all samples, with higher concentrations at shallower depths. Polyethylene fragments were the most common type, and there was a strong correlation between microplastic levels in the water and in mussel tissues, indicating the animals absorb plastics directly from their environment. The findings raise concerns about both ecological impacts and potential health risks from consuming contaminated shellfish in this major mussel farming region.

Microplastic pollution is a significant global environmental concern affecting marine ecosystems and human health. This study investigated the presence and abundance of microplastics in the waters and green mussels (Perna viridis) of the Kalirejo coastal area in East Java, Indonesia, a region known for extensive mussel cultivation. The results showed that microplastics were present in all water and mussel samples, with higher concentrations at shallower depths. Fragments were the most prevalent microplastic type, followed by fibers and films, with polyethylene (PE) identified as the dominant polymer. A strong positive correlation between microplastic concentrations in water and mussel tissues indicates direct environmental uptake. These findings highlight widespread microplastic contamination in the Kalirejo coastal area, raising concerns about environmental impacts and health hazards associated with consuming contaminated shellfish.
