Microplastic Content in Blood Cockles (Anadara granosa) from the Coastal Waters of Tanah Merah Meranti Islands, Riau
AI summary Read the abstract
This study measured microplastic content in blood cockles (Anadara granosa) collected from coastal waters of Tanah Merah Beach in the Meranti Islands, Riau, Indonesia. Microplastics were detected across all sampling locations, with residential and industrial zones near the coast associated with higher cockle contamination levels.
This research was conducted in December 2023 to determine the type and content of microplastics in blood cockles (Anadara granosa) by taking samples from the coastal waters of Tanah Merah Beach, Meranti Islands. The sampling location was based on the purposive sampling method divided into residential areas, fishing ports, and mangrove areas. Blood cockle samples from the three locations were selected for only large sizes (2.5-3.7cm). The water quality parameters at the sampling location were measured for temperature, salinity, and pH, indicating that the coastal waters of Tanah Merah Beach are still natural habitats for blood cockles. Three types of microplastics were found in blood cockles, namely fiber, film, and fragments, with an average abundance of 56.33 particles/ind (p>0.05). Further research is needed regarding size differences and relationships with environmental parameters.

The spatial distribution and physico-chemical characteristic of microplastics in the sediment and cockle (Anadara granosa) from the coastal waters of East Java, Indonesia, and the health hazards associated with cockle consumption
AI summary Read the abstract
Researchers surveyed microplastic contamination in coastal sediments and cockles along the East Java coast of Indonesia and assessed the potential health risks from consuming the shellfish. They found microplastics, predominantly fibers and fragments, in all sediment and cockle tissue samples, with consumers potentially ingesting tens of thousands of microplastic particles per year. The findings raise concerns about dietary microplastic exposure for communities that regularly eat shellfish from these waters.
Spatial Distribution of Microplastic Contamination in Blood Clams (anadara Granosa) on the Jeneponto Coast, South Sulawesi
AI summary Read the abstract
Researchers mapped the distribution of microplastic contamination inside blood clams (Anadara granosa) harvested along the Jeneponto coast of South Sulawesi, Indonesia. The highest microplastic levels were found in clams from mangrove ecosystems and residential waterways, while river areas showed the lowest contamination. Because blood clams are widely eaten as a daily food source, these findings raise direct concerns about microplastic ingestion by local populations.
