Risk Analysis of Microplastic Exposure Through Consumption of Anadara Granosa at Coastal Area
AI summary Read the abstract
Researchers analyzed microplastic contamination in blood clams from a coastal area in Indonesia, finding 68 microplastic particles across samples, predominantly in line shapes with blue coloring. The risk assessment determined that current exposure levels through clam consumption remain within safe limits, though the study notes that microplastic exposure in humans occurs through multiple routes beyond seafood consumption alone.
Plastic waste is starting to threaten marine waters, especially microplastics. This micro-sized plastic can be consumed by marine biota. The accumulation of microplastics in the bodies of marine biota can threaten humans who consume them. The purpose of this study was to analyze the risk level of microplastic (polystyrene) exposure through the consumption of blood clams in the coastal area of Pao Village, Tarowang District, Jeneponto Regency. This type of research is a descriptive analysis with the Environmental Health Risk Analysis (EHRA) approach. The samples in this study were 30 respondents and 125 blood clams (anadara granosa). Data were obtained by interview using a questionnaire, identifying MPs in shells in the laboratory, and identifying polymer types using FTIR-spectroscopy. The results showed that 68 MPs of microplastics were found in blood clams (anadara granosa) samples. The dominant shapes were lines and blue. The types of polymers from the FTIR results are Polystyrene (PS), Low-density polyethylene (LDPE), Polyvinyl chloride (PVC), and Polyethylene (PE). The average non-carcinogenic daily intake (Intake) is 0.00012 mg/kg/day, the average risk level (RQ) is 0.0006, and the daily intake value is ≤0.2 (RfD Styrene), so it is said to be safe and the risk level value (RQ) ≤ 1, then categorized as the risk of exposure to MPs in humans through consumption of blood clams is still categorized as safe. The route of exposure to MPs in humans is not only through blood clams, so efforts to control the risk of exposure to MPs in humans are still needed.

Characteristics, Abundance and Polymer Type of Microplastics in Anadara granosa (Blood Clam) from Coastal Area of Palopo City
AI summary Read the abstract
Researchers analyzed microplastic contamination in blood clams collected from coastal waters near Palopo City, Indonesia. As filter feeders, these bivalves are particularly vulnerable to ingesting microplastic particles, and the study documented the abundance and polymer types found in their tissues. The findings raise concerns about human exposure to microplastics through the consumption of commonly harvested shellfish.
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.

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.
