Analysis of Microplastic Content in Blood Shells (Anadara Granosa) in Belawan Waters in Medan City, North Sumatra Province

The Alarming Reality of Microplastic Pollution in Belawan Waters

Microplastic has become a pressing environmental issue worldwide, including in the waters of Belawan, Medan City, North Sumatra Province. The high production of plastic waste in these waters has led to microplastic contamination, which accumulates in the bodies of blood shells, a popular and economically valuable type of seafood. This study aims to analyze the shape, number of microplastics, polymers, and estimated microplastic consumption for humans who consume blood shells in Belawan waters.

Background and Significance of the Study

Blood shells, or Anadara granosa, are a type of seafood that is widely consumed in Medan City. However, the increasing presence of microplastics in these waters poses a significant threat to human health and the marine ecosystem. Microplastics can enter the human body through seafood, where they can trigger various health problems, including inflammation and potential risk of cancer. Therefore, it is essential to investigate the microplastic content in blood shells and its potential impact on human health.

Methodology and Data Collection

Field data collection was carried out in January 2023 by collecting shells and sediment samples in three different locations: ports, open sea, and mangrove forests. From each location, 10 blood shells were taken and about 1 kg of sediment. Microplastic analysis of blood shell samples was done using a 10% KOH solution, followed by microplastic identification using a stereo microscope.

Results and Analysis

The analysis shows that the microplastic shapes found in blood shells include fiber, fragments, films, and pellets. The microplastic abundance in blood shells at stations I, II, and III are 64.04 particles/dry weight, 44.19 particles/dry weight, and 54.29 particles/dry weight, respectively. The results of the FTIR test revealed that the types of polymers detected are polypropylene, polystyrene, and polyethylene. The estimated number of microplastic consumed by the people of Medan through blood shells reaches 16.90 ± 2.53 MP per year.

Implications and Recommendations

The discovery of microplastic in blood shells provides a worrying picture of the impact of environmental pollution on marine resources. Blood shells as one of the most consumed seafood have the potential to channel microplastic into the human food chain. Microplastic consumption can negatively affect human health, although the impact is still the subject of further research.

To reduce this risk, it is essential for the community and authorities to increase awareness about the management of plastic waste and the need for a tighter policy in controlling pollution in the waters. Through coordinated efforts, such as coastal cleaning programs, education to the community, and the development of plastic recycling technology, we can help reduce the number of microplastics that pollute the waters and protect the health of the community and marine ecosystems.

Conclusion and Future Directions

This study highlights the urgent need to address the issue of microplastic pollution in Belawan waters. The results of this study provide valuable insights into the microplastic content in blood shells and its potential impact on human health. Further research is needed to investigate the long-term effects of microplastic consumption on human health and to develop effective strategies for reducing microplastic pollution in the waters.
