IPB University Expert: Microplastics Contaminating Nearly All Indonesian Waters
A recent study has indicated that microplastic contamination is a considerable environmental issue in Indonesian waters. Reports suggest that Indonesia ranks second globally, following China, in terms of microplastic pollution levels.
Research Overview
The research was conducted by Professor Etty Riani from the Department of Aquatic Resources Management at IPB University. Findings reveal that nearly all Indonesian waters are contaminated with microplastics and even nanoplastics, with heightened levels of contamination observed in densely populated areas such as Jakarta Bay.
Sources of Microplastics
Microplastics are derived from the breakdown of various products, including clothing, food and beverage packaging, household items, and personal care products. These items degrade over time into smaller particles, eventually transforming into microplastics and subsequently into nanoplastics.
Environmental and Health Risks
The decomposition of plastic materials can lead to the release of hazardous additives into the environment, posing risks to local wildlife and ecosystems. Additionally, microplastics may act as carriers for toxic substances, which could enter the food chain and ultimately impact human health.
Causes of Pollution
The study attributes ongoing pollution to human activities, primarily the improper disposal of plastic waste, which frequently ends up in rivers and oceans. The lightweight characteristics of plastic facilitate its transport by wind and water currents, thereby exacerbating contamination issues.
Need for Comprehensive Research
Professor Riani has emphasized the importance of conducting comprehensive research on microplastics, highlighting the need for advanced laboratory standards and equipment to accurately assess contamination levels. She noted that while caution is advisable, the presence of microplastics cannot yet be classified as pollution, as there are currently no quality standards for microplastics in aquatic environments in Indonesia or in any developed countries.
Quality Standards and Regulations
According to Professor Riani, the existing quality standards in Indonesia, which do not address microplastics, have been adapted from regulations in other nations. The establishment of national standards requires extensive toxicology testing, including evaluations of aquatic organisms, to ensure ecological safety.
Conclusion
In summary, due to the absence of recognized quality standards for microplastics, Professor Riani suggests that the term “contamination” is more appropriate than “pollution” at this time.
