Environmental Health Risk Analysis of Microplastics Pollution Due to Bullet Tuna (Auxis Rochei) In Coastal Communities in Banyuwangi Regency
AI summary Read the abstract
Researchers found tiny plastic particles (microplastics) in every bullet tuna sample tested from an Indonesian fishing community—and frying the fish only removed about 75% of them, not all. For most people, occasional consumption seems relatively low-risk, but people who eat a lot of this fish regularly could face plastic exposure levels high enough to raise long-term health concerns, including cancer risk. This highlights why reducing ocean plastic pollution matters directly for the safety of seafood many communities rely on daily.
Introduction: Microplastic pollution has become a global environmental concern that threatens both marine ecosystems and human health, particularly in coastal regions with high fish consumption rates. This study aimed to analyze microplastic contamination in bullet tuna (Auxis rochei) consumed by coastal communities in the Muncar District, Banyuwangi Regency, Indonesia, and to evaluate its potential health risks using the Hazard Quotient (HQ) approach. Methods: Fish samples were collected from local fish auction sites and analyzed in both raw and fried forms using FTIR spectroscopy and microscopy. Results: The results revealed microplastic contamination in all samples, with a total concentration of 0.05 particles per gram, predominantly composed of polyethylene (PE) polymer. Frying reduced the microplastic abundance by 75%, although complete elimination was not achieved. Risk assessment indicated an average HQ of 0.47985, with a maximum value of 30.660, exceeding the safe threshold (HQ > 1) in extreme consumption scenarios. Statistical analysis showed a significant correlation (p < 0.05) between microplastic concentration and carcinogenic intake, indirectly increasing the HQ. Conclusion: These findings suggest that the consumption of Auxis rochei contributes to carcinogenic exposure and poses long-term health risks, especially among coastal populations with high consumption. This study underscores the urgent need for effective plastic waste management, food safety monitoring, and public education to safeguard marine food security and community health.

Researchers analyzed microplastic contamination in fresh and processed pindang fish from the coastal community of Muncar, Banyuwangi, Indonesia, and surveyed local consumption habits. They found microplastics present in fish samples and used statistical analysis to explore potential correlations with health outcomes reported by local residents. The study highlights concerns about dietary microplastic exposure in communities that depend heavily on seafood.

AI summary Read the abstract
This Indonesian study detected microplastic contamination in the digestive tracts of bullet tuna (Euthynnus affinis) caught in local waters. Microplastics were found in fish from all sampling locations, with fiber fragments being most abundant. The findings raise food safety concerns given that bullet tuna is a commercially important species consumed in Indonesia.
Microplastic Abundance and Characteristics in Digestive Tract of Fish Tongkol Euthynnus affinis from Coastal Area of Ampenan, Mataram
AI summary Read the abstract
Scientists checked tuna caught off the coast of Mataram, Indonesia and found tiny plastic bits (microplastics) in every fish's gut, averaging about 2 pieces per fish — mostly tiny black fibers, likely shed from things like synthetic clothing or fishing nets. Since tuna is a popular food fish, this suggests some of that plastic could end up on our plates too, though more research is needed to know exactly how much risk this poses to human health.
