Analysis of Microplastic Intake by Human through Red Kurisi Fish (Nemiptus Japonicas) and Mackerel (Rastrelliger Sp) Consumption in the Coastal Area Community of Tamasaju Village, North Galesong, Takalar Regency
AI summary Read the abstract
Researchers measured microplastic contamination in two fish species consumed by coastal communities in South Sulawesi, Indonesia, and estimated human microplastic intake through fish consumption. The findings suggest that local fish consumption is a meaningful exposure pathway for microplastics in this community.
Plastic waste has become one of the most serious threats to the marine environment. Among the plastic waste that is of particular concern are microplastics because of their small size. The purpose of this study was to analyze the level of microplastic intake through fish consumption in the coastal area of Tamasaju Village, North Galesong, Takalar Regency. This research is a type of qualitative research with a descriptive approach. The samples in this study were 30 respondents and 20 fish with the types of mackerel and red kurisi fish. Data obtained by interview using questionnaires, identification of microplastics in fish in the laboratory, and identification of polymer types using FTIR spectroscopy. The results showed that the total number of microplastics found was 18 particles. The type of microplastic found was a line shape with different color and size variations, with the blue line dominating, namely 77.77%. The average concentration of microplastics found in fish was 3.1 mg/kg, with polystyrene polymer content. It is known that the average intake of non-carcinogenic microplastics by the community is 0.04 mg/kg/day (non-carcinogenic) and as much as 0.02 mg/ kg/day (carcinogenic). This shows that the intake of microplastics by humans through fish consumption is still categorized as safe.

The Comparative Analysis of Microplastic Contamination in Kembung (Rastrelliger sp) and Kurisi Fish (Nemipterus nemurus) from Coastal Waters of Mangindara, Indonesia
AI summary Read the abstract
Researchers found tiny plastic fragments called microplastics in every single fish sample they tested from a polluted coastal village in Indonesia, with kurisi fish containing even more plastic bits than kembung fish. Since these fish are regularly caught and eaten by local communities, this means people may be unknowingly consuming plastic particles along with their seafood, highlighting why cutting back on single-use plastics and improving waste management matters for both ocean health and what ends up on our plates.

Environmental Health Risk of Microplastics Due to Consumption of Fish and Shellfish in the Coastal Area
AI summary Read the abstract
Researchers assessed the health risk of microplastics in fish and shellfish consumed by people in a coastal area of Takalar, Indonesia. All samples had risk quotient values below the safety threshold, indicating that microplastic levels in the seafood were within acceptable limits for human consumption at the time of sampling. The study provides baseline data for monitoring microplastic contamination in commercially important coastal fisheries.
