Risk Analysis of Microplastic in Fish (Nemiptus Japonicas & Rastrelliger Sp.) in Communities in the Coast Area of Tamasaju, Galesong Takalar

Abstract

Plastic waste has become one of the most serious threats to the marine environment. Among the plastic waste of special concern is microplastic because of its small size. This study aimed to analyze the level of risk of microplastic exposure through fish consumption in communities in the coastal area of Tamasaju Village, North Galesong District, Takalar Regency. Microplastic abundance found as many as 18 particles, microplastic types found are the shape of a line or fiber with different color and size variations. Blue fiber dominates at 77.77%. The average microplastic concentration (C) in fish is 0.2 mg/kg. The respondents interviewed were 30 people and mostly fishermen. Average intake rate (R) ± 155 grams/day, Average frequency of exposure (FE) of fish consumption ± 190 days/year, Average duration of exposure (Dt) of fish consumption ± 39 years and. Average respondent's weight (Wb) ± 58 kg. The average Non-Carcinogenic Intake Rate in fish consumption is 0.004754 mg/kg/day and the average Carcinogenic Intake Rate in fish consumption is 0.009328 mg/kg/day. The results of calculations with one-way ANOVA obtained P-Value = 0.009867 <value α = 0.05, then there is a strong relationship with microplastic concentration, intake rate, frequency of exposure, and duration of exposure to Intake Rate or Risk (RQ).

Microplastic Pollution in Waters and its Impact on Health and Environment in Indonesia: A Review

“…Both non-carcinogenic or carcinogenic risks indicate the strong relation with the concentration (C) of microplastic in fish, intake rate (R), shelf frequency (FE), exposure duration, and weight (WE) of the respondents. 80 Based on the results of the study, microplastics were found in all feces of samples of pregnant women in the working area of Puskesmas Pattingalloang and Jumpandang Baru, Makassar. Microplastics were found from thirty stool samples ranging from 5-21 microplastics with the types of fibers, fragments, and films due to fish consumption.…”
