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 ? = 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).
