“…Solid waste was dominated by plastic. Therefore, it is necessary to determine the level of health risk of consuming microplastic-containing marine biota ( 14 ). Therefore, in this study, evidence of marine biota being contaminated with microplastics will be reviewed, and the level of risk of microplastics in the marine ecosystem to human health will be determined.…”

Background: The increasing accumulation of plastic waste is the most serious threat to the marine ecosystem. People who still have the habit of disposing of solid waste, especially plastic-type waste, in the marine environment have led to the discovery of microplastic content in various marine biota such as fish and shellfish. We aimed to assess the environmental health risks of microplastics due to consumption of marine life in the coastal area. Methods: We used an observational method with the Environmental Health Risk Assessment (EHRA) design to analyze the health risks of humans consuming fish and shellfish containing microplastics. This research was conducted in the coastal area of Takalar Regency, Indonesia in 2022. The samples used consisted of human (n = 30) and marine biota (fish, n=20; shellfish, n=20) samples. The data were obtained from observations, physical measurements of biota, laboratory tests, polymer type identification by Fourier Transform Infrared (FTIR) spectroscopy, and microscopy. Results: The average concentration of microplastics containing styrene compounds in shellfish was 2.01 mg/kg. The abundance of MPs in the fish and shellfish samples was 0.01 particles/g or 10 particles/kg in fish and 7 particles/individual in shellfish. The MPs were found in line, fragment, film, and pellet forms, with different size and color variations. The average MPs exposure risk level (RQ value) for both fish and shellfish was 0.02. Conclusion: All samples had RQ values < 1, which means that the microplastic-containing tofu shellfish were still safe for consumption by people living in the Takalar coastal area.

“…Microplastics, also known as simply 'particles <5mm in size,' are the byproducts of plastic degradation, according to Moore et al (2001). Polidoro et al (2022) found that microplastics can be hazardous to the environment and human health due to their chemical composition. According to Yu et al (2020), microplastics include a significant quantity of carbon, which is either inert or difficult to react with and decomposes slowly.…”

Due to exposure to their chemical components, microplastics (<5mm) are byproducts of plastic degradation that can be harmful to the environment and human health. Microplastics, one of which is in the watershed, will be present due to human activity-related irresponsible discharge of plastic waste into the environment. The watershed's use of the land has an impact as well. This research aims to analyze how different land use patterns affect the types of microplastics that have been observed. This research's methodology is quantitative and includes techniques for spatial, statistical, and chemical analysis. In the Ciujung watershed, polyethylene (PE), polypropylene (PP), and polyester microplastics were observed according to the study's findings. The type of microplastic observed was likely brought on by local activities. On agricultural land, plantations, and settlements, fertilization, irrigation, and other human activities may contribute to microplastic contamination. The vast amount of plastic bags and bottles that are left behind are either immediately dumped into the Ciujung Watershed by the locals or carried away by the flow of activities on the land, where they eventually degrade into microplastics.

The ubiquitous nature of microplastics (MPs) in nature and the risks they pose on the environment and human health have led to an increased research interest in the topic. Despite being an area of high plastic production and consumption, studies on MPs in the Middle East and North Africa (MENA) region have been limited. However, the region witnessed a research surge in 2021 attributed to the COVID-19 pandemic. In this review, a total of 97 studies were analyzed based on their environmental compartments (marine, freshwater, air, and terrestrial) and matrices (sediments, water columns, biota, soil, etc.). Then, the MP concentrations and polymer types were utilized to conduct a risk assessment to provide a critical analysis of the data. The highest MP concentrations recorded in the marine water column and sediments were in the Mediterranean Sea in Tunisia with 400 items/m 3 and 7960 items/kg of sediments, respectively. The number of MPs in biota ranged between 0 and 7525 per individual across all the aquatic compartments. For the air compartment, a school classroom had 56,000 items/g of dust in Iran due to the confined space. Very high risks in the sediment samples ( Er i > 1500) were recorded in the Caspian Sea and Arab/Persian Gulf due to their closed or semi-closed nature that promotes sedimentation. The risk factors obtained are sensitive to the reference concentration which calls for the development of more reliable risk assessment approaches. Finally, more studies are needed in understudied MENA environmental compartments such as groundwater, deserts, and estuaries.
