Detection of Microplastics by Various Types of Whiteleg Shrimp (<i>Litopenaeus vannamei</i>) in the Korean Sea
Microplastic pollution in the ocean has a major impact on marine organisms, including digestive system damage and reduced growth and fertility.

| description | Microplastic pollution in the ocean has a major impact on marine organisms, including digestive system damage and reduced growth and fertility. This study investigated the amount, size, color, type, and presence of heads and intestines of microplastics by size in Litopenaeus vannamei, a type of marine organism. Microplastic analysis was performed using FTIR and digital microscopy. The number of microplastics by the size of the shrimp ranged from 1.73 to 3.8 MPs per 10 g, and the microplastic size of less than 100 μm was 77–92%, with blue showing the highest ratio. As for the type of plastic, PE and PP showed the highest ratio, and PET, PS, nylon, and PVC were found. Microplastics were found to be 11.83 MPs/10 g for heads and intestines and 3.16 MPs/10 g for samples without heads and intestines. This study adds to evidence for the presence of high levels of microplastics in the intestines and heads of shrimp. It also enhances our understanding of the need for efficient plastic waste management in the ocean and the impact of microplastics on marine biota. |
