Determination of Microplastics in Sediment of Kelantan and Pattani Bay
AI summary Read the abstract
Researchers investigated microplastic contamination in beach sediments from two bays straddling the Malaysia-Thailand border. Microplastics were detected at all sampled sites, dominated by fragments and fibers in a range of colors. The study provides baseline data on transboundary coastal plastic pollution in Southeast Asia.
Abstract This study was conducted to determine the presence of microplastics in sediment of Kelantan and Pattani Bay. Sediment samples were collected from Sri Tujuh Beach, Tumpat and Talo Kapo Beach, Pattani Bay in between May and July 2019. Microplastics were isolated from sediment samples using wet peroxide oxidation (WPO) followed by density separation. Microplastics were sorted visually according to their shapes and colors after being examined under photographed microscope. A total of 52 pieces of microplastics were identified and the most abundant particle found in this study was threadlike shape. Fourier Transform Infrared (FTIR) spectroscopy has been used to identify functional groups in the composition of microplastics. This study shows that degraded of large plastic materials to microplastics due to some factors such as weathering can impact abundance of microplastics in both places, as these locations are well known for fishing activities, industrial areas and also as tourism area.

Spatial Distribution of Microplastics Abundance Along Selected Beaches in Kelantan, Malaysia
AI summary Read the abstract
Researchers surveyed ten beaches along the Kelantan coast in Malaysia and found over 1,600 microplastic particles, averaging about 5.4 pieces per gram of sediment, with fragments being the most common type. PVC, polypropylene, and polystyrene were the dominant polymer types, and intertidal zones were the most heavily contaminated areas. The study provides important baseline data on microplastic pollution patterns along these Malaysian coastlines, which can help guide future cleanup and prevention efforts.
