Characteristics and Distribution of Microplastics in Surface Sediment of Selat Pulau Tuba, Langkawi, Kedah
AI summary Read the abstract
Researchers characterized the distribution and types of microplastics found in surface sediments of the Selat Pulau Tuba strait in Langkawi, Malaysia. The study found polypropylene and polyethylene as the dominant polymer types, contributing to baseline data on microplastic pollution in Malaysian coastal sediments.
This study aims to assess the characteristics and occurrence of the microplastics contamination in surface sediment of Selat Pulau Tuba, Langkawi, Kedah. Van Veen Grab Sampler was used to collect the samples of sediment. The samples were immediately preserved and analyzed using a Fourier-transform infrared spectrophotometer and a microscope to determine the presence and characteristics of microplastics. The result indicates the presents of polypropylene and polyethylene with a size of 500 µm -1000 µm and 1000 µm - 1500 µm respectively. Overall, Selat Pulau Tuba, Langkawi, Kedah has minimal pollution of microplastics in sediment.

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.
