Spatial and vertical distribution of microplastics in mangrove sediment in the southern Philippines
This study mapped microplastic contamination in the sediments of three mangrove forests in Mindanao, Philippines, finding particles at all sites with counts ranging from 83 to 2,250 items per kilogram depending on location. Fragment shapes dominated near one river mouth while fibers dominated at a coastal site, and polypropylene was the most common polymer overall. Microplastic levels and types appeared linked to local economic activity, fishing, and waste management practices. The findings provide baseline data for protecting these ecologically important coastal ecosystems.
Spatial Distribution of Microplastics Abundance Along Selected Beaches in Kelantan, Malaysia
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.
Physical characterization of litter and microplastic along the urban coast of Cagayan de Oro in Macajalar Bay, Philippines
