Occurrence of microplastics in the sediments of Baseco Port area at Manila Bay, Philippines
Summary
Researchers documented microplastics in sediments at Baseco Port in Manila Bay, Philippines, finding predominantly fiber-shaped particles of polyethylene and polypropylene, highlighting seaports as significant point sources of microplastic contamination.
Abstract Microplastic in marine sediments is nowadays considered an environmental pollutant. Seaports are particularly susceptible to microplastic pollution through series of human activities occurring in these areas. In the Philippines, research on microplastics is still limited and there is still no study determining the occurrence of microplastics in the harbour of Manila Bay, Philippines. Hence, this work conducted a preliminary investigation of microplastics in the sediments of Baseco Port area, Manila Bay. Nine stations within the study region were sampled. The types of microplastics found are fragments, foam, fiber, film, pellet, and filament with an average size measurement of 1.6±1.4 mm. Results from this study suggest that anthropogenic impacts are most likely the dominant sources of accumulation and distribution of microplastics in the sediments of Baseco port. This study provides preliminary assessment of microplastics contamination in the area that may serve as important reference for further studies.

Abundance and Characteristics of Microplastic in the Selected Coastal Area of Pangasugan, Baybay City, Leyte, Philippines
Researchers surveyed microplastic contamination in coastal waters near Pangasugan, Leyte, in the Philippines, collecting samples from 20 sites. The average contamination level was 132.5 items per liter, with fibers being the most prevalent shape at 62%, and polymer analysis identified ABS, EVA, polyamide, and PET, providing baseline contamination data for this coastal area.
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.

Researchers found 2,258 microplastic particles in sediments of Panguil Bay in the southern Philippines and documented active ingestion of microplastics by three species of edible tropical bivalve molluscs, with fibers and dark-colored particles the most abundant types.
Microplastic Accumulation in Hong Kong’s Marine Sediment: Spatial Pattern and Potential Sources
Researchers conducted a comprehensive survey of microplastics in marine sediments across Hong Kong's waters. They found microplastics at every sampling site, with fibers and fragments being the most common forms and polypropylene and polyethylene the dominant plastics. The spatial patterns suggest that coastal urbanization and water circulation are key factors driving where microplastics accumulate in sediments.
