Occurrence and abundance of microplastics in surface water of Songkhla Lagoon

Researchers surveyed microplastic contamination in the surface waters of Songkhla Lagoon in Thailand and found microplastics at all sampling sites. Small fibers under 500 micrometers were the most abundant type, with rayon and polyester being the dominant polymer materials. The findings indicate that this important coastal lagoon system is widely affected by microplastic pollution from surrounding urban and industrial sources.

Integration of microplastics and heavy metals in the potential ecological risk index: Spatial pollution assessment of sediments in the inner Gulf of Thailand

Researchers assessed the spatial distribution of microplastics and heavy metals in surface sediments of the inner Gulf of Thailand, finding an average of nearly 1,400 microplastic pieces per kilogram with the highest concentrations near river mouths. They developed an integrated ecological risk index combining microplastic and heavy metal contamination, revealing that areas near river estuaries face moderate to considerable combined pollution risk. The study demonstrates the importance of evaluating microplastics alongside other contaminants for comprehensive environmental risk assessment.

Spatiotemporal dynamics and tidal transport of microplastics in the tropical waters of the Gulf of Thailand

Researchers tracked microplastic contamination from the Chumphon River through the coastal Gulf of Thailand, including in farmed green mussels, finding that river systems carried higher microplastic loads than coastal waters. In the water column, low-density polymers dominated near the surface while high-density plastics increased with depth, and fibers made up 95% of particles in river water. Green mussels contained shorter fibers matching their surrounding environment, confirming that freshwater runoff from human activities is a major source of coastal microplastic pollution.
