Seasonal variation in the abundance of microplastics in three commercial bivalves from Bandon Bay, Gulf of Thailand
AI summary Read the abstract
Researchers examined microplastic contamination in three types of commercially harvested shellfish from Bandon Bay in Thailand across different seasons. They found that microplastic levels were significantly higher during the dry season, with oysters containing the most particles. The study suggests that seasonal conditions and proximity to fishery activities influence how much microplastic accumulates in seafood.
This study investigated the abundance of microplastics in three commercial bivalves found at Bandon Bay. Spatial-temporal differences in the concentration of microplastics were evaluated during the dry and wet seasons. The results showed that the highest abundance of microplastics in oysters, blood cockles, and green mussels was observed in fishery and aquaculture areas during the dry season, with 1.42 particles/g (w/w), 1.01 particles/g (w/w) and 0.87 particles/g (w/w), respectively. Microplastics were more abundant during the dry season compared to the wet season (p < 0.05), with fibre being the predominant shape and black being the major colour of particles. Cellophane was the most common type of polymer in all bivalves. This result is an important reference for understanding the status of microplastics in three commercial bivalves during different seasons and in different human activities, which should aid in understanding the sources of microplastics in Bandon Bay.

Researchers investigated seasonal variations in microplastic contamination in estuarine sediments from an urban canal in Phuket, Thailand. They found microplastic abundance was higher in the dry season than the rainy season, with rayon and polyester being the most common polymer types, suggesting that seasonal hydrological patterns and human activities both influence microplastic distribution in urban estuaries.
Microplastics in commercial bivalves from the upper gulf of Thailand: Do location, season, and species ecology matter to human dietary exposure?
AI summary Read the abstract
Bottom-dwelling shellfish like clams and cockles from Thailand contained more microplastic bits than mussels or oysters that live suspended in the water, likely because they pick up more debris from the seabed. Some samples also contained a particularly toxic type of plastic (PVC), meaning where and what type of shellfish you eat may affect how much plastic you're actually consuming.

Influence of monsoon seasonality and tidal cycle on microplastics presence and distribution in the Upper Gulf of Thailand
AI summary Read the abstract
Researchers surveyed microplastic pollution around Si Chang Island in the Gulf of Thailand across different monsoon seasons and found that seasonal weather patterns strongly influence microplastic abundance and distribution. Evidence suggests that UV exposure during dry seasons fragments plastic waste on land, which is then washed into the ocean by heavy rains during the wet season. The findings highlight how tropical climate cycles drive microplastic contamination in Southeast Asian coral reef areas.
