Impact of seasonal variations on microplastic accumulation and characteristics in sandy beaches of Sichang Island, the inner Gulf of Thailand
Researchers measured microplastic abundance in beach sediments on Sichang Island in the Gulf of Thailand across dry and wet seasons, finding that seasonal monsoon winds and currents strongly affected where plastics accumulated — increasing contamination on exposed windward beaches and reducing it on sheltered leeward ones. Polypropylene was the most common polymer found, and smaller microplastic particles became less abundant after the wet season, possibly dispersed further by wave action. The work highlights how local geography and seasonal weather patterns shape where microplastics concentrate along coastlines.
Microplastic accumulation dynamics in two Mediterranean beaches with contrasting inputs
Researchers monitored microplastic accumulation dynamics on two Mediterranean beaches with contrasting human pressures over multiple seasons, finding that beaches near urban areas accumulated MPs faster and showed greater concentration variability. Short-term accumulation events tied to storms and wind patterns were identified as key drivers of MP deposition.
Seasonal variation in the abundance of marine plastic debris in the estuary of a subtropical macro-scale drainage basin in South China
Plastic debris was collected from 25 beaches in Hong Kong during wet and dry seasons, with significantly higher abundance in summer. The seasonal pattern was attributed to increased rainfall and runoff during summer, which flushes land-based plastic waste into coastal areas, highlighting stormwater as a key driver of beach plastic pollution.
Spatial and seasonal distribution of microplastics on sandy beaches along the coast of the Hengchun Peninsula, Taiwan
Researchers conducted the first survey of microplastic pollution on beaches along the Hengchun Peninsula in Taiwan, sampling eight beaches in two seasons and finding microplastics in all locations with higher abundances in summer. The results provide baseline contamination data for a major tourist coastal area and document seasonal variation in beach microplastic accumulation.
Why sampling season and location matter for monitoring micro and mesoplastics on the beach
Researchers analyzed microplastic pollution across 11 marine beaches in Latvia over four seasons from autumn 2022 to summer 2023, demonstrating how sampling season and location significantly influence measured pollution levels in the Baltic Sea region due to seasonal weather patterns and local hydrodynamics.
Long-term observations of microplastic and mesoplastic distribution on sandy beaches in north-east Taiwan: Impact of typhoons on spatial and temporal variability
Using two decades of sampling data, researchers tracked long-term trends in microplastic and mesoplastic distribution on sandy beaches, finding steady increases in particle abundance over time with notable accumulation hotspots linked to ocean current patterns.
The seasonal distribution characteristics of microplastics on bathing beaches along the coast of Qingdao, China
Researchers surveyed microplastic pollution at six bathing beaches along the coast of Qingdao, China, across winter and summer seasons. Microplastic abundance in both seawater and sediment was significantly higher in summer, and concentrations increased from east to west, consistent with coastal current patterns. The study suggests that human recreational activity and urbanization contribute to higher microplastic levels at these popular beach destinations.
Microplastics in Marine Sediments in Eastern Guangdong in the South China Sea: Factors Influencing the Seasonal and Spatial Variations
This study investigated seasonal variation in microplastic abundance in marine sediments across multiple-use zones of Eastern Guangdong in the South China Sea, finding that seasonal and spatial patterns were influenced by hydrodynamic conditions, rainfall, and proximity to human activity.
Microplastics in equatorial coasts: Pollution hotspots and spatiotemporal variations associated with tropical monsoons
Researchers systematically quantified microplastic pollution in beaches and mangroves across equatorial Singapore and found that seasonal monsoon patterns strongly influenced contamination levels. Wind speed was positively correlated with microplastic abundance, suggesting transboundary transport of particles, while rainfall appeared to wash surface microplastics away. The study found that coastal microplastic concentrations in Singapore have increased by two orders of magnitude since 2014, with mangroves acting as effective accumulation hotspots.
The Effects of Rainfall Events on the Composition and Diversity of Microplastics on Beaches in Xiamen City on a Short-Term Scale
Short-term monitoring around rainfall events on Xiamen City beaches found that precipitation increased the number and diversity of microplastics in beach sediments, pointing to storm runoff as a major delivery mechanism.
Influence of monsoon seasonality and tidal cycle on microplastics presence and distribution in the Upper Gulf of Thailand
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.
Spatio-temporal comparison of neustonic microplastic density in Hong Kong waters under the influence of the Pearl River Estuary
Spatial and temporal surveys of microplastic density in Hong Kong surface waters found elevated concentrations near the Pearl River Estuary and seasonal variation linked to river discharge. The study provides empirical evidence that river outflow from China's Pearl River is a significant driver of coastal microplastic distribution in Hong Kong waters.
Spatiotemporal variations in rural and urban beach microplastics accumulation in sediment along Sarangani Bay Protected Seascape, Mindanao, the Philippines
Researchers measured microplastic contamination in beach sand at urban and rural sites along a protected seascape in the Philippines across wet and dry seasons. They found significantly higher microplastic levels during the wet season, particularly at urban beaches, likely because rainfall washes more plastic debris from land into waterways. The most common plastics identified were polyester and polyethylene, suggesting sources from textiles and common consumer packaging.
Small-scale temporal and spatial variability in the abundance of plastic pellets on sandy beaches: Methodological considerations for estimating the input of microplastics
A beach survey found high small-scale variability in plastic pellet abundance across the intertidal zone, driven by tidal cycles, wind, and sampling method. These findings have important methodological implications — researchers need standardized sampling designs to generate reliable estimates of microplastic contamination on beaches.
Microplastics and plastisphere at surface waters in the Southwestern Caribbean sea
Researchers surveyed microplastic pollution at the surface waters of two marine-coastal areas in the Southwestern Caribbean Sea across wet and dry seasons. The study found higher microplastic concentrations during the rainy season, likely due to increased runoff carrying land-based plastic waste into the ocean. Evidence indicates that seasonal weather patterns and local land use significantly influence microplastic distribution in coastal marine environments.
Can microplastics in offshore waters reflect plastic emissions from coastal regions?
Researchers found a significant negative correlation between coastal plastic discharge amounts and offshore microplastic abundance in Chinese waters, indicating that hydrodynamic conditions rather than proximity to pollution sources primarily determine microplastic distribution.
