ClearSpatiotemporal microplastic occurrence study of Setiu Wetland, South China Sea
A bimonthly sampling study across Setiu Wetland in the South China Sea found microplastics in both surface water and sediment throughout the year, with spatiotemporal variation linked to tidal activity, rainfall, and proximity to human settlement.
Seasonal Distribution, Composition, and Inventory of Plastic Debris on the Yugang Park Beach in Zhanjiang Bay, South China Sea
Researchers surveyed seasonal distribution and composition of plastic debris at Yugang Park Beach in South China Sea, finding significant variation across seasons and tidal zones, with single-use plastics from tourism and fishing activities as the primary sources.
Microplastics in Surface Waters and Sediments from Guangdong Coastal Areas, South China
Microplastics were detected in surface waters and sediments across coastal areas of Guangdong Province in South China, with higher concentrations near urban centers and river mouths reflecting the region's dense population and industrial activity.
Temporal and Spatial Distribution of Microplastics in a Coastal Region of the Pearl River Estuary, China
Researchers found that microplastic abundance in the Pearl River Estuary coastal region was 1.85-fold higher during the rainy season than the dry season, with concentrations decreasing from river to estuary to open sea. Fibers and fragments dominated, with gray, white, and green particles most common across sampling sites.
Distribution pattern and influencing factors for the microplastics in continental shelf, slope, and deep-sea surface sediments from the South China Sea
Researchers investigated microplastic pollution in surface sediments across the continental shelf, slope, and deep-sea floor of the northern South China Sea. The study found an average abundance of about 131 particles per kilogram, with distribution patterns influenced by ocean currents, water depth, and proximity to river inputs.
Microplastic occurrence in the northern South China Sea, A case for Pre and Post cyclone analysis
Researchers analyzed microplastic contamination in the northern South China Sea before and after a cyclone, finding that the storm event significantly altered microplastic distribution patterns in both coastal seawater and sediments.
Impact of typhoon events on microplastic distribution in offshore sediments in Leizhou Peninsula of the South China Sea
Researchers studied how typhoon events redistribute microplastics in offshore sediments around the Leizhou Peninsula in the South China Sea. The study found that monsoon and typhoon conditions significantly altered microplastic distribution patterns, with polypropylene and high-density polyethylene dominating across seasons, demonstrating how extreme weather events can reshape contamination patterns.
Hydro-sedimentary conditions shape the microplastic occurrence in sediments of the Pearl River Estuary (China)
A field study of the Pearl River Estuary in southern China found microplastic concentrations in sediments ranging from 4 to 220 particles/kg, with higher abundance in nearshore zones, and identified hydrodynamic conditions and proximity to urban areas as the main drivers of spatial variation.
Distribution and environmental risk assessment of microplastics in continental shelf sediments in the southern East China Sea: A high-spatial-resolution survey
Researchers conducted a high-spatial-resolution survey of microplastics in surface sediments across the southern East China Sea continental shelf, finding omnipresent contamination dominated by polyethylene fibers and fragments, with concentrations elevated near urban coastal areas.
Microplastic Contamination on the Beaches of South China
Researchers surveyed microplastic contamination across 14 beaches along the South China coast, finding microplastics ubiquitously present in sandy sediments, predominantly as small fragments under 1 mm, with distribution patterns linked to coastal urbanization and ocean current dynamics.
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.
Spatial-temporal distribution of microplastics in surface water and sediments of Maozhou River within Guangdong-Hong Kong-Macao Greater Bay Area
Researchers mapped the spatial and seasonal distribution of microplastics along the Maozhou River in China's Greater Bay Area. They found that microplastic concentrations were highest near industrial areas and downstream sites, with dry season levels significantly exceeding wet season levels. The dominant polymer types were polyethylene and polystyrene, and metals were detected on the surfaces of recovered microplastic particles.
Seasonal variation of diversity, weathering, and inventory of microplastics in coast and harbor sediments
Seasonal variation in microplastic diversity, weathering degree, and abundance was characterized in coastal and harbor sediments along the southwestern coast of Taiwan, finding harbor sites more contaminated than coastal areas and summer monsoon rains driving seasonal fluctuations.
Occurrence of microplastics in the seawater and atmosphere of the South China Sea: Pollution patterns and interrelationship
Researchers investigated microplastic pollution in both seawater and the atmosphere of the South China Sea, revealing distribution patterns and an interrelationship between marine and airborne microplastic contamination in the region.
Occurrence and distribution of microplastics in commercial fishes from estuarine areas of Guangdong, South China
Researchers analyzed the abundance, characteristics, and spatial distribution of microplastics in six commercial fish species from estuarine areas of Guangdong, South China, providing quantitative data on microplastic ingestion in fish from one of China's most plastic-polluted coastal regions.
Microplastic Accumulationin Hong Kong’s MarineSediment: Spatial Pattern and Potential Sources
Researchers conducted a comprehensive survey of microplastics in marine sediments across Hong Kong, finding uneven distribution with abundance ranging from near zero to high levels in urbanized areas. Source analysis pointed to household waste, fishing activity, and stormwater runoff as primary contributors.
Spatiotemporal distribution, source identification and inventory of microplastics in surface sediments from Sanggou Bay, China
Researchers measured the spatiotemporal distribution of microplastics in surface sediments from Sanggou Bay (an aquaculture area in China) across multiple seasons and identified fishing gear and aquaculture equipment as dominant local sources, estimating total plastic inventory in the bay.
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.
Abundance and characteristics of microplastics in the mangrove sediment of the semi-enclosed Maowei Sea of the south China sea: New implications for location, rhizosphere, and sediment compositions
Microplastics were widespread in mangrove sediments of the semi-enclosed Maowei Sea in southern China, with concentrations influenced by location within the mangrove, proximity to roots, and sediment composition. The study provides new insight into how mangrove ecosystems trap and accumulate microplastics, raising concerns for the health of these ecologically important coastal habitats.
