ClearMonitoring of micro-plastics: a case study of shilaoren beach, Qingdao, China
Researchers measured microplastic occurrence and composition in beach sediments at Shilaoren Beach, Qingdao, China, finding 561 microplastic particles across sampling sites. The results confirm widespread microplastic contamination of beach sediments even at tourist beaches, adding to evidence of plastic pollution along Chinese coastlines.
A review of microplastic pollution in seawater, sediments and organisms of the Chinese coastal and marginal seas
This review compiled microplastic abundance and characteristics data from seawater, sediments, and marine organisms across China's coastal and marginal seas, finding widespread contamination linked to China's extensive plastic production and mismanaged waste streams.
Assessment on the pollution level and risk of microplastics on bathing beaches: a case study of Liandao, China
Researchers assessed microplastic pollution levels on bathing beaches in Liandao, China, finding an average abundance of about 135 items per kilogram of sediment. Using pollution and hazard indices, the study determined that current microplastic contamination levels pose a low health risk, though the authors note that increasing population and consumption will likely raise plastic waste levels over time.
Occurrence and distribution of microplastics on recreational beaches of Haichow Bay, China
Microplastic occurrence and distribution were examined on recreational beaches of Haichow Bay, China, a heavily visited coastal area. The study found microplastics throughout the beach environment with patterns linked to beach use intensity, wave energy, and sediment type, establishing contamination data for a tourist-frequented coastline.
Microplastic Contamination in Sediments of Xiamen Bay: Investigating Ecological Consequences
Microplastic contamination was assessed in sediments of Xiamen Bay, China, examining spatial and temporal distribution, ecological consequences for sediment biota, and human exposure pathways. Key risk factors were identified based on particle characteristics, with the study providing insights for managing microplastic impacts in this heavily urbanized coastal environment.
Rethinking the Environmental Quality of Brazilian Beaches: The Incidence of Microplastics as Indicator for Sea Water and Sand Quality
This paper proposes using microplastic levels in beach sand and seawater as indicators of beach environmental quality, arguing that current assessments in Brazil focus too narrowly on microbial contamination. The authors present evidence that microplastic contamination poses health risks to swimmers and coastal communities that should be incorporated into beach quality standards.
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 pollution in Chinese bays: Sampling method comparisons, key drivers, and economic influence
Researchers compiled microplastic data from over 300 sampling stations across 13 bays in China and compared three different water sampling methods. They found that microplastic distribution was heterogeneous across bays and that sampling method significantly affected measured abundance, though not the types of polymers detected. The study also found a positive correlation between regional economic development and microplastic pollution levels, suggesting that human activity intensity is a key driver of coastal contamination.
A novel framework-based meta-analysis for in-depth characterization of microplastic pollution and associated ecological risks in Chinese Bays
Microplastic abundance in Chinese bays ranged from 0.26 to 89,500 items/m3 in water and 15 to 6,434 items/kg in sediment, with sampling methods and geographic location identified as major drivers of observed variation. ARIMA modeling predicted that Sanggou Bay and Hangzhou Bay face the highest risk of significantly increasing future contamination.
Pollution level of microplastics in sand beaches of four locations in the coast of El Salvador, Central America
Researchers assessed microplastic pollution levels in sandy beaches at four coastal locations in El Salvador, Central America, characterizing the concentration, spatial distribution, physical and chemical properties, and potential sources of microplastics and applying the Nemerow pollution index to categorize overall contamination levels at each site.
Microplastic pollution in Chinese Rivers: A detailed analysis of distribution, risk factors, and ecological impact
Researchers aggregated data from 2,474 microplastic samples across 165 publications to assess ecological risk in Chinese rivers, finding widespread contamination with average abundance varying substantially by watershed characteristics. A revised risk assessment accounting for particle morphology and polymer toxicity raised concern levels beyond previous estimates.
A meta-analysis of methodologies adopted by microplastic studies in China
Chinese microplastic studies predominantly found irregular-shaped particles smaller than 1 mm across sediment, water, and biota, but major methodological inconsistencies in sampling, extraction, identification, and reporting units make inter-study comparisons unreliable and highlight the urgent need for standardized protocols.
Microplastics Pollution and Their Potential Impact in Marine Systems: A Case Study in Shandong Peninsula, China
Researchers surveyed microplastic pollution in marine environments around China's Shandong Peninsula, documenting contamination levels and potential impacts on the region's important fishing, aquaculture, and tourism industries.
Microplastic pollution in surface sediments of Coromandel coastline, South-East Coast, India: Diversity index, carbonyl index, pollution load index, risk fraction and MPs inventory
Researchers surveyed microplastic pollution across a 1,076-kilometer stretch of India's Coromandel coastline, using multiple indices to assess abundance, degradation, and ecological risk. They found that microplastic levels varied significantly between wet and dry seasons, with dry season samples showing higher concentrations. The study provides a comprehensive baseline assessment of microplastic contamination along one of India's most extensive coastal regions.
[Pollution Characteristics of Microplastics in Sediments of Xiamen Bay Beach].
Researchers collected layered sediment samples (0-30 cm depth) at high, mid, and low tide lines across five beaches in Xiamen Bay, China, characterising the horizontal and vertical distribution, abundance, and pollution characteristics of microplastics across 45 sediment samples.

Two-dimensional distribution and abundance of micro- and mesoplastic pollution in the surface sediment of Xialiao Beach, New Taipei City, Taiwan
Researchers systematically mapped microplastic and mesoplastic pollution across Xialiao Beach in Taiwan, recovering 1,939 particles from 80 samples and finding that the backshore contained significantly more plastic than intertidal zones, with extrapolation suggesting approximately 6.8 million particles (≥1 mm) across the beach surface.
RETRACTED: Microplastic pollution in intertidal sediments along the coastline of China
Note: This paper has been retracted. Prior to retraction, it reported measuring microplastics in intertidal sediments at 13 coastal sites in China, finding widespread contamination with fragments and fibers. The retraction status means the specific data should not be relied upon.
[Microplastic Pollution of the Beaches in Xiamen Bay, China].
Microplastics were found across beaches in Xiamen Bay, China, with fibers and fragments being most common and concentrations higher near urban and industrial areas. The findings add to growing evidence that microplastic contamination is widespread along China's heavily populated coastline.
A framework for systematic microplastic ecological risk assessment at a national scale
This study developed a framework for assessing the ecological risks of microplastic pollution across China by analyzing data from 128 studies and over 3,400 sites. The research found that microplastic contamination is widespread in Chinese soil, water, and sediments, with some areas reaching concerning levels. This kind of large-scale risk assessment is important for understanding how widespread microplastic pollution may affect ecosystems and, ultimately, human health through contaminated food and water.
