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.
Spatiotemporal variations of microplastics and influencing factor analysis in coastal seawater of Qingdao, China
Researchers surveyed microplastic pollution in the coastal waters of Qingdao, China, and found average concentrations of 293 to 412 particles per cubic meter, with higher levels in summer. The distribution pattern showed increasing concentrations from east to west, influenced by ocean currents, urban runoff, and tourism activity. The study provides a detailed picture of how human activity and environmental factors shape microplastic pollution patterns along a major coastal city.
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.
Spatial Patterns of Microplastics in Surface Seawater, Sediment, and Sand Along Qingdao Coastal Environment
This study examined microplastic distribution across seawater, sediment, and beach sand at 10 zones around Qingdao, China, finding concentration patterns strongly associated with the type of human activity at each site. Abandoned aquafarms and harbors showed the highest contamination, and chlorinated polyethylene fragments dominated all environmental compartments.

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.
Occurrence, Composition, and Relationships in Marine Plastic Debris on the First Long Beach Adjacent to the Land-Based Source, South China Sea
Researchers characterized the occurrence, composition, and relationships of marine plastic debris collected from a remote location during a first systematic survey. The study provides baseline data on plastic litter types and polymer composition in an understudied marine region.
A Survey of Marine Coastal Litters around Zhoushan Island, China and Their Impacts
Researchers surveyed marine litter around a Chinese island using stratified sampling across different beach types and found plastic dominating the debris. Local fishermen and tourists expressed willingness to reduce littering with appropriate incentives, highlighting the role of public engagement in coastal plastic management.
[Distribution Characteristics of Microplastics in Surface Water and Sediments of Haizhou Bay, Lianyungang].
Researchers characterized microplastic pollution in surface water and sediments of Haizhou Bay, a small-to-medium-sized inshore bay in Lianyungang, China, documenting the main polymer types, abundances, and spatial distribution patterns to fill a gap in knowledge about microplastics in smaller Chinese coastal environments.
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.
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.
Changes in Sources and Composition of Beach Waste in Coastal Cities around the Bohai Sea of China during the Tourist Peak and Off-Peak Seasons
