Spatial distribution and risk assessment of microplastics in surface sediments in semi-enclosed waters: a case study of Laizhou Bay
Researchers conducted a comprehensive spatial analysis and risk assessment of microplastic contamination in surface sediments of Laizhou Bay, a semi-enclosed coastal water body in China. They characterized the distribution and composition of microplastics to assess threats to marine organisms and ecosystem health in this type of vulnerable coastal environment.
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.
[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.
Microplastic Distribution and Influence Factor Analysis of Seawater and Surface Sediments in a Typical Bay With Diverse Functional Areas: A Case Study in Xincun Lagoon, China
Researchers assessed microplastic distribution in Xincun Lagoon in China, finding that different human activities such as tourism, fishing, and aquaculture directly influenced the type and level of microplastic pollution in seawater and sediments.
Spatial Distribution, Key Influencing Factors, and Ecological Risk of Microplastics in Pearl River Estuary Water and Sediments
Researchers mapped the distribution of microplastics in the water and sediments of the Pearl River Estuary in China and identified the key factors driving contamination levels. Fibers were the most common microplastic type found, and human activity along the coast strongly influenced pollution patterns. The study also assessed ecological risks and provides a framework for understanding how microplastics accumulate in heavily populated estuarine environments.
Spatial distribution, morphology, and risk assessment of microplastics in sediment from the Pearl River Estuary, China
Researchers assessed microplastic contamination in sediment from the Pearl River Estuary in China, one of the world's most densely populated coastal regions. They found microplastics widely distributed across the estuary, with varying shapes and polymer types linked to both urban and industrial sources. The study provides a risk assessment suggesting that sediment microplastic pollution in this ecosystem warrants ongoing monitoring and management.
Distribution characteristics of microplastics in the seawater and sediment: A case study in Jiaozhou Bay, China
Researchers surveyed microplastic pollution in the seawater and sediments of Jiaozhou Bay, a semi-enclosed bay in China heavily impacted by human activity. They found microplastic concentrations of 20 to 120 items per cubic meter in seawater and 7 to 25 items per kilogram in sediment, with fibers being the dominant shape and PET the most common polymer.
