ClearA systematic review and scientometrics analysis on microplastic pollution on coastal beaches around the globe
This systematic review analyzes microplastic pollution on coastal beaches worldwide. The research found that beach contamination varies widely by region but is present on virtually every coastline studied. This matters because beaches are not just recreational areas but also habitats where microplastics can enter marine food webs and eventually reach people through seafood consumption.
Estimating global marine surface microplastic abundance: systematic literature review
Researchers conducted a systematic literature review to estimate global marine surface microplastic abundance, compiling data from studies worldwide to produce abundance maps. The study found significant variation in microplastic concentrations across different ocean regions, providing a broader picture of the scale and distribution of marine microplastic pollution.
A review of plastic debris in the South American Atlantic Ocean coast – Distribution, characteristics, policies and legal aspects
Researchers compiled and reviewed studies on plastic debris along the entire South American Atlantic coast, covering distribution patterns, types of plastic, and existing policies. They found that macroplastic items like packaging and cigarette butts dominate beach litter, while microplastic contamination is widespread in water and sediment across the region. The review highlights significant gaps in research coverage and inconsistencies in national regulations that hinder effective plastic pollution management.

Researchers found microplastic pollution along 91 km of coastline in southern Sri Lanka, with 60% of beach sand sites and 70% of surface water sites testing positive, characterizing the polymers, shapes, and colors present across the sampled coastal environments.
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.
Microplastic pollution across the Brazilian coastline: Evidence from the MICROMar project, the largest coastal survey in the Global South
As part of Brazil's MICROMar project, researchers analysed 4,134 samples from 1,024 beaches along approximately 7,500 km of Brazilian coastline to produce the largest standardised coastal microplastic survey in the Global South. Microplastics were found ubiquitously, with concentration patterns linked to population density, coastal morphology, and river inputs.
Research priorities on microplastics in marine and coastal environments: An Australian perspective to advance global action
Researchers conducted a systematic review of microplastic research across Australian coastal environments and gathered expert stakeholder input to identify priority research directions. They found significant gaps in understanding microplastic sources, transport pathways, and biological impacts specific to Australian marine ecosystems. The study provides a framework of research priorities aimed at informing evidence-based policy and management strategies for microplastic pollution.
Research landscape of a global environmental challenge: Microplastics
This bibliometric analysis mapped global microplastic research output, finding a sharp increase in publications since 2006 and identifying China, the USA, and Germany as the most prolific contributors. The study distinguishes between primary microplastics (industrially produced) and secondary microplastics (formed by fragmentation) and contextualizes their global distribution.
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.
Microplastics in coastal and oceanic surface waters and their role as carriers of pollutants of emerging concern in marine organisms
Researchers analyzed 167 studies on microplastics in ocean surface waters and marine organisms, finding that fragments and fibers are the most common particle types across all regions studied. The review highlights that microplastics act as carriers for other harmful pollutants, increasing the chemical burden on marine life. The uneven global distribution of research means that microplastic contamination in many ocean regions remains poorly understood.
Analysis of the Current Situation of Marine Garbage and Microplastic Pollution in Typical Coastal Areas of Qingdao
Researchers investigated coastal marine debris and microplastic pollution at two beaches in Qingdao, China, examining the types, sources, components, and spatiotemporal distribution through field surveys, sample analysis, and component identification. The study proposed management responses including strengthened public education, stricter monitoring measures, and promotion of technological innovation and international cooperation.
