ClearEffects of microplastics pollution on the abundance and composition of interstitial meiofauna
Researchers found that microplastic accumulation in beach sediments negatively affected the abundance and community composition of meiofauna at lower intertidal levels on urban Colombian beaches, with microplastics explaining 39% of community variation in the most heavily impacted zone.
The distribution and ecological effects of microplastics in an estuarine ecosystem
Researchers surveyed 22 intertidal sites and found that microplastic abundance, size, and diversity correlated with benthic microalgal communities and sediment biostabilization properties in an estuarine ecosystem.
Short-term microplastic effects on marine meiofauna abundance, diversity and community composition
Researchers examined short-term effects of microplastics on marine meiofauna, measuring changes in abundance, species diversity, and community composition after plastic addition, finding dose-dependent disruption to these ecologically important small invertebrates.
Abundance of microplastics in intertidal and subtidal regions: A) sediments and B) water.
This study presents abundance data for microplastics in both intertidal and subtidal regions, comparing concentrations in sediment and water across habitat zones.
Distribution characteristics and ecological risk assessment of microplastics in intertidal sediments near coastal water
Researchers analyzed microplastic contamination in intertidal sediments from coastal areas and assessed the ecological risks these particles pose. They found microplastics in all sampled locations, with fibers and fragments being the most common shapes, and polyethylene and polypropylene the dominant plastic types. The study's risk assessment indicates that microplastic pollution in these transitional zones between land and sea warrants greater environmental attention.
Abundance, composition, and distribution of microplastics in intertidal sediment and soft tissues of four species of Bivalvia from Southeast Brazilian urban beaches
Researchers found 100% microplastic contamination in intertidal sediments and four bivalve species from urbanized Brazilian beaches, identifying polypropylene, polyethylene, and PET polymers in organisms commonly consumed by humans.
Effects of microplastics on sessile invertebrates in the eastern coast of Thailand: An approach to coastal zone conservation
Researchers assessed microplastic contamination in three abundant intertidal invertebrate species along Thailand's eastern coast, including rock oysters, barnacles, and periwinkles. They found microplastic accumulation rates of 0.2 to 0.6 particles per gram across all species, with filter-feeding organisms showing higher accumulation. The study suggests that sessile intertidal organisms can serve as effective bioindicators for monitoring coastal microplastic pollution levels.
Microplastics in intertidal water of South Australia and the mussel Mytilus spp.; the contrasting effect of population on concentration
Researchers confirmed for the first time the presence of microplastics in South Australian intertidal waters and blue mussels, finding a contrasting relationship between human population density and microplastic concentration in this coastal ecosystem.
The relation of sediment texture to macro- and microplastic abundance in intertidal zone
Researchers analyzed the relationship between sediment grain size and microplastic accumulation in an intertidal zone, finding that finer-grained sediments tend to accumulate more plastic particles. Understanding this relationship helps identify which coastal areas are at greatest risk from microplastic contamination.
Microplastic load of benthic fauna in Jiaozhou Bay, China
This study quantified microplastic load in benthic fauna from Jiaozhou Bay in China, finding that multiple invertebrate species ingested microplastics with concentrations influenced by feeding mode, habitat depth, and proximity to human activity, helping clarify factors controlling microplastic distribution in marine benthos.
Impacts of microplastics on coastal biota and the potential for trophic transfer
This research investigated how microplastics affect coastal marine organisms and whether they transfer up the food chain, finding that beach invertebrates readily ingest microplastics and show behavioral changes, and that contaminated prey can transfer plastics to predators. The results raise concerns about cascading effects through marine food webs.
Intertidal Concentrations of Microplastics and Their Influence on Ammonium Cycling as Related to the Shellfish Industry
Researchers determined the concentration and spatial distribution of microplastics in intertidal sediments at shellfish aquaculture sites and investigated their influence on ammonium cycling, finding that elevated microplastic concentrations altered nitrogen processing by benthic microbial communities. The results suggest microplastics at aquaculture densities may disrupt sediment nutrient dynamics with potential implications for shellfish productivity.
Microplastics in invertebrates on soft shores in Hong Kong: Influence of habitat, taxa and feeding mode
Researchers surveyed microplastic occurrence in 38 invertebrate species across 18 mudflats and sandy beaches in Hong Kong, finding that feeding mode and habitat type were stronger predictors of microplastic ingestion than taxonomic group, with suspension feeders in mudflat environments showing the highest contamination. The study provides a broad baseline for microplastic uptake across coastal invertebrate communities.
Distribution and characteristics of microplastics in 16 benthic organisms in Haizhou Bay, China: Influence of habitat, feeding habits and trophic level
Researchers examined microplastic contamination in 16 species of bottom-dwelling marine organisms in Haizhou Bay, China, and found plastics in every species tested, averaging about 9 particles per individual. The type of habitat, feeding strategy, and position in the food chain all influenced how much microplastic each species accumulated. The study confirms that benthic organisms are reliable indicators of microplastic pollution and that contamination is at a moderately high level by international standards.
Microplastic pollution and its relationship with the bacterial community in coastal sediments near Guangdong Province, South China
This study systematically characterized microplastic pollution in coastal sediments near Guangdong Province, China, and found that microplastic abundance was linked to changes in the local bacterial community. Higher microplastic levels were associated with shifts in microbial diversity, suggesting plastic pollution can alter the microbial ecology of marine sediments.
Ecology of mesozooplankton in a subtropical coastal lagoon: composition, spatial distribution and interactions with microplastic pollution
Researchers studied mesozooplankton ecology in a subtropical coastal lagoon, examining community composition, spatial distribution, and interactions with microplastic pollution to understand how plastic contamination affects zooplankton dynamics in coastal environments.
Presence of microplastics in benthic and epibenthic organisms: Influence of habitat, feeding mode and trophic level
This study examined microplastic occurrence in benthic and epibenthic invertebrates from the Western English Channel, finding that habitat type, feeding mode, and trophic level all influenced microplastic ingestion rates. The results suggest that bottom-dwelling filter feeders and deposit feeders are among the most exposed organisms in seafloor food webs.
Micro- and mesoplastics in the northern Baltic Sea : their fate in the seafloor and effects on benthic fauna
This dissertation examined micro- and mesoplastics in the northern Baltic Sea seafloor and tested their effects on bottom-dwelling organisms. Microplastics accumulated in fine-grained seafloor sediments, and exposure experiments showed negative effects on benthic invertebrates at realistic concentrations. The findings contribute to understanding how plastic pollution is affecting benthic ecosystems in a major semi-enclosed sea with significant human fishing and tourism activity.
