Hitchhiking into the deep: how microplastic particles are exported through the biological carbon pump in the North Atlantic ocean

Understanding residence times of plastic in the ocean is a major knowledge gap in plastic pollution studies. Observations report a large mismatch between plastic load estimates from worldwide production and disposal and actual plastics floating at the sea surface. Surveys of the water column, from the surface to the deep sea, are rare. Most recent … More Hitchhiking into the deep: how microplastic particles are exported through the biological carbon pump in the North Atlantic ocean

Microplastics and Nanoplastics (chapter)

Microplastics have become a constant and ubiquitous component of the marine environment, being found in water surface, along water column, and in sediments, beaches, and organisms worldwide. Assessing microplastics in the environment is necessary to understand sources, distribution, abundance, and ecological consequences for marine ecosystems, especially considering that microplastic contamination is expected to increase in … More Microplastics and Nanoplastics (chapter)

Influence of particle size and fragmentation on large-scale microplastic transport in the mediterranean sea

Microplastic particles move three-dimensionally through the ocean, but modeling studies often do not consider size-dependent vertical transport processes. In addition, microplastic fragmentation in ocean environments remains poorly understood, despite fragments making up the majority of microplastic pollution in terms of the number of particles and despite its potential role in mass removal. Here, we first … More Influence of particle size and fragmentation on large-scale microplastic transport in the mediterranean sea

Global meta‐analysis reveals diverse effects of microplastics on freshwater and marine fishes

Microplastic debris is a globally ubiquitous pollutant with diverse consequences for fishes, ranging from severe negative impacts to neutral, or even, positive effects. In the present study, we conducted a systematic review and meta-analysis of experimental and observational studies to test for the impacts of microplastic exposure on freshwater, estuarine and marine fishes across diverse … More Global meta‐analysis reveals diverse effects of microplastics on freshwater and marine fishes

Microplastic leachates disrupt the chemotactic and chemokinetic behaviours of an ecosystem engineer (Mytilus edulis)

Highlights • Mussels are sensitive to their chemical environment. • No behavioural changes in mussels were detected in the presence of conspecific cues and injured conspecifics. • Mussels adapt their behaviour to the detection of predator cues by a reduction of their speed and gross distance. • Mussels’ behaviour is impaired by microplastic leachates through … More Microplastic leachates disrupt the chemotactic and chemokinetic behaviours of an ecosystem engineer (Mytilus edulis)

Microplastics alter multiple biological processes of marine benthic fauna

Highlights • Meta-analysis revealed microplastics weaken multiple processes fundamental to seabed life. • Surge in research helps establish that plastic impacts are stronger than thought. • Severity of impact depends on feeding strategy, life stage and taxonomic group. • Early life stages are most strongly impacted by microplastic exposure. • Leaking chemicals generate stronger responses … More Microplastics alter multiple biological processes of marine benthic fauna
