Benchmarking the uptake and excretion dynamics of microplastics in the marine copepod Calanus finmarchicus
AI summary
This study characterized microplastic contamination in commercial beer products from multiple countries, detecting particles in the majority of tested products. Brewing water quality was identified as the primary contamination source, with particle concentrations in finished beer correlating with local water supply microplastic concentrations rather than brewing process variables.

Uptake and excretion of polystyrene microplastics in the marine copepod Calanus finmarchicus
AI summary Read the abstract
This Norwegian master's thesis studied the uptake and excretion of polystyrene microplastic particles in the marine copepod Calanus finmarchicus, a key species in North Atlantic food webs. The results help quantify how these abundant zooplankton encounter, ingest, and eliminate microplastics, informing models of plastic transfer through the marine food chain.
The Impact of Microplastics on Marine Copepods
AI summary Read the abstract
Marine copepods, a foundational link in ocean food webs, ingest microplastics alongside natural prey, causing reduced feeding, reproductive impairment, and energy depletion that can cascade up through fish, seabirds, and marine mammals. Because copepods transfer energy from phytoplankton to higher trophic levels, their contamination with microplastics poses systemic risks to entire marine food chains.
Microplastics Uptake and Egestion Dynamics in Pacific Oysters, Magallana Gigas (Thunberg, 1793), Under Controlled Conditions
AI summary Read the abstract
Researchers studied how Pacific oysters (Magallana gigas) ingest and egest microplastics under controlled conditions, finding that ingestion rates were rapid and dose-dependent while egestion was slower, resulting in temporary accumulation that increases the oysters' exposure to adsorbed pollutants and pathogens during the retention period.
Microplastics Residence Time in Marine Copepods: An Experimental Study
AI summary Read the abstract
Laboratory experiments measured how long microplastics remain in marine copepods after ingestion, finding that residence times vary by particle type and size, with some particles persisting longer than others and informing estimates of microplastic transfer through marine food webs.
