Research highlights: impacts of microplastics on plankton
Summary
This research highlights piece summarizes emerging evidence for the impacts of microplastics on marine plankton — the base of ocean food webs — including effects on feeding, reproduction, and population dynamics. The findings underscore that microplastic pollution has the potential to disrupt marine ecosystems from the bottom up.
Each year, millions of metric tons of the plastic produced for food packaging, personal care products, fishing gear, and other human activities end up in lakes, rivers, and the ocean. The breakdown of these primary plastics in the environment results in microplastics, small fragments of plastic typically less than 1-5 mm in size. These synthetic particles have been detected in all of the world's oceans and also in many freshwater systems, accumulating in sediment, on shorelines, suspended in surface waters, and being ingested by plankton, fish, birds, and marine mammals. While the occurrence of plastics in surface waters has been surveyed in a number of studies, the impacts of microplastics on marine organisms are still being elucidated. This highlight features three recent publications that explore the interactions of microplastics with planktonic organisms to clarify the effects of these pollutants on some of the ocean's smallest and most important inhabitants.

The Impacts of Microplastics on Zooplankton
This review examines the growing concern about microplastic impacts on marine and freshwater zooplankton, noting that these tiny organisms can ingest microplastics and are at the base of most aquatic food webs. Plastic ingestion can cause gut blockages, immune responses, energy loss, and reduced reproduction, with potential cascading effects on ecosystems and the species—including fish and humans—that feed on zooplankton.
Impacts of Microplastics on Zooplankton
This review examines the impacts of microplastics on zooplankton communities, covering how microplastic ingestion and physicochemical alterations of aquatic environments affect zooplankton feeding, reproduction, and community structure. Zooplankton are highlighted as ecologically critical organisms whose disruption can cascade through aquatic food webs.
Ecological impact of microplastic pollution on marine food webs
This review examines how microplastic pollution disrupts marine food webs, tracing the transfer of plastic particles and associated chemicals from plankton through fish to top predators and analyzing the ecological consequences for marine biodiversity and ecosystem functioning.
Feasting on microplastics: ingestion by and effects on marine organisms
This review synthesizes experimental studies on microplastic ingestion and effects across a wide range of marine organisms, finding evidence of physical harm, reproductive effects, and reduced feeding in multiple taxa. The paper provides a comprehensive overview of the biological consequences of microplastic ingestion and identifies key knowledge gaps for future research.
Microplastic pollution in the marine environment: Sources, impacts, and degradation.
This review summarizes existing research on microplastic pollution in the ocean, covering sources, effects on marine life, and degradation. Microplastics harm marine organisms across the food chain, from plankton to fish, affecting their growth, reproduction, immune systems, and behavior. Since humans consume many of these marine species, the widespread contamination raises concerns about microplastic exposure through seafood.
