A comprehensive review on the adverse effect of microplastics in the gastrointestinal system of Artemia sp.
AI summary Read the abstract
This comprehensive review examines the adverse effects of microplastic ingestion on the gastrointestinal system of Artemia, a small crustacean widely used as a model organism. Researchers summarized evidence that microplastics like polyethylene and polystyrene can disrupt gut microbial diversity, impair development, and affect overall organism health. The study highlights Artemia as a valuable indicator species for understanding how microplastics move through aquatic food chains.
Microplastic waste in aquatic environments can lead to the mortality of large marine creatures, as it increases the risk of entanglement, strangulation, and starvation. Even though micro- and nano-plastics pose a hidden threat, researchers still know little about them. The food source is an essential factor in gut microbial diversity. A well-balanced intestinal microbiome impacts animal development and health. According to research, microplastics (MPs) like polyethylene (PE) and polystyrene (PS) affected the gut microbiota of Artemia sp., increasing their genetic diversity. Therefore, the present study examined the negative impacts of MPs within the gastrointestinal tract of sp., the primary protein source of fish. A comprehensive literature review showed that microplastic contamination and its additives impair environmental and aquatic health. The findings of this research show that MPs alter the gut microbiota of Artemia, which in turn affects fish and, ultimately, human health via a cascade of impacts.

Toxicity evaluation of polypropylene microplastic on marine microcrustacean Artemia salina: An analysis of implications and vulnerability
AI summary Read the abstract
Researchers prepared polypropylene microplastics and tested their toxic effects on the marine crustacean Artemia salina at different life stages. They found that the particles accumulated in the organisms' digestive tracts and caused significant mortality, particularly in the earliest developmental stages. The study demonstrates that polypropylene microplastics pose a real threat to small marine organisms that form the base of ocean food webs.
Artemia genus as a tool for studies of microplastic ingestion and trophic transfer—a review
AI summary Read the abstract
This review paper summarizes research showing that tiny sea creatures called Artemia (brine shrimp) eat microscopic plastic particles and pass them up the food chain to other animals. Scientists use these shrimp as a simple way to study how microplastics move through ocean food webs and affect sea life, which matters because these plastics could eventually reach the seafood we eat. The research shows mixed results—sometimes the plastic particles harm the shrimp, and sometimes they don't, so more studies are needed to understand the real risks.
The uptake and elimination of polystyrene microplastics by the brine shrimp, Artemia parthenogenetica, and its impact on its feeding behavior and intestinal histology
AI summary Read the abstract
Researchers studied the uptake, elimination, and intestinal effects of polystyrene microplastics on brine shrimp larvae. They found that the larvae ingested microplastics at rates dependent on concentration, exposure time, and food availability, and that the particles caused intestinal damage. The study demonstrates that microplastic contamination can harm the health and feeding behavior of zooplankton larvae, which are critical components of marine food webs.
A comprehensive review of the impact of microplastics on aquatic organisms: From ingestion to ecological consequences
AI summary Read the abstract
This comprehensive review assessed the impacts of microplastics on diverse aquatic organisms—including fish, marine mammals, mollusks, crustaceans, and microorganisms—from ingestion through ecological-level consequences. The authors found that microplastics cause physical injury, oxidative stress, endocrine disruption, and behavioral changes across taxa, with downstream effects on food web structure and ecosystem function.
Impacts of microplastics on gut health: Current status and future directions
AI summary Read the abstract
This systematic review found consistent evidence across mouse, fish, and earthworm models that microplastics disrupt gut microbiota composition, impair intestinal barrier integrity, and trigger gastrointestinal inflammation. The correlation between microplastic exposure and gut health deterioration was statistically significant across all animal models examined.
