From Ocean to Medicine: Harnessing Seaweed’s Potential for Drug Development
This review explores how compounds derived from seaweed show promise for drug development, with properties including antioxidant, anti-inflammatory, and anticancer activity. While not directly about microplastics, marine-derived bioactive compounds could be relevant to addressing the inflammation and oxidative stress that microplastic exposure is known to cause in the body.
Screening of the Toxicity of Polystyrene Nano- and Microplastics Alone and in Combination with Benzo(a)pyrene in Brine Shrimp Larvae and Zebrafish Embryos
Researchers found that polystyrene nano- and microplastics alone showed minimal acute toxicity to brine shrimp and zebrafish embryos, but when combined with benzo(a)pyrene, the plastics altered the pollutant's bioavailability and toxic effects.
Potential toxicity of Schisandra chinensis to water environment: acute toxicity tests with water crustaceans
Aquatic toxicity tests with water crustaceans and algae assessed the environmental safety of Schisandra chinensis extracts used in health supplements, finding that bioactive secondary metabolites in this plant can cause ecotoxicological effects in aquatic organisms.
Determination of microplastics toxicity
Lab experiments tested the toxicity of polyethylene, polypropylene, and polystyrene microplastics on a green alga, a water flea, and zebrafish embryos, finding harmful effects at various concentrations. The study provides toxicological data supporting that microplastics pose real risks to aquatic organisms.
Acute and chronic effects of polystyrene microplastics on brine shrimp: First evidence highlighting the molecular mechanism through transcriptome analysis
Researchers investigated both acute and chronic toxicity of polystyrene microplastics on brine shrimp, using transcriptome analysis to uncover molecular mechanisms. While acute exposure did not significantly affect survival, chronic exposure led to concentration-dependent bioaccumulation and increased reactive oxygen species generation, with gene expression analysis revealing disrupted metabolic and stress response pathways.
Rehashing Our Insight of Seaweeds as a Potential Source of Foods, Nutraceuticals, and Pharmaceuticals
This review summarizes research on seaweed as a source of beneficial compounds including antioxidants, anti-inflammatory agents, and other health-promoting substances. While not directly about microplastics, the research is relevant because seaweeds grow in marine environments increasingly contaminated with microplastics. Understanding the health benefits of seaweed also requires considering the potential risks of microplastic contamination in these marine food sources.
Microplastic toxicity in shrimp: From mechanistic pathways to ecological implications.
Researchers systematically reviewed 94 studies on microplastic toxicity in shrimp, mapping mechanistic pathways from particle characteristics to oxidative stress, immune dysfunction, neurotoxicity, and reproductive impairment across hepatopancreas, gills, gut, and gonad tissues, and identifying shrimp as effective bioindicators for aquatic microplastic risk assessment.
PLA Nanoplastics Accumulate but Do Not Cause Acute Toxicity to Marine Rotifers, Brine Shrimps, and Zebrafish Embryos
Researchers tested the acute toxicity and bioaccumulation of polylactic acid nanoplastics in three aquatic model organisms—marine rotifers, brine shrimps, and zebrafish embryos—finding that PLA nanoparticles accumulated but did not cause acute toxicity at the tested concentrations.
[Effects of polystyrene microplastics (PS-MPs) on the growth, physiology, and biochemical characteristics of Hydrilla verticillata].
Researchers exposed an aquatic plant to increasing concentrations of polystyrene microplastics and found that high doses stunted plant height, reduced chlorophyll, and impaired photosynthesis. Submerged aquatic plants form the base of freshwater food webs, and their disruption by microplastic pollution could cascade through aquatic ecosystems.
Acute and subacute repeated oral toxicity study of fragmented microplastics in Sprague-Dawley rats
Researchers conducted acute and subacute oral toxicity studies of weathered polypropylene microplastics in rats, using realistic fragmented particles to assess health effects from dietary microplastic exposure, providing toxicological data relevant to human food safety.
Marine ecotoxicity of polystyrene microplastics, imidacloprid, and acyclovir: individual exposure in microalgae, rotifers and crustaceans
Researchers tested the individual toxicity of polystyrene microplastics, the pesticide imidacloprid, and the antiviral drug acyclovir on marine microalgae, rotifers, and crustaceans. All three pollutants caused dose-dependent toxicity, with crustaceans being most sensitive to polystyrene MPs and rotifers most affected by pharmaceutical exposure.
Saving the pharmacy of the sea: How does global change affect species with bioactive potential in the Mediterranean?
This study examined how human activities — including pollution, fishing, and climate change — threaten Mediterranean marine species that produce potentially useful bioactive compounds. Microplastic contamination is among the stressors affecting these species and their ability to produce molecules of pharmaceutical interest.
Biological toxicity of sulfamethoxazole in aquatic ecosystem on adult zebrafish (Danio rerio)
Not relevant to microplastics — this study examines how the antibiotic sulfamethoxazole affects zebrafish health, finding that chronic exposure causes liver and gill oxidative damage and disrupts gut bacteria, with no focus on plastic pollution.
Ecological Risks of Microplastic Toxicity on Biota and Plants
This review examines the ecological risks of microplastic toxicity to a wide range of organisms including plants, invertebrates, fish, and soil biota, synthesizing dose-response data and identifying the most sensitive species and exposure pathways across terrestrial and aquatic ecosystems.
A review of microplastic impacts on seagrasses, epiphytes, and associated sediment communities
This review synthesizes research on microplastic accumulation in seagrass ecosystems, examining effects on seagrass plants, epiphytic communities, and associated sediment biota. The authors identify seagrass meadows as both sinks for microplastics and potentially sensitive ecosystems where plastic contamination may disrupt complex ecological relationships.
Early evidence of the impacts of microplastic and nanoplastic pollution on the growth and physiology of the seagrass Cymodocea nodosa
Researchers explored the effects of polystyrene micro- and nanoplastics on the seagrass Cymodocea nodosa, which provides important ecosystem services in marine environments. The study found evidence of impacts on seagrass growth and physiology from plastic particle exposure. The findings are significant because seagrass meadows are particularly prone to accumulating plastic debris and are already declining globally due to other anthropogenic stressors.

Ekotoksičnost nesteroidnih protuupalnih lijekova na vodene organizme
This Croatian review examines the ecotoxicological effects of non-steroidal anti-inflammatory drugs (NSAIDs) on aquatic organisms. NSAIDs are widely detected in wastewater and surface waters, where they can harm fish, invertebrates, and algae even at low concentrations. Since microplastics can absorb and concentrate NSAIDs, their joint presence in water may amplify toxic effects on aquatic life.
