ClearExploring the impact of polystyrene microplastics on human health: unravelling the health implications of polystyrene microplastics (PS-MPs): a comprehensive study on cytotoxicity, reproductive health, human exposure, and exposure assessment
This study explores the various ways polystyrene microplastics can affect human health, including through impacts on cells, reproductive tissues, and cumulative exposure from food and consumer products. Researchers found evidence that toxic chemicals leaching from polystyrene can enter the body through multiple routes and accumulate over time. The findings emphasize the importance of standardized methods for monitoring human microplastic exposure.
Nanoplastics in the oceans: Theory, experimental evidence and real world

Microplastics: challenges of assessment in biological samples and their implication for in vitro and in vivo effects
This review examines the challenges of detecting and assessing microplastics in biological samples, noting that analytical limitations and lack of standardized methods hinder our understanding of health effects. The study highlights that humans are exposed to microplastics primarily through ingestion and inhalation, and that more long-term studies with standardized protocols are needed to understand the full scope of potential biological impacts.
Review of the toxic effects and mechanisms of polystyrene micro/nanoplastics across multiple animal species
This review comprehensively examines the toxic effects of polystyrene micro- and nanoplastics across marine animals, freshwater species, soil organisms, and mammals.

Review of ecotoxicological studies of widely used polystyrene nanoparticles
Researchers reviewed ecotoxicological studies on manufactured polystyrene nanoparticles and their effects on aquatic organisms. They found that many studies used insufficiently characterized particles and short-term exposure conditions that may not reflect real environmental scenarios. The review recommends improved particle characterization, proper purification before testing, and longer-term exposure studies to generate more environmentally relevant toxicity data.
The detrimental impact of microplastics on the Marine Environment and potential remediation strategies.
This review analyzes the detrimental impacts of microplastics on marine environments, summarizing documented hazards to marine life and ecosystems from historical and recent research, and evaluates several representative remediation strategies for addressing microplastic contamination. The authors found that microplastics interfere broadly with marine organism physiology and food web dynamics, and that current treatment approaches — including filtration, photocatalysis, and biological degradation — each carry limitations requiring further development for large-scale application.
Methods Matter: Methods for Sampling Microplastic and Other Anthropogenic Particles and Their Implications for Monitoring and Ecological Risk Assessment
This methods review examines how different sampling approaches for microplastics — including mesh size, sample volume, and processing techniques — affect quantification results, arguing that methodological inconsistency is a major barrier to ecological risk assessment.
Effects of polystyrene microplastics on early stages of two marine invertebrates with different feeding strategies
Researchers exposed early life stages of two marine invertebrates to polystyrene microplastics to measure effects on development and survival. The study found that even early life stages are vulnerable to microplastic exposure, raising concerns about impacts on marine invertebrate populations.
Micro- and nanoplastic toxicity: A review on size, type, source, and test-organism implications
This comprehensive review analyzed 615 studies on the toxicity of micro- and nanoplastics across different polymer types, sizes, and organisms. A major finding is that over 90% of nanoplastic research uses only polystyrene, leaving huge gaps in our understanding of other common plastics at the nanoscale. The review highlights that smaller particles are generally more toxic and that more research is urgently needed on the nanoplastics people are most likely to encounter in everyday life.
Studies of the effects of microplastics on aquatic organisms: What do we know and where should we focus our efforts in the future?
This review critically evaluates published research on microplastic effects on aquatic organisms and identifies significant gaps between laboratory experiments and real-world conditions. Researchers found that most studies use polystyrene spheres at concentrations far higher than those found in the environment, while the most common microplastics in nature are fragments and fibers of other polymer types. The study calls for more environmentally realistic experimental designs to better understand the actual ecological risks of microplastic pollution.
Ecotoxicological effects of microplastics in the marine environment
This review synthesizes ecotoxicological evidence on the impacts of microplastics in the marine environment, drawing on over 50 scientific articles to assess effects at molecular, cellular, organ, individual, and population levels. The authors identify critical methodological limitations including non-standardized particle characteristics, limited species diversity in testing, and scarce community-level studies, concluding that current risk assessment frameworks are insufficient for the more than 5,300 grades of plastics entering marine ecosystems.
