Toxicological consequences of microplastics pollution on aquatic Li Ving organisms: a review
Summary
This review examines the toxicological consequences of microplastic pollution on aquatic organisms, summarizing effects on growth, reproduction, oxidative stress, and endocrine function across fish, invertebrate, and algae model species.
Plastics are used all around the world and so often that their pollution is becoming a concern. The global demand on microplastics has increased because plastics have light weight and low production cost. Microplastics affect the aquatic environment; aquatic organisms and subsequently through food web bioaccumulation human beings. This study review the scientific literature on the current trend of toxicological consequences of micro plastics, sources of micro plastics, their toxicity to different aquatic organisms. Microplastics cause toxicity to humans through accumulation which includes health implications of Microplastic pollution. The most common microplastics found in aquatic environments are Low Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polyprophylene (PP), Polyvinylchloride (PVC), and Polyehylenetetraacetate (PET.) The effects of Microplastics on aquatic fishes and invertebrates include blockage of the digestive system, weight loss, depletion of energy reserves, disruption of reproduction, change in the ratio and distribution of cholesterol, nutritional shortage, reduction in growth, decline in fertility, abnormal behavior, lesions and internal wounds. Through Bioaccumulation the health effects caused by Microplastics to human beings include oxidative stress, cell damage, inflammation, hepatic lipid disease, skin irritation, breathing issues, cancer risk, cardiovascular illness, reproductive issues, disruption in oxidative stress and immune responses, diabetes, obesity, endocrine disturbance, cancer, cardiovascular, reproductive and developmental problems. Researchers have identified biological remediation and use of bio-plastics as the major methods used for mitigating Microplastic pollution, however the use of bioremediation methods have proven effective and environmentally friendly.

A comprehensive review of the impact of microplastics on aquatic organisms: From ingestion to ecological consequences
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.
Toxicity and biomarkers of micro-plastic in aquatic environment: a review
This review synthesizes literature on the toxicity and biomarker responses of aquatic organisms to microplastics, covering uptake routes, bioavailability factors, and both lethal and sub-lethal effects. It highlights oxidative stress, endocrine disruption, and genotoxicity as consistent toxic mechanisms across diverse aquatic species.
Ecotoxicological effects of microplastics and adsorbed contaminants on aquatic organisms
This review summarizes ecotoxicological studies on microplastics and their adsorbed contaminants in microalgae, crustaceans, mollusks, and fish. Across all tested organisms, microplastics caused growth inhibition, reduced reproduction, and physiological stress — particularly when carrying additional chemical contaminants.
Ecotoxicological effects of microplastics on biota: a review
This review examines the ecological impact of microplastics on organisms across different levels of the food chain, from plankton to fish. Researchers found that microplastic exposure triggers a range of harmful effects including oxidative stress, immune disruption, reproductive problems, and altered feeding behavior. The evidence suggests that microplastics pose a widespread toxicological threat to wildlife, though more research is needed to understand the long-term population-level consequences.
The organism fate of inland freshwater system under micro-/nano-plastic pollution: A review of past decade.
This review synthesized a decade of research on how micro- and nano-plastics affect freshwater organisms including microalgae, macrophytes, zooplankton, benthic invertebrates, and fish, finding that impacts range from impaired photosynthesis and oxidative stress to reproductive disruption and behavioral changes across multiple biological levels.
