Emerging micropollutants in aquatic ecosystems and nanotechnology-based removal alternatives: A review
This review examines emerging micropollutants in water systems, including microplastics, pharmaceuticals, pesticides, and heavy metals, and how nanotechnology-based approaches can help remove them. These contaminants threaten drinking water safety and aquatic ecosystems worldwide. The paper evaluates various nanomaterial-based filtration and degradation methods as promising solutions for cleaning up contaminated water.
Building the Bridge From Aquatic Nanotoxicology to Safety by Design Silver Nanoparticles
This review examined the nanotoxicology of silver nanoparticles in aquatic environments, synthesizing findings on their environmental behavior and biological effects to help bridge the gap between hazard assessment and safety-by-design approaches for engineered nanomaterials.
A critical review on the biological impact of natural organic matter on nanomaterials in the aquatic environment
This review examines how natural organic matter in aquatic environments forms an ecological corona on the surface of nanomaterials, influencing their behavior, toxicity, and environmental fate. Researchers found that eco-corona formation can either increase or decrease the hazards posed by nanomaterials to aquatic organisms, making it a critical factor for environmental risk assessment.
A holistic approach to assess the toxic behaviour of emerging nanomaterials in aquatic system
Not relevant to microplastics — this book chapter reviews how emerging nanomaterials behave at nano-bio-eco interfaces, discussing toxicity, fate, and exposure potential in aquatic systems without a specific focus on plastic particles.
Toxicity of nanoplastics to aquatic organisms: Genotoxicity, cytotoxicity, individual level and beyond individual level
This review examines the toxic effects of nanoplastics on aquatic organisms across multiple levels of the food chain, from bacteria and algae to fish. Researchers found that nanoplastics can cause cell damage, genetic harm, and reproductive problems, with toxicity influenced by particle size, concentration, and surface properties. The study also highlights how nanoplastic effects on individual organisms can cascade to disrupt broader ecosystem dynamics.
