Research advances on impacts micro/nanoplastics and their carried pollutants on algae in aquatic ecosystems: A review
This review examines how micro- and nanoplastics harm algae, which are the foundation of aquatic food chains, by slowing growth, reducing photosynthesis, and damaging cells. The effects are worse when microplastics carry other pollutants on their surfaces, creating a combined toxic effect. Since algae support the entire aquatic food web, damage to these organisms can ripple upward through fish and shellfish to affect the safety of seafood consumed by humans.
Unraveling the impact of phytoplankton secretions on the behavior of metal-containing engineered nanoparticles in aquatic environment
This review examines how tiny algae (phytoplankton) release natural substances that change the way metal nanoparticles behave in water, affecting whether they dissolve, clump together, or get absorbed by organisms. While focused on engineered nanoparticles rather than microplastics, the same biological processes apply to how plastic particles interact with living things in aquatic environments. Understanding these interactions is important for predicting how pollutants, including microplastics, move through water ecosystems and potentially into the food chain.
Impact of microplastics on aquatic flora: Recent status, mechanisms of their toxicity and bioremediation strategies
This review examines how microplastics affect aquatic plants, from microscopic algae to larger vegetation, by physically blocking sunlight and pores and disrupting photosynthesis, reproduction, and nutrient uptake. Prolonged exposure triggers excessive production of harmful reactive oxygen species in plant cells, which can lead to cell death. The authors also highlight bioremediation approaches, including certain plants and microorganisms that can adsorb or break down microplastics by 25 to 80 percent in laboratory settings.
