Abundance of Microplastics in Marine and Freshwater Ecosystem and it’s Impact on Biotic and Abiotic Components
AI summary Read the abstract
This review synthesizes current knowledge on microplastic abundance across marine and freshwater environments, covering detection methods, distribution patterns, and impacts on organisms — underscoring that microplastics act not only as physical hazards but also as vectors for transporting additional chemical pollutants through ecosystems.
The article focuses on the abundance of microplastics (MPs) in various environmental matrices, such as sediment and water, and their potential impacts. MPs can be considered as plastic particles that are less than 5 mm in dimension. The article presents an overview of the methods used for detecting and quantifying MPs in environmental samples, including spectroscopic techniques, microscopy, and chemical digestion. It also summarizes the current understanding of the distribution and abundance of MPs in various environmental compartments highlighting their importance in different environmental compartments. This article further discusses the potential impacts of MPs on different biota, such as marine organisms and terrestrial animals, and their ability to act as carriers for pollutants and other harmful substances. The review emphasizes the need for further research to better understand the impacts of MPs and to develop effective management strategies to mitigate their environmental effects.

Microplastics in the Marine Ecosystems: Identification and Impacts
AI summary Read the abstract
Tiny plastic particles called microplastics, broken-down bits of everyday plastic waste, are showing up along India's coastlines, and this review paper rounds up what scientists have found so far. While research on their health effects is still catching up, these particles are known to persist in the environment and can enter the food chain through seafood, raising concerns about long-term exposure for coastal communities. The authors point out that India still needs a lot more research to fully understand how serious this problem is and what it means for people's health.
Microplastic Pollution in Aquatic Ecosystems: A Comparative Review of Sources, Impacts, and Management in Marine and Freshwater Habitats
AI summary Read the abstract
This comparative review synthesized research on microplastic sources, distribution, and impacts across marine and freshwater environments, highlighting microbeads and polymer fragmentation as primary contamination drivers. Establishing a unified understanding of microplastic behavior across aquatic habitats is essential for designing monitoring frameworks that track human exposure through drinking water and seafood.
Emergence of Microplastics in the Aquatic Ecosystems: Sources and Their Characteristics
AI summary Read the abstract
Researchers reviewed the sources, physical and chemical characteristics, and environmental distribution of microplastics in aquatic ecosystems, covering both primary particles from industrial and personal care products and secondary particles generated through fragmentation of larger plastics. Understanding the diversity of particle sources and properties is foundational for modeling exposure pathways and predicting which ecosystems and human populations face the greatest contamination risk.
Status of Microplastic Pollution in the Freshwater Ecosystems
AI summary Read the abstract
Researchers reviewed the status of microplastic pollution in freshwater ecosystems, noting that only 7% of all plastic produced globally is recycled, leaving vast quantities to accumulate in rivers and lakes. These microplastic particles pose significant risks to aquatic life and potentially to people who depend on freshwater sources for drinking and food.
Examining the Environmental Concerns Caused by the Microplastic Contamination in Marine Ecosystem
AI summary Read the abstract
This review examines the environmental concerns posed by microplastic contamination in marine ecosystems, surveying sources, distribution patterns, biological impacts on marine organisms, and pathways of entry into food chains. As marine microplastics accumulate in fish, shellfish, and other seafood, they represent a direct and growing dietary exposure route for humans consuming ocean-derived food products.
