Occurrence and Presence of Ubiquitous Microplastics and Their Effects on Delta Ecosystems Around the World
AI summary Read the abstract
Researchers reviewed the occurrence and ecological effects of microplastics in river delta ecosystems worldwide, finding that deltas — as convergence zones for riverine plastic transport — accumulate disproportionately high microplastic loads that threaten the biodiversity and ecological services of these highly productive coastal environments.
The ubiquitous microplastics (MPs), having sizes smaller than 5 mm, have become abundant in aquatic environments, raising concerns about their environmental and health implications. This chapter begins by detailing the occurrence of MPs in delta regions,...

Occurrence and Ecotoxicological Effects of Microplastics on Aquatic and Terrestrial Ecosystems
AI summary Read the abstract
Researchers reviewed how microplastics — now present in the water we drink, the food we eat, and the air we breathe — accumulate in and harm both aquatic and land-based ecosystems, highlighting the broad reach of plastic pollution as a threat to wildlife and potentially to human health.
Occurrence, Distribution, and Removal of Microplastics from Aquatic Ecosystems
AI summary Read the abstract
Researchers investigated the occurrence, distribution, and removal strategies for microplastics in aquatic ecosystems, reviewing how their pervasive presence and resistance to conventional treatment create persistent risks for both environmental and human 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.
A Review of Microplastics in Aquatic Sediments: Occurrence, Fate, Transport, and Ecological Impact
AI summary Read the abstract
Researchers reviewed how microplastics accumulate in aquatic sediments — particularly the ocean floor — finding that sediments act as a long-term sink where plastics alter microbial communities and harm bottom-dwelling organisms, meaning the ecological damage of plastic pollution extends far beyond what is visible at the water surface.
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.
