Case Study—Risks Posed by MPs Presence and Transport in Brisbane River Sediments, Australia
AI summary Read the abstract
This case study characterized the environmental risk and transport behavior of microplastics in urban river sediments collected from 22 sites along the Brisbane River in Australia, analyzing how sediment dynamics move plastic particles through the watershed. Urban river sediments act as both sinks and secondary sources of microplastic contamination, threatening downstream aquatic life and water quality used for human consumption.
This chapter presents the outcomes of a case study which focused on understanding the environmental risksEnvironmental risk and transportTransport processes of microplastics (MPs) in urban river sedimentsSediments. Sediment samples obtained from twenty-two sampling...

Use of Microalgae for the Removal of MPs as an Emerging Contaminant from Wastewaters
AI summary Read the abstract
Researchers reviewed the use of microalgae to remove microplastics from wastewater, examining how these organisms can capture plastic particles smaller than 5 mm while offering a biologically based treatment strategy for emerging contaminants found even in the human body.
Fate and Transport of Emerging Pollutants in Aquatic Environment
AI summary Read the abstract
Researchers reviewed the behavior of several emerging pollutants — including microplastics, phthalates, and antibiotics — in aquatic environments, highlighting how these contaminants spread through water systems and interact with ecosystems in ways that are still not fully understood.
Detection, characteristics, and some influencing factors of MPs in rainfall
AI summary Read the abstract
This systematic review synthesized global evidence that microplastics are transported through the troposphere and deposited via rainfall even in remote regions, with PET, polypropylene, polyamide, and polyethylene as the dominant polymers found in rainwater, and meteorological factors controlling variability. The findings confirm that atmospheric transport and precipitation represent a major dispersal vector for microplastics, meaning contamination of soils, drinking water sources, and human food systems is partly driven by weather patterns.
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.
