Microplastics in Portuguese Effluents: Extraction and Characterization
AI summary Read the abstract
Researchers extracted and characterized microplastics from wastewater effluents in Portugal, finding that even treated water released into the environment still carries significant plastic contamination. The results underscore the limitations of current water treatment systems in capturing microplastics before they enter rivers and coastal waters.
Microplastics (MPs) awareness has been growing particularly after several alarming reports about “garbage patches” in the world. Plastics do not biodegrade in any meaningful way and, up to now, only a small percentage of plastic waste is recycled, being...

AI summary Read the abstract
Researchers reviewed the occurrence and detection of microplastics across water and wastewater systems, summarizing contamination levels in different water sources and treatment stages while identifying gaps in sampling and analytical methods that limit understanding of how microplastics cycle through aquatic environments.
Microplastics in Wastewater
AI summary Read the abstract
Researchers reviewed the sources, fate, and treatment of microplastics in wastewater systems, finding that conventional treatment plants remove a significant portion of microplastics but still discharge millions of particles daily through effluents and biosolids, with remaining particles posing ongoing environmental and health risks.
Microplastics in Wastewater
AI summary Read the abstract
Researchers reviewed how microplastics enter wastewater systems through multiple human activity pathways and how conventional treatment plants, while removing a large fraction, still discharge significant quantities of microplastic particles into receiving water bodies, threatening aquatic ecosystems and downstream drinking water quality.
Microplastics in River Sediments Nearby to a Sewage Treatment Plant: Extraction, Processing and Characterization Assessment
AI summary Read the abstract
Researchers developed and assessed methods for extracting, processing, and characterizing microplastics from river sediments near a sewage treatment plant, documenting pollution levels and particle characteristics. Rivers act as both sinks and transport corridors for microplastics from wastewater discharge, making robust sediment sampling methods essential for tracking pollution sources and protecting downstream aquatic food webs.
