Microplastic analysis in urban areas and their impact on quality of life
Summary
Researchers reviewed the growing threat of microplastic pollution to biodiversity and human health, focusing on freshwater systems as a key exposure pathway. The study emphasizes the need for standardized identification methods for microplastics in freshwater environments.
Plastic pollution is a major threat to both biodiversity and human health. Due to its high environmental persistence, concern has grown in recent years regarding the effects of microplastic pollution on ecosystems and its potential long-term impact on human well-being. Advancing research into the identification of microplastics in freshwater systems is a crucial step toward addressing this environmental challenge. However, a significant global issue remains: the lack of standardized methods for the qualitative and quantitative analysis of microplastics in environmental samples. This study focuses on the identification and quantification of microplastics in two tributaries of the Jiul River, located in western Romania. Sampling was conducted at two monitoring sites, with Fourier-transform infrared spectroscopy (FTIR) combined with infrared microscopy used to generate reliable, high-resolution data. The microplastics analysed (particles <5 mm) were classified by size and polymer type. Results showed microplastics present at only one of the two sites—specifically, at the confluence of the Maleia stream with the eastern Jiul River. Most particles measured between 25 and 50 μm and were primarily composed of PET, LDPE, and HDPE polymers. PET was the most frequently detected, highlighting the need for targeted.

Microplastic analysis in urban areas and their impact on quality of life
Researchers assessed microplastic contamination in urban water environments and evaluated its impact on community quality of life, arguing that a critical gap in standardized analytical methods is limiting progress in both research and environmental management of microplastic pollution.
Microplastics in freshwater ecosystems: what we know and what we need to know
This review examines the state of knowledge on microplastic contamination in freshwater ecosystems, which have received far less scientific attention than marine environments despite being major pathways for plastic transport. Researchers found that freshwater microplastic concentrations can be extremely high near urban areas and that organisms from insects to fish readily ingest these particles. The study identifies key research gaps including the need for standardized detection methods and better understanding of how microplastics move through and affect freshwater food webs.
Microplastics in freshwater systems: A review of the emerging threats, identification of knowledge gaps and prioritisation of research needs
This review synthesizes the growing body of research on microplastic contamination in freshwater rivers, lakes, and sediments, which has received far less attention than marine environments. Researchers found that freshwater microplastic concentrations can rival or exceed those reported in ocean studies, particularly near urban and industrial areas. The study identifies critical knowledge gaps including the lack of standardized sampling methods and limited understanding of how microplastics affect freshwater organisms and ecosystems.
Microplastic contamination, an emerging threat to the freshwater environment: a systematic review
Researchers systematically reviewed the spread of microplastics in freshwater ecosystems — rivers, lakes, and streams — documenting their sources, how they move through water, the damage they cause to aquatic organisms, and the methods used to detect them. Their review serves as a baseline reference for future research and calls for improved waste management to protect freshwater environments from ongoing microplastic contamination.
Microplastics in water: occurrence, detection, and impacts – a comprehensive review of multiple studies
This comprehensive review synthesized current knowledge on microplastic occurrence, detection methods, and impacts across marine, freshwater, and remote aquatic ecosystems. Researchers highlighted that microplastic concentrations are particularly high in urban rivers, transported through runoff, atmospheric deposition, and river input. The review identifies critical research gaps including the need for standardized detection methods and more studies on chronic human exposure through contaminated seafood and drinking water.
