Estimation of the microplastics concentrations in the water column and bottom sediments of Ladoga Lake

Lake-wide assessment of microplastics in the surface waters of Lake Baikal, Siberia

AI summary · Read the abstract

Researchers conducted the first lake-wide survey of microplastics in Lake Baikal — one of the world's largest and most pristine freshwater bodies — finding concentrations 100 to 1,000 times higher than previous estimates, largely because earlier methods missed the smallest particles.

Occurrence and Effects of Microplastics in Lake Ecosystems: Particular Focus on Migration in Water and Food Chains

AI summary · Read the abstract

This review synthesizes findings on microplastic occurrence, sources, and ecological effects in lake ecosystems worldwide, with a focus on how microplastics migrate through water columns and accumulate across aquatic food chains. Lakes are critical freshwater resources for drinking water and fisheries, making the documented bioaccumulation and toxicity of microplastics in lake food webs a direct public health concern.

Vertical Distribution of Microplastics in the Water Column of Lake Ladoga

Mapping Microplastics in Zarivar Lake's Water Column, Western Iran: A Study on Abundance, Composition, and Ecological Risk Assessment

AI summary · Read the abstract

Spatial mapping of Zarivar Lake in western Iran using stereomicroscopy, SEM, and FTIR identified a mean microplastic concentration of 35.8 particles/L throughout the water column, with polystyrene, polypropylene, polyamide, PET, and polyurethane all detected. As a large freshwater lake supporting unique local biodiversity, Zarivar's contamination highlights the global reach of microplastic pollution into inland water bodies far from industrial centers.
