Exploring the Sources, Fate, and Processing of Microplastics in Seasonally Stratified Lakes
AI summary Read the abstract
This report investigates the sources, transport, and fate of microplastics in seasonally stratified lakes in New York State, funded by the U.S. Geological Survey. It contributes to understanding how microplastics behave in freshwater lake systems.
This report was prepared for the New York State Water Resources Institute (NYSWRI) with support from the U.S. Geological Survey under Grant/ Cooperative Agreement No. G16AP00073

AI summary Read the abstract
This New York State report quantified microplastic pollution in Onondaga and Skaneateles Lakes in central New York, providing baseline concentration and distribution data for two contrasting lake types. The findings support state-level monitoring and management efforts for emerging plastic contaminants in freshwater ecosystems.
It’s Complicated: Spatial and Temporal Variation in Microplastic Pollution in Seneca Lake, Finger Lakes, New York, Usa
AI summary Read the abstract
Researchers conducted seven sampling cruises across Seneca Lake in 2022 to assess spatial and temporal variability of microplastic contamination in a major drinking water source, finding that concentrations fluctuate daily with wind patterns, lake currents, and limnological conditions. The study found that focusing solely on wastewater treatment is insufficient, as precipitation, streams, and atmospheric deposition also contribute significantly to lake contamination.
Laboratory and numerical investigation of the factors controlling the residence time of microplastics in the water column of thermally stratified lakes
AI summary Read the abstract
Researchers used laboratory experiments and numerical modeling to investigate how thermal stratification in lakes affects the residence time of microplastics in the water column, finding that stratification traps particles in specific depth layers. Thermally stratified summer conditions increase the likelihood that microplastics will be encountered and ingested by filter-feeding organisms at particular depths.
Tracing the journey of microplastics in lake from surface water to accumulation in the sediments
AI summary Read the abstract
Researchers conducted a comprehensive seasonal monitoring study of microplastics in an urban lake in Latvia, tracking distribution in surface water, measuring sediment deposition rates over one year, and analyzing dated sediment archives to determine which environmental compartment best represents long-term microplastic pollution trends. The study aimed to identify the most suitable monitoring matrix and establish standardized sampling protocols for freshwater microplastic research.
Understanding the path of microplastics in lake from surface water to sediments
AI summary Read the abstract
Researchers conducted a comprehensive study of microplastics in a small urban lake in Latvia, tracking seasonal dynamics in surface water, historical deposition in dated sediment cores, and accumulation rates over one year. The study found increasing microplastic concentrations over time and seasonal variation linked to rainfall and temperature, providing a detailed picture of how microplastics move through a freshwater system.
