Transport model: microplastic in Lake Baikal
AI summary Read the abstract
Researchers used a three-dimensional computer model to simulate how microplastics move through Lake Baikal under different current and wind scenarios. The model showed that particles can spread widely across the lake depending on the season and entry point, helping predict where microplastics accumulate in this ecologically critical freshwater body.
With the help of a transport model, the issues of the distribution of neutrally floating particles simulating microplastic (MP) in Lake Baikal are studied. A three-dimensional model of the lake hydro-thermodynamics in the non-hydrostatic formulation is used to produce the fields of currents and the other necessary parameters for the transport model. To give generality to the conclusions, we use a set of parameters that are conditionally combined into hypothetical scenarios. In them, we design the "climatic" scenarios of external influences, in accordance to which the fields of currents and temperature in the hydrodynamic model are calculated. Depending of the goals of the study, we also formulate the specific tasks for giving the impurity sources in the transport model. The results of calculations are presented, in which some possible locations of an increased concentration of impurities in the lake were revealed.

Fate and Distribution of Floating Microplastics in a Shallow Urban Lake: Field Sampling and Lagrangian Particle Tracking
AI summary Read the abstract
Researchers tracked how tiny plastic particles move and spread in a shallow urban lake (Taihu Lake), combining real water samples with computer simulations that model how plastics coated in algae and bacteria ("biofilm") travel through water. This matters because these lakes often supply drinking water, and understanding where microplastics accumulate can help identify hotspots and improve cleanup or filtering efforts before the plastics reach our taps.

AI summary Read the abstract
Researchers used 3D hydrodynamic modeling to simulate microplastic transport, residence time, and sedimentation patterns in lakes and reservoirs. The models showed that bathymetry and inlet-outlet flow patterns strongly control where microplastics accumulate on lake beds.
Hydrodynamic driven microplastics in Dongting Lake, China: Quantification of the flux and transportation
AI summary Read the abstract
Researchers developed a framework combining field monitoring with numerical simulation to quantify microplastic transport in Dongting Lake, a large freshwater lake in China. They estimated that roughly 199 trillion microplastic items entered and 129 trillion exited the lake in 2021, and identified four key accumulation zones overlapping with nature reserves and agricultural areas. The study suggests that these accumulation patterns pose considerable risks to both ecological biodiversity and food security.
