This National Science Foundation Project Grant of $159,763 will fund research on the surface properties and transport of micro- and nanoplastics in unsaturated soil. The University of Tennessee will receive funding through the Geosciences program (CFDA 47.050) to better understand how micro- and nanoplastics weather and move through soils. Specifically, the researchers will characterize how four common plastics - polyethylene, polypropylene, polystyrene, and a biodegradable plastic - change at...
The National Science Foundation awarded a two-year, $174,000 Project Grant to Princeton University under the Geosciences program (CFDA 47.050). The grant will fund research examining the effect of environmental conditions on the degradation pathways and sorption potential of microplastics and nanoplastics as vectors for inorganic pollution. The Geosciences program supports basic research to strengthen understanding of Earth's integrated system through atmospheric, earth, and ocean sciences. This...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $478,560 to Cornell University for a collaborative research project with the University of Aberdeen (UK) to investigate the interactions between microplastics, soil, and microorganisms. The project aims to unravel the formation and impact of the "plastisphere" - a unique microbial habitat that develops on the surface of degrading microplastics in soil - and how it affects water...

Specifically, the award will fund work to: 1) understand the creation and properties of secondary micro- and nano-plastics during weathering; 2) determine the impact of weathering on surface and colloidal characteristics; and 3) identify mechanisms governing...
This National Science Foundation (NSF) Project Grant award, provided through the Geosciences program (CFDA 47.050), supports a research project on microplastic pollution in the Finger Lakes watershed of New York state. The $358,976 grant, awarded on November 1, 2024, will fund a 3-year collaborative research effort led by Hobart & William Smith Colleges to investigate the sources, sinks, transport, and environmental impacts of microplastics. The project will provide mentored research...
This $299,999 National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award to Iowa State University of Science and Technology will fund research to understand the trapping of microplastic particles in riverbeds. The project leverages synergistic pore-resolving direct numerical simulations and theoretical modeling to reveal the physical processes involved in microplastic trapping and develop predictive models for retention rates. The goal is to enable more accurate...
This $344,888 federal Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to understand the trapping of microplastic particles in riverbeds. The project will leverage high-fidelity numerical simulations and theoretical modeling to reveal the physical processes involved in this trapping and develop predictive models for microplastic retention rates. The research aims to enable more accurate assessment of microplastic pollution impacts...
This $231,803 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research study on microplastic sources, sinks, transport, and environmental impact across the Finger Lakes watershed in New York. The primary awardee, the Research Foundation of the City University of New York, will lead this 3-year project to investigate the presence and behavior of microplastics in the air, water, soil, and organisms of the Finger Lakes region....
The National Science Foundation awarded a $386,959 Project Grant to the University of Missouri System under the Engineering program (CFDA 47.041) for the period of October 1, 2022 through March 31, 2026. The grant funds research into microplastics fate and contaminant transport in storm runoff using an interdisciplinary approach integrating material science and environmental engineering. Specifically, the grantee will investigate the roles of intrinsic and extrinsic material properties on...
The National Science Foundation (NSF) Division of Ocean Sciences awarded a $346,823 Project Grant to the Regents of the University of Colorado (doing business as the University of Colorado) to conduct research under the NSF Geosciences program (CFDA 47.050). This research project aims to better understand how transformations to microplastics in coastal environments impact their regional-scale transport and fate. The study will use Lagrangian tracers and existing hydrodynamic modeling to quantify...
The National Science Foundation (NSF) awarded a $258,210 grant under the Geosciences program to the University of Memphis to conduct research on the impacts of microplastic pollution on soil hydrology. The 5-year project, which began on March 1, 2024, aims to improve understanding of how microplastics can alter soil-water-plant interactions, soil pore structure, and desiccation crack development. The research will examine the effects of various microplastic characteristics, including size, shape, and degradation, on loamy soils with different organic matter content and hydrophobicity. The project will integrate research, education, and outreach activities, including professional development for K-12 educators, introduction of underrepresented students to environmental STEM fields, and engagement with policymakers and the public on soil pollution issues. This award reflects NSF's focus on expanding fundamental knowledge and understanding of integrated Earth systems through basic research in the atmospheric, earth, and ocean sciences.
