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, valued at $558,556.00 and granted by the National Science Foundation's (NSF) Engineering program (CFDA 47.041), supports research to study the fate and transport of microplastics and their interactions with halogenated organic compounds (HOCs) in soil and groundwater environments. The key objectives are to: (1) evaluate the impacts of aged and weathered microplastics on HOC adsorption and kinetics; (2) assess the impacts of weathering and aging of HOC-adsorber...
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...
This Project Grant award of $231,803 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to study microplastic sources, sinks, transport, and environmental impact across the Finger Lakes watershed in New York.
