The National Science Foundation awarded a $408,896 Project Grant to Virginia Polytechnic Institute & State University under the Engineering federal grant program (CFDA 47.041) to investigate micro- and nanoplastics in sea spray. Over a five-year period from June 2022 through May 2027, Virginia Tech will conduct an integrated experimental and modeling project to quantify the aerosolization of micro- and nanoplastic particles from oceans and seas via sea spray generation mechanisms. The...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research to investigate the impact of plastic-derived dissolved organic carbon on ocean biogeochemistry and the biological carbon pump. The $569,435 award to Northeastern University will utilize a combination of laboratory experiments, field sampling, and numerical modeling to explore how bacteria consuming plastic-derived organic matter could compete with phytoplankton for key nutrients...
This $478,560 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports research by a multidisciplinary team from Cornell University and the University of Aberdeen in the UK. The project aims to unravel the formation and impact of the "plastisphere" - a unique microbial habitat that forms on microplastics in soil. The researchers will examine how microplastics age in different soils, track spatial and temporal changes in...
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...
The National Science Foundation (NSF) awarded a $600,000 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to Virginia Polytechnic Institute & State University (Virginia Tech) for a project titled "CAS-SC: Tuning Hydrocarbon Products from Temperature-Gradient Thermolysis of Polyolefins and the Subsequent Upcycling to Functional Chemicals." The project aims to develop techniques for converting common plastic waste, such as polyethylene (PE) and...
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 (NSF) Division of Environmental Biology awarded a $160,215 Project Grant to Pennsylvania Western University (PennWest) to study the role of microplastics in altering microbial communities and metabolic processes in a freshwater lake environment. The project, titled "RUI: Physiological Heterogeneity of Plastic-Associated Microbial Communities in Freshwater Lake Lacawac - Microplastics, Which are Plastic Particles Less Than 5 Millimeters in Size, are a Common...
This National Science Foundation (NSF) Project Grant under the Geosciences program (CFDA 47.050) will support a collaborative research project that investigates the impact of plastic-derived dissolved organic carbon (PDOC) on the ocean's biological carbon pump. The $665,899 award, effective from April 1, 2025 to March 31, 2028, will fund laboratory experiments, field sampling, and numerical modeling to test the hypothesis that bacteria consuming PDOC in surface waters draw down key nutrients...
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,...
This $399,836 National Science Foundation (NSF) Social, Behavioral, and Economic Sciences (CFDA 47.075) Project Grant awarded to Texas A&M University on September 1, 2024 supports research examining the sources and spatial distribution of microplastics in rivers. The project involves analyzing sediment samples from diverse watersheds to characterize the "microplastic fingerprint" of each river and investigate how land use patterns impact microplastic emissions. Key products and...
