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 National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant, awarded to Iowa State University on August 15, 2024 for $299,999.00, will support fundamental research to understand the physical processes involved in the trapping of microplastic particles in riverbeds. The research leverages synergistic pore-resolving direct numerical simulations and theoretical modeling to reveal the microscopic effects at the pore-level and derive predictive models for microplastic...
This Project Grant award for $231,803 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a collaborative research project to study microplastic sources, 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 engage college sophomores in a 5-week field research experience to collect and analyze microplastic samples from air, water, soil, and organisms....
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $180,000 to conduct research on wildfire-generated nanoparticles and their impact on human health and the environment. The research aims to: 1) determine how temperature, composition of combustible materials, and soil composition influence the metal chemistry of fine particulate matter; 2) identify the mineralogy, metal associations, and morphology of these particles; and 3) examine how...
The National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded Purdue University a $459,529 project grant under the Engineering (CFDA 47.041) federal grant program. The grant will fund research from August 2021 through July 2024 to investigate the multiphase chemistry of air pollutants from cured-in-place pipe installations and their potential to serve as an unrecognized source of atmospheric micro- and nano-plastics. As part of its mission...
The National Science Foundation awarded a $100,079 project grant to support research titled "ENVIRONMENTAL SOURCE APPORTIONMENT AND SOIL-HOUSEHOLD DUST RELATIONSHIPS OF URBAN METAL POLLUTANTS ACROSS DIFFERENT REGIONS AND SEASONS." The place of performance for the research is Crows Nest, Indiana.
The grant is part of the NSF's Geosciences program (CFDA 47.050), which aims to expand fundamental knowledge of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Specifically, the awarded research will conduct environmental source apportionment and analyze relationships between urban metal pollutants in soil and household dust across different regions and seasons. The period of performance for the research is August 1, 2021 through September 30, 2022.
