The fabrics that fill our homes, from natural cotton towels and bedsheets, to clothes produced with synthetic materials, produce microscopic fibers as they break down over time. Previous research has shown that household washers collect and release these microfibers into the environment, and now a new studyย uses citizen science to demonstrate how dryer vents also produce microfibers under normal household use.ย ย
This summer, DRI brought eighteen students from Truckee Meadows Community College (TMCC) to our Reno campus for a paid, immersive research experience. Over the course of the ten week program, students worked under the mentorship of DRI faculty members to learn about the process of using scientific research to solve real-world problems. This unique internship program welcomes all students, not only those pursuing majors in science. ย
DRIโs Monica Arienzo, Director of the Microplastics and Environmental Chemistry Laboratory, was recently awarded $250,000 by the Department of Defense to investigate laundering and textile degradation as a possible source of PFAS and microplastic pollution. The one-year grant will fund laboratory studies and analysis led by Arienzo, with DRIโs Daniel Saftner and Yeongkwon Son contributing to the work. Matt Reeves of Western Michigan University is partnering with the DRI scientists for the project.ย ย
An examination of Rocky Mountain snow finds higher contamination levels of mercury and others metals in the northern part of the range, consistent with increased current and historical mining in the region. The study, published in the May issue of the journal Environmental Pollution, examined contamination levels for Mercury, Zinc, Cadmium and Antimony from nearly 50 sites in the Rocky Mountains.
A new study published in Nature Communications utilizes insights gleaned from DRIโs Mountain Rain or Snow project to evaluate why traditional weather forecasting struggles to identify the rain/snow transition line. The research was possible because thousands of community members across the U.S. contributed more than 40 thousand observations of the type of precipitation falling at their location.
DRI scientists Guo Yu, Meghan Collins, Monica Arienzo, and Anne Heggli co-authored a new study that examines how Mountain Rain or Snow is helping improve weather forecasting models. The citizen science project collects observations of precipitation from community volunteers across the country to further scientific understanding of the environmental variables impacting where precipitation falls as either rain or snow. This information is critical for informing avalanche forecasting, road safety, and water resources management.
This summer and fall, DRI brought twelve students from Nevadaโs community and state colleges to the Las Vegas and Reno campuses for a paid, immersive research experience. Over the course of the 16-week program, students worked under the mentorship of DRI faculty members to learn about the process of using scientific research to solve real-world problems. This unique internship program welcomes all students, not only those pursuing majors in science, who are in their first or second year of enrollment at local state and community colleges.
DRI scientists are recruiting fifteen Fallon residents with private wells to participate in a water quality study. All fifteen study participants will receive free water quality results, and a subset of the well owners will receive water filtration systems.ย The research will be used to identify the spatial extent and potential sources of contaminants such as pesticides, microplastics, and flame retardants and quantify the efficacy of treatment systems to reduce concentrations in drinking water.
The $100,000 grant will fund the production of additional educational kits known as Greenboxes that raise awareness and understanding of the prevalence and role of microplastics in the environment. In addition to the Greenboxes, the grant will also support community partnerships with The Nature Conservancy, the Walker Basin Conservancy, Get Outdoors Nevada, Sierra Nevada Journeys, and Envirolution.
New research explores the microbial communities that live on plastic waste and how they impact the 2nd most biodiverse river in the world. DRI researchers Monica Arienzo and Rachel Kozloski are co-authors on this new study that examines the ecological impacts of plastic waste in Cambodiaโs Mekong River.
