Computational Modeling of Microplastics to Assess Environmental Fate and Transport

Learn about the environmental impact and modeling of microplastics in this 18-minute conference talk from the Georgia Water Resources Conference. Explore current research on plastic pollution, focusing on microplastics (less than 5mm) and nanoplastics (less than 100nm) that have become ubiquitous in our environment - from polar regions to drinking water sources. Discover how household products contribute to microplastic pollution through items like microbeads in cosmetics and polyester clothing fibers. Examine computational modeling approaches used to track environmental fate and transport of these particles in waterways, including horizontal and vertical transport patterns, distribution gradients, and ocean-biota-coastal interactions. Gain insights into existing models, emerging technologies, and their limitations while understanding the challenges in standardizing microplastic extraction methods and analysis. Review preliminary data, technological solutions for removal, and future research directions needed to address this growing environmental concern projected to reach 12,000 million metric tons in landfills and natural environments by 2050.
