Lecture 3 - Microplastic Pollution in Marine and Freshwater Ecosystems Featured Speaker: Austin D. Gray, Ph.D.; Assistant Professor of Biological Sciences; Virginia Tech Date: Thursday, June 29th Time: 6pm – 7pm Cost: FREE Sponsored by Jennifer & Forrest McConnell and Jennie Stowers. Plastic pollution poses one of the greatest global risks to freshwater and marine ecosystems. The formation of microplastics from plastic debris has been shown to alter aquatic ecosystems by disrupting biota populations. In this talk, topics surrounding plastic pollution, microplastic occurrence and distribution, toxicological impacts of microplastics, toxicokinetic aspects of microplastic uptake and depuration, and microplastic formation rates in marine and freshwater habitats will be discussed.
