The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Microplastics in the aquatic environment.” Experts from across academia, government and industry are here to answer questions on this topic. Microplastics are in the news regularly, but what do we know about them specifically? Researchers will be presenting on the ecological impacts generally, on oysters, from tires; they will explore how to remove microplastics in wastewater treatment, and so much more. Please note that we are asking members of the society who represent researchers from a variety of disciplines and sectors; the answers are not official SETAC positions. We encourage discussion and debate! Just please keep it professional. For more information on SETAC see http://www.setac.org Post your question and the organizers of the conference will find someone to answer it as soon as possible. Answers to questions will be most active during the session break at 3PM-4PM EST and immediately following 5PM-6:30PM EST, ending at 6:30PM EST.
