It has been nearly one year since IISG set sail on Lake Michigan to sample for plastic pollution. Since then, Sam Mason, a chemist from State University of New York Fredonia, and her research team have been hard at work analyzing those water samples. The initial results are revealed in the latest edition of IISG’s interview series UpClose.  
 
In this issue, Mason talks about her ongoing work to quantify plastic pollution in the Great Lakes for the first time. In addition to the Lake Michigan results, Mason discusses plastic levels in the other four lakes, explains how plastics could impact aquatic wildlife, and suggests additional research needed to understand this emerging contaminant. 
 
This is the sixth edition of UpClose, which takes readers behind the scenes of the latest research on pharmaceuticals and personal care products. Each interview targets a different component of PPCP research—everything from what happens to pharmaceuticals when water is treated to what bacterial resistance could mean for other aquatic wildlife living in urban rivers. Readers also get an insider’s view of the complex, and sometimes tricky, process of conducting field studies, and the potential implications of research on industries and regulations.

Join the Invasive Crayfish Collaborative for an exciting webinar featuring Dr. Chris Taylor from the Illinois Natural History Survey who will provide an overview of midwestern crayfish habitat requirements, feeding, reproductive biology, and life-history.Crayfishes in the Midwest occupy almost every type of aquatic and semi-aquatic habitat in the region. They function as critically important components of those ecosystems and in many cases represent a majority of invertebrate biomass. As “keystone” species, understanding their biology and roles in ecosystems is critically important. Register for the webinar at InvasiveCrayfish.org/events1 Or the link in bio.
