Cover: Microplastics and Environmental Chemistry

Microplastics and microfibers are small particles of plastic that have either degraded from larger plastic items or originated from primary microplastic pollution sources (such as microbeads in cosmetics). Microplastic pollution is an area of emerging concern because of the ubiquity of particles in multiple environments and their persistence in the food chain. In the laboratory experiment , Laura Rowe, Maria Kubalewski, Robert Clark, Emily Statza, Thomas Goyne, Katie Leach, and Julie Peller discuss how first-year undergraduate chemistry students quantified the amount of microplastics and microfibers in their local soil during a 2- or 3-week mini-research project. As shown on the cover, the students combined density gradient separation and the Fenton reagent with filtration and microscopic identification to visualize the microplastic pollution they unearthed.

From the Archives: Celebrating the International Year of the Periodic Table 

With 2019 marking the 150th anniversary of the periodic table of chemical elements, this year has been proclaimed the "" by the United Nations General Assembly and UNESCO. There are many resources in the Journal for making the most of this year’s celebration. A great place to start is Erica Jacobsen’s comprehensive listing of JCE resources from October 2009 and before in:

.
