Dear Colleague Letter: Critical Aspects of Sustainability (CAS): Micro- and Nanoplastics (MNP)

NSF has released a Dear Colleague Letter (DCL) asking for proposals that tackle the fundamental scientific questions underlying micro- and nanoplastic characterization, behavior, and reactivity in the environment (including animal and human health), as well as their elimination from land and water systems.

This is an effort spanning several Directorates and Divisions across NSF but we’ve highlighted DEB’s specific call below:

The Division of Environmental Biology (BIO/DEB) welcomes inquiries that explore basic questions in the ecological and evolutionary sciences. Microplastics represent a relatively new and poorly understood component of ecosystems that may alter fundamental biological processes from cells to ecosystems. In this context, projects that seek to improve understanding of the role of microplastics in fundamental ecological and evolutionary processes will be prioritized. Projects with a primary focus on toxicology will not be considered. PIs interested in submitting an EAGER or RAPID proposal should send a 1-2 page research concept outline to the BIO representative listed below. This prospectus will be used to determine if an invitation to invite a full EAGER or RAPID proposal is warranted. A prospectus is not necessary for submission of a regular core proposal. Please consult the current DEB core solicitation ( for a detailed description of programs within the division.”

Please send your research concept outline and any questions you may have to John Schade at
