Creosote is a pesticide typically derived from coal tar and used to treat wood products like railroad ties, telephone poles and submerged pilings. Creosote is a complex mixture of thousands of chemicals, particularly polycyclic aromatic hydrocarbons (PAHs) and their derivates, many of which are carcinogenic and harmful to aquatic organisms. One major challenge in the regulation and management of complex mixtures like creosote is understanding which constituents in the mixture drive toxicity. This presentation will describe strategies to investigate mixture toxicity at a legacy creosote site using the biological responses of model organisms to field-collected mixtures to guide inquiry rather than a predetermined list of suspect chemicals.

The Environmental Speaker Series is free and open to the public. Talks are held each Thursday at 4:30pm in Academic Instructional Center West, room 204. Join us at WWU or online on Zoom!

Visiting Assistant Professor, Western Washington University

Ian Moran is a newly appointed Visiting Assistant Professor in the Department of Environmental Sciences at Western Washington University. He conducted his PhD research at Oregon State University leveraging passive chemical samplers and embryonic zebrafish to investigate the occurrence, movement and toxicity of chemical mixtures at contaminated sites in Oregon and Alaska. As an alumnus of the College of the Environment Ian is excited to be back on campus to teach toxicology courses this year!
