In the Pacific Northwest, Salmon hold significant ecological, economical, and cultural importance. They are a significant part of cultural identity for many Columbia River Basin tribes (Importance of Salmon – Pacific Coast<\/a>). For several Pacific Northwest salmon species, returning to spawning grounds may pose previously unknown and deadly threats. Mass salmon die-off events have been linked to roadway runoff and a particular toxicant that comes from leachate from tire tread wear particles. The compound, called 6PPD-quinone, is an oxidation product of an additive intended to prevent damage to tire rubber from ozone (6PPD-quinone in Science<\/a>).

Miranda Jackson is a fourth year PhD student in the labs of Stacey Harper and Manuel Garcia-Jaramillo in the department of Environmental and Molecular Toxicology at OSU. She is a self-described aquatic ecotoxicologist, and she\u2019s been investigating the toxins making their way into our surface waters and eventually salmon habitats. Her research involves investigating the toxicity of micro and nano-sized rubber particles and 6PPD-quinone that are derived from car tires, elucidating their mechanisms of toxicity in various fish species, and working on remediation strategies for removing 6PPD-quinone from the environment. <\/p>\n\n\n\n

Tune into KBVR 88.7 FM <\/a>at 7 pm PST on April 13th to hear Miranda talk about the impressive and scary toxicity of 6PPD-quinone (that also somehow is incredibly species specific to salmonids), how to remove these toxins from the environment, and what we can do to limit it from the source.
