How can Municipal Governments in Metro Vancouver Reduce the Amount of 6PPD-Q Entering Fish-Bearing Watercourses?

Abstract

This paper was originally written for Dr. Anna Hippmann’s Environmental Science 201W course Environmental Science in Practice. The assignment asked students to pose an environmental science research question and answer it by reviewing the relevant literature. The paper uses APA citation style.

This paper reviews the body of literature concerning the tire antidegradation compound N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD) and its ozonated transformation product, N-1,3-Dimethylbutyl-N′-phenyl-p-quinone diamine (6PPD-Q) to assess the effectiveness and limitations of mitigation measures municipal governments in Metro Vancouver could adopt to protect aquatic ecosystems – and coho salmon (Oncorhynchus kisutch) in particular – from harms associated with these compounds. Based on the literature reviewed, a layered defense that avoids and contains tire wear particles, and filters urban runoff, is recommended as a 6PPD-Q mitigation strategy.
