Talk summary:

Freshwater and coastal ecosystems near urban areas are subject to multiple stressors, including the impacts of pollution. In particular, chemicals used in consumer products and industrial practices can negatively impact aquatic ecosystems when they are washed down the drains in our homes and workplaces, and when rain carries them from outdoor surfaces into storm drains and then into receiving waters. Of increasing concern are contaminants found in road runoff, including the tire rubber byproduct known as 6PPD-quinone, which is acutely toxic to coho salmon. This presentation will focus on 6PPD-quinone fate in urban stormwater, and the potential for green infrastructure systems to mitigate the impacts of toxic road runoff contaminants.
