Using moss to detect air pollution in Portland, Oregon: details of a groundbreaking study

Rob Mangold, Director, Pacific Northwest Research Station, USDA Forest Service
Sarah Jovan, Research Ecologist, USDA Forest Service
Katie McClintock, Air Enforcement Officer and Julie Wroble, Toxicologist, US EPA Region 10

In February, findings from a Forest Service study created a stir throughout the city of Portland, Oregon. Researchers had assessed whether mosses found on urban trees could be used to measure air pollutant levels, and their groundbreaking methodology identified previously unknown sources of toxic heavy metals. The maps created by the study team gave state regulators new information they could use to site air quality monitors within the city. The state’s independent monitoring confirmed high pollutant levels at one particular hotspot—cadmium and arsenic levels were 47 and 155 times higher than state benchmarks, respectively. Using moss as a bioindicator to monitor environmental health had never been done in an urban setting, and the study has generated intense interest from residents, state and local government, the US EPA, and the media. The work has received months of local news coverage and was featured in the New York Times. Our panel of speakers will provide an overview of the cadmium study and describe how it presents an intriguing prospect for the way regulatory agencies monitor air quality in cities.
