2013 22 elements in moss samples in Portland, Oregon
The data were collected by using a grid-based sampling strategy in which sample points were randomly placed on roads within a grid that covered most of Portland. The location of sampling points on private property is slightly offset to protect privacy.
We provide these data so that scientists, regulators, and citizens can further investigate the importance and possible sources of the toxic hotspots identified by the moss samples.
