It is hard to stop sending updates about  the Portland moss study but the PNWRS Donavan, Jovan et al.  did a beautiful job with the supplementary report and interactive page.  Their website about this study is a very nice example of colorful, attractive communications and easy data access to promote a science-based understanding of urban air quality.   Check out the interactive Web map of metal profiles in Portland.   I understand Rick Graw (R6 air program) provided a timely review, nice!
