title: Data for Messager et al. 2020 STOTEN - Low-cost biomonitoring and high-resolution, scalable models of urban metal pollution

description: Published in Science of the Total Environment - https://doi.org/10.1016/j.scitotenv.2020.144280<br><br>Last updated: 2021/01/05<br>Please notify the author of any anomaly in the dataset or accompanying metadata and scripts<br>Purpose: In this study, we demonstrate novel scalable methods to monitor and predict urban metal pollution at high resolution (&lt; 5 meterm) across large areas (10,000‐–100,000 km2) to guide pollution reduction and stormwater management. We showcase and calibrate predictive models of Zn, Cu, and a synthetic index of pollution for the Puget Sound region of Washington State, U.S. We also exemplify their transferability across the entire United States.We leveraged widely and freely available datasets of car traffic characteristics and land use as predictor variables and trained the models with biological monitoring data of metal concentrations in epiphytic moss from &gt; 100 trees based on new rapid and low-cost protocols introduced in this study. <br>Reference compendium DOI: 10.6084/m9.figshare.13518593Github repositories:- https://github.com/messamat/traffic (R - Downloading and formatting Bing Traffic REST API)- https://github.com/messamat/stormwater_samplingPy (Python - Geographic data pre- and post-processing)- https://github.com/messamat/stormwater_samplingR (R - data analysis)<br>--------------------------------------------------------------------------------<br>COMPENDIUM CONTENT--------------------------------------------------------------------------------1.
