Since 1998, The Contaminated Site Clean-Up Information (CLU-IN) website has presented Internet Seminars covering a wide variety of technical topics related to hazardous waste characterization, monitoring, and remediation. For select seminar topics offered since 2012, we are making complete video recordings available through our archives. This feed contains all video seminars archived in the last 12 months. For a complete list of seminars archived since 2000, please visit http://www.clu-in.org/live/archive/. Our Rehabilitation Act Notice for reasonable accommodation is available at http://www.clu-in.org/training/accommodation.cfm. CLU-IN was developed by the U.S. Environmental Protection Agency (EPA) but is intended as a forum for all waste remediation stakeholders.

Evaluating Plant Uptake of Chemical Contaminants in Crops Grown Near Urban Gardening Sites for Human Health Risk Assessment (Aug 9, 2023)
This document provides an assessment of the potential exposure routes, plant uptake pathways, and remediation practices of chemicals contaminants found in crops grown in urban gardening sites. This report will focus on both inorganic and organic pollutants that are considered contaminants of emerging concern (CECs) by the U.S. EPA. The presence of several trace elements and persistent organic pollutants (POPs) in urban soil media were analyzed on the state-level to quantify the potential contamination risk associated with plant uptake mechanisms by crops commonly grown throughout the various regions of the U.S. CECs exposure routes in urban agriculture (UA) scenarios and associated human health risks are assessed. This report also serves to provide potential remediation methods for polluted urban soils, with an emphasis on affordability, accessibility, and sustainability of the methods. The specific aims of this report will utilize the existing methods used to quantify the concentrations of chemical contaminants in urban soil media to identify regional trends and produce a best practices guide for urban growers. A portion will be dedicated to outlining research gaps which require remediation in order to facilitate a more accurate characterization of potential exposure of CECs to ensure enough data is provided to form national screening levels.
