Phytoremediation + arsenic + Rufus Chaney

The thread on phytoextraction of arsenic by fern in
contaminated soils was on SANET in March 2001.

Next, the question arose.....

"what is done with these hyper-accumulating plants after
they've sequestered heavy metals from contaminated
soils and mine spoils"?

It was was posed to Dr. Rufus Chaney, scientist for USDA-ARS
on heavy metals, bioremediation, phytoremediation, composts,
and biosolids.

His informative reply was posted back to SANET,
so you can just read the web archives.

Rufus Chaney is with the USDA-ARS Laboratory known
as Animal Manure and by-Products Laboratory.  You can
view titles of research projects and papers highlighting
Chaney's work at the following websites.

This Kitchen Gardening article showed data on how much
arsenic was found in vegetable garden soils within a few
inches away from CCA-treated lumber used to make raised
beds, versus arsenic levels in soils further away.  This is a
good article on this topic.

Hazardous Waste Clean-Up Information (CLU-IN) | EPA
is a key website at EPA for remediation topics, databases,
and documentation.

The EPA document on arsenic treatment technologies:

Arsenic Treatment Technologies for Soil, Waste, and Water
EPA 542-R-02-004

"This report contains current information on the treatment
technologies for wastes and environmental media containing
arsenic. It summarizes information on 13 technologies used
to treat arsenic, identifies sites and facilities where arsenic
treatment has been used, and provides references to more
detailed arsenic treatment information...  Two technologies
discussed in the report address soils, other solids, and water:
electrokinetics and phytoremediation."

Bioremediation and phytoremediation topics come up
now and again, so I just keep track of what Rufus Chaney
and EPA put out.

Earlier this year I posted a list of phytoremediation
resources on the Permaculture list.

It contains key web-based resources on phytoremediation from
U.S. Environmental Protection Agency and the Missouri Botanical
Garden.  These include introductory fact sheets, technology
handbooks, and resource guides.

The following Internet seminar was an interesting
example of web-based technology; e.g., you can
put on a live Internet seminar with Audio and Slides,
and then your panel can interact with participants
through call-in questions.   These slides shows
are a fast way to learn about a topic, too.

Phytotechnologies:  An Internet Seminar | May 15, 2001
Sponsored by ITRC,EPA, BP Amoco, and RTDF
Content:  An online slide show featuring 60 slides and
lecture notes; available in HTML and PDF formats.
