Bioaccessibility of Chromium (III & VI)
Melanie Stewart

There are numerous Department of Defense sites that are contaminated with toxic metals such as Cr. Ingestion of contaminated soil by children is the usual risk driver motivating remediation. This study investigated the effect of soil properties on the bioaccessibility of Cr(III) and Cr(VI) as a function of metal concentration and aging, and sought to develop statistical models based on common soil properties to estimate the bioaccessibility of Cr in soil. The A- and upper B- horizons of 36 DOD relevant soils from 7 major soil orders were treated with Cr(III) and Cr(VI) and allowed to age. The bioaccessibility of the contaminated soils was measured using a physiologically based extraction test (PBET) designed to simulate the digestive process of the stomach. Overall, bioaccessibility of Cr decreased as the duration of exposure to the soil increased. Cr bioaccessibility varied widely as a function of soil type with most soils limiting bioaccessibility to <30% after 100 d aging. Statistical analysis showed that the bioaccessibility of Cr(III) on soil was correlated with the clay content, TIC content, and pH of the soil with bioaccessibility decreasing as the soil TIC content and pH increased and as the clay content decreased. The model should be useful for assessing Cr(III) and Cr(VI) bioaccessibility at contaminated site so that the appropriate remediation criteria can be determined.
SEPTEMBER, OCTOBER AND NOVEMBER
MEETING SUMMARIESby Carla Sparks
The September meeting of the ETGS and the The East Tennessee Chapter of AIPG was held at Spicy's in the Old City - a new location for ETGS. The Fall Field Trip (formerly the Spring Field Trip) was discussed, and votes were cast for the trip date. Voting was left open for member unable to attend the meeting for 5 days following the meeting. The trip was help on Saturday, September 29. For a complete description of the trip, see the September News Klippe.
Dana miller presented information on detecting climate change using soil carbonate C and O isotopes and organic carbon isotopes from vertisols in coastal Texas. For a complete abstract of this presentation, please see the September News Klippe.
The October meeting was held at Ryan's Family Steakhouse in Knoxville. Unfortunately, all potential speakers were unavailable for this meeting.
The November meeting was again held at Spicy's in the Old City. Upcoming elections were discussed.

Lets look at some rocks (and maybe some flowers, too)!
Betsy Gorisch has volunteered to lead the ETGS fall field trip on one of the following Saturdays:
· September 22,
· September 29, or
· October 6.Cast your votes at Tonight's meeting at Spicy's in the Old City or send it in by e-mail to geofolks@worldnet.att.net . Votes must be in by close of business on Friday, September 14.
The trip will begin at Boyd Gap along US Highway 64 at the head of the Ocoee River and will proceed to Ducktown, TN where a visit to the mining museum is planned. From Ducktown, the trip will continue (generally) along Highway 64 and will include several stops at rock outcrops where the rocks have enjoyed a range of metamorphic conditions (green schist to granulite facies). The trip will culminate at Winding Stair Gap in NC where granulite facies rocks are exposed. Come on out to think about rocks for a Saturday.
If you still need persuasion, take a look at some of the pictures taken along the course of the upcoming trip. Cast your vote for a date by Friday the 14th.

THE WILDERNESS CENTER "ROCK WALK"
by Carla Sparks
ETGS was contacted by Rudy Tekaucic in May, a representative of The Wildernes Center in Wilmot Ohio. He requested the assistance of ETGS in creating a "Rock Walk" at the Wilderness Center. Mr. Tekaucic provided a description of the Wilderness Center and their project; to review this information, please see the May News Klippe.
I recently contacted Mr. Tekaucic to see how the project was going. The "Rock Walk" premiers on Saturday, September 22nd. It currently has over 40 specimens, and the group hopes to add more in the next serveral months. Mr. Tekaucic plans to photograph the "Rock Walk" debut and send us photographs as a preview.
The Wilderness Center is still looking for samples. If you might be able to assist in this project, you can contact Mr. Tekaucic directly at:

UT OFFERS 1-HOUR CONTINUING EDUCATION COURSE
by Dr. Bill Dunne
edited by Carla Sparks
In consultation with members of the alumni Board of Advisors, the University of Tennesee Geology Department has developed a one-credit CEU to better serve the professional needs of local geoscientists in the Knoxville area. The CEU is approved by the University and has a requirement that a participant attends 10 Klepser Lecture Series seminars during the academic year (10 seminars from over 20 seminars offered from the Fall through Spring semesters. See the article below in the current News Klippe or visit http://geoweb.gg.utk.edu/Geology/News/News.html for the list of currently scheduled seminars in the Fall 2001 semester).
We know that many local geoscientists need to maintain professional registrations that require a certain number of CEU's per year. We hope that from a selection of over 20 seminars, including our student presentations (which I personally believe to be better than our outside speakers on average!!), you will be able to find 10 that interest you or relate to your work.
The seminars are on Thursday afternoon from 3:30 to 5:00pm, typically with cookies beforehand. They are located in the Walls Lecture Theatre (Room 302) in the Geological Sciences Building. The best bet for parking is probably the multistory carpark adjacent to the University Student Center (check the University webpage, www.utk.edu, for a map). CEU requirements are to attend 10 seminars, sign in for each one, and then complete a yellow registration card after the 10th seminar. The department will collect the yellow cards and then pay the $8 charge per card for processing.
We hope to see some of you attending these seminars and please spread the word to colleagues who might be interested in this option.
For further information, you may contact Dr. Bill Dunne at wdunne@utk.edu.
