The lack of SO2 detection by TEGA does not prove the absence of MgSO4. The reactions in TEGA with Ca may have prevented the volatilization of any SOx species.

Additional Comments:
1. Most recent results show the pH in the WCL solution to be ~ 7.7
2. ClO4- was not the dominant anion in solution. Most recent results show that SO4= and HCO3- dominate at 2-3x the ClO4-.
3. The fact the no organics were detected by TEGA can be attributed to the presence of 0.6 % ClO4- in the soil, which would most likely oxidize any organics as the TEGA temperature was ramped above 200C.

About once a month at Sigma Xi headquarters, we liven up the lunch hour with an American Scientist Pizza Lunch talk. In these informal lectures, scientists describe new research to nonscientists. The series is light on jargon but heavy on solid science. Each Pizza Lunch offers an in-depth look at its subject, whether it's bedbugs or the smart grid. Click below to read about and download these talks -- and to subscribe!
JSTOR, the online academic archive, now contains complete back issues of American Scientist from its inception in 1913 (as Sigma Xi Quarterly) through 2005.
The table of contents for each issue is freely available to all users; those with institutional access can read each complete issue.
