• ORNL ESD researchers studying mercury were prominently cited in a 3-day series of articles in the Knoxville News Sentinel, written by Frank Munger. The 12 articles in the series can be viewed at http://blogs.knoxnews.com/munger/2012/01/wrap-up-on-mercury-project.html. Interviewed scientists including Liyuan Liang, Scott Brooks, Steven Brown, Jeremy Smith, Teresa Matthews, Mark Peterson, John Smith, and Mike Ryon. Interviews with Gary Jacobs and Thom Mason highlighted the value of ORNL mercury research. The series of articles appeared to be a balanced overview and has been well received by those concerned about the mercury contamination issues in Oak Ridge.

Field Pilot Tests

As guided in projects, flow management test and chemical reduction with the use of stannus tin chloride were demonstrated in following report:

• Evaluation of new options for reducing mercury release

Chemical reduction and volatilization of Hg are intended to reduce mercury loading from point discharge. The results have been sumarized in the following report:
