Brief Summary of Minutes of Annual Meeting

NC 1022 Annual Meeting Notes November 3, 2009 Philadelphia Convention Center Participants Dan Strawn, Jim Harsh, Dick Loeppert, Ron Turco, Nancy Cavallaro, Alvin Smucker, Daniel Gimenez, Xia Kang, Paul Bloom, Lyle Prunty, Don Sparks. Jim Harsh gave introduction: Purpose of meeting was to discuss proposal objectives, elect leadership, and assign task for proposal writing to be completed by Dec. 1, 2009. Positions: Jim Harsh was nominated Chairman of the group. Daniel Gimenez was nominated vice-chair. Dan Strawn was nominated secretary. Objectives were edited. Post-meeting Jim Harsh circulated an e-mail of revised objectives and asked for feedback. Principal changes to objectives were to eliminate the active pursuit of a synchrotron facility and broaden the focus of the group of to promote all advanced analytical methods of particles related to agricultural activities. Dan Strawn suggested that the purpose of forming a multi-state group is two-fold: 1) advise analytical instrument developers and operators of the needs of our discipline, and 2) educate and help each other to utilize advanced analytical tools. Large national facilities include PNNL, APS, SSRL and NSLS II. However, many labs (University-based and federal) have specialized analytical expertise that could be incorporated into group activities. There was some discussion of using a Web-based editing program to work on proposal. As the time is short, unless the web-based editing is implemented very soon, Strawn suggested using Word to track changes. All participants need to complete Appendix E and submit to AES by November 15. Proposal Assignments: Gimenez agreed to work on project outcomes. Bloom, Bertsch, Strawn, Sparks were assigned to lead methods. Harsh is coordinating the effort. Strawn worked on Accomplishments Within proposal, Working Groups section from old proposal will be removed. A discussion of the need for the group to exist needs to be developed. This should follow the two-fold purpose suggested above by Strawn. There are funds for a conference to be held. Target was summer 2010, however concern over the conflict with WSSC and noted short planning time were raised. It was proposed to request an extension to 2011. Alvin Smuckers is organizing the conference. All attendees paid $5.00 to Ron Turco to pay for meeting facility.

NC1022 : The Chemical and Physical Nature of Particulate Matter Affecting Air, Water and Soil Quality. (NCR174) Jim Harsh Presiding Officers elected: Jim Harsh- Chair, Daniel Gimenez- vice-chair, Dan Strawn- Secretary No technical presentations were given because members presented papers in the annual meetings of the Soil Science Society of America Developed objectives for new proposal and outline. Assigned task for writing new proposal. NC-1022 Tasks for 2010 1. Finalize new Project proposal. 2. Organize Bouyoucos Conference gathering for soil scientists specializing in synchrotron radiation techniques to be held in 2011. (See attached copy of full minutes) Accomplishments: Members of the group used synchrotron spectroscopy and microscopy to better understand the biogeochemical reactions occurring on particulates in soils and air. Results from the groups research are providing better remediation strategies, improved agricultural practices, and protection of soil resources. Beamtime at the synchrotron facilities is obtained by peer-review of proposals. Group members have applied for beamtime and been allocated time at all of the major facilities. Utilizing the beamlines provides impetus for beamline scientists and engineers to design the capabilities of the beamlines to accommodate environmentally relevant samples. Publishing in highly regarded journals helps raise the stature of group members, making our beamtime request proposals more likely to be awarded. Group members have published numerous papers in international research journals on molecular speciation and transformation of chemicals associated with environmental particles. This work includes, but is not limited to, studies of metals, metalloids, and xenobiotics availability to plants and microorganisms as affected by particle-element interactions; toxicity and uptake of nanoparticles; bioavailability of plant; distribution and speciation of particle-associated elements in soil; transformations of metals and compounds on particle surfaces, adsorption of organics to soil minerals; mobility of colloids and nanoparticles in soils; and the role of soil particle surface on aggregation of soil particles and macro- and micro-porosity of soils.
