Brief Summary of Minutes of Annual Meeting

NC-1187 Meeting November 3, 2014 Long Beach Residence Inn 1. Attendees are listed in the "Participants" section. Because of the location and conflicting meetings, there were a few members who were not able to make it to the meeting. They did, however, interact with the chair or advisor on site to contribute to discussion items. 2. Project NC-1187 requires a proposal for renewal this year. As a result, the meeting was used to discuss desired changes in the new proposal and milestones for new products. It was noticed that the objectives in the posted proposal are not ours and Harsh will contact Christina Hamilton to get it fixed. 3. The group decided to leave the first objective as is and add detail to others. 4. One objective needs to emphasize spatial and temporal scales and pushing the limit of resolution below nm scale. 5. Be sure to specify opportunities at the new Brookhaven light source. Emphasize the new capabilities and state that we will take advantage of lines as they become available starting Fall, 2015. 6. Keep the milestone to produce a “white paper” that can serve as a seed to seek extramural funding. Need to decide to whom this should be addressed. 7. Plan for a symposium in Minnesota that emphasizes use of synchrontron sources but also other state of the art capabilities applicable to particle behavior and characterization. This could be a joint symposium including soil chemistry, soil physics, and/or soil mineralogy. Dan Strawn is chair of Soil Chemistry; Markus Flury Chair of Soil Physics; Daniel Hirmas Chair of Soil Mineralogy. 8.Keep milestone of multi-investigator proposal for group. 9. Daniel Gimenez will draft the proposal and send by email to all participants for comments before submitting.

Outputs: 1. A soot particle aerosol mass spectrometer (SP-AMS) was used to measure the chemical composition of particulate emitted by gasoline and diesel vehicles at high time resolution and allowed distinction between carbon derived from fuel and lubricant sources. 2. For improved chemical characterization of the organic composition of ambient particulate matter, a combined thermal desorption aerosol gas chromatograph-aerosol mass spectrometer (TAG-AMS) was developed allowing simultaneous and complementary measurements of quantitative organic mass loading and detailed organic speciation. With a high-resolution time-of-flight mass spectrometer (HR-ToF-MS), elemental-level determination of OA oxidation state and improved compound identification and separation of unresolved complex mixtures are enabled. Such measurements will improve the identification of organic constituents of ambient aerosol and contribute to the ability of atmospheric chemistry models to predict ambient aerosol composition and loadings. 3. A patent was applied for describing a nanocomposite structure for a sensor that can serve as a building block for surface enhanced Raman scattering substrates. 4. To improve exposure characterization of resuspended aerosol PM, a mobile sampler--"Pre-toddler Inhalable Particulate Environmental Robotic (PIPER)"--was developed. Measurements of PM and its constituents with PIPER are more strongly associated with asthma, eczema and wheeze compared with measurements using SIMs. Application of this methodology may provide useful insights into early childhood exposures related to the etiology of childhood illnesses associated with inhalation exposures. 5. A stepwise, multiobjective, multivariable automatic calibration method for the Agricultural Environmental Policy eXtender (APEX) model for simulating runoff, sediment, total phosphorus (TP), and total nitrogen (TN) was developed. This is a cost efficient technique that should be of significant benefit to modelers. 6. Researchers developed, calibrated, and validated a fuzzy rainfall-runoff model using long-term data of three adjacent field scale row crop watersheds (1.65-4.44 ha) with intermittent discharge in the claypan soils of Northeast Missouri. The fuzzy rainfall-runoff model has the potential for runoff predictions at field-scale watersheds with minimum input. It also could up-scale the predictions for large-scale watersheds to evaluate the benefits of conservation practices. 7. An environmentally benign remediation method was found effective for phenol and heavy metal removal from contaminated water. The product is a combination of corn cob silica, alginate, and bacteria immobilized into beads. 8. Several studies examined the basic science of colloid transport in the vadose zone. a. An examination of the role of fracking flow-back fluids in colloid mobilization from sand showed that the fluid remobilized in situ colloids via 1) surface tension reduction and steric repulsion and 2) slow kinetic disaggregation of colloid flocs. Increasing the flow rate of the flowback fluid mobilized an additional 36% of colloids, due to the expansion of water filled pore space. This study suggests that hydrofracking fluid may also indirectly contaminate groundwater by remobilizing existing colloidal pollutants. b. Transport and retention of polyvinylpyrrolidone (PVP)-coated silver nanoparticles (PVP-AgNPs) were investigated over a wide range of physicochemical factors in water-saturated columns packed with an Ultisol rich in clay-size particles. The transport and retention of PVP-AgNPs are highly sensitive to physicochemical factors, but mathematical modeling was found to accurately predict the fate of these ENPs in porous media. c. Redistribution of E. coli within soil aggregates was studied as a function of management practices. E. coli movement in soil aggregates was mainly driven by water flow via capillary forces and redistribution was most pronounced in conventional tillage aggregates, followed by no-till, and was almost negligible in native vegetation soil aggregates. d. A geocentrifuge was use to determine if water content or flow rate is more important for colloid transport. Negatively charged polystyrene colloids (220 nm diameter) through unsaturated sand-filled columns under steady-state flow at different water contents and flow rates. Colloid transport decreased with decreasing water content, and below a critical water content, colloid transport was inhibited, and colloids were strained in water films. The flow rate affected retention of colloids in the secondary energy minimum, with less colloids being trapped when the flow rate increased. These results confirm the importance of both water content and flow rate for colloid transport in unsaturated porous media and highlight the dominant role of water content. 9. Other research within NC-1187 considered the distribution and characterization of aerosol particles over urban and rural areas. One showed the importance of vehicle lubricants was an important contributor to organic aerosols in addition to fuels. Another examined organic matter in the atmosphere above Bakersfield, Pasadena, Tijuana, and on board the R/V Atlantis. They found that 60-88% of the total OM was attributed to fossil fuel burning. Additional marine, vegetative detritus, and biomass burning or biogenic sources contribute up to 40% of the OM. A study of aerosol amines over a southeastern U.S. forested site and a polluted midwestern site. Amines were concentrated on particulate matter, were dependent on temperature and biomass burning events, and were higher at the polluted site. The study concluded that gas to particle conversion was a concentration determining process at the forested site and the importance of anthropogenic emission sources. 10. The dispersion of Fe from deep sea vents was studied from the perspective of Fe-organic complexes. It was found that Fe is scavenged and taken up by microorganisms providing the source of organic matter for complexation. The authors state "cellular iron uptake is a major process in plume microbial communities and suggest new mechanisms for generating Fe-C complexes. This 'microbial iron pump' could represent an important mode of converting hydrothermal iron into bioavailable forms that can be dispersed throughout the oceans." Another study involving Fe-organic interactions showed that Mariprofundus ferrooxydans, which produces strands of ferrihydrite, may use extracellular polysaccharides as templates for ferrihydrite precipitation which is then followed by adsorption of dissolved organic carbon preserving the morphological structure of the Fe mineral. There were no new milestones or activities in 2014.
