NEWSLETTER
INTERNATIONAL HUMIC SUBSTANCES SOCIETY
Number 33
Dear IHSS members, Autumn will again be time for elections: all of you will be asked to choose candidates and vote to renew the positions of Vice President, one Board Member and Treasurer of the Society. Your active participation is once again vital to make the IHSS Board truly representative of the IHSS membership. The good functioning of the Society depends on its officers and this honour and duty should be decided in turn by the largest possible number of the membership. The regular renewal of all Board positions was wisely delineated in our bylaws by indicating in Article V, Section 4 the maximum number of years each officer should serve. However, during the past years it has become increasingly clear that the position of Treasurer is different from the others. This position requires not only dedication in terms of both time and effort, which few of us would be prepared to spare, but also a specific knowledge of laws as well as of tax regulations. It also has become increasingly evident for undeniable practical reasons, that the Treasurer should practically be a person living in the USA; it would be complicated for anyone outside the USA to deal with the financial administration of a Society based in the USA. It would also be exceedingly costly and time consuming to regularly shift from country to country the legal location and bank accounts of the Society. For these reasons the Board of Directors asked our well-known, trustworthy Treasurer Ed Clapp to agree to be a candidate and to serve again for another term. We are all very obliged to him for accepting and be willing to go on serving the IHSS as Treasurer. Together with the ballots for the next elections you will therefore receive another ballot which will contain a request to agree to a change in Article V, Section 4 of the bylaws, which will read as follows: "An officer, except the President, the Vice President/President Elect and the Treasurer, may hold the same office for no more than two (2) additional consecutive terms. No officer, except the Treasurer may serve more than twelve (12) consecutive years on the Board of Directors". The old text was:" An officer, except the President and the Vice President/President Elect, may hold the same office for no more than two (2) additional consecutive terms. No officer may serve more than twelve (12) consecutive years on the Board of Directors". We hope to get the necessary support from the membership and allow our Society to avail itself of Ed's invaluable expertise for some more years. Maria De Nobili
President of IHSS

BOARD ACTIVITIES

2005

BOARD MEETING, JUNE 2005 The last Board meeting was held after the EMSI/NOM workshop, on June 17 and 18, 2005 in Columbus, Ohio, USA. Many topics were discussed during the meeting: · Elections in 2005: voting for the renewal of the positions of Vice President, one Board Member and Treasurer of the Society. It was decided that concomitantly to the next elections, the membership will be asked to vote a change in bylaws to allow the present Treasurer of the society to be re-elected. Details are given in the President`s introduction on page 1. · 13
th

meeting of IHSS in Karlsruhe, 2006: Gudrun Abbt Braun reported on behalf of the

organizing committee about the arrangements made for the conference. Information can be found in the first announcement and call for papers on page 16 of this newsletter and on the website www.wasserchemie.uni-karlsruhe.de/ihss2006/. · · Reference and Standard Collection: the Board has decided upon a new reference sample from Antartica. Detailed information is given on page 7. National Chapters: Among the items discussed during the last Board meeting was the ever increasing need for transparent and democratic organization of the larger chapters. Due to the continuing increase in Collection sales, the IHSS is in good financial standing. We are able to spend more money for Collection sample renewal and for bursaries and to contribute to the activities of Regional and National Chapters. This makes it important to set up clear rules for management and organization of Chapters with more than 50 members. The President suggested that following the example of the Nordic/Baltic Chapter, the IHSS should encourage the National Chapters to develop bylaws and hold regular elections of National Coordinators. To encourage participation from their members, the President proposed that up to 50% of the membership dues should be retained by Regional or National Coordinators for the organization of National Chapter meetings or to encourage students (prizes, bursaries, etc). These suggestions were approved by the Board.

IHSS STANDARD AND REFERENCE COLLECTION
New Reference Sample from the Antarctica At the recent meeting of the IHSS Board we approved a grant of $21,000 to purchase supplies and help support a graduate student for a sampling trip to Antarctica to obtain 50 g of fulvic acid (FA) for the Collection, from Pony Lake. The IHSS funding is supplementary to a major grant from the US National Science Foundation to a team led by Yo Chin of The Ohio State University and Diane McKnight of the University of Colorado. They will be leaving in December 2005 to do the sampling. Pony Lake is in an environment that lacks higher plants and there is no input from soil organic matter to the lake. The FA from Pony Lake represents a zero terrestrial input end-member of aquatic NOM and it has no input of lignin residues. The importance of this type of FA derives from the fact that because no higher plants can grow in this environment the FA is derived from alga and microbes. Samples of microbially-derived fulvic acid from Lake Fryxell in the McMurdo Dry Valleys in South Victoria Land, Antarctica were isolated during an earlier trip in the late 1980's. The C13 nuclear magnetic resonance (NMR) spectra of fulvic acids from Lake Fryxell showed a predominance of aliphatic and carbohydrate carbons. Although a large decrease in the DOC concentration occurred during the transition to ice-free conditions (from 7.7 to 2.7 mM), the changes in the DOM fractionation were relatively small. The nitrogen content of all fulvic acid and transphilic acid fractions decreased significantly during the transition and the delta(15)N values became heavier for all fractions. The only discernible change in the C-13 NMR spectra of all the fractions was a decrease in a peak in the region corresponding to amide carbons. These results suggest that preferential loss of N-containing molecules of fulvic acids and transphilic acids are associated with the considerable loss of DOM in midsummer .The reference sample that they will prepare for IHSS will be isolated from DOM in Pony Lake, Cape Royds, Antarctica. The Pony Lake fulvic acid is similar to the Lake Fryxell sample and the site has several advantages in terms of the logistics involved in collecting a large volumes sample: · · · · · high DOC concentrations (30-95 mgC/L); about 20% of the DOC is fulvic acid based on our previous studies, protected status because of its location near a historic hut (Shackleton's hut from the 1907 expedition), documentation of lake ecosystem condition being similar in the past, based on studies conducted by the biologist on the 1907 expedition, ice-free conditions with significant wind-mixing in summer, proximity to McMurdo Station, the large US research base with a modern analytical laboratory.

In the developing the plan for the larger volume collection, the group worked with the environmental group of the US Antarctic Program. To prepare the new reference sample, the water will be filtered on site and then pumped to the helicopter pad and shipped by helicopter sling load to the Crary Laboratory at McMurdo Station for processing. This approach will minimize the environmental problems associated with processing the sample in the field, such as disposing of the effluent and operating a larger camp. Fulvic Acid from Elliot Soil Recently Michael Hayes and his group at Limerick University completed the extraction and preparation of our third batch of FA from the Elliott soil. This sample will replace the current batch of Elliott soil FA when it is sold out in about a year from now.

IHSS MEMBERS NEWS
Dr. Robert (Bob) L. Wershaw retired in March, 2005 from the U.S. Geological Survey after 41 years of employment. His research project "Organic Polyelectrolytes" encompassed humic substances in soil, sediment, and water as well as other components of natural organic matter and their interactions with various contaminants. Beginning with some of his original attempts to measure the occurrence and fate of organic pesticides in the environment, this research quickly translated into studies of the interaction of these pesticides with natural organic matter in soils, sediments, and water. As little was known about the chemical and physical structure of natural organic matter, Bob focused on original research on organic matter structure that became a basis for understanding partitioning interactions between various organic contaminants and natural organic matter. This structural model described organic matter molecules assembling as a bipolar membrane structure on soils and sediment surfaces, and as aggregate colloids in aqueous suspension. The physical structural properties of natural organic matter are currently a topic of significant research interest, and Bob's career research on this topic has made him an acknowledged leader in this field. Bob has maintained a research interest in the fate of contaminants in the environment as evidenced by his recent research on organic arsenicals fed to poultry and the fate of these arsenicals in poultry wastes disposed on soils as fertilizer. All of these research endeavors relied on a fundamental understanding of organic biogeochemistry, through scholarship, tenacity, and a unique ability to select critical research fields that have been ignored by the researcher community. Bob's major scientific activity after retirement has been to promote and organize open access electronic publication of environmental research.

PhD Thesis
Assessment of Concentration and Fractionation Methods for the Structural Characterization of Dissolved Organic Matter in Waters
MÝller, Margit B. UniversitÄt Karlsruhe (TH), July 2004, Supervisor: Prof. Dr. Fritz H. Frimmel Engler-Bunte-Institut, Division of Waterchemistry, D-76131 Karlsruhe, Germany Abstract Dissolved organic matter (DOM) is ubiquitous in all aquatic systems. Both the composition as well as the concentration of DOM in natural waters are highly variable and are functions of the origin, formation conditions, and age, i.e. the degree of biogeochemical modification of the precursor material. Components of the DOM can be of natural as well as of anthropogenic origin. In most aquatic systems, compounds of natural origin form the major part of the DOM. Among these, humic substances (HS) are the most abundant ones and therefore play an important role in aquatic systems as well as in water technology. Molecular size and structure of the DOM components are key parameters for understanding their behavior both in aquatic environments and in water treatment processes. The aim of this work therefore was to investigate the structural composition of various molecular size fractions of DOM of different origin. For this purpose, two samples representative of different precursor materials and of a different degree of modification were selected: a humic-rich sample of natural origin from the brownwater lake Hohloh in the Northern Black Forest, Germany and an effluent from the wastewater treatment plant of the city of Karlsruhe, Germany (anthropogenic origin). Size exclusion chromatography (SEC) and multi-stage ultrafiltration (mst-UF) were used as fractionation methods. The structural composition of the DOM fractions was investigated using Spinning Nuclear Magnetic Resonance Spectroscopy ( C MAS NMR). The preparation of samples which are suitable in amount (mass) and composition (relative content of organic carbon) for

C MAS NMR analysis requires a concentration of the sample before

fractionation. From the three concentration methods which were compared (adsorption onto XAD8resin, rotary evaporation, and ultrafiltration), ultrafiltration was the most suitable method because it resulted in the highest DOC recovery and also in a removal of inorganic salts from the sample. A comparison of the fractionation methods SEC and mst-UF showed that SEC is superior to mstUF both in terms of separation efficiency and reproducibility. The separation efficiency was evaluated by investigating the molecular size distribution of SEC and mst-UF fractions from the same sample using asymmetric flow field-flow fractionation (AF4). Fractionation by SEC, however, has the drawbacks of diluting the sample and of introducing inorganic salts into it due to the use of
INTERNATIONAL HUMIC SUBSTANCES SOCIETY

a buffered eluent. This requires an additional sample preparation step before NMR analysis to remove the salts. For the brownwater sample, similar trends regarding the relative content of certain structural groups were observed for the SEC and mst-UF fractions: The relative content of carbohydrates and methyl groups was highest in the fractions of nominally large molecular size and decreased with decreasing size. On the other hand, the relative contents of branched aliphatic carbon, branched O-alkyl carbon, and COOR carbon increased with decreasing size. Based on extensive data which are available for the brownwater sample in the literature and on an extended interpretation of the NMR data, independent information on the molecular size of the sample components could be deduced. It was concluded that the average molecular size of the majority of the DOM components indeed did decrease from nominally large to nominally small fractions. Hence, in addition to yielding information on the structural composition of the fractions, this extended interpretation of the NMR data also confirmed that with both fractionation methods a separation according to different hydrodynamic radii (Re) could be achieved. Fractionation experiments with both the wastewater effluent and with selected model compounds, however, showed that interactions between the separation medium (SEC column, UF membrane) and sample components can negatively affect the separation according to different Re values. This demonstrates that the above mentioned conclusion therefore is, however, only valid for the investigated brownwater sample and the experimental conditions used in this study. The structural data for the brownwater fractions which have been determined in this work are useful for future studies regarding, e. g., the removal of certain fractions by different water treatment processes such as flocculation, adsorption onto activated carbon, or membrane filtration and also for the investigation of the interaction of DOM fractions/components with other water constituents. The structural data are therefore useful with respect to both water technologyoriented and scientific studies of the brownwater DOM. Publications · MÝller, M. B., Schmitt, D., Frimmel F. H.

A 2005, 109, 2223-2232); 2) evidence that HSs have selective affinity for prion proteins extracted from TSE-infected hamster brains, implying that SOM can immobilize prions; 3) further information on energy transfer between HS-bound lanthanide ions that monitors step-wise complexation and consequent HA conformational changes; 4) a report on the large EC HUPA project coordinated by Dr. Gunnar Buckau of Karlsruhe, Germany; and 5) a summary by Steve Cabaniss of an agent-based computer simulation of humification in which the choice of precursor molecules (tannins, terpenoids, lignins, etc.) and reaction conditions (light, pH, oxygen levels) leads to different HS products with properties consistent with field and laboratory studies. The quality of the presentations was very high and the discussion was lively. We thank the authors for attending and sharing their thoughts on future HS&T Conference themes.

5th North Central NOM Workshop held at Ohio State University The US IHSS Chapter was one of the sponsors of the 5th North Central NOM WORKSHOP hosted by the The Ohio State University's Environmental Molecular Science Institute (EMSI), in Columbus, Ohio, USA, 15 - 17 June, 2005. Sixty scientists attended the workshop, including the IHSS Board of Directors who held their annual meeting after the workshop. The keynote speaker was Dr. Norbert Hertkorn. of the GSF Research Center for Environment and Health in the Institute of Ecological Chemistry in Germany. His topic was "Molecular level structural analysis of natural organic matter - an exercise in defining complexity." A session on functions of NOM featured a presentation by Dr. Yona Chen of the Hebrew University of Jerusalem entitled, "The role of dissolved organic matter in metal binding and plant growth". The first IHSS US chapter business meeting was conducted by the new Coordinator, Dan Olk. The idea of Chapter meetings every few years was discussed and the participants agreed it is a good idea to have technical meetings. These meetings might be conducted with other group meetings, possibly with a research group like the EMSI, with a regional meeting, or with a national meeting of a professional society. Paul Bloom

IHSS Participates in the 15th Annual V.M. Goldschmidt Conference IHSS was one of the sponsoring societies for the 15th Annual V.M. Goldschmidt Conference that was held at the University of Idaho in Moscow, Idaho, USA on May 20-25, 2005. The Goldschmidt Conference is the premier annual meeting in geochemistry and mineralogy. In recent years low temperature geochemistry in soils, groundwater, and surface water, has become very prominent in these meetings. The organizing committee invited IHSS to participate by organizing a symposium. More than 1500 scientists from 34 counties attended the conference. The organizers did an incredible job to accommodate the needs of this size conference in Moscow Idaho, which has a population of only 22,000. Meals and entertainment events were held on the University campus with an excellent selection of food, inexpensive microbrews and wine. The IHSS sponsored symposium, "NOM-metal complexation and the mobility of metals" was organized by Vice President Paul Bloom and Past President Yona Chen. The symposium included 11 oral papers and 2 posters. Keynote speakers were Ed Tipping of the Lancaster Environment Centre, UK, and Marc Benedetti of UMR CNRS, Paris, France. Other invited speakers were George Aiken of the US Geological Survey and Mike Perdue, Georgia Technological University, USA. Willem van Riemsdijk, Wageningen University, The Netherlands, was also invited but unable to attend because of an injury in a bicycle accident shortly before the meeting. More than 60 people attended the symposium, despite being scheduled on the last day. The number of conferees interested in humics was no doubt influenced by the other symposia related to biogeochemistry including one entitled "Dissolved organic matter and its interaction with trace metals and organic pollutants in natural waters", and several focusing on microbial interactions with minerals. The IHSS organizers also had a booth in the exhibits hall to promote membership and our 2006 meeting in Karlsruhe. Paul Bloom, Yona Chen

VI Brazilian Meeting on Humic Substances
18 to 20 November 2005. Rio de Janeiro, Brazil The Brazilian Meeting on Humic Substances (EBSH) started in 1996, and was followed by the second meeting in 1997. Since then it became a biannual scientific event, promoted by the Brazilian Chapter of IHSS. The EBSH aggregates researchers working in humic substances and organic matter including chemists, agronomists, physicists, engineers and biologists, contributing with approximately 100 papers to each EBSH. Discussions are conducted on subjects such as characterization of humic substances and their role in both terrestrial and aquatic ecosystems. The 6th EBSH will be held in the Rio de Janeiro city between 18 and 20 November 2005. Embrapa Soils will be the host institution in collaboration with the Federal Rural University of Rio de Janeiro (UFRJ), Catholic University (PUC Rio), State Northeastern Fluminense University (UENF) and Embrapa Agrobiology. The EBSH will focus on the use of humic substance products in agriculture and water treatment as well as those aspects related to the general knowledge of humic substances and human sciences. The program of the EBSH6 is available on the web page: www.cnps.embrapa.br/ebsh6.
