19th International Conference of
International Humic Substances Society

Humic Substances and Their Contribution to the Climate Change Mitigation

16-21 September 2018
Albena Resort, Bulgaria


Invited Speakers


Department of Chemistry, Lomonosov Moscow State University, Russia
Title: “Chemical patterns of Humic Substances and Natural OM in diverse environments”
Topic 1 “Environmental Chemistry – Dynamics - Contribution of Humic Substances and Natural Organic Matter to Climate Change Mitigation”

Research experience
More than fifteen years of work in the field of humic substances research. Main areas of interest – structure, reactivity and detoxifying ability of humics toward heavy metals and organic ecotoxicants. Particular outcome – development of the common strategy of numerical description of the structure of natural organic substances of variable composition and irregular structure on the example of humic substances. The novelty of the research: new technique for calculation of the corrected elemental composition of humic substances; new technique for determination of the functional groups with a use of 1H NMR spectroscopy and an approach to calculation of fragmental composition of HS basing on the H- and C-distribution; experimentally proven choice of polydextrans as molecular weight markers for SEC-determination of molecular weight distruibution of HS; the quantitative estimates of complexing, binding and detoxifying properties of a broad set of humic substances of different origin (about 100 samples) to heavy metals, PAHs and atrazine. Classification of humic substances and prognostic modelling of their properties.

Prof. Lars TRANVIK

Uppsala University, Sweden
Title: Ecology and biogeochemistry of dissolved organic matter in inland waters   
Topic 3 “Water Quality - Drinking Water – Surface Waters”
Lars Tranvik is a professor of limnology at Uppsala University since 1999. Currently he shares his time between research and some teaching at the Limnology program, and is Head (“Prefekt”) of the Department of Ecology and Genetics.
He does his research together with a group of PhD students, postdocs, and senior scientists covering a broad range in expertise. They focus on biogeochemistry and microbial ecology, in particular the carbon cycling of inland waters.

Prof. Teodoro MIANO

DISSPA , University of Bari, Italy 
Title: Determination of Humification Degree in Peat Profiles
Topic 4 “Soil Physical Chemistry -  Soil Fertility
Teodoro M. Miano is a Professor of soil chemistry, University of Bari, Italy.

His main research interests are: Soil organic matter and humic substances in soil, natural and industrial biomasses, waters and their interactions with pesticides, degradation products and and various metal ions. Molecular and functional characterization. Humification processes. Compost and composting. Environmental role of natural organic matter. Soil fertility and quality management. Organic agriculture. Paleo-climatic and paleo-environmental reconstruction with implications on the past anthropic activities specifically related to undisturbed ombrothropic peats.
Prof. Dan OLK

Title: “Can humic products substantially improve ecosystem quality and economic yield?
Topic 5Humic Based Technologies and Crop Production Quality”
Dan Olk is a soil biochemist with the U.S. Department of Agriculture-Agricultural Research Service and works at the National Laboratory for Agriculture and the Environment in Ames, Iowa. He is a Ph.D. graduate of the University of California, Davis (1993) and worked for eight years at the International Rice Research Institute in the Philippines before his employment with the USDA-ARS (2001-present). Since 2009 Dr. Olk has conducted field evaluations of humic products in maize─soybean rotations of the U.S. Midwest, studying the efficacy of humic products for improving crop growth as influenced by environmental variables, including annual weather patterns and soil type.  Field research has also addressed responses by maize structural biochemistry and root growth to humic products.  His laboratory research has used an integrated extraction of physical and chemical fractions of soil organic matter to link seasonal changes in their masses and biochemical natures to crop production and soil nutrient cycling in field conditions.
