Humic Substances in the Global Environment and Implications on Human Health
Advances in the chemistry and biochemistry of humic substances: isolation, characterization, functions; humic substances in soil and crop production; humic substances in aquatic and sedimentary systems; interactions of humic substances with organic and inorganic xenobiotics and with organisms; applicative aspects of humic substances: industrial and medical issues.
Humic Substances II
Based on the Second International Conference of the International Humic Substances Society held in Birmingham, England, in 1984, this compendium reviews ways of studying the structure and function of humic substances, including the use of both degradative and nondegradative processes. Also considers nitrogen in humic substances, humic molecules and the interactions between humic and other substances.
Aquatic Humic Substances
Here is a cohesive compilation of recent research results into the many aspects of water purification. Major sections cover the characterization and environmental impact of aquatic humic substances, their reactions in natural water and sediments, and their influences on water treatment. Topics examined include hazardous waste chemicals, water solubility enhancement, sorption, metal speciation, and photochemistry. Specific types of treatment processes are also described.
Humic Substances in Soil and Crop Sciences
Conversion factors of SI and non-SI units. An introduction to soil humic substances. Variations between humic substances isolated from soils, stream waters, and groundwaters as revealed by 13C-NMR spectroscopy. Synthesis and degradation of natural and synthetic humic material in soil. Selected methods for the characterization of soil humic substances. Nitrogen in humic substances as related to soil fertility. Roles of organic matter, minerals, and moisture in sorption of nonionic compounds and pesticides by soil. Effects of humic substances on plant growth. Ecological aspects of soil organic matter in tropical land use. Humic and fulvic acid fractions from sewage sludges and sludge-amended soils. Application of nuclear magnetic resonance spectroscopy to whole soils. Humic substances in soil and crop sciences: an overview.
