    Humic substances, the remarkable brown biomaterials in animals, coals, plants, sediments, soils and waters, are crucial components of the carbon cycle and other life processes. Thus greater knowledge and understanding of these versatile materials is of great importance to the productivity, health and safety of the world's ecosystems, humans, land and water. Summary. The field of humic matter research has undergone drastic changes in concepts and principles since the first edition of Humic Matter in Soil and the Environment: Principles and Controversies was published more than a decade ago. Still the only book of its kind specifically addressing humic acid principles and controversies, the Second Edition presents the newest advances in humic acid.

    Properties of humic substances. Humic acids - the fraction of humic substances that is not soluble in water under acidic conditions (pH 2) but is soluble at higher pH can be extracted from soil by various reagents and which is insoluble in dilute acid. Humic acids are the major extractable component of soil humic substances. This book contains 23 papers discussing the various aspects of humic substances, viz., (i) composition and structure, (ii) interaction with xenobiotics, (iii) interaction with trace metals, and (iv) modelling organic colloid-facilitated transport of contaminants.

    Humic acid is not a humic substance. This article has many serious problems, starting from its name. Apparently "humic substance" is a relatively rarely used term and concept, which refers to compounds present in untreated humus; whereas "humic acid", "fulvic acid" and "humin" are not "humic substances", but compounds derived from humus by chemical treatment. Humic substances, humin, extraction, fractionation, XAD resins, proton and 13 C NMR. Introduction In the classical definitions soil humic substances (HS) are defined as amorphous, polymeric, brown coloured substances that are differentiated on the basis of solubility properties (Hayes and Swift ) into humic.

As a service to all scientists who are interested in humic substances, we have compiled a list of reference books dealing with humic substances in soils, sediments, and natural waters.

We need input from readers to keep this list up-to-date. If you know of a good book that should be on this list, please inform [ ]. The lack of such provided the inspiration for Humic Substances and Chemical Contaminants.

Humic substances, in the past called “gelbstoff” or yellow compounds, are the end points of marine, freshwater, and soil organic polymer compounds, they are highly varying combinations of organic molecules (carbohydrates, amino acids, and fatty acids) and are also highly resistant to.

Humic substances are organic compounds that are important components of humus, the major organic fraction of soil, peat, and coal (and also a constituent of many upland streams, dystrophic lakes, and ocean water).For a long era in the 19th and 20th centuries, humic substances were often viewed through a lens of acid–base theory that described humic acids, as organic acids, and their.

Humic substances (HS) are major components of the natural organic matter (NOM) in soil and water as well as in geological organic deposits such as lake sediments, peats, brown coals and shales.
