Sommario/riassunto |

Besides live biomass and decaying dead biological matter, humus constitutes an important component of organic matter in the soil. Humic substances are heterogeneous polymers formed during the process of decay and degradation of plant, animal, and microbial biomass. The humic fraction of organic matter is a stable nutrient base that serves as a slow-release source of carbon and energy for indigenous, slow-growing microorganisms in the soil. This book discusses recent advances and applications of humus and humic substances in agriculture, industry, and the environment. Chapters address such topics as the chlorination and phenanthrene sorption for humic and fulvic acids extracted from different soils, humic substances as growth promoters for farm animals, dynamics and function of humus from tropical forests, and much more. |

Sommario/riassunto |
|
This publication unites all of the OECD documents related to Good Laboratory Practice and compliance monitoring, and, in the Annex, reproduces the three OECD Council Decisions related to the Mutual Acceptance of Data in the Assessment of Chemicals. It includes the international standards for quality of non-clinical environmental, health and safety data on chemicals and chemical products in a regulatory context—the OECD Principles of Good Laboratory Practice—and supporting Consensus and Advisory Documents on their interpretation and application. The OECD guidance documents for governments on monitoring compliance with the Good Laboratory Practice Principles are also included. This publication thus presents the state of the art on |
