  • Characterizing the nature of heavy metal release reactions, sorption mechanisms, and movement in the soil is the main topic of this book. Because soils are heterogeneous, heavy metals in soils can be involved in a series of complex chemical and biological interactions including oxidation-reduction, precipitation and dissolution, volatilization, and surface and solution phase complexation. The heterogeneous nature of the different soil constituents adds to the complexity of interactions of heavy metal species with the soil environment....

  • This paper presents the results of soil characteristics study and orientation for rational and sustainable use of major soil types in Thai Thuy District, Thai Binh Province, where is facing many environmental problems. The interactive process between river, sea and human activities over time has resulted in the characteristics of 10 soil types, which are grouped in 4 main classes (acid sulfate soil, saline soil, alluvial soil and sandy soil). They have been used for agricultural production (mainly for rice and other crops growing).

  • Enzymes that function within plants, animals, and microorganisms are fundamental to life, and their contributions to metabolic pathways and processes have been studied extensively. For over 100 years there has been interest in what today is called ecological or environmental enzymology. This aspect of enzymology originates from the work of Woods, who, in 1899, wrote about the survival and function in soil of plant peroxidases following their release from decaying plant roots.

  • The planet is a marvelous place with its blue skies, wild storms, deep lakes, and rich and diverse ecosystems. The tides ebb and flow, baby animals are born in the spring, and tropical rain forests harbor an astonishing array of life. The Earth sustains living things and provides humans with the resources they need to maintain a bountiful way of life. These resources include water, soil, and nutrients to grow food, and the mineral and energy resources to build and fuel modern society, among many other things....

  • A large amount of information has accumulated on humic acids and related substances, which warrants the creation of an independent science of humic compounds. Two different concepts have emerged from the maze of data, one claiming humic compounds to be operational or fake compounds, produced by the analytical extraction procedures, and the other considering them to be natural compounds occurring in soils, rivers, lakes, oceans and their sediments.

  • For much of history, few things have mattered more to humans than their relations with soil. This is evidenced by a rich historical literature on aspects of soil management and soil fertility, dating back to texts of ancient civilizations of the Middle East, the Mediterranean, China, and India (see McNeill and Winiwarter 2004).

  • This volume aims at providing a coherent presentation of recent developments and understanding of heavy metal reactivity in soils. Such an understanding is necessary in addressing heavy metals concerns in the environment. The implicit framework of multiple reactivity acknowledges the widely known role played by the various colloidal surface functional groups in concomitant reactions. This overarching frame of reference allows unification between molecular structure-reactivity relationships at one scale and transport processes at the other....

  • The book deals with several aspects of soil erosion, focusing on its connection with the agricultural world. Chapters' topics are various, ranging from irrigation practices to soil nutrient, land use changes or tillage methodologies. The book is subdivided into fourteen chapters, sorted in four sections, grouping different facets of the topic: introductive case studies, erosion management in vineyards, soil erosion issue in dry environments, and erosion control practices.

  • The ribbon itself forms an abstract letter ‘W’ (for World) that changes colour from pink through blue into a green that represents a green economy. The person’s position in the ribbon is where the colour incidentally transitions into green, signifying that people – you – are central to a functional green economy and thus it must include you. The light green part of the ribbon curves into a slight horizon of the earth.

  • In earlier times, people did not think about the impact of their actions on the environment and on future generations. Mankind hunted certain animals out of existence; damaged or destroyed ecosystems to build industrial plants, buildings, homes, and other developments; polluted the air and waterways; and negatively impacted the health of human beings.
