Book Description
Written by a multidisciplinary group of scientists from around the globe Environmental Restoration of Metals-Contaminated Soils provides a summary of the current environmental remediation technology. Topics include: Physical-Chemical processes for in situ remediation by adding amendments for stabilization The mechanics of metal retention and release from soils Chemical remediation method for soil contaminated with CD and Pb The effect of soil pH on the distribution of metals among soil fractions Physical and electrical separation methods for soil remediation Relationship between the phytoavailability and the extractability of heavy metals An overview on environmental restoration of Se-contaminated soils Trace elements in the soil-plant system under tropical environment The process of metal removal by chelation using amino acids The effects of natural zeolelite and bentonite on the phytoavailability of heavy metals Metal uptake by agricultural crops from sewage-sludge treated soils In many cases an integrated approach to the remediation of metals contaminated soil yields the best results. Environmental Restoration of Metals-Contaminated Soils explores the emerging issues of the biogeochemistry of trace elements in the environment and provides an approach combining elements from biology, geochemistry, hydrology, and soil physics and chemistry.

Book Description
In Russia's Far East sits the wild Ussuri Kray, a region known for its remote highlands and rugged mountain passes where tigers and bears roam the cliffs, and salmon and lenok navigate the rivers. In this collection of travel writing by famed Russian explorer and naturalist Vladimir K. Arsenyev (1872-1930), readers are shuttled back to the turn of the 20th century when the Russian Empire was reeling from its defeat in the Russo-Japanese War (1904-1905) and vulnerable to its Far Eastern neighbors. What began as an expedition to survey the region's infrastructure for the Russian military turned into an adventure through a territory rich in ethnic and ecological diversity. Encountering the disappearing indigenous cultures of the Nanai and Udege, engaging the help of Korean farmers and Chinese hunters, and witnessing the beginning of indomitable Russian settlement, Arsenyev documents the lives and customs of the region's inhabitants and their surroundings. Originally written as "a popular scientific description of the Kray," this unabridged edition includes photographs largely unseen for nearly a century and is annotated by Jonathan C. Slaght, a biologist working in the same forests Arsenyev explored. Across the Ussuri Kray is a classic of northeast Asian cultural and natural history.

Book Description
The dramatic journeys of the 19th century Gold Rush come to life in this geologist’s tour of the American West and the events that shaped the land. In 1848, news of the discovery of gold in California triggered an enormous wave of emigration toward the Pacific. The dramatic terrain these settlers crossed is so familiar to us now that it is hard to imagine how frightening—even godforsaken—its sheer rock faces and barren deserts once seemed to them. Hard Road West brings their perspective vividly to life, weaving together the epic overland journey of the covered wagon trains and the compelling story of the landscape they encountered. Taking readers along the 2,000-mile California Trail, Keith Meldahl uses settler’s diaries and letters—as well as his own experiences on the trail—to reveal how the geology and geography of the West shaped our nation’s westward expansion. He guides us through a landscape of sawtooth mountains, following the meager streams that served as lifelines through an arid land, all the way to California itself, where colliding tectonic plates created breathtaking scenery and planted the gold that lured travelers west in the first place. “Alternates seamlessly between vivid accounts of the 19th-century journey and lucid explanations of the geological events that shaped the landscape traveled.”—Library Journal

Book Description
"Rough-Hewn Land tells the geologic story of the American West--the story of its rocks, rivers, mountains, earthquakes, and mineral wealth, including gold. It tells it by taking you on a 1000-mile-long field trip across the rough side of the continent from the California coast to the Rocky Mountains. This book puts you on the outcrop, geologic hammer in hand, to explore the evidence for how the spectacular, rough-hewn lands of the West came to be. When North America broke free from Eurasia and Africa some 200 million years ago, it triggered a cascade of violent geologic events that shaped the West we see today. As the west-moving continent crunched across the seabed of the ancient Pacific, islands and assorted pieces of ocean floor collected against its prow to build California--and plant gold there too. Meanwhile, mountains squeezed upward from California to Colorado, and vast quantities of molten rock seeded the crust with precious metals while spewing volcanic fire across the land. Later, the land stretched like an accordion to form the washboard-like Basin and Range province and Great Basin within it, while California began to crackle along the San Andreas fault. Throughout the West today, a near-constant drumroll of earthquakes testifies to a world still reshaping itself in response to the ceaseless movements of the Earth's tectonic plates. Rough-Hewn Land weaves these stories into the human history of the West. As we follow the adventures of John C. Frémont, Mark Twain, the Donner party, and other historic characters, we see how geologic forces have shaped human experience, just as they direct the fate of the West today"--
