This book was released on 2002 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency is developing Ecological Soil Screening Level (Eco-SSL) benchmarks for ecological risk assessment of contaminants at Superfund sites. Benchmarks for invertebrates Were developed from existing literature. Insufficient information for Ba, Be, Mn, and Sb to generate Eco-SSLs necessitated standardized toxicity testing to fill the data gaps. We used the Enchytraeid Reproduction Test (ERT) with Enchytraeus crypticus in this study. This test was selected on the bases of its ability to measure chemical toxicity to ecologically relevant test species during chronic assay, and its inclusion of at least one reproductive component among the measurement endpoints. Tests were conducted in Sassafras sandy loam soil, which supports relatively high bioavailability of metals. Aging/weathering procedures for amended treatment soil were incorporated into the study to better reflect the "real world" exposure conditions. The toxicity order based on juvenile production was Be> Mn> Sb> Ba with EC20 values of 45, 116, 194, and 585 mg kg-1, respectively. These results show that ERT is a robust and sensitive assay for toxicity assessments and is appropriate for the Eco-SSL development.

This book was released on 2002 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (USEPA), in a collaborative effort with other Federal agencies, states, and private industry, is developing Ecological Soil Screening Levels (Eco-SSLs) for ecological risk assessment of contaminants at Superfund sites. Earthworm (Eisenia fetida) cocoon production and survival tests were conducted in a Sassafras sandy loam soil that supports relatively high bioavailability of barium (Ba), beryllium (Be), manganese (Mn), and antimony (Sb). For the metals tested, cocoon production was a more sensitive endpoint than was survival. Bounded Lowest Observed Effect Concentrations (LOECs) (mg kg-1) for cocoon production, as determined by analysis of variance (ANOVA), were 83, 86, 433, and 1236 for Be, Sb, Ba, and Mn, as compared to LOECs for survival of 110, 697, 1585, and 2222, respectively. Bounded No Observed Effect Concentrations (NOECs) (mg kg-1) for cocoon production, as determined by ANOVA, were 57, 60,258, and 1111 for Be, Sb, Ba, and Mn, as compared to NOECs for survival of 83, 617,1348, and 1444, respectively. Non-linear regression analysis of cocoon production data showed that the relative toxicity (EC20 mg kg-1) of the four metals was in the order of Sb (30) = Be (52)> Ba (370)> Mn (629). These results will be submitted to the Eco-SSL Work ou for review and inclusion in their database.

Available in PDF, EPUB and Kindle. Book excerpt: Mammalian Toxicology surveys chemical agents and examines how such chemicals impact on human health, emphasizing the importance in minimizing environmental exposure to chemical and physical hazards in our homes, communities and workplaces through such media as contaminated water, soil and air. Starting with the basic principles on a wide range of toxic agents, this textbook describes how they enter the body, their mechanisms of action once inside, and strategies for diagnosis, prevention and treatment. Topics covered include: General principles of toxicology: pharmacological and toxicological principles underpinning the study of toxicology, risk assessments and mechanisms of cell death Disposition: routes of chemical exposures, entry into the body and various tissues, storage, metabolic biotransformation and elimination, with examples from various toxicants. Toxic agents: the occurrences, disposition in the body, health effects, toxic mechanisms, antidotes and treatments of a range of agents including pesticides, metals, solvents, gases, nanomaterials, food components and additives, pharmaceuticals, drugs of abuse, natural toxins, endocrine disruptors, radiation, and warfare weapons. Toxic effects: including neurotoxicity, developmental toxicity, immunotoxicity, teratogenecity, male and female reproductive toxicity, mutagenecity, carcinogenicity, pulmonary toxicity, cardiovascular toxicity, hepatotoxicity, gastrointestinal toxicity and cardiovascular toxicity Toxicology and society: epidemiological studies of chemical-induced diseases in human populations, and a vision for toxicology in the 21st century. Mammalian Toxicology is an essential primer for students of toxicology, biochemistry, biology, medicine and chemistry. It is also appropriate for professional toxicologists in research or regulatory affairs, and anyone who needs to understand the adverse effects of toxic agents on the human body.

These two volumes bring together a vast amount of information on trace elements zinc and copper, magnesium, selenium, fluoride, cadmium, lead, and mercury. They will be of great value to physicians, nutritionists, and toxicologists. A particularly interesting section relates to the leaching of important trace metals by excess dietary fiber in some developing countries. These books are one of the important monograph series published by the American Nutrition Foundation.
Download or read book Soil Remediation written by and published by . This book was released on 2009 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil remediation deals with the removal of pollution or contaminants from environmental media such as soil and groundwater. This book presents new research the contamination of building materials with chemicals, which occurs as a result of storage, spills, and also catastrophic floods and hurricanes. Included in this book is an analysis and comparison of three protocols for the removal of chemicals trapped within building materials. The substantial economic consequences of heavy metal contamination in ecosystems, which poses major environmental problems world-wide, are presented as well. This book discusses the use of plants to remove or immobilise contaminants as a potentially safe and low cost method for the remediation of metal contaminated soil. Membrane techniques applied in water treatment from soil remediation are also reviewed and discussed with the aim to remove and/or recover metals and recycle water.

Book excerpt: To survive another generation, they'll need to live among the shifters. Long ago, a world war waged between shapeshifters and humans. Humans lost, and the consequences were dire…. Ella is part of a clan hidden deep in the forests of Washington State. She doesn't know if there are other human clans out there or if hers in the last one, but she knows there isn't a future for her people if they don't do something drastic. All of her life, she has heard horror stories about the Others, the beasts that surround them in high-tech dwellings beyond the mountains, but the Others may be their only hope. Ty Bearclaw, a grizzly shifter, is the curator at the Washington State Animal Sanctuary, Research, and Observation Center (WSASROC). A call from a rancher about something causing an unusual kind of havoc along the borders of the National Forest brings him to the Olympic Mountain National Park, where Ty is furious to discover that the rancher placed a trap to capture the creature on government-protected property. It isn't an animal caught in the trap, though—it's a human woman! Her entire species was believed to be extinct! What is even more confounding is his bear's reaction to the female. All his life he wondered who his mate would be, what she'd be like, what kind of shifter she would be. He never once considered that his mate might not be a shifter at all, and her very presence would change their understanding of the past and the future. A NY Times and USA Today bestselling author, the internationally acclaimed S.E. Smith presents a new story with her signature humor and unpredictable twists! Exciting adventure, hot romance, and iconic characters have won her a legion of fans. Over TWO MILLION books sold!
