The safety of the nation's drinking water must be maintained to ensure the health of the public. The U.S. Environmental Protection Agency (EPA) is responsible for regulating the levels of substances in the drinking water supply. Copper can leach into drinking water from the pipes in the distribution system, and the allowable levels are regulated by the EPA. The regulation of copper, however, is complicated by the fact that it is both necessary to the normal functioning of the body and toxic to the body at too high a level. The National Research Council was requested to form a committee to review the scientific validity of the EPA's maximum contaminant level goal for copper in drinking water. Copper in Drinking Water outlines the findings of the committee's review. The book provides a review of the toxicity of copper as well as a discussion of the essential nature of this metal. The risks posed by both short-term and long-term exposure to copper are characterized, and the implications for public health are discussed. This book is a valuable reference for individuals involved in the regulation of water supplies and individuals interested in issues surrounding this metal.
The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logi...
Raising Lazarus is Dr. Robert Pensack's personal memoir of his battle to maintain his sanity in the face of extraordinary suffering. Dr. Pensack's story chronicles his near life-long struggle with a mortal illness, Hypertrophic Cardiomyopathy, or HCM (formally known as IHSS), a genetic illness marked by abnormality of the heart muscle. After the disease claimed the life of his young mother, the adolescent Pensack--and his brother Richard, who also suffered from HCM--went on to become chronic-research heart patients at The National Institutes of Health in Bethesda, Maryland. They endured a litany of surgeries and multiple near-death experiences caused by cardiac arrests until, thirty years la...
Breaking a 200-year impasse on the origins of the gospels Biblical scholars want to get to the roots of the gospels—the very earliest memories of Jesus and his world. Though scholars know about all the major concepts at work—Q, the Urgospel, priority—it seems like a definitive solution to the Synoptic problem is hopelessly unattainable. Why the impasse? And where do we go from here? In Jesus Tradition, Early Christian Memory, and Gospel Writing, Alan Kirk guides us through the history of biblical scholars’ quest for the authentic source. Kirk reveals that outdated assumptions about ancient media realities have caused the past two centuries of academic deadlock. Using cutting-edge scholarship on orality, memory, and tradition formation, he shows how the origins of the gospels may be found in the memory practices of the earliest Jesus communities. Jesus Tradition, Early Christian Memory, and Gospel Writing is an essential resource for scholars and students looking to better understand this complex and rapidly changing field.
Nineteen twisted tales from a vibrant, online community of horror enthusiasts! What’s HorrorTube? A creepy, new carnival ride combining a water slide park with a haunted funhouse? Not quite, although that sounds like a blast. A subset of BookTube, HorrorTube is an online community of horror enthusiasts who regularly post YouTube videos about horror-related topics, including books, films, and fiction writing. Some of the writers included in this anthology cover horror exclusively. You’ll find them posting creepy photos on Instagram or waxing poetic about the seventies drive-in flick that kept them up all night. Some read widely, only delving into the horror genre occasionally. All are pas...
