Constructed Wetlands for Wastewater Treatment

Author: Donald A. Hammer
Publisher: CRC Press
ISBN: 1000114872
Category : Technology & Engineering
Languages : en
Pages : 856

Book Description
Both practical and theoretical, this book provides the basic principles of soil chemistry, hydrology, wetland ecology, microbiology, vegetation and wildlife as a sound introduction to this innovative technology to treat toxic wastewaters and sludges. The use of wetlands for acid mine drainage, and metals removal in municipal, urban runoff, and industrial systems is discussed. Case histories are also presented, demonstrating specific types of constructed wetlands and applications to municipal wastewater, home sites, coal and non-coal mining, coal-fired electric power plants, chemical and pulp industry, agriculture, landfill leachate, and urban stormwater. Construction and management guidelines are clearly explained, providing information on applicable policies and regulations, siting and construction, and operations and monitoring of constructed wetlands treatment systems. Recent theoretical and empirical results from operating systems and research facilities, including such new applications as nutrient removal from eutrophic lakes and urban stormwater treatment within highway rights-of-way, are included. This book is an ideal resource for wastewater treatment plants, consulting engineers, federal and state regulators, industrial environmental managers, municipalities, environmental health professionals, and ecologists.

Interconnections Between Human and Ecosystem Health

Book Description
Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to humans, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older.

Seafood Safety

Languages : en
Pages : 449

Book Description
Can Americans continue to add more seafood to their diets without fear of illness or even death? Seafood-caused health problems are not widespread, but consumers are at risk from seafood-borne microbes and toxinsâ€"with consequences that can range from mild enteritis to fatal illness. At a time when legislators and consumer groups are seeking a sound regulatory approach, Seafood Safety presents a comprehensive set of practical recommendations for ensuring the safety of the seafood supply. This volume presents the first-ever overview of the field, covering seafood consumption patterns, where and how seafood contamination occurs, and the effectiveness of regulation. A wealth of technical information is presented on the sources of contaminationâ€"microbes, natural toxins, and chemical pollutantsâ€"and their effects on human health. The volume evaluates methods used for risk assessment and inspection sampling.

Dioxin Assessment in a River Flood Plain

Book Description
Dioxins are a group of 210 chemicals with similar properties and structures that are usually found as a "mixture" in the environment. Dioxins are found at low levels in air, soil, water, and sediment as well in foods such meat, dairy, fish, and shellfish. The highest levels are usually found in sediments soil and animal fats. The most toxic chemical in the group is 2,3,7,8-tetrachlorodibenzo-para-dioxin, which is the "standard" to which other dioxins are compared. This paper examines the Michigan Department of Environmental Quality (MDEQ) assessment and remediation efforts in the Tittabawassee River (Michigan, USA) flood plain. Soil and sediment samples indicate higher than "normal" (background) levels of dioxins for soil and sediment, which exceed the Center for Disease Control (CDC) and U.S. Agency for Toxic Substances and Diseases Registry (ATSDR) action level of 1000 parts per trillion. Data presented indicates the difficulties associated with assessing historical dioxin levels in environments such as soil and sediments. Activities associated with these efforts such as dioxin and furan exposure studies, animal toxicology assessments, U.S. Environmental Protection Agency (EPA) enforcement, MDEQ efforts to expedite remediation, as well as future directions for this on-going project are discussed.
