Integrated Urban Water Resources Management
Growing populations and rising standards of living exert stress on water supply and the quality of drinking water. In wastewater management, new challenges are caused by new chemicals of concern, including endocrine disrupters, pharmaceuticals, hormones, and personal care products, which often pass through wastewater treatment plants unabated, but may cause serious impacts on receiving aquatic ecosystems. Advanced wastewater treatment leads to production of biosolids, which are processed in various ways, including on-land applications in agriculture. Municipal effluents, combined with increasing withdrawals of water, lead to the worsening of receiving water quality. Expert opinions indicate that the only way to deal with the current urban water management dilemmas is by integrated management and innovative delivery of water services. This book presents important aspects of Challenges in Management of Urban Water Resources, Challenges in Urban Water Supply, Urban Drainage and Water Bodies, Wastewater Treatment and Security, and Wastewater Treatment and Reuse.
Environmental Chemistry : Green Chemistry and Pollutants in Ecosystems
Environmental chemistry is a new, fast developing science aimed at deciphering fundamental mechanisms ruling the behaviour of pollutants in ecosystems. Applying this knowledge to current environmental issues leads to the remediation of environmental media, and to new, low energy, low emission, sustainable processes. This book describes the state-of-the-art advances regarding the pollution of water, soils, atmosphere, food and living organisms by toxic metals, fossil fuels, pesticides and other organic pollutants. Furthermore, the eco-toxicology section presents novel bio-assays to assess the toxicity of various pollutants such as dioxins and endocrine disrupters within complex media. The green chemistry section highlights novel chemical reactions based upon environmentally friendly conditions. The analytical chemistry section describes very sensitive methods which trace the fate of pollutants in complex ecosystems.
Congenital Diseases and the Environment
"In recent years, increasing attention and resources have been brought to bear on the relationship between the environment and congenital diseases. These diseases were previously thought to be mostly due to genetic causes. Even though the importance of genes as factors in causation is accepted, environmental factors seem to be implicated just as strongly. This book explores some further concepts that have arisen from more recent perceptions of environmental effects and their possible interactions with living systems. Discussion and presentation of old and novel ideas is targeted at developing a more holistic and united perception of the interaction between congenital diseases and the environment. Amongst the topics discussed are: -effects of prenatal exposure to toxic chemicals -intra-uterine exposure to drugs -effects of endocrine disrupters -environmental risk and sex ratio in newborns -surveillance of environmental impact-research and policy."
Bioremediation of Soils Contaminated with Aromatic Compounds
Environmental biotechnology, which was in its infancy in the early 80's, has evolved thanks to the revolution brought about by molecular biology. Multiple successes in the biological cleanup of civil and industrial wastewater and of hydrocarbon soil pollution, demonstrate the vast power of clean technologies. In addition, the buildup of information on the activities of microorganisms as catalysts in all sorts of natural, industrial and animal environments has flourished. There is a continuing realization of the critical role of microbial processes in biological, industrial and geological systems. Since environmental biotechnology has matured, it is ready to tackle bigger challenges: the scaling up of many bioremediation systems still in progress, the search for novel biocatalysts for industrial applications, the continuing effort against common human life-threatening processes such as antibiotic resistance, the accumulation of hormone-mimicking substances (endocrine disrupters), the deposition of air-borne pesticides in the environment and, the degradation of recalcitrant contaminants. These endeavors will help prevent the contamination of food chains, protect human life and allow for human activity and economic development that do not compromise environmental sustainabijity.
