Available in PDF, EPUB and Kindle. Book excerpt: Water covers about two-thirds of the surface of earth, but only 0.627 percent of this water is the sweet surface and subsurface water available for the survival of freshwater organisms including man (1,2). Some of this fresh or sweet water lies in practically uninhabitable regions (rivers: }1ackenzie in Canada; Amazon in Central America; Ob, Yenesey, and Lenta in Siberia, etc.). Also, most of the major rivers (the Mississippi in U.S.A., the Rhine in Europe, the Volga in U.S.S.R., the Ganges in India, etc.), because they flow through agricultural land or urban and industrial areas, have become highly contaminated with chemicals (3). This leaves us with shrinking resources of sweet surface water. In the United States, the dependable supplies of this water are already dwindling in cities like New York and Los Angeles and states like New Mexico and Texas (3).
Book Synopsis Advanced Oxidation Processes (AOPs) in Water and Wastewater Treatment by : Aziz, Hamidi Abdul
Download or read book Advanced Oxidation Processes (AOPs) in Water and Wastewater Treatment written by Aziz, Hamidi Abdul and published by IGI Global. This book was released on 2018-08-03 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population growth and industrial development have increased the amount of wastewater generated by urban areas, and one of the major problems facing industrialized nations is the contamination of the environment by hazardous chemicals. Therefore, to meet the standards, suitable treatment alternatives should be established. Advanced Oxidation Processes (AOPs) in Water and Wastewater Treatment is a pivotal reference source that provides vital research on the current, green, and advanced technologies for wastewater treatment. While highlighting topics such as groundwater treatment, environmental legislation, and oxidation processes, this publication explores the contamination of environments by hazardous chemicals as well as the methods of decontamination and the reduction of negative effects on the environment. This book is a vital reference source for environmental engineers, waste authorities, solid waste management companies, landfill operators, legislators, environmentalists, and academicians seeking current research on achieving sustainable management for wastewater treatment.

Book Synopsis Chemical Contaminants in Canadian Aquatic Ecosystems by : D. M. Whittle
Download or read book Chemical Contaminants in Canadian Aquatic Ecosystems written by D. M. Whittle and published by Canadian Government Publishing. This book was released on 1998 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on those chemicals that persist in the Canadian environment and that are accumulated by aquatic organisms. It summarizes scientific information collected previously, with emphasis on Canadian research findings published in the last decade. The first part of the report introduces the general features of aquatic ecosystems and provides basic information on the fate and effects of chemical contaminants. The second part reviews contaminant related issues for the following geographic areas: Atlantic marine ecosystems including the St. Lawrence, Bay of Fundy, and general north-west Atlantic; freshwater ecosystems including the Great Lakes and inland waters; the Arctic marine ecosystem; and Pacific aquatic ecosystems including the British Columbia coastal ecosystem, the open coast, and some of the major rivers. All chapters discuss the major contaminant issues, important oceanographic or limnological features, biological resources, and sources of contaminants as well as contaminant trends, distribution, and effects. Current and emerging chemical contaminant issues and associated research topics are summarized at the end of each chapter. The third part is an overall assessment of current knowledge of chemical contaminants and their effects on fish and fish habitat, and identifies major current and emerging contaminant issues confronting Canada's fish and fish habitat.
Book Synopsis Currently Used Pesticides and Their Mixtures by : Eliška Rozmankova

Available in PDF, EPUB and Kindle. Book excerpt: Pesticides have enabled humankind to protect its crops from pests, intensifying thus the crop yields to sustain the growing population. However, pesticides often end up in aquatic water bodies, e.g. via field runoff, where they may harm non-target organisms. The environmental concentrations of pesticides are often considered safe for aquatic ecosystems although they might induce sublethal changes in exposed organisms. Moreover, the organisms are generally not dealing with only one pesticide issued from a nearby field but with a complex mixture of various chemical compounds, interacting amongst themselves, and creating a toxic cocktail with unknown and hardly predictable impacts. These compounds, each with different environmental fate, eventually degrade and form more or less toxic and persistent metabolites aggravating the complexity of the mixtures.This dissertation thesis summarizes the state-of-the-art in pesticide mixture toxicity research and is composed of five research articles dealing with sublethal effects of selected pesticides on non-target aquatic species. Vulnerable embryo-larval stages of two model organisms: freshwater zebrafish (Danio rerio) and euryhaline bivalve Pacific oyster (Magallana gigas) were used to assess the sublethal toxicity of especially environmental concentrations (detected in selected European water bodies) of commonly used herbicide S metolachlor with its two metabolites metolachlor oxanilic acid and metolachlor ethanesulfonic acid, insecticide imidacloprid, and fungicide propiconazole, alone and in a mixture. A complementary in situ approach was carried out to evaluate a real impact on early-life stages of the Pacific oyster in Arcachon Bay in France, a final recipient of various substances including pesticides from respective watersheds.First, zebrafish embryo-larval stages were observed to be highly sensitive to environmentally relevant concentrations of propiconazole and to a lesser extent also to imidacloprid. In contrast, S-metolachlor and its metabolites had almost no effect on their development, neurobehavioral functions, or gene expression except for altered genes implicated in the thyroid system. A mixture of these compounds exhibited a concentration addition effect on zebrafish development. These observations imply that the development of freshwater fish may be at risk with current agricultural practice.Second, a study with Pacific oyster embryos and larvae revealed very low toxicity of propiconazole and imidacloprid on their development and locomotion patterns. Few effects caused by these compounds were observed at the molecular level, as well as the effects caused by the mixture. The environmental concentration of the mixture induced developmental malformations in oyster larvae, however, those exposed in situ in Arcachon Bay did not show higher proportions of abnormal larvae suggesting that the water quality of Arcachon Bay is sufficient for oyster development. Nevertheless, oyster larvae exposed in the inner part of Arcachon Bay showed different gene expression levels than larvae from the reference site located near the ocean entrance, which may indicate consequences of a potential long term impact.These results documented that embryo-larval stages of zebrafish and Pacific oysters are relevant tools for the assessment of low concentrations of pesticides and pesticides in a mixture, and that laboratory studies complemented with field research are useful for (eco)toxicity assessment and of high ecological relevance.
