This book was released on 2013-02-11 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomonitoring of water quality is very much essential for assessing the overall health of water bodies and safe supply of drinking water. The chemical nature of toxicant is highly dynamic in environment with time and space whereas biological system can integrate all environmental variables over a large period of time in terms of effect that can be easily measured and quantified. In view of the above, there is a pressing need to determine the water quality of natural resources as well as drinking water based on the standard protocols and guidelines from regulatory agencies. It is clear that the synthetic chemicals are essential for our society to maintain the health and well being of the people. However, there has been a range of detrimental effects on human health and natural environment. In general, we need to improve our management of waste chemicals discharged into the air, water and soil environments. New techniques are needed to predict adverse effects before they occur and for the treatment of wastes. In addition, a range of social, political and economic factors will be needed to be taken into account in order to achieve success.

Download or read book Monitoring of Water Quality written by F. Colin and published by Elsevier. This book was released on 1998-07-21 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water can be considered as one of the basic elements supporting life and the natural environment, a primary component for industry, a consumer item for humans and animals and a vector for domestic and industrial pollution. Various European Directives already provide a framework for the control of aquatic substances, the quality of bathing, surface and drinking water and effluent control. Such regulatory measures are closely related to analytical measurements. In order to comply with these regulations on a permanent basis, treatment plants and distribution companies, as well as water users and polluters, need to implement automated measuring techniques, such as sensors and other analytical tools in continuous or sequential mode to obtain suitable alarm systems and facilitate the management of water resources and decision making processes. This approach is in continuous evolution within the European Union. In view of the consequences of wrong measurements, it is vital that reliable quality control systems be achieved and maintained. At present, only a small range of analytical parameters can be measured automatically, it is therefore necessary to develop and validate new methods to extend the list of parameters. The development of new methodologies requires that the most recent know-how in fields such as optics, electrochemistry, biochemistry, chemometrics and others be shared by experts. In order to identify possible actions to be undertaken in the field of standards, measurements and testing for monitoring water quality, the Standards Measurements and Testing (SMT) Programme of the European Union, organised a European workshop that was held in Nancy 29-31 May 1997. This workshop bought together researchers and industrial users with the aim to make an overview of the present state-of-the-art, to consider possible improvements in existing techniques and the need and possibilities of developing new advanced technologies.

This book was released on 1993 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quarterly biomonitoring tests were performed for one year on composite effluent samples taken-from the Ft. Detrick (Frederick, MD) wastewater treatment plant. The cladoceran (Ceriodaphnia dubia) and fathead minnow (Pimephales promelas) acute 48-h LC50 tests were used to evaluate the toxicity of the effluent for two quarters. The cladoceran 7-d survival and reproduction test and the fathead minnow 7-d survival and growth tests were used for two quarters. The effluent was not toxic to the cladoceran or fathead minnow when tested in both acute and chronic bioassays. One priority pollutant analysis was conducted on a composite effluent sample. The analysis showed that four (Cu, Pb, Ni, and Zn) of 12 heavy metal priority pollutants were present in the effluent. The concentrations of the four heavy metals, with the exception of lead for chronic exposure, were below the U.S. EPA numerical water quality criteria for acute and chronic toxicity of the metals to freshwater organisms. The freshwater chronic criteria value for lead is 3.2 ug/L; 6 ug/L were found in the effluent sample. Two volatile organics (bromodichloromethane and dibromochloromethane) were also detected. Both halomethanes were well below the U.S. EPA numerical water quality criteria for acute toxicity to freshwater organisms; no Biomonitoring, Bioassays, Priority pollutants, Acute toxicity, Chronic toxicity, Cladoceran, Ceriodaphnia dubia, Fathead minnow, Pimephales promelas, Wastewater treatment plant, WWTP. criterion is available for chronic exposure to halomethanes.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent developments in advanced biological treatment technologies that are attracting increasing attention or that have a high potential for large-scale application in the near future. It also explores the fundamental principles as well as the applicability of the engineered bioreactors in detail. It describes two of the emerging technologies: membrane bioreactors (MBR) and moving bed biofilm reactors (MBBR), both of which are finding increasing application worldwide thanks to their compactness and high efficiency. It also includes a chapter dedicated to aerobic granular sludge (AGS) technology, and discusses the main features and applications of this promising process, which can simultaneously remove organic matter, nitrogen and phosphorus and is considered a breakthrough in biological wastewater treatment. Given the importance of removing nitrogen compounds from wastewater, the latest advances in this area, including new processes for nitrogen removal (e.g. Anammox), are also reviewed. Developments in molecular biology techniques over the last twenty years provide insights into the complex microbial diversity found in biological treatment systems. The final chapter discusses these techniques in detail and presents the state-of-the-art in this field and the opportunities these techniques offer to improve process performance.

Download or read book Impacts of Biomonitoring Requirements on DoD Wastewater Treatment Facilities written by and published by . This book was released on 1991 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legislative emphasis on reducing the toxicity of wastewater effluent has resulted in increasingly sophisticated methods of determining toxicity. The purpose of this research project is to assess the impacts on DoD wastewater treatment facilities of one new monitoring method, biomonitoring. Biomonitoring has impacted DoD wastewater treatment facilities, however not to the degree anticipated. For bases that have been impacted, cost of contracting the tests is the primary problem associated with biomonitoring. Many bases have not been impacted because wastewater reuse has negated the need for discharge permits, and the inherent monitoring requirements. Bases subject to biomonitoring should assess water reuse as a means of wastewater disposal. Additionally, other bases have not as yet had biomonitoring requirements imposed on them. It is recommended that these bases prepare for future biomonitoring requirements by having their effluent tested to determine toxicity in anticipation of biomonitoring implementation by the states.

This book was released on 1996 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Old 0-Field is a hazardous waste disposal site at the Aberdeen Proving Ground-Edgewood Area, Aberdeen, Maryland, which has contaminated the underlying groundwater. The contaminated groundwater is collected and treated at the Old 0-Field Groundwater Treatment Facility (GwTF) with subsequent discharge to the Gunpowder River. An in-line automated fish ventilatory biomonitoring system was installed at the GWTF to monitor the effluent for unexpected toxicity as it is discharged. A number of out of control events (stressed fish) occurred during the study (June 23, 1995 to March 31, 1996). The total number of days the system obtained out of control responses was 21.0 d. Explanations for the out of control responses were available for 20.6 d. No obvious explanations were apparent for 0.5 d. The out of control responses occurred from (1) changes in effluent water quality; (2) power failures; or (3) a proportional diluter failure. Changes in effluent water quality accounted for 89.2% of the total out of control responses with explanation. Loss of power and a diluter malfunction accounted for 5.9% and 4.9% of the out of control responses with explanation, respectively. Out of control responses with no explanation occurred 0.2% of the time or 0.5 d during the study. No acute toxicity attributable to the GWTF effluent quality occurred during the study.

Download or read book Human Biomonitoring for Environmental Chemicals written by National Research Council and published by National Academies Press. This book was released on 2006-11-30 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomonitoring—a method for measuring amounts of toxic chemicals in human tissues—is a valuable tool for studying potentially harmful environmental chemicals. Biomonitoring data have been used to confirm exposures to chemicals and validate public health policies. For example, population biomonitoring data showing high blood lead concentrations resulted in the U.S. Environmental Protection Agency's (EPA's) regulatory reduction of lead in gasoline; biomonitoring data confirmed a resultant drop in blood lead concentrations. Despite recent advances, the science needed to understand the implications of the biomonitoring data for human health is still in its nascent stages. Use of the data also raises communication and ethical challenges. In response to a congressional request, EPA asked the National Research Council to address those challenges in an independent study. Human Biomonitoring for Environmental Chemicals provides a framework for improving the use of biomonitoring data including developing and using biomarkers (measures of exposure), research to improve the interpretation of data, ways to communicate findings to the public, and a review of ethical issues.
