Abstract:

Metals, such as copper, zinc, cadmium, nickel and lead, can vary significantly in concentration over time and across small specified areas at the micro scale (geographic regions), either naturally or also due to human activities, such as urbanization, industrial and agricultural activities. Their chemical forms and distribution control their mobility, bioavailability and subsequent potential for toxicity which, in turn, dictates surface water quality. The physicochemical forms in which a metal ion is present (i.e. its speciation) determine the behaviour of the metal and therefore its bioavaila

An enthusiastic global campaign on intervention in water in the Lower Income Countries (LICs) was launched by the UN at the International Conference on Water and the Environment (ICEW), in Rio de Janerio, in January of 1992. In June of the same year, in Dublin, a plan of action was devised and a commitment to the water related goals highlighted in Rio de Janerio was made. Close to fifteen years on, there is little to show by way of success in the intended countries. Over 1.1 billion people in the LICs lack safe water. The direct impact of this is a higher risk of waterborne diseases. The water

Abstract:

This research is motivated by an issue frequently encountered in environmental water quality evaluation. Many times, the sample size of water monitoring data is too small to have adequate power. Here, we present a Bayesian power prior approach by incorporating the current data and historical data and/or the data collected at neighboring stations to make stronger statistical inferences on the parameters of interest. The elicitation of power prior distributions is based on the availability of historical data, and is realized by raising the likelihood function of the historical data to a fractio

Abstract:

Implementation of the Clean Water Act requires agencies to monitor aquatic sites on a regular basis and evaluate the quality of these sites. Sites are evaluated individually even though there may be numerous sites within a watershed. In some cases, sampling frequency is inadequate and the evaluation of site quality may have low reliability. This dissertation evaluates testing procedures for determination of site quality based on modelbased procedures that allow for other sites to contribute information to the data from the test site. Test procedures are described for situations that involv

Abstract:

The chemical speciation of trace metals controls their potential bioavailability and therefore toxicity to exposed organisms. Despite previous studies demonstrating the ameliorative effects of dissolved organic carbon (DOC) on metal toxicity, the effectiveness of ligands from varying sources and of potentially variable composition in controlling speciation has not been studied in detail in estuarine waters. In addition, the effect of DOC on radionuclide contaminants in combination with trace metals has not been investigated in any waters. This is of particular interest in the estuarine environ

Direktivet är rättsligt bindande för medlemsstaterna och har målet att samtliga vattenförekomster i EU ska nå minst god status. I arbetet med vattenförvaltningen används begreppen statusklassificering, som är ett mått på rådande vattenkvalitet i vattenförekomsten, och miljökvalitetsnormer, som den vattenkvaliteten vattenförekomsten ska ha vid en viss tidpunkt. Statusklassificeringen består av ekologisk och kemisk status. Ekologisk status bedöms utifrån kvalitetsfaktorer (exempelvis växtplan

Abstract:

The present study was undertaken to assess water quality of Siliserh Lake in Alwar during the month of March 2018, and to assess its suitability for drinking, irrigation, and industrial usages using various indices. The suitability for drinking and irrigation were determined by comparing the obtained mean value with the BIS standards and prescribed indices. The water of the lake was found to be suitable for drinking for all the parameters, as all the parameters have their average value below the prescribed BIS standard. Slightly raised values were observed near Kishanpura and Ringaspura villag
