This book was released on 1988 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of the acute and chronic toxicity of effluent samples from the Patapsco Wastewater Treatment Plant (WWTP), Baltimore, Maryland, was performed approximately twice weekly from April 1986 to January 1987. Acute toxicity of both the primary and secondary effluents was evaluated using Ceriodaphnia dubia, Mysidopsis bahia, and Microtox [a luminescent marine bacteria Photobacterium phosphoreum (Beckman Instruments, Inc.)]; chronic toxicity was evaluated using the C. dubia seven-day chronic test. The data indicate that C. dubia was the most sensitive indicator of acute toxicity for both primary and secondary effluent wastewaters. The acute responses for M. bahia and Microtox were considerably less sensitive than those for C. dubia. The 48-h median lethal concentration (LC50) values for C. dubia ranged from 0.5 to 23.4% secondary effluent and 0.1 to 6.5% primary effluent wastewaters. Microtox 5-min median effective concentration (EC50) values ranged from 9.4 to 100% secondary effluent and 0.6 to 19.5% primary effluent, respectively. M. bahia 96-h LC50 values were 8.9 to 100% secondary effluent and 14.8 to 35.4% primary effluent, respectively. The seven-day C. dubia chronic values (ChV) for the primary and secondary effluents were only slightly lower than the acute responses, ranging from
Book Synopsis Acute and Chronic Toxicity to the Fathead Minnow, Pimephales Promelas, of Effluents from a Treatment Plant Receiving Dye and Pigment Processing Wastewater by : KA. Dostal
Download or read book Acute and Chronic Toxicity to the Fathead Minnow, Pimephales Promelas, of Effluents from a Treatment Plant Receiving Dye and Pigment Processing Wastewater written by KA. Dostal and published by . This book was released on 1985 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ninety-six hour, static acute, and continuous-flow early life-stage (ELS) chronic toxicity tests, using the fathead minnow (Pimephales promelas), were conducted to evaluate the toxicity of effluents from a pilot scale activated sludge (AS) treatment system receiving dye and pigment wastewater. In the first test with a powdered activated carbon (PAC) dosage of 1800 mg/L of influent, survival was the most sensitive measure of effect in the ELS test. The highest effluent concentration tested (10%) was lethal to the embryos and larvae. No adverse effect on survival or growth was observed at lower effluent concentrations (5.0 to 0.63%). The maximum acceptable toxicant (effluent) concentration (MATC) was between 10 and 5%. Ten 96-h median lethal concentration (LC50) values from static acute tests ranged from 12.9 to greater than 80%. In the second test at a PAC dosage of 1000 mg/L of influent, growth was the most sensitive measure of effect in the ELS test. Larval growth was significantly reduced at the highest effluent concentration tested (20%). The MATC was between 20 and 10%. Seven 96-h LC50s from static acute tests ranged from 28.3 to greater than 80%. The effluent from the treatment system receiving the higher PAC dosage of 1800 mg/L was more toxic than the effluent from the treatment system receiving the lower PAC dosage of 1000 mg/L. However, the influent to the treatment system receiving the higher level of PAC also was more acutely toxic.

Available in PDF, EPUB and Kindle. Book excerpt: Frontiers in Urban Water Management presents the state-of-the art in urban water management at the beginning of the 21st century. The book marks the end of the fifth phase of UNESCO's International Hydrological Programme in this field by bringing together major scientific and professional players to address critical and topical issues in water management. This team of leading world experts investigate themes such as the challenges of urban water management, infrastructure integration issues, and emerging paradigms in water supply and sanitation. Key issues are investigated from the hydrological, technical and managerial points of view, incorporating both social and economic realities. Specific reference is also made to solutions for developing countries. With a view to the future, conclusions from past experiences are highlighted, new pathways are explored and future developments are suggested. Contents The challenge of urban water management Urban water as a part of integrated catchment management Interactions with the environment Infrastructure integration issues Emerging paradigms in water supply and sanitation Problems of developing countries Economic and financial aspects Social, institutional and regulatory issues Outlook for the 21st Century
