Paperback. Condición: New. Of the total number of consumer product chemicals the U.S. Environmental Protection Agency has identified, approximately 500 are considered high production volume (HPV) chemicals. This study investigated the occurrence and fate of high production volume household chemicals in wastewater systems. The study was initiated with a comprehensive review on HPV organic chemicals in household commodities and their contributions to municipal wastewater treatment systems. The comprehensive review presented the basis to compile a database on HPV chemicals and organic compounds in household commodities that have the potential to affect wastewater processes and effluent qualities. The occurrence of select HPV target compounds during wastewater treatment was studied by collecting composite samples of raw sewage and final treated effluents at seven full-scale treatment plants employing different operational conditions. Of the 26 household chemicals targeted in this study, 20 compounds were consistently detected in raw influents of full-scale wastewater treatment plants. Chemicals that are primarily used in products applied outdoors were generally not present in raw influent samples. The majority of compounds present in personal care and cleaning products generally appeared in all influent samples with concentrations of 2-phenoxyethanol (a preservative with various uses) and menthol (a fragrance with various uses) consistently exhibiting the highest concentrations of all compounds. The efficacy of advanced wastewater treatment processes to achieve removal and destruction of selected target compounds was studied through controlled lab- and pilot-scale studies (i.e., MBR, ozone, AOP). In general, biological treatment resulted in partial or complete removal (80%) indicating that biological treatment is a good treatment option for HPV household chemicals.

Buch. Condición: Neu. Neuware - The identification and quantification of the widespread occurrence of trace organic chemicals at minute concentrations in the aqueous environment impacted by human activities is a result of rapid advances in environmental analytical chemistry. The body of knowledge regarding the characterization, fate and transport of these chemicals of emerging concern (CECs) in the natural water environment and engineered water treatment processes, as well as their toxicity, hasgrown substantially over the last two decades. Recently, the focus in the environmental chemistry community has shifted from these CEC parent compounds to the fate, transport, and toxicity of transformation products, which are generated through abiotic and biotic mechanisms in natural systems andduring engineered advanced water treatment processes.This two-part book focuses on the studies and recent advancements towards the development of more harmonized strategies and workflows using non-target and suspects screening methods, including suitable bioassay approaches to assess the overall relevance of transformation products. Volume I covers the relevance of transformation products and international strategies to manage CECs, new methods for a comprehensive assessment of transformation products, and the fate and transport of transformationproducts in natural systems. This book is ideal for environmental scientists and engineers, particularly chemists, environmental engineers, public health officials, regulators, other chemistry-related professionals, and students.
