Occurrence and fate of emerging pollutants of 17beta-estradiol and testosterone in hospital wastewater and effluent: The effect of activated sludge and chlorination processes
Introduction: In 2015, the European Union placed estrogen hormones on the list of compounds with a possible real risk to living organisms and emphasized the need for environmental research. The aim of this study was to determine the occurrence and effect of activated sludge process and chlorination on the fate of 17-beta estradiol and testosterone in hospital wastewater. Materials and Methods: ...
متن کاملDetection, Occurrence and Fate of Emerging Contaminants in Agricultural Environments.
A total of 79 papers published in 2016 were reviewed ranging from detailed descriptions of analytical methods, to fate and occurrence studies, to ecological effects and sampling techniques for a wide variety of emerging contaminants likely to occur in agricultural environments. New methods and studies on veterinary pharmaceuticals, steroids, antibiotic resistance genes, cyanotoxins, and potenti...
متن کاملFate and effects of triclosan in activated sludge.
Triclosan (TCS; 5-chloro-2-[2,4-dichloro-phenoxy]-phenol) is a widely used antimicrobial agent. To understand its fate during sewage treatment, the biodegradation and removal of TCS were determined in activated sludge. In addition, the effects of TCS on treatment processes were assessed. Fate was determined by examining the biodegradation and removal of TCS radiolabeled with 14C in the 2,4-dich...
متن کاملFate and effects of methylene chloride in activated sludge.
Activated sludge obtained from a municipal wastewater treatment plant was acclimated to methylene chloride at concentrations between 1 and 100 mg/liter by continuous exposure to the compound for 9 to 11 days. Acclimated cultures were shown to mineralize methylene chloride to carbon dioxide and chloride. Rates of methylene chloride degradation were 0.14, 2.3, and 7.4 mg of CH2Cl2 consumed per h ...
متن کاملGeneral Fate Model for Microconstituents in an Activated Sludge System.
Nine lab-scale continuous flow porous-pot bioreactors operating at various solids retention times and hydraulic retention times were conducted to simulate activated sludge (AS) systems and to evaluate the biodegradation kinetic models for the fate of 17α-ethinylestradiol (EE2), bisphenol-A (BPA), and triclosan (TCS) at the µg/L range. Mathematical models were applied to describe the degradation...
