TL;DR: The concentration of estrone increased along the treatment due to the partial oxidation of 17beta-estradiol in the aeration tank, and the overall removal efficiencies within the STP ranged between 70-90% for the fragrances, 40-65% forThe anti-inflammatories, around 65% for 17 beta-ESTradiol and 60% for sulfamethoxazole.

Removal of Pharmaceutical and Personal Care Products (PPCPs) under nitrifying and denitrifying conditions
TL;DR: Results indicated that fluoxetine (FLX), natural estrogens (E1+E2) and musk fragrances (HHCB, AHTN and ADBI) were transformed to a large extent under aerobic and anoxic conditions, whereas naproxen (NPX), ethinylestradiol (EE2), roxithromycin (ROX) and erythromycin(ERY) were only significantly transformed in the aerobic reactor.
Journal ArticleDOI
How are pharmaceutical and personal care products (PPCPs) removed from urban wastewaters
TL;DR: The presence of bioactive trace pollutants such as pharmaceuticals and ingredients of personal care products (PPCPs) in different environmental compartments (rivers, lakes, groundwaters, sediments, etc.) is an emerging issue due to the lack of existing information about the potential impact associated with their occurrence, fate and ecotoxicological effects.
Journal ArticleDOI
Fate of pharmaceutical and personal care products (PPCPs) during anaerobic digestion of sewage sludge.
TL;DR: Considering the difficulty of obtaining reliable PPCPs concentrations, especially those corresponding to the fractions sorbed onto sludge, a methodology to validate the experimental data has been developed and successfully applied and no influence of SRT and temperature on PPCP removal was observed.
Journal ArticleDOI
Rutin: A review on extraction, identification and purification methods, biological activities and approaches to enhance its bioavailability
TL;DR: The utilization of delivery systems for rutin or its enzymatic or chemical transformation towards highly soluble derivatives have the potential to improve r Rutin bioavailability, as well as its stability and/or specific biological properties.
