Monitoring release of pharmaceutical compounds: Occurrence and environmental risk assessment of two WWTP effluents and their receiving bodies in the Po Valley, Italy

Efficient degradation of sulfamethoxazole by the Fe(II)/HSO5− process enhanced by hydroxylamine: Efficiency and mechanism

“…Therefore, the objective of this study is to investigate the efficiency and mechanism of the HA/Fe(II)/PMS process in eliminating typical antibiotics. Sulfamethoxazole (SMX), one of the most widely used sulfonamide antibiotics to treat human and veterinary diseases as well as to promote the growth of food animals, was selected due to its frequent detection in the aquatic environment (Al Aukidy et al, 2012). The study is specifically focused on, (i) the degradation efficiency of SMX; (ii) the role of HA; (iii) the role of the reactive species involved; (iv) the identification of degradation products and possible transformation pathways in the HA/Fe(II)/PMS process, and (v) the treatment efficiency of SMX from the real pharmaceutical wastewater by the process.…”

Evaluation of enhanced coagulation coupled with magnetic ion exchange (MIEX) in natural organic matter and sulfamethoxazole removals: The role of Al-based coagulant characteristic

“…Table 1 lists the Al species distributions of three coagulants. It could be found that, AS and Al 13 are mainly composed of monomeric species (Al a ) and medium polymer species (Al b ), respectively; while all the Al a , Al b and Al c species (sol or gel Al(OH) 3 ) could be detected in the PACl solution.…”

“…NOMs lead to disinfection byproduct (DBPs) by reacting with common disinfectants (e.g., chlorine, ozone, chlorine dioxide, chloramines) [1]. Certain SOCs, encompassing pharmaceuticals and personal care products (PPCPs), pesticides, household chemicals and endocrine disrupting chemicals, have been shown to impose adverse impacts on human, wildlife and aquatic ecosystems [2,3]. Organic contaminants have become an increasing cause of concern for governments and water authorities around the world as they attempt to implement sustainable water treatment practices.…”

Screening of pharmaceuticals and illicit drugs in wastewater and surface waters of Spain and Italy by high resolution mass spectrometry using UHPLC-QTOF MS and LC-LTQ-Orbitrap MS

“…To ensure national significance, compounds found from previous studies of these regions were investigated and added to the database (Spain (Gracia-Lor et al, 2011 ; Italy (Al Aukidy et al, 2012;Zuccato et al, 2010Zuccato et al, , 2006). In total, 107 PIDs and 220 fragment ions were incorporated in the database (See ESM Table S1).…”
