Spatial differences and temporal changes in illicit drug use in Europe quantified by wastewater analysis
(2014)
Aims To perform wastewater analyses to assess spatial differences and temporal changes of illicit drug use in a large European population. Design Analyses of raw wastewater over a 1-week period in 2012 and 2013. Setting ...
Kinetic and mechanism investigation on the photochemical degradation of atrazine with activated H2O2, S2O82− and HSO5−
(2014)
•Degradation of atrazine was investigated in UV, UV/H2O2, UV/HSO5− and UV/S2O82− AOPs.•UV/S2O82− process was found to be more efficient as well as more economical.•The pH affected UV/S2O82− but had no significant influence ...
Reduction of clarithromycin and sulfamethoxazole-resistant Enterococcus by pilot-scale solar-driven Fenton oxidation
(2014)
The presence of pathogenic antibiotic-resistant bacteria in aquatic environments has become a health threat in the last few years. Their presence has increased due to the presence of antibiotics in wastewater effluents, ...
Utilizing solar energy for the purification of olive mill wastewater using a pilot-scale photocatalytic reactor after coagulation-flocculation
(2014)
This study investigated the application of a solar-driven advanced oxidation process (solar Fenton) combined with previous coagulation/flocculation, for the treatment of olive mill wastewater (OMW) at a pilot scale. ...
Proposed transformation pathway and evolution profile of diclofenac and ibuprofen transformation products during (sono)photocatalysis
(2014)
Liquid chromatography time-of-flight mass spectrometry (UPLC/ESI–QToF–MS) was used for the elucidation of the main transformation products (TPs) resulting from the degradation of diclofenac (DCF) and ibuprofen (IBP) during ...
Degradation kinetics and mechanism of β-lactam antibiotics by the activation of H2O2 and Na2S2O8 under UV-254nm irradiation
(2014)
The extensive production and usage of antibiotics have led to an increasing occurrence of antibiotic residuals in various aquatic compartments, presenting a significant threat to both ecosystem and human health. This study ...
Environmental side effects of pharmaceutical cocktails: what we know and what we should know
(2014)
Cocktails of pharmaceuticals are released in the environment after human consumption and due to the incomplete removal at the wastewater treatment plants. Pharmaceuticals are considered as contaminants of emerging concern ...
Impact assessment of the reuse of two discrete treated wastewaters for the irrigation of tomato crop on the soil geochemical properties, fruit safety and crop productivity
(2014)
•Treated wastewater from two tertiary treatment technologies was applied for irrigation.•Wastewater irrigation did not significantly impact soil heavy metal content.•Heavy metals in tomato fruits were within the safe limits ...
