Towards universal wavelength-specific photodegradation rate constants for methyl mercury in humic waters, exemplified by a Boreal lake-wetland gradient.
Cristal Fernández-Gómez,Andreas Drott,Erik Björn,Sergi Díez,Josep M. Bayona,Solomon Tesfalidet,Anders V. Lindfors,Ulf Skyllberg +7 more
TL;DR: If the photon fluxes of PAR, UVA, and UVB radiation are separately determined and the wavelength-specific light attenuation is corrected for, the first-order rate constants kpdPAR, kpdUVA and kpdUVB will be universal to waters in which DOM controls the formation of ROS, and the chemical speciation of MeHg is controlled by the complexation with DOM associated thiols.

Impact of water saturation level on arsenic and metal mobility in the Fe-amended soil
Jurate Kumpiene,Daniel Ragnvaldsson,Lars Lövgren,Solomon Tesfalidet,Björn Gustavsson,Anders Lättström,Per Leffler,Christian Maurice +7 more
TL;DR: The batch leaching test used for waste characterization substantially underestimated As solubility that could occur under water-saturated (anaerobic) conditions, and other techniques than Fe-stabilization of As containing soil should be considered.

Desalination by direct contact membrane distillation using mixed matrix electrospun nanofibrous membranes with carbon-based nanofillers: A strategic improvement
M. Essalhi,M. Essalhi,Mohamed Khayet,Mohamed Khayet,Solomon Tesfalidet,Mohammed Alsultan,Naser Tavajohi +6 more
TL;DR: In this article, a mixture of hydrophobic and super-hydrophobic mixed matrix electrospun nanofibrous membranes (MM-ENMs) were used for direct contact membrane distillation.

Determination of melamine in milk powder using zwitterionic HILIC stationary phase with UV detection.
TL;DR: A hydrophilic interaction liquid chromatography-UV method was developed for the determination of melamine in milk powder and is sensitive and cost effective, therefore, suitable for screening of melamines in tainted milk products.
