Soil contamination by polycyclic aromatic hydrocarbons (PAHs) is a widespread concern due to the high potential for human exposure through inhalation, ingestion, and dermal contact. In this study, we compared the efficiency of three different methods for PAHs extraction from model samples, including ultrasonic (US), mechanical shaking and purification with commercial QuEChERS kit (Shq), and ultrasonic extraction coupled with QuEChERS (USq) by gas chromatography coupled to a triple quadrupole tandem mass-spectromet...

Surfactants play an important role in enhanced oil recovery by creating an oil-water emulsion that will be easier to recover from the reservoir. It is known that sulfatereducing bacteria (SRB) can use surfactants as a carbon source, which can increase the biological accumulation of sulfides and, accordingly, the corrosion of oil production equipment. Thus, all new surfactants used in oil production need to be pre-tested for SRB. The aim of this study was to evaluate the effect of four new groups of synthesized sur...
