Limited aqueous availability of hydrophobic organic contaminants and nonaqueous phase liquids in subsurface environment may seriously impair the effectiveness of traditional in situ chemical oxidation (ISCO). To tackle the issue, a combination of surfactants and thermally activated persulfate was proposed to enhance the aqueous availability and consequent oxidation of organic contaminants. The compatibility of eight representative nonionic, monovalent anionic, and divalent anionic surfactants with persulfate at various temperatures was first studied, to identify suitable surfactants that have high aqueous stability and low oxidant demands to couple with thermally activated persulfate...

EDITORIAL
Boye L Jensen
In the present issue of Acta Physiologica(1) , Khan et al. in their article "Improvement in baroreflex control of renal sympathetic nerve activity in obese Sprague-Dawley rats following immunosuppression" confirm that obesity-related hypertension involves resetting of the arterial baroreceptor to a state of less sensitivity and relate this mechanistically to inflammation-induced altered renal afferent nerve activity (1) . Pharmocological treatment with the calcineurin phosphatase inhibitor-type immunosuppressant tacrolimus attenuated inflammation, reversed, paradoxically, the hypertension and restored baroreceptor sensitivity similar to the effect of renal denervation...

Many regions in Canada are facing increasing environmental threats posed by oil and gas exploitation and transportation. These contaminated lands are inevitably subjected to seasonal and diurnal freeze-thawing cycles (FTCs). However, knowledge about the effect of FTCs on the behaviours of hydrophobic contaminants during the aging process of soil is limited. This study investigated the desorption characteristics of phenanthrene in aging soils in the presence of the biosurfactant rhamnolipid under diurnal and seasonal FTC treatments...
