Interaction and variation of isotopic age, temperature, organic and inorganic solutes in Hungarian thermal waters [PDF]

open access: yes, 2009
The geochemical facies of Hungarian thermal waters were the object of this study. Samples were separated into groups by relative ages (δ18O values). Mature and immature subgroups were formed on the basis of dissolved (semi)volatile organic compounds. The

Investigation of microalgal tolerance and growth in simulated tailings pond water containing naphthenic acids

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Oil sands tailings ponds, such as those in northeastern Alberta, present environmental challenges due to slow sedimentation, water entrapment, and toxic naphthenic acids (NAs), which hinder water reclamation. This study assessed the tolerance and biodegradation potential of Chlorella vulgaris (C.
