The effect of S^o on Cr(VI) sorption is mediated through a decrease in soil pH, which facilitated an increased retention of Cr(VI) as measured by Freundlich sorption coefficient from 0.079 (in pristine soil, pH7.15) to 21.06L/kg (in S^o amended soil, pH4.08). Also, Fe(III) oxide addition at 5% has favoured for an increase in the retention of Cr(VI) (K_f =91.15L/kg). Cow manure promoted Cr(VI) reduction, possibly due to the presence of functional groups that are present along with dissolved organic carbon and also by increased microbial activity. It is concluded that the mitigation of Cr toxicity is brought about by the addition of amendments which manipulate the properties of soil to increase retention of Cr(III) and Cr(VI).]]> Thu 21 Oct 2021 12:51:17 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24839 Coelosphaerium sp., Synechococcus sp., Oscillatoria sp. and Chroococcus sp. to environmentally relevant concentrations of Cr⁶⁺, Cd²⁺ and Zn²⁺was assessed based on fluorescence change as a proxy for growth reduction. At 24 h exposure, the growth reduction inthe cyanobacteria followed the order: Zn²⁺ < Cr⁶⁺ ≤ Cd²⁺. Of the four cyanobacteria, Synechococcus was the most sensitive for Cr⁶⁺, where as Chroococcus was the most sensitive for Cd²⁺ and Zn²⁺. Sensitivity was gradually decreased by 96 h implying the acquisition of tolerance by cyanobacteria to heavy metal ions with prolonged exposure.]]> Sat 24 Mar 2018 07:11:19 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24996 Sat 24 Mar 2018 07:09:54 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41295 Mon 01 Aug 2022 12:09:39 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42616 Fri 26 Aug 2022 15:54:25 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43390 Fri 16 Sep 2022 09:37:21 AEST ]]>
