(cucumber). The parameter log Kf was predicted with soil pHca, logCEC and log OC. Transfer of soil pore-water Cd2+ to shoots was described with a power function (R2 = 0.73). The dataset was validated with 13 long-term contaminated soils (plus 2 control soils) ranging in Cd concentration from 0.2 to 300 mg kg−1. The series of equations predicting Cdshoot from pore-water Cd2+ were able to predict the measured data in the independent dataset (root mean square error = 2.2). The good relationship indicated that Cd uptake to cucumber shoots could be predicted with Cdpore and Cd2+ without other pore-water parameters such as pH or Ca2+. The approach may be adapted to a range of plant species.]]> Wed 23 Feb 2022 16:06:46 AEDT ]]> Effects of thermal treatments on the characterisation and utilisation of red mud with sawdust additive https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24638 Wed 11 Apr 2018 14:14:24 AEST ]]> Phycoremediation of dairy and winery wastewater using Diplosphaera sp. MM1 https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26960 Diplosphaera sp. and was designated strain MM1. The growth of this strain was evaluated in different diluted dairy and winery wastewaters. The highest algal biomass production (up to 2.3 g L-1) was obtained in dairy wastewater (D3; dairy wastewater 1:2 deionised water) after 14 days of culture. However, for winery wastewater, the highest algal biomass production (up to 1.46 g L-1) was obtained in wastewater combination W2 (winery wastewater 1:1 deionised water) after 14 days of culture. Turbid dairy wastewater with high concentration of nitrogen and phosphorous slowed down the initial growth of the alga. However, at the end of day 14, biomass production was nearly twofold higher than that of winery wastewater. The findings from both types of wastewater suggest that Diplosphaera sp. MM1 has potential for its application in generating biomass with simultaneous remediation of nutrient-rich wastewater.]]> Sat 24 Mar 2018 07:27:01 AEDT ]]> Competitive sorption of cadmium and zinc in contrasting soils https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30028 Sat 24 Mar 2018 07:24:22 AEDT ]]>
