LR performed better than RF and GBM in terms of accuracy, sensitivity, specificity, kappa, precision, log loss, F1score, and MCC. From the better-performing LR model, bioavailable As (BAs), TAs, AvFe, and OC were significant variables for grain As. From the partial dependence plots (PDP) and individual conditional expectation (ICE) of the LR model, 5.70 mg kg−1 was estimated to be the limit for BAs in soil.]]> Wed 28 Feb 2024 15:34:22 AEDT ]]> Partial replacement of seawater with crude salt in giant freshwater prawn Macrobrachium rosenbergii hatchery operation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:53347 Wed 22 Nov 2023 10:26:00 AEDT ]]> Antimonate sequestration from aqueous solution using zirconium, iron and zirconium-iron modified biochars https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43505 Wed 21 Sep 2022 10:29:26 AEST ]]> Distribution, contamination status and source of trace elements in the soil around brick kilns https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47139 Wed 14 Dec 2022 15:20:30 AEDT ]]> Varietal differences influence arsenic and lead contamination of rice grown in mining impacted agricultural fields of Zamfara State, Nigeria https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47379 Mon 16 Jan 2023 13:46:54 AEDT ]]> Arsenic in Peruvian rice cultivated in the major rice growing region of Tumbes river basin https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41080 Fri 22 Jul 2022 17:04:21 AEST ]]>
