During post-monsoon, none of the samples exceeded 50 µg L−1, but eight of them exceeded 10 µg L⁻¹. The Fe removal efficiencies of AIRPs were evident in more than 80% samples. Although As removal efficiency was found to be substantial, a cancer risk assessment indicates that hazard quotient (HQ) and carcinogenic risk (CR) of As in treated water for adults and children are above the threshold limits. Thus, additional reductions of As concentrations in treated water are needed to further reduce the excess cancer risk due to As in drinking water. Since 55% and 40% of the AIRPs were unable to remove As < 10 µg L⁻¹ during pre-monsoon and post-monsoon, further improvement including changes in AIRP design, regular cleaning of sludge, and periodic monitoring of water quality are suggested. Future research is needed to determine whether these modifications improve the performance of AIRPs.]]> Tue 15 Nov 2022 15:04:48 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39812 Thu 28 Jul 2022 15:29:19 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45345 −1 for 24 h by Zr–FeBC and Fe-BC at pH 5 and 4, respectively. Desorption studies were performed to investigate the reusability, cost-effectiveness and stability of the adsorbents Zr–FeBC and Fe-BC. The adsorption–desorption study suggests that both examined biochars have considerable potentiality as adsorbent candidates in removing as well as recovery of P from wastewaters. Results also reveal that the regenerated Zr–FeBC and Fe–BC could be utilized repetitively in seven adsorption–desorption cycles using NaOH as a desorbing agent, which greatly reduces the P-removal cost from wastewaters. Thus, P enriched biochar could potentially be used as fertilizer in the agriculture sector.]]> Thu 27 Oct 2022 15:20:47 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45149 Thu 27 Oct 2022 14:34:48 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45315 1) and carcinogenic risks (CR > 1.010–4) while AWD lowered health risks compared to CF.

Soil sampling was conducted in the inter row area of six vineyards, which differed by the age from planting: 0 (Age 0; just planted), 1, 3, 6, 13, and 25 years (Age 1, Age 3, Age 6, Age 13, and Age 25, respectively). The One Ponding Depth (OPD) approach was applied to ring infiltration data to estimate soil K_s with an α* parameter equal to 0.012 mm^-1. Soil bulk density for Age 0 was about 1.5 times greater than for Age 25, i.e., the long-term managed vineyards. Saturated hydraulic conductivity at Age 0 was 86% less than at Age 25. The planting works were considered a major factor for soil compaction and the reduction of hydraulic conductivity. Compared to the long-term managed vineyards, soil compaction was a very short-term effect given that BD was restored in one year due to ploughing. Reestablishment of K_s to the long-term value required more time.]]> Mon 23 Sep 2019 14:07:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32351 fs, of an unmanaged field affected by fire by means of single-ring infiltrometer runs and the use of transient and steady-state data analysis procedures. Sampling and measurements were carried out in 2012 and 2017 in a fire-affected field (burnt site) and in a neighboring non-affected site (control site). The predictive potential of different data analysis procedures (i.e., transient and steady-state) to yield proper K_fs estimates was investigated. In particular, the transient WU1 method and the BB, WU2 and OPD methods were compared. The cumulative linearization (CL) method was used to apply the WU1 method. Values of K_fs ranging from 0.87 to 4.21 mm·h^-1 were obtained, depending on the considered data analysis method. The WU1 method did not yield significantly different K_fs estimates between the sampled sites throughout the five-year period, due to the generally poor performance of the CL method, which spoiled the soil hydraulic characterization. In particular, good fits were only obtained in 23% of the cases. The BB, WU2 and the OPD methods, with a characterization based exclusively on a stabilized infiltration process, yielded an appreciably lower variability of the K_fs data as compared with the WU1 method. It was concluded that steady-state methods were more appropriate for detecting slight changes of K_fs in post-fire soil hydraulic characterizations. Our results showed a certain degree of soil degradation at the burnt site with an immediate reduction of the soil organic matter and a progressive increase of the soil bulk density during the five years following the fire. This general impoverishment resulted in a slight but significant decrease in the field-saturated soil hydraulic conductivity.]]> Mon 23 Sep 2019 13:14:44 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35506 Mon 19 Aug 2019 16:02:29 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48976 Fri 21 Apr 2023 09:22:46 AEST ]]>
