The Scanning Electron Microscope (SEM) images illustrated wrinkled and fractured surfaces due to degradation. The adsorption of dissolved organic matter onto microbeads was confirmed through FT-IR microscopy, while using Inductively Coupled Plasma Mass Spectrometer (ICP-MS) the presence of trace metals including Cd (2.34 ng g⁻¹), Cu (180.64 ng g⁻¹), Ni (12.69 ng g⁻¹), Pb (1.17 ng g⁻¹), Sb (14.43 ng g⁻¹), and Zn (178.03 ng g⁻¹) was revealed. Surface modified microbeads were capable of adsorbing Cu compared to the pure microbeads, which may be attributed to the complexation of Cu with dissolved organic matter associated with the microbeads in the matrix. It was further revealed that the biosolids derived microbead-metal complexes decreased soil respiration (up to ∼ 26%) and dehydrogenase activity (up to ∼ 39%). Hence, microbeads reaching biosolids during wastewater treatment are likely to serve as a vector for trace element contamination, transportation, and toxicity when biosolids are applied to soil.]]> Wed 29 May 2019 11:33:56 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49315 Wed 28 Feb 2024 14:48:43 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33205 Wed 12 Sep 2018 16:43:02 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:45846 Wed 11 Jan 2023 10:20:44 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39613 Wed 10 Aug 2022 11:41:40 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46743 Wed 07 Feb 2024 14:57:34 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36343 Wed 01 Apr 2020 13:32:39 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32627 Tue 26 Jun 2018 15:05:16 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:31956 −1 biosolids. Soil samples were analyzed for SOC fractions, including total organic carbon (TOC), labile, and non-labile carbon contents. The natural abundances of soil δ¹³C and δ¹⁵N were measured as isotopic tracers to fingerprint carbon derived from biosolids. An automated soil respirometer was used to measure in-situ diurnal CO₂ fluxes, soil moisture, and temperature. Application of biosolids increased the surface (0–15 cm) soil TOC by > 45% at both sites, which was attributed to the direct contribution from residual carbon in the biosolids and also from the increased biomass production. At both sites application of biosolids increased the non-labile carbon fraction that is stable against microbial decomposition, which indicated the soil carbon sequestration potential of biosolids. Soils amended with biosolids showed depleted δ¹³C, and enriched δ¹⁵N indicating the accumulation of biosolids residual carbon in soils. The in-situ respirometer data demonstrated enhanced CO₂ fluxes at the sites treated with biosolids, indicating limited carbon sequestration potential. However, addition of biosolids on both the clay loam and sandy loam soils found to be effective in building SOC than reducing it. Soil temperature and CO₂ fluxes, indicating that temperature was more important for microbial degradation of carbon in biosolids than soil moisture.]]> Thu 21 Oct 2021 12:52:20 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36281 Thu 19 Mar 2020 17:51:37 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:33451 Thu 12 Sep 2019 09:29:00 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38565 Thu 04 Nov 2021 13:16:08 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24017 Sat 24 Mar 2018 07:16:45 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38968 Mon 21 Mar 2022 14:34:30 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46864 Mon 05 Dec 2022 08:29:59 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39712 Fri 17 Jun 2022 17:10:04 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38434 Fri 10 Sep 2021 15:32:32 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37316 Fri 02 Oct 2020 15:25:07 AEST ]]>
