The results showed that KMnO₄ pre-oxidation achieved a slightly more effective Mn removal, and was almost unaffected by the initial dissolved organic carbon (DOC) concentrations. PMS/Fe²⁺ removed UV254 more efficiently (above 90% at a dose of 0.25 mmol/L), compared with KMnO₄ (less than 60% UV254 removal). According to X-ray photoelectron spectroscopy (XPS) analysis of aggregates, both KMnO₄ and Fe²⁺/PMS oxidation resulted in the formation of MnO2 precipitate. Electron paramagnetic resonance(EPR) analysis demonstrated that only the reactors dosed with PMS/Fe²⁺ were able to generate the highly reactive hydroxyl radical(·OH). The production of ·OH caused significant rupture of algal cells and thus higher algal removal compared to the treatment with KMnO₄ (whereby insignificant cell breakage was observed). The cell rupture resulted in higher amounts of organic matter released in the systems containing PMS/Fe²⁺, as demonstrated by excitation-emission matrix (EEM) and protein analysis. Despite the elevated level of organic matter, adding PMS/Fe²⁺ was found to notably mitigate membrane fouling due to the formation of large flocs (311–533 μm) as well as the elimination of major ceramic membrane foulants, i.e. humic substances.]]> Wed 22 Mar 2023 17:30:46 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46002 Wed 07 Feb 2024 16:35:26 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47440 Wed 07 Feb 2024 14:39:59 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52149 Wed 04 Oct 2023 10:20:53 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38915 Wed 02 Mar 2022 15:01:20 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50961 Tue 22 Aug 2023 11:24:20 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54213 Tue 13 Feb 2024 11:50:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46378 Thu 17 Nov 2022 10:30:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35868 Thu 14 Apr 2022 11:01:33 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45690 Thu 03 Nov 2022 09:21:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32991 In utero exposure to particulate matter (PM) from a range of sources is associated with adverse post-natal health; however, the effect of maternal exposure to community-sampled PM on early post-natal lung and immune development is poorly understood. Objectives: Using a mouse model, we aimed to determine whether in utero exposure to PM alters early post-natal lung function and immune cell populations. We used PM collected from ceiling voids in suburban houses as a proxy for community PM exposure. Methods: Pregnant C57BL/6 mice were intranasally exposed to ceiling derived PM, or saline alone, at gestational day (E) 13.5, 15.5, and 17.5. When mice were two weeks old, we assessed lung function by the forced oscillation technique, and enumerated T and B cell populations in the spleen and thymus by flow cytometry. Results: Maternal exposure to PM impaired somatic growth of male offspring resulting in reduced lung volume and deficits in lung function. There was no effect on thymic T cell populations in dams and their male offspring but PM decreased the CD4 +CD25 + T cell population in the female offspring. In contrast, maternal exposure to PM increased splenic CD3 +CD4 + and CD3 +CD8 + T cells in dams, and there was some evidence to suggest inhibition of splenic T cell maturation in male but not female offspring. Conclusions: Our findings suggested that maternal exposure to ceiling void PM has the capacity to impair early somatic growth and alter early life immune development in a sex specific manner.]]> Thu 03 Feb 2022 12:19:29 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48217 Sat 11 Mar 2023 12:36:47 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44805 0.9, p < 0.001), which was affected by plant identity and P levels.
