This research outcome will provide a foundation for future research on metal(loid)s and will help in pertinent policy-making by the relevant authorities in Bangladesh.]]> Wed 10 Jul 2024 09:25:10 AEST ]]> Accumulation and distribution of metal(loid)s in the halophytic saltmarsh shrub, Austral seablite, Suaeda australis in New South Wales, Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40286 1) and lower for Pb and As (root BCFs <1). Substantial barriers for translocation from roots to stems were identified for all metal(loid)s (stem TFs; 0.07-0.68). Conversely, unrestricted flow from stems to leaves was observed for all metal(loid)s at unity or higher (leaf TFs = 1). Strong linear relationships between sediment and root for Zn and Pb were observed, indicating roots as a useful bioindicator.]]> Wed 07 Jun 2023 11:49:24 AEST ]]> Global patterns of accumulation and partitioning of metals in halophytic saltmarsh taxa: a phylogenetic comparative approach https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39208 1). Further, there is significant translocation from roots to shoot for Cu, Zn and Cd (≤ 1), however, Pb is less mobile (TF = 0.65). Patterns of accumulation were similar among families, except greater Cd accumulation to roots in members of Juncaceae. Patterns of uptake to roots and translocation to leaves were broadly similar among plant type, plant form, habitat and photosynthetic mode. Zinc is lower in the leaves of salt-secreting species for some closely related taxa, suggesting some species co-excrete sodium (Na+) and Zn2+ through glands in leaf tissue. Salinity tolerance has no relationship to metal uptake and translocation. Translocation of Zn is greater at lower Zn sediment exposures, reflecting its active uptake and essentiality, but such bias does not affect outcomes of analyses when included as a covariate.]]> Wed 03 May 2023 14:02:01 AEST ]]> Different levels of arsenic exposure through cooked rice and its associated benefit-risk assessment from rural and urban populations of West Bengal, India: a probabilistic approach with sensitivity analysis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52564 1 has been observed for all age groups from the exposed area and adult male group from the control area. Adults and children from rural area showed that ingestion rate (IR) and concentration are the respective influencing factors towards cooked rice As, whereas IR is solely responsible for all age groups from urban area. A vital suggestion is to reduce the IR of cooked rice for control population to avoid the As-induced health risks. The average intake (μg/day) of micronutrients is in the order of Zn > Se for all the studied populations and Se intake is lower for the exposed population (53.9) compared to the apparently control (140) and control (208) populations. Benefit-risk assessment supported that the Se-rich values in cooked rice are effective in avoiding the toxic effect and potential risk from the associated metal (As).]]> Tue 17 Oct 2023 15:41:25 AEDT ]]> eDNA metabarcoding reveals shifts in sediment eukaryote communities in a metal contaminated estuary https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50883 Tue 15 Aug 2023 10:19:15 AEST ]]> Salinity intrusion affects early development of freshwater aquaculture species pabda, Ompok pabda https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54205 Tue 13 Feb 2024 11:43:46 AEDT ]]> The accumulation and distribution of arsenic species and selected metals in the saltmarsh halophyte, spiny rush (Juncus acutus) https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47030 Tue 13 Dec 2022 14:08:40 AEDT ]]> Metal(loid) uptake and partitioning within the saltmarsh halophyte, Juncus kraussii https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48849 Thu 20 Apr 2023 10:30:52 AEST ]]> Metals in saltmarsh ecosystems: an assessment from global to local scales https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55911 Thu 04 Jul 2024 15:36:25 AEST ]]> Metal(loid) accumulation in the leaves of the grey mangrove (Avicennia marina): Assessment of robust sampling requirements and potential use as a bioindicator https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48217 Sat 11 Mar 2023 12:36:47 AEDT ]]> Upregulation of antioxidant enzymes contribute to the elevated tolerance of Juncus acutus offspring from metal contaminated environments. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54976 Mon 25 Mar 2024 15:21:19 AEDT ]]> Uptake and distribution of metal(loid)s in two rare species of saltmarsh, blackseed samphire, Tecticornia pergranulata, and narrow-leafed wilsonia, Wilsonia backhousei, in New South Wales, Australia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54729 Mon 11 Mar 2024 14:11:20 AEDT ]]> Offspring of metal contaminated saltmarsh (Juncus acutus) exhibit tolerance to the essential metal Zn but not the nonessential metal Pb https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50761 Mon 07 Aug 2023 14:08:10 AEST ]]> Legacy metal contamination is reflected in the fish gut microbiome in an urbanised estuary https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52681 Fri 20 Oct 2023 09:30:49 AEDT ]]> Some reproductive and biometric features of the endangered Gangetic Leaf Fish, Nandus nandus (Hamilton, 1822): Implication to the baor fisheries management in Bangladesh https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54829 0.90) values indicate that length parameters are profoundly associated with one another. In the LWR formula (W = aLb), higher exponent b values (b > 3.0) were demonstrating a positive allometric growth with a high correlation coefficient (r2 > 0.94). Moreover, monthly gonadosomatic index and dobriyal index fluctuations suggest the primary breeding season of this fish is from March to July. Data revealed the breeding time was associated strongly with the rainfall and air temperature (p < 0.05). The results of our study exposed a cutting-edge biometric feature of this endangered species that would be applicable for fish stock evaluation and making management strategies and conservation policy for this valuable fish resource.]]> Fri 15 Mar 2024 11:55:16 AEDT ]]> Sumithion induced structural erythrocyte alteration and damage to the liver and kidney of Nile tilapia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49381 Fri 12 May 2023 14:27:16 AEST ]]>
