TEs displayed high variations within samples, reflecting many sources that control their concentrations in the coastal water. Most TEs displayed elevated concentrations in the east and west of the study area. The Na-Cl water type in the majority of investigated sites indicates excess alkaline elements and strong acid anions relative to alkaline earth cations and weak acid anions. Considering the saturation states of minerals, carbonate and evaporite minerals are oversaturated and unsaturated in surface water, respectively. Compositional interrelations between aqueous species showed that reverse cation exchange may have occurred. The excess SO42− content, derived from irrigation return flow and domestic greywater, probably plays a crucial role in the mobilization and transport of Zn and Pb by binding to sulfate ligands and forming aqueous complexes. Ecological risk assessment of TEs revealed that water in the majority of sites is safe in terms of As, Se, Pb, and Cd content, and unsuitable with respect to Zn and Cu. Acute and chronic toxicities of Cu and Zn are reported in several sites, thus coastal water cannot be used for fishery and protecting “nature reserve” purposes. However, industrial activity and tourism are safe to be conducted in most coastal water sites.]]> Wed 07 Feb 2024 15:26:27 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44954 −3, respectively. In regard to the synoptic-scale approach, eight directional and two vorticity types of the Lamb weather type (LWT) method are used in the analysis. Based on the results, poor air quality conditions are observed in all seasons during active southeasterly (SE, interaction between a low pressure over Italy and a high pressure over the Caspian Sea) circulation types (CTs). In winter, mainly easterly (E), SE, southerly (S), and anticyclonic (A) weather patterns result in above normal PM10 concentrations. In addition to these four CTs, southwesterly (SW) types also cause higher PM10 values in the spring season. During summer, SE, SW, westerly (W), and cyclonic (C) CTs are associated with above-normal PM10 values. During fall, obvious higher PM10 concentrations are found during SE, S, and A types.]]> Tue 25 Oct 2022 13:34:53 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51455 Tue 05 Sep 2023 18:15:02 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:166 Thu 25 Jul 2013 09:09:46 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39889 3 and HClO₄ at 2:1). Concentrations of heavy metals were determined using atomic absorption spectrophotometer (AAS). Principal component analysis (PCA) was performed to reduce multidimensional space of variables and samples. Observed mean concentrations of Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn were 164, 33.4, 295, 336, 634, 236, 1572, and 546 mg kg−1, respectively. Mean concentrations of all the heavy metals in urban area soil were higher than the WHO permissible limits. Correlation coefficient analysis showed positive correlation among Cd, Co, Cu, Ni, and Pb, whereas no obvious correlation for Cr and Mn was found with any other heavy metal. Zn was positively correlated with Co, Ni, and Mn, whereas negative correlation was found with Cr. Results showed that Pir Wadhai and COD were the most and least contaminated parts of the city, respectively, and this is attributed to the presence and absence of heavy traffic loads and industrial effluents.]]> Thu 21 Jul 2022 09:55:28 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55118 Thu 11 Apr 2024 08:26:26 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:13563 Sat 24 Mar 2018 10:35:57 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:1652 Sat 24 Mar 2018 08:30:28 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:12301 Sat 24 Mar 2018 08:11:38 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29543 Sat 24 Mar 2018 07:33:09 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37587 Mon 22 Feb 2021 11:59:53 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24989 Fri 01 Apr 2022 09:25:44 AEDT ]]>
