The target hazard quotient (THQ) of each heavy metal was THQ < 1.0 (except Ni in few samples), indicating that consumers have no non-cancer risk when exposed to a single heavy metal. However, hazard index (HI) values of heavy metals were greater than unity in contaminated WC and AW for adults and children. Meanwhile, WC, AW, and SP samples for children emerged as potential health risks of inhabitants in the studied areas. The outcomes of the present investigation might assist the regulatory bodies concerned in setting new strategies through monitoring the quality of marketed vegetables to minimize the risks to humans.]]> Wed 13 Sep 2023 13:30:19 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54510 Tue 27 Feb 2024 15:38:55 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55146 Tue 16 Apr 2024 15:15:23 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37709 Aloe vera gel has drawn serious attention to the scientific community as one of the promising bio-preservatives due to its human health benefit and antimicrobial properties. The packaging of fruits using polythene bag is already a common practice. Thus, this study was conducted to evaluate the effect of no packaging and packaging with both perforated and unperforated polythene, together with Aloe vera gel coated and uncoated papaya fruits on post-harvest ripening behaviour and physicochemical properties when stored at room condition (25 ± 2℃ temperature and 80-85 % relative humidity). The results showed that Aloe vera gel coating alone delayed colour development during storage compared to the control (no packaging without Aloe vera gel). After 12 days of storage (DAS), the weight loss and moisture content of fruits treated with only Aloe vera gel were 11.7% and 89.9% respectively, whereas in control, the weight loss was 25.2% and moisture content was 87.1%. Moreover, soluble solids concentration (SSC) and disease severity were reduced as around 3% and 29% respectively, for coated compared to uncoated fruits. Similar to Aloe vera gel coating, packaging of papaya fruits with only both types of polythene bag showed better performance compared to control but not as much as Aloe vera gel coating alone. In addition, if the fruits are coated with Aloe vera gel as well as packed with polythene bag their edible quality drastically reduces once the fruits reach their peak climacteric or ripening stage, although these results were more severe with unperforated polythene compared to perforated polythene bags. These findings also suggest that Aloe vera gel as an edible coating could be used commercially for extending the storage life of papaya fruits for up to 14 days, while packaging of Aloe vera gel-coated papaya fruits in polythene bags must be avoided during, storage, transportation, and marketing. In addition, this is in accordance with the need to avoid the use of non-recycled plastic material due to its pollution effects on ecosystems worldwide.]]> Thu 28 Oct 2021 12:37:09 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49212 Sun 07 May 2023 09:30:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50626 100%) for children and HQ > 1 for both children and adults, suggesting their potential acute and chronic health hazards.

Well-decomposed soil OM, consisting of C–H and Cdouble bondO functional groups, enhanced glyphosate sorption, whereas partially decomposed/undecomposed OM facilitated desorption process. Desorption of glyphosate was favoured in seven of nine selected soils due to adverse hysteresis effects (HI = 0.74–1.0). The higher values of leachability index (0.31–1.0) and groundwater ubiquity score (1.60–3.44) calculated for the urban soils indicated the great leaching potential of glyphosate from soil surface to waterbodies. Use of glyphosate on impermeable surfaces might directly contaminate water sources and affect potability of water, non-target biota, and food safety. The calculated values of cancer risk (10⁻⁸‒10⁻¹²) and hazard quotient (1.47 x 10⁻⁶‒4.12 x 10⁻⁶) suggested that the human exposure to glyphosate-contaminated soils through dermal, ingestion and inhalation pathways might cause negligible or no carcinogenic and non-carcinogenic risks to humans. Therefore, glyphosate should be applied judiciously at recommended concentrations in the urban landscapes, mainly on impervious surfaces, to minimize its health impacts in humans and environment.]]> Fri 27 May 2022 10:34:27 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39741 Fri 17 Jun 2022 18:20:04 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54837 Fri 15 Mar 2024 11:55:49 AEDT ]]>
