The results revealed that every vegetable contained the highest concentration of Zn range from 15 ± 1.4 to 50 ± 4.0 mg/kg fresh weight. Trace metals in vegetables exceeded the permissible level of FAO and WHO standard. The non-carcinogenic and carcinogenic risks were estimated on the basis of estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI) and target carcinogenic risks (TRs). The EDI values of all trace metals were below the maximum tolerable daily intake (MTDI). Total target hazard quotient (TTHQ) were greater than 1, indicated that if people consume these types of vegetables in their diet, they might pose risk to these metals. Finally, the total cancer risks (TRs) values were 6.4 × 10−3 for As and 8.7 × 10−5 for Pb which were greater than threshold value of USEPA (10−6), indicating that the consuming inhabitants of these vegetables are exposed to As and Pb with a lifetime cancer risk.]]> Wed 28 Feb 2024 15:20:23 AEDT ]]> Sorption of PFOS in 114 well-characterized tropical and temperate soils: application of multivariate and artificial neural network analyses https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39790 d) ranged from 5 to 229 mL/g (median: 28 mL/g), with 63% of the Fijian soils and 35% of the Australian soils showing Kd values that exceeded the observed median Kd. Multiple linear regression showed that TOC, amorphous aluminum and iron oxides contents, anion exchange capacity, pH, and silt content, jointly explained about 53% of the variance in PFOS Kd in soils. Variable charge soils with net positive surface charges, and moderate to elevated TOC content, generally displayed enhanced PFOS sorption than in temperate or tropical soils with TOC as the only sorbent phase, especially at acidic pH ranges. For the first time, two artificial neural networks were developed to predict the measured PFOS Kd (R2 = 0.80) in the soils. Overall, both TOC and surface charge characteristics of soils are important for describing PFOS sorption.]]> Thu 23 Jun 2022 14:06:17 AEST ]]> In support of urban adaptation: a participatory assessment process for secondary cities in Vietnam and Bangladesh https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31595 Sat 24 Mar 2018 08:45:01 AEDT ]]> Arsenic, iron and chloride in drinking water at primary school, Satkhira, Bangladesh https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36754 1 for arsenic in the tube wells water of seven Upazilas at Satkhira district.
