The average concentrations (mg kg−1) of toxic trace elements were as follows: As: 0.17, Cr: 0.18, Ni: 0.55 and Pb: 0.18, while 7% and 40% of the rice samples surpassed, respectively, the EU recommended limits of As and Pb. This study revealed that rice could be a primary exposure pathway of toxic elements, leading to either noncarcinogenic or carcinogenic health problems for daily rice consumers. The non-carcinogenic health risk was mainly associated with As which contributed 77% to the hazard index. The carcinogenic risk measured as incremental lifetime cancer risk (ILCR) was high (>10−4) with As, Cr and Ni, while Pb showed a moderate (<10−4) carcinogenic risk to adults. Rice can substantially be contaminated by trace elements other than As with potential human health risks. Consequently, regular monitoring of the marketed rice grain is demanded, backed up by viable mitigation strategies for reducing toxic elements uptake by rice grains.]]> Wed 28 Feb 2024 15:54:22 AEDT ]]> Geographical variation and age-related dietary exposure to arsenic in rice from Bangladesh https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30718 n = 162) with the highest fraction being 98.6%. The daily intake of inorganic As from rice ranged between 0.38 and 1.92 µg/kg BW in different districts. The incremental lifetime cancer risk (ILCR) for individuals due to the consumption of rice varied between 0.57 × 10-3 to 2.88 × 10-3 in different districts, and 0.54 × 10-3 to 2.12 × 10 -3 in different varieties, higher than the US EPA thresho ld.

Most of the cereals and vegetables showed a higher value than 10−6, indicating a potential cancer risk; however, fruits and pulses showed lower risk only marginally exceeding the lower allowable limit (i.e., 10−6).]]> Wed 12 Jul 2023 14:04:45 AEST ]]> Arsenic in rice: genotypic variation and its bioavailability with respect to human health risk assessment https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30686 Wed 11 Apr 2018 13:21:22 AEST ]]> Translocation of soil arsenic towards accumulation in rice: magnitude of water management to minimize health risk https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45315 1) and carcinogenic risks (CR > 1.010–4) while AWD lowered health risks compared to CF.

Arsenic intake variables and three indicators of hypertension risks (general hypertension, low-density lipoprotein (LDL) and high-density lipoprotein (HDL)) were derived, and any relationship was quantified using a series of crude and multivariable log-linear or logistic regression models. The prevalence of general hypertension was 40% for the studied population. The median level of HDL was 45 mg/dL while median value of LDL was 114 mg/dL. Apart from a marginally significant positive relationship between As intake from rice and the changes of LDL (p-value = 0.032), no significant positive association between As intake and hypertension risks could be ascertained. In fact, Astotal was found to be associated with lower risks of general hypertension and higher levels of HDL (p-value = 0.020 and 0.010 respectively) whilst general hypertension was marginally associated with lower Aswater (p-value = 0.043). Due to limitations regarding study design and residual confounding, all observed marginal associations should be treated with caution.]]> Thu 27 Oct 2022 09:13:21 AEDT ]]> Planting for Food and Jobs (PFJ): A panacea for productivity and welfare of rice farmers in Northern Ghana https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:56045 Thu 25 Jul 2024 17:49:17 AEST ]]> Root iron plaque on wetland plants as a dynamic pool of nutrients and contaminants https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30318 Sat 24 Mar 2018 07:31:51 AEDT ]]> Cadmium in rice with reference to water management and cultivar variation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38834 Mon 29 Jul 2024 17:57:34 AEST ]]> Reduction in arsenic toxicity and uptake in rice (Oryza sativa L.) by As-resistant purple nonsulfur bacteria https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36508 Rhodopseudomonas palustris C₁ and Rubrivivax benzoatilyticus C₃₁ to ameliorate As toxicity and to reduce As uptake in rice. Strain C₁ was superior to strain C₃₁ for siderophore production. The mixed culture (1: 1) was most effective in reducing the toxicity of As species [As(III) and/or As(V), each 30 mg/l] by yielding maximal germination index that related to α- and β-amylase activities in two Thai rice cultivars (HomNil: HN and PathumThani 1: PT). Arsenic toxicity to the seed germination followed the order: mixed As species > As(III) > As(V); and the toxicity was reduced in inoculated sets, particularly with a mixed culture. The mixed culture significantly enhanced rice growth under As stress in both rice cultivars as indicated by an increase in the production of chlorophyll a and b, and also supporting the non-enzymatic (carotenoids, lipid oxidation, and nitric oxide) and enzymatic (superoxide dismutase, ascorbate peroxidase, catalase, and glutathione reductase) activities. These were concomitant with productions of 5-aminolevulinic acid, indole-3-acetic acid, exopolymeric substances, and siderophores which significantly reduced As accumulation in treated rice. It can be concluded that the mixed culture has great potential to ameliorate rice from As toxicity by preventing As species entry into rice for enhancing rice growth and also for reducing As accumulation to produce safe rice from rice grown in contaminated paddy fields.]]> Mon 25 May 2020 12:29:48 AEST ]]> Risk and benefit of different cooking methods on essential elements and arsenic in rice https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32809 Mon 23 Sep 2019 13:39:40 AEST ]]> Understanding and manipulating sucrose phloem loading, unloading, metabolism, and signalling to enhance crop yield and food security https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18695 Mon 20 Jul 2015 17:48:33 AEST ]]> Evaluation of manganese application after soil stabilization to effectively reduce cadmium in rice https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49677 Fri 26 May 2023 16:45:41 AEST ]]> Exploring relative deprivation theory in the rice industry: planting for food and jobs (PFJ) in northern Ghana https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46387 Fri 25 Nov 2022 11:01:07 AEDT ]]> Arsenic in Peruvian rice cultivated in the major rice growing region of Tumbes river basin https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41080 Fri 22 Jul 2022 17:04:21 AEST ]]> Morpho-physiological responses of rice to salicylic acid under drought stress https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53097 Fri 17 Nov 2023 11:33:14 AEDT ]]> Arsenic in the Soil-Plant-Human Continuum in Regions of Asia: Exposure and Risk Assessment https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54822 Fri 15 Mar 2024 08:36:58 AEDT ]]> Geographical variation of cadmium in commercial rice brands in Bangladesh: human health risk assessment https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39997 n = 144) were collected from the markets of 16 districts of Bangladesh to determine the distribution, regional variability and associated health risk from Cd. The mean and median concentrations of Cd in rice were 44 μg/kg and 34 μg/kg, respectively, ranging between 1 and 180 μg/kg, dry weight. The Cd concentrations of the rice samples did not exceed the safe limit of EU/CODEX but 9% exceeded the safe limit of FSANZ (Food standards Australia New Zealand) values. Results indicated that there were significant variations of Cd among (33%) and within (67%) the districts. Some rice brands such as Najirshail, Katarivogh and Chinigura had Cd levels of 81, 70 and 68 μg/kg, respectively. Cadmium ingested on a daily basis ranged between 0.09 and 0.58 μg/kg body weight (bw) with the incremental lifetime cancer risk (ILCR) for individuals varying between 1.35 x 10−3 and 8.7 x 10−3 in different districts. The age groups (2–5 yrs) and (6–10 yrs) experienced higher risks than others and both males and females were found to be susceptible from Cd exposure of rice.]]> Fri 15 Jul 2022 10:11:38 AEST ]]>
