“…Analysis of toxic elements such as lead and mercury also revealed that the two plants had an appreciable amount of these elements which can be as a result of absorption from the environment. The metal concentrations of vegetables in this study were significantly different and could be attributed to the differences in their morphology and physiology for heavy metal uptake, exclusion, accumulation, and retention (Rahmdel et al, ).…”

“…Iron plays a crucial role as an oxygen carrier from lungs to body tissues, as a transport medium for electrons within cells and an integral part of important enzyme systems such as cytochromes (Moyo et al, ). The mineral content found in African leafy vegetables has been reported to exceed the levels found in exotic vegetables such as cabbage (Maseko et al, ; Rahmdel et al, ). Analysis of toxic elements such as lead and mercury also revealed that the two plants had an appreciable amount of these elements which can be as a result of absorption from the environment.…”

Wild indigenous vegetables make considerable contributions to food baskets among subsistence farmers in sub‐Saharan Africa. The aim of this study was to evaluate the proximate analysis, mineral composition, vitamin C content, β‐carotene content, and GC‐MS profile of crude methanolic extracts of Asystasia mysorensis and Sesamum angustifolia . Crude extracts obtained through sequential extraction using ethyl acetate and methanol were screened for the presence of secondary metabolites. Functional groups present were determined with a Shimadzu FT‐IR spectrophotometer, while β‐carotene content and ascorbic acid content were evaluated using a Shimadzu HPLC and Shimadzu UV‐VIS spectrophotometer, respectively. Secondary metabolites present in the extracts were determined qualitatively using a Shimadzu GC‐MS system equipped with a NIST spectral database. From the results obtained, the two plants could supply the recommended daily requirement for micronutrient and vitamin C content needed for a healthy diet. The total phenolic and flavonoid contents in S. amgustifolia were higher as compared to A. myorensis; hence, their consumption is highly beneficial as some compounds identified in the GC‐MS profile have been reported to have medicinal properties. The findings on the mineral and chemical composition, GC‐MS profile of A. mysorensis and S. angustifolia indicate that their consumption may provide the recommended nutritional requirements needed for a healthy diet.

“…Fatigue in the night-time, beginning of the first food intake from the day, all linked with greater emphasis on eating behaviour in shift work, were identified as the main conditions for accidents and injuries at work (Gupta et al, 2019Azmi et al, 2020. Furthermore, in shift work in mines, there is high food consumption with a high content of heavy metals, e.g., water and vegetable intake above the standards established by various organizations such as FAO/WHO (Rahmdel et al, 2018).…”

“…In addition, more studies on the causes of accidents at work with food intake in the industries are necessary. It becomes a greater challenge when talking about mining (Nawab et al, 2016) since many studies refer to the effect of food intake in the vicinity of mines ( Zhuang et al, 2009;Bempah & Ewusi, 2016;Huang et al, 2017;Rahmdel et al, 2018;Fitzgerald et al, 2018;).…”

Introduction: Falls from heights represent one of the most frequent accidents in civil constructions, mainly caused by different roofing activities. The risks should be first evaluated by conducting safety inspections, and then implementing adequate control measures to eliminate or reduce the risks of accidents. New technologies facilitate those inspections and make the processes much more efficient. The objective of this study was to make a systematic review to analyse works which used a drone as a visual tool for such safety inspection activities, systematize main information needed to consider in developing future drone research in civil construction. Methodology: The research was carried out on the Brazilian platform for scientific journals and conferences called "CAPES Portal" through the Preferred Report for Systematic Reviews and Meta-analyzes (PRISMA) methodology.

“…Cadmium (Cd), zinc (Zn), lead (Pb) and copper (Cu) are the main elements that accumulate in staple foods, fruits and vegetables in mining areas or industrial-polluted fields [9][10][11][12]. Recent publications increasingly focus on vegetables as healthy foods, but vegetables still face exposure to toxic metal contamination [9,11,[13][14][15][16][17]. Most of these studies quantify multiple toxic metals in vegetables, but few of them mention the negative effects of copper upon growth and production in leafy vegetables [9,13,14,16].To improve food safety from toxic metal contamination, it is an efficient strategy to predict the toxic metal contamination of crops by using the toxic metal information in the soil.…”

Copper (Cu), a toxic metal pollution found in the soil and water of industrialized areas, causes continuous issues for agriculture product contamination and human health hazards. However, information on copper phytotoxicity and its accumulation in vegetables is largely unknown. To evaluate the related agricultural loss and health risks, it is necessary to assess copper phytotoxicity and develop prediction models for copper concentration in vegetables. Here, we assess the growth performance and copper concentration of four leafy vegetables: Water spinach, amaranth, pakchoi, and garland chrysanthemum in copper-contaminated soil. The plant’s height and fresh weight is dramatically reduced when the soil copper concentration is over ~250 mg·kg−1. This yield reduction and copper accumulation are associated with an increase of soil copper concentration, suggesting high copper phytotoxicity levels in plants and soil. The prediction models of plant copper concentration were developed using multiple regressions based on one-step extractions of the soil copper as independent variables. One prediction model derived for amaranth copper using hydrochloric acid (HCl)-extractable and ethylenediaminetetraacetic acid (EDTA)-extractable copper from soil is able to describe 78.89% of the variance in the measured copper. As a result, the phytotoxic copper level for four leafy vegetables is revealed. Although the prediction models may not be universal, the predicted and phytotoxic copper levels are useful tools for evaluating vegetable yield and daily copper intake.
