“…The differences were significant for different samples at 95 % confidence level. In general, present results are in close agreement with those of reported in literature [5,[8][9][10][11][12][13][14][15][16][17]27]. In addition, FAO/WHO/ SASO has set a limit for heavy metal intake based on body weight for an average adult (60 Kg body weight).…”

The analytical parameters of the microwave assisted oven and of the inductively coupled plasma (ICP) method were extensively studied and well validated in terms of spectral lines (nm), linearity (R2), accuracy (recovery %), precision (RSDs), detection and quantification limits (LODs and LOQs). The validated analytical method was used to determine the contents of selected toxic trace elements (TTEs) in fresh fruit samples from Turabah Valley of Saudi Arabia. Samples were digested by a microwave-assisted oven at the ratio of 1:2.5 (v/v) (H2O2:HNO3). The R2 > 0.9990 or better, the recovery (%) were within the acceptable range (100 ± 8), the RSDs were below 4 %, the LODs and the LOQs were ranged between 0.0005-0.0556 mg kg-1 and 0.003-0.174 mg L-1, respectively. It was found that Al, Mn, Pb, As and Cd were detected in most analyzed samples, while Co, Ni and Cr were below the detection limits of the method. A considerable variation were observed with regard to TTEs concentrations in different studied fruit samples. TTEs content of fruits were compared with those of soil and well water samples in the same area. Elevated levels of Al were obtained in some fruit samples, while other elements were within the critical safety levels specified by the FAO/WHO/SASO. Some physico-chemical properties such as moisture, ash and total solid contents (%) of fruits were also estimated and compared with the reference values. The results indicate that the developed ICP method was well suited for determination of toxic and/or nutrient trace elements in fruits and possibly similar matrices.

“…Radwan and Salama [8] have reported heavy metal content in fruits and vegetables in Egypt. Sager [9] was able to determine the main and trace element contents of tomatoes grown in Austria. Todea et al [10] have studied the level from major-to-trace elements in different apple cultivars in Romania.…”

“…Compared to vegetative organs, REE in reproductive plant parts are only occasionally detectable or orders of magnitude lower compared to concentrations in plant leaves [18,146,227,228], indicating restricted REE allocation from soil to the plant and vegetative plant parts to the fruits (Tables 10 and 11). Dicots typically show higher shoot REE concentrations than monocots (Table 10, [74]), which could be attributed to a higher accumulation of Ca in dicots compared to grasses [229] and differences in below-ground functional traits related to nutrient acquisition, particularly of P, Fe, and Mn [14,55,74].…”

The rare earth elements (REE) comprise a group of 16 chemically very similar elements that occur widespread in rocks, soils, and water bodies, share similar ionic radii to the essential element Ca2+, and consequently also occur in biota. Given that REE form mainly trivalent cations, they also share similarities to Al3+. Compared to their chemical cognate Ca, they have a higher reactivity. Thus, their accumulation in soils may constitute a severe environmental threat. Over the last decades, the increasing use of REE in modern technology and fertilizers raised concerns about the pollution of soils and water bodies, which led to a rapidly increasing number of publications dealing with REE toxicity to plants, animals and humans, the fate of REE in soil–plant systems, REE cycling in ecosystems and impacts of REE pollution on food security. This review aims to give an overview of the current knowledge on the occurrence of REE in the total environment, including relevant environmental processes governing their mobility, chemical speciation and transfer from abiotic compartments into biota. Beginning with an overview of analytical approaches, we summarize the current knowledge on the ecology of REE in the lithosphere, pedosphere, hydrosphere and biosphere, including impacts of soil pollution on food security and public health.

“…Potassium is the most abundant mineral nutrient in fresh tomato fruits (Sager, 2017;Labate et al, 2018), while Mg is the mineral nutrient most frequently lacking in the human diet (White and Broadley, 2005). Phosphorus is one of the 17 key elements required in plant metabolism (Dixon et al, 2020) and is essential for human nutrition, but dietary P deficiency occurs very rarely, as it is contained in many foods and is well absorbed (Vorland et al, 2017).…”

Biodiversity in Tomatoes: Is It Reflected in Nutrient Density and Nutritional Yields Under Organic Outdoor Production?

et al. 2020

In many regions of the world, human nutrition is still characterized by an insufficient intake of essential nutrients like minerals such as iron (Fe) and zinc (Zn). In view of decreasing resources and a growing world population, the efficiency and the sustainability of cultivation systems should be considered not only in terms of crop yield and profit margin but also in terms of the yield of essential nutrients. Tomatoes are the most consumed vegetable in the world. Organic outdoor tomato cultivation is generally characterized by a higher diversity of varieties and lower fertilization input compared to conventional production. A 2-year field experiment with a set of 20 cultivars was performed to evaluate their variation regarding fruit mineral concentrations [potassium (K), calcium (Ca), magnesium (Mg), phosphorous (P), Fe, and Zn], their contribution to the dietary reference intake (DRI), and the nutritional yields (adults ha–1 year–1). Results show that mineral concentrations differed significantly by cultivar and by year. However, even though significant genotype-by-year effects appear, several cultivars exhibit high genotype stability across years for the single traits studied. Taking this together with medium-to-high heritability, genetics strongly controls most studied traits. Among the cultivars, the contribution of 100 g fresh fruits varied from 4.5 to 7.7% for K, 0.8 to 1.8% for Ca, 2.3 to 4.4% for Mg, 3 to 6.6% for P, 3.1 to 6.9% for Fe, and 1.9 to 4.2% for Zn to meet daily requirements. Based on average fruit yields per hectare, the cultivars varied with regard to the nutritional yields for all the studied minerals, but most strongly for Fe (44–120 adults ha–1 year–1) and Zn (22–84 adults ha–1 year–1). In terms of contribution to the DRI and nutritional yield for Fe, the cocktail cultivar “Bartelly F1” produced the highest results, while for Zn the salad cultivar “Bocati F1” showed the highest values. Our results show that the targeted use of tomato biodiversity in organic outdoor production can be suitable to achieve high fruit yields as well as to produce high nutritional yields per unit area, thus contributing to more effective land use and improved food security. These findings also provide valuable insights for tomato breeders to improve the tomato fruit quality while maintaining yield.
