“…The two parameters bioconcentration factor (BCF) and the translocation factor (TF) were calculated. BCF was the ratio of the metal concentration in plant tissues to that in their rooted soils (Yang et al, 2009;Sun et al, 2009;Wang et al, 2009), and TF was the ratio of metal concentration in other plant parts to that in roots Wang et al, 2009 (Chen, 1996). The soil used was an irrigation-silt sandy soil, excavated from an oasis farm at 0-20cm depth with spade, and subsamples collected were mixed to obtain a composite sample in accordance with the standard method (Keith, 1996; Ministry of Environmental Protection of P.R.…”

“…Cadmium is a toxic trace element to plants and animals, and can cause damage even at very low concentrations (Wagner, 1993;Liu et al, 2007a;Wang et al, 2007;Xu et al, 2007;Huang et al, 2009;Su et al, 2009;Sun et al, 2009;Yang et al, 2009) and can be taken up by crops easily (Wagner, 1993;Liu et al, 2007a;Huang et al, 2009). In China, much soil has been polluted with Cd which is one of the most important and typical heavy metal pollutant (Chen, 1996;Su et al, 2009;Liu et al, 2010).…”

A pot experiment was conducted to study the bioaccumulation and translocation of cadmium (Cd) in wheat (Triticum aestivum L.) and maize (Zea mays L.) grown in the Cd-polluted oasis soil in northwest China. The results showed that Cd in the unpolluted oasis soil was mainly bound to carbonate fraction (F2) and Fe-Mn oxide fraction (F3). However, a marked change of the Cd fractionation was observed with increasing soil Cd concentrations, where the concentrations of Cd in F1 (exchangeable fraction), F2 and F3 increased significantly (P<0.001 for F1, F2 and F3). The correlation analysis between the fraction distribution coefficient (FDC) of Cd in the soil and Cd concentration accumulated in the two crops showed that Cd in F1 fraction in the oasis soil made the greatest contribution on the accumulation of Cd in the two crops. Higher bioconcentration factors (BCF) of Cd were observed in the two crops' shoots compared with grains, and low translocation factors (TF) of Cd in the grains were observed for both crops. Cd had a higher accumulation in the edible parts of the wheat, but lower accumulation in those of the maize. Therefore, wheat grown in Cd-polluted oasis soil has a higher risk to human health, whereas maize has a lower risk suggesting that wheat is not suitable for cultivation as crop and consumption by humans in the Cd-polluted oasis soil, but that maize is suitable for plantation.

“…Because the phytoavailability of Cd in soil is considerably affected by soil characteristics, the Cd accumulation capacity of different vegetables may be slightly different from that reported by many researchers (Lune and Zwart 1997;Wang et al 2006;Yang et al 2009Yang et al , 2010Zhang et al 2014). However, in general, leafy vegetables have a high Cd accumulation capacity, whereas fruiting vegetables and legume vegetables have a lower Cd accumulation capacity.…”

The cadmium (Cd) accumulation capacity of various vegetables and the relationship between Cd concentrations in edible parts of vegetables and those in soils were assessed by conducting field experiments at Cdcontaminated sites in northern and central Taiwan. In addition, to thoroughly assess Cd concentrations in vegetables and to understand the food safety of vegetables in Taiwan, 2257 paired vegetable and surface soil samples were collected from major vegetable production areas for Cd concentration analysis. According to the bioconcentration factors calculated, the Cd accumulation capacity varied considerably among the vegetable species tested, and the order of the five vegetables with the highest capacities is peanut (Arachis hypogaea L.) > amaranth (Amaranthus tricolor L.) > spinach (Spinacia oleraceae L.) > gynura (Gynura bicolor DC.) > okra (Hibiscus esculentus L.), whereas the order of the five vegetables with the lowest capacities is bitter gourd (Momordica charantia L.) < cucumber (Cucumis sativus L.) < asparagus bean (Vigna unguiculata (L.) Walp. ssp. sesquipedalis (L.) Verdc.) < snap bean (Phaseolus vulgaris L.) < sponge gourd (Luffa cylindrica Roem.). We derived 29 soil-plant transfer models of Cd for individual vegetable species based on available pools of the Cd, manganese (Mn), zinc (Zn), copper (Cu) and iron (Fe) concentrations; soil pH; and cation exchange capacity (CEC). According to the derived models, the available Cd, Mn and Zn concentrations, and pH, served as the main factors affecting Cd concentrations in the edible parts of vegetables, whereas the CEC and available Cu and Fe concentrations are less important factors. The data of previous studies and those of this study from major vegetable production areas, including 30 vegetable crops, were used to evaluate the safety of vegetables in Taiwan. The results indicated that the percentage of vegetables with Cd concentrations exceeding the regulatory concentration was 0.54%; therefore, the food safety concern is low. However, 9.8, 1.0, 0.9 and 0.6% of amaranth, cabbage (Brassica oleracea L. Capitata Group), Chinese cabbage (Brassica pekinensis Skeels.) and carrot (Daucus carota L.), respectively, had Cd concentrations in the edible parts exceeding the regulatory concentration. Particular attention should be paid when planning production areas for these vegetables. We recommend cultivating peanuts in fields with a soil Cd concentration < 0.33 mg kg −1. The bioconcentration factors and soil-plant transfer models derived in this study might serve as assessment tools for planning farming areas for these vegetables.

“…As concentrações de Cd na parte comestível da alface crespa, coentro, espinafre, rúcula e salsa são apresentadas na Tabela A razão de transferência solo-planta (Rt), definida como razão entre a concentração de MP na parte comestível de plantas (massa seca) e concentração total de MP no solo, foi usada para avaliar o potencial de transferência do Cd do solo para a planta (HARRISON;CHIRGAWI, 1989;HOODA et al, 1997;CUI et al, 2005;KHAN et al, 2008;YANG et al, 2009). A transferência do Cd do solo para a planta é função da propriedade do MP, das propriedades do solo e do genótipo das plantas.…”
