“…For example, root vegetables like carrots, potatoes and onions accumulate nickel when grown in contaminated soil or irrigated with contaminated water (Stasinos et al., 2014). The same has been observed in plants grown in paddy fields (Rahman et al., 2018).…”

The European Commission asked EFSA to update its previous Opinion on nickel in food and drinking water, taking into account new occurrence data, the updated benchmark dose (BMD) Guidance and newly available scientific information. More than 47,000 analytical results on the occurrence of nickel were used for calculating chronic and acute dietary exposure. An increased incidence of postimplantation loss in rats was identified as the critical effect for the risk characterisation of chronic oral exposure and a BMDL 10 of 1.3 mg Ni/kg body weight (bw) per day was selected as the reference point for the establishment of a tolerable daily intake (TDI) of 13 lg/kg bw. Eczematous flare-up reactions in the skin elicited in nickel-sensitised humans, a condition known as systemic contact dermatitis, was identified as the critical effect for the risk characterisation of acute oral exposure. A BMDL could not be derived, and therefore, the lowest-observed-adverse-effect-level of 4.3 lg Ni/kg bw was selected as the reference point. The margin of exposure (MOE) approach was applied and an MOE of 30 or higher was considered as being indicative of a low health concern. The mean lower bound (LB)/upper bound (UB) chronic dietary exposure was below or at the level of the TDI. The 95th percentile LB/UB chronic dietary exposure was below the TDI in adolescents and in all adult age groups, but generally exceeded the TDI in toddlers and in other children, as well as in infants in some surveys. This may raise a health concern in these young age groups. The MOE values for the mean UB acute dietary exposure and for the 95th percentile UB raises a health concern for nickel-sensitised individuals. The MOE values for an acute scenario regarding consumption of a glass of water on an empty stomach do not raise a health concern.

“…The result showed that an average of 2.8 mg kg −1 in triplicate samples was obtained ( Figure 4C). The concentration is low compared with normal paddy soil concentration above 8.3 mg kg −1 (Bogdan and Schenk, 2009;Rahman et al, 2018). Norton (2019) suggested a number of transporters are involved in As uptake and translocation in rice.…”

“…The concentration ranges between 1 and 6 mg kg −1 with a median concentration of ca 3.5 mg kg −1, and this is mainly due to geological sources (Ljung et al, 2006). The concentration is low compared with the levels in other geological countries that are normally over 8 mg kg −1 (Bogdan and Schenk, 2009;Camacho et al, 2011;Kong et al, 2018;Rahman et al, 2018). Since As concentration in paddy soils significantly impact As concentrations in rice grains (Bogdan and Schenk, 2009;Rahman et al, 2018), we hypothesize that production of rice in Uppsala fields would be a potential alternative to produce low As rice that meets the statutory requirements for rice consumed in Sweden and other countries.…”

“…High concentrations of metals, such as arsenic (As), mercury (Hg), and cadmium (Cd), in rice grains can result in chronic poisoning and can lead to impaired human health (Fontcuberta et al, 2011;Rahman et al, 2014;Huang et al, 2015;Singh et al, 2015;Awasthi et al, 2017;Chen et al, 2017;Li et al, 2018;Norton, 2019). The actual concentrations of metals in rice grain depend on the amount of metals in the cultivation environment and in the soil (Bogdan and Schenk, 2009;Satpathy et al, 2014;Zhao et al, 2015;Rahman et al, 2018) as well as differences in uptake between rice genotypic variations (Norton et al, 2014;Yan et al, 2019). Organic cultivation in relatively natural conditions on less contaminated soil can result in lower metal concentrations in grain (Satpathy et al, 2014;Zhao et al, 2015).…”

There is an urgent demand for low-arsenic rice in the global market, particularly for consumption by small children. Soils in Uppsala, Sweden, contain low concentrations of arsenic (As). We hypothesize that if certain japonica paddy rice varieties can adapt to the cold climate and long day length in Uppsala and produce normal grains, such a variety could be used for organic production of low-arsenic rice for safe rice consumption. A japonica paddy rice variety, "Heijing 5," can be cultivated in Uppsala, Sweden, after several years' adaptation, provided that the rice plants are kept under a simple plastic cover when the temperature is below 10 • C. Uppsala-adapted "Heijing 5" has a low concentration of 0.1 mg per kg and high protein content of 12.6% per dry weight in brown rice grain, meaning that it thus complies with all dietary requirements determined by the EU and other countries for small children. The high protein content is particularly good for small children in terms of nutrition. Theoretically, Uppsala-adapted "Heijing 5" can produce a yield of around 5100 kg per ha, and it has a potential for organic production. In addition, we speculate that cultivation of paddy rice can remove nitrogen and phosphorus from Swedish river water and reduce nutrient loads to the Baltic Sea and associated algae blooms.

“…Trace elements can originate from natural sources (e.g., parent materials, weathering of rocks, volcanic eruptions and soil erosion) and anthropogenic sources (e.g., industrialization, urbanization, vehicular emissions, mining activities, smelting, burning of fossil fuels and agricultural inputs such as fertilizers, pesticides, herbicides and fungicides [9,10]. However, currently anthropogenic activities significantly accelerate the accumulation of trace elements in the environment [11,12].…”

This study aimed to determine the concentration levels, potential sources and ecological risks of eleven trace elements, namely Cr, Fe, Co, Ni, Cu, As, Sb, Cd, Zn, Hg and Pb, in the soil from Huangpi district, Wuhan, Central China. Soil samples were collected from eighteen sites at soil depths of 1–10 and 10–20 cm and analyzed using Inductively Coupled Plasma-Mass Spectrometer ICP-MS (Thermo X SERIES 2, Scientific and Innovative Technology Co. Ltd., Beijing, China). The recorded mean concentration of the elements were in a decreasing order of Fe > Co > Cr > Ni > Pb > Cu > As > Cd > Sb > Zn > Hg. The mean concentration of trace elements, soil pH and total organic carbon (TOC) were higher at a soil depth of 1–10 cm. The obtained mean concentration of Cr, Co, As, Cd, Ni, Cu, Hg and Pb were above the soil background values of Wuhan and Hubei Province. The mean concentration values of Co, Ni and Cd, exceeded the recommended FAO (Food and Agriculture Organization)/ISRIC (International Soil Reference and Information Centre) (2004) and WHO/FAO (2001) values. Pearson’s correlation analysis illustrated that there was a strong and significant correlation between trace elements, whereas, a weak positive and negative correlation between elements and soil properties (pH and TOC). The principal component analysis (PCA) and cluster analysis (CA) result indicated that the concentration of trace elements in Huangpi soil were originated from anthropogenic sources. Potential ecological risk index (RI) of this study revealed that there is a high ecological risk of trace elements in the soil. Enrichment factor (EF) and geo-accumulation index (Igeo) of trace elements for this study indicated that the study area is strongly contaminated with Cd and Co. Generally, the finding of this research showed that Huangpi soil is contaminated.
