“…The relationship was not improved using multiple linear regression with the inclusion of other factors such as the amount of irrigation applied to the site or grain yield. This is in contrast with several studies that have shown that N fertilizer application can increase Cd uptake in wheat grain (Wångstrand et al, 2007;Li et al, 2011), likely through soil acidification, changes in ion exchange, and plant physiological processes.…”

Wheat (Triticum aestivum L.) grain is a contributing source of dietary Cd in New Zealand, but despite this, there is a dearth of information on Cd concentrations in wheat and the factors that affect uptake. We measured Cd concentrations in 12 wheat cultivars grown in field sites across New Zealand and also assessed the soil, plant, and crop factors that have been reported to affect Cd uptake. We found there was a wide range in grain Cd concentrations (0.004 to 0.205 mg kg−1 fresh weight [FW]). The overall mean concentration (0.066 mg kg−1 FW) was below the maximum limit (ML) of 0.1 mg kg−1 FW. Only 7% of grain samples across seven sites exceeded the ML. There were significant (P < 0.05) differences (2.5‐fold) in Cd concentrations in wheat grain between cultivars. No strong significant relationships were found between soil properties and Cd concentrations in grain. Further, management factors affecting grain Cd concentrations were inconsistent. Given the lack of relationships between soils and management practices, the most effective way of limiting Cd uptake in wheat grain at sites where Cd exceeds MLs may be the use of low‐Cd‐accumulating cultivars. Further studies are required to explore specifically the influence of irrigation and effects of type and rate of fertilizer on Cd uptake in wheat, as well as to better understand the mechanisms of Cd uptake in wheat. Core Ideas There was a 2.5‐fold range in Cd concentrations in grain among cultivars. No relationships were found between soil properties and Cd in grain. Overall Cd concentrations in wheat grain were below maximum limits. Using low‐Cd‐accumulating cultivars may be a strategy to limit uptake in grain.

“…The application of these fertilizers to the agricultural lands will lead to the accumulation of these metals in soil. Plants may absorb these metals when grown in contaminated soils (Chang et al 2014;Li et al 2011;Singh and Myhr 1998). …”

The levels of four metals (Zn, Cu, Cd, and Pb) were evaluated in two fruit types (apricot and fig), a fruity vegetable (tomato), and three leafy vegetables (arugula, spinach, and lettuce) that are commonly grown and consumed in Aseer Region, Saudi Arabia. Flame atomic absorption spectrophotometry was employed for quantification. The quality of results was checked by a certified reference material (NIST SRM 1570a). Good recovery values in the range of 87-104% were achieved. Metals were quantified in washed and unwashed samples to evaluate the effect of washing. Statistically, no significant difference was noticed (p>0.05), except for Zn in arugula and Cu in apricot and spinach. The levels of metals found in the analyzed fruits and vegetables were in their normal ranges in crops and not posing any serious risks to the consumers in Aseer Region. The toxic elements Pb and Cd were well below the maximum levels set in the Saudi and international food standards. Zn and Cu levels were comparable to the ranges reported in worldwide previous studies.

“…Uptake of Cd by wheat has been well documented, and variables controlling uptake are numerous (Gawalko et al, 2002;Franzen et al, 2006;Mitchell et al, 2000;Norvell et al, 2000;Weggler-Beaton et al, 2000;Wu et al, 2002). The main variables for increased Cd uptake are low soil pH and low soil organic matter, high soil Cd concentrations (Wu et al, 2002), N fertilizer applications (Li et al, 2011), and the presence of Cl salts (Norvell et al, 2000). The elevated Cd in the gypsum-treated plots may be a result of Cd being removed from the soil exchange sites by the oversaturation of Ca through gypsum applications.…”

The 11 major electricity-generating coal combustion stations in the northern Great Plains have the potential to produce almost 1 million Mg of flue gas desulfurization gypsum (FGDG) annually, which is a very attractive fertilizer (Ca and S) and amendment for sodic and acid soils. The potential environmental impacts of applying FGDG to soils in this region have not been fully investigated. The objectives of this research were to determine the influence of FGDG on soil chemical characteristics and to determine the impact that FGDG has on hard red spring wheat ( L.) yields and element analysis of the grain. Flue gas desulfurization gypsum and commercial gypsum were applied at rates of 0, 2.24, 11.2, and 22.4 Mg ha to two soils in southwestern North Dakota in the spring of 2007. Soil and grain chemistries were monitored for two growing seasons. Wheat grain yields and elemental analysis of the grain were generally not affected by the gypsum treatments, indicating that the gypsum products did not negatively affect plant productivity. In addition, soil elemental analysis was similar across the treatments at both sites in both years. The results from this study indicate that its application to soil at rates used for sodic soil remediation (Mg ha) did not negatively affect the chemistries of either the soils or the wheat evaluated in this study compared with a commercial gypsum product or control soils.
