“…It can be seen that the concentrations of four heavy metals in any part of spring wheat from five planting densities are all below the thresholds of plant toxicity [3]. Zn has the highest concentration followed by Cu, and they are two or more times higher than Pb and Cd, which may be due to the essentiality of Cu and Zn for plant physiology, while Pb and Cd are the stress factors to photosynthesis, chlorophyll synthesis and antioxidant enzymes metabolism [15,16].…”

In order to investigate the effects of planting density on accumulation of heavy metals in spring wheat, a weak alkaline agricultural district mainly contaminated by heavy metals Cu, Zn, Pb and Cd, was chosen in 2014. Five planting densities (114×10 4 , 174×10 4 , 249×10 4 , 369×10 4 and 519×10 4 plants hectare -1 , respectively) were designed and the level of heavy metals in soil and in various parts (root, stem, leaf, husk and grain) of spring wheat were detected, and then the health risk to human health was assessed via hazard quotient. The results indicate that concentrations of Pb and Cd in each part of spring wheat plant are negatively correlated with planting density, similar but weaker trends are observed for those of Cu and Zn. The hazard quotient of heavy metals through food chain is markedly reduced with increasing planting density, especially for Pb and Cd at higher planting densities (369×10 4 and 519×10 4 plants hectare -1 ). Conclusively, the present study shows that suitable planting density could be a feasible cultivation method for ensuring the safety of wheat products and human health on slightly polluted alkaline soils.

“…In wheat grown on Tunisian mine tailings, soil, shoot, and grain concentrations varied by 27, 49, and 13× in Pb, respectively; 420, 43, and 30× in Cd, respectively; and 97, 35, and 2.4× in Zn, respectively [83]. The field pea cv.…”

“…The concentrations predominantly rising in the upper shoot were once more dramatically down-or up-regulated at the extremely versatile rachis/grain interface in more or less successful attempts to realize the inherent seed target metallome of the cultivar [19][20][21]72]. Unlike the herbage, grains respond least to changes in agronomic conditions and the supply with soil minerals [83][84][85] and nitrogen [18,23], and they stabilize their metallome inherently in a narrow range [21,23,27]. This was also reported for the Fe and Zn content of soybean [22], rice [21], and pea plants [20], although the respective concentrations in vegetative tissues rose drastically.…”

Abstract:Testing the quality of heavy-metal (HM) excluder plants from non-remediable metalliferous soils could help to meet the growing demands for food, forage, and industrial crops. Field cultures of the winter wheat cv. JB Asano were therefore established on re-cultivated uranium mine soil (A) and the adjacent non-contaminated soil (C). Twenty elements were determined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) from soils and plant sections of post-winter seedlings, anthesis-state, and mature plants to record within-plant levels of essential and toxic minerals during ripening and to estimate the (re)use of the soil-A herbage in husbandry and in HM-sensitive fermentations. Non-permissible HM loads (mg·kg −1 ·DW) of soil A in Cd, Cu, and Zn of 40.4, 261, and 2890, respectively, initiated the corresponding phytotoxic concentrations in roots and of Zn in shoots from the seedling state to maturity as well as of Cd in the foliage of seedlings. At anthesis, shoot concentrations in Ca, Cd, Fe, Mg, Mn, and Zn and in As, Cr, Pb, and U had fallen to a mean of 20% to increase to 46% during maturation. The respective shoot concentrations in C-grown plants diminished from anthesis (50%) to maturity (27%). They were drastically up/down-regulated at the rachis-grain interface to compose the genetically determined metallome of the grain during mineral relocations from adjacent sink tissues. Soil A caused yield losses of straw and grain down to 47.7% and 39.5%, respectively. Nevertheless, pronounced HM excluder properties made Cd concentrations of 1.6-3.08 in straw and 1.2 in grains the only factors that violated hygiene guidelines of forage (1). It is estimated that grains and the less-contaminated green herbage from soil A may serve as forage supplement. Applying soil A grains up to 3 and 12 in Cd and Cu, respectively, and the mature straw as bioenergy feedstock could impair the efficacy of ethanol fermentation by Saccharomyces cerevisiae.

“…(3) The abandoned tailing dams without implementing a protection system, the natural spread of tailing by wind, water and rainfall results in the contamination of adjacent soils: Wind transport of tailings may be another important factor influencing the spreading of pollution, as has been reported by several authors for pollution distribution from minning area [13,34,35,36,37]. Furthermore, in semi arid environments, aeolian erosion is the dominant natural means of pollution by tailing mine spread to agricultural adjacent soils.…”
