“…The contents of heavy metals in plant products for human nutrition or in fodder plants are important for the quality of the harvest [87][88][89][90][91][92][93][94][95][96][97][98]. It must be distinguished between seed/grain crops such as cereals or soybean and plants of which the whole shoot is harvested such as plants used for silage or grasslands.…”

“…Elevated contents of heavy metals-especially of pollutants such as Cd, Cr or Pb-can also decrease the quality of harvested plant products [92][93][94][95][96][97][98]. Undesirably high or even toxic levels are a rather local, but nevertheless an important problem.…”

“…Low uptake rates for the pollutant(s), a slow root-to-shoot transfer and a minimized redistribution to harvested shoot parts is desirable for crops grown on polluted soil. Contaminated irrigation water, the use of sewage sludge for fertilization, the release of pollutants from industrial processes and an improved solubilization of some heavy metals under extreme climatic conditions (e.g., flooding) may cause undesirably high concentrations in plant products [93][94][95][96][97][98]. Even when the input of heavy metals in contaminated soil is drastically lowered, fields may still contain high heavy metal contents for decades.…”

Heavy Metals in Crop Plants: Transport and Redistribution Processes on the Whole Plant Level

Abstract:Copper, zinc, manganese, iron, nickel and molybdenum are essential micronutrients for plants. However, when present in excess they may damage the plant or decrease the quality of harvested plant products. Some other heavy metals such as cadmium, lead or mercury are not needed by plants and represent pollutants. The uptake into the roots, the loading into the xylem, the acropetal transport to the shoot with the transpiration stream and the further redistribution in the phloem are crucial for the distribution in aerial plant parts. This review is focused on long-distance transport of heavy metals via xylem and phloem and on interactions between the two transport systems. Phloem transport is the basis for the redistribution within the shoot and for the accumulation in fruits and seeds. Solutes may be transferred from the xylem to the phloem (e.g., in the small bundles in stems of cereals, in minor leaf veins). Nickel is highly phloem-mobile and directed to expanding plant parts. Zinc and to a lesser degree also cadmium are also mobile in the phloem and accumulate in meristems (root tips, shoot apex, axillary buds). Iron and manganese are characterized by poor phloem mobility and are retained in older leaves.

Soil is composed of different types of particles which are either natural or of anthropogenic origin. Anthropogenic particles are often related to the presence of heavy metals and thus provide information on soil quality. Magnetic parameters can detect the presence of such particles and may be used as a proxy for environmental pollution. This study explores the relationships between magnetic particles and the nematofauna of agricultural soils. Magnetic, pedological, microscopy and nematological analyses were conducted in soils collected from major regions of potato production in Portugal. The magnetic characterisation of soils identified regions with magnetic particles with possible anthropogenic origin. Microscopy analysis revealed the presence of spherical particles dominantly composed of Fe, O and C. A positive and significant relationship was found between saturation isothermal remanent magnetisation (SIRM) and mass-specific susceptibility (χ), confirming the importance the ferrimagnetic fraction to magnetic properties. The nematode communities were composed of nematodes belonging to four trophic groups (bacterial feeding, plant feeders, fungal feeders and omnivores/predators). The relationships between magnetic parameters and the nematodes showed that (1) S −25 has a linear correlation with number of nematodes per kilogram of soil and with plant feeders' trophic group and (2) SIRM correlates with the bacterial feeders trophic group. This study reveals that magnetic proxies may provide means for detecting regions with higher levels of pollution, possibly related to heavy metals. Due to the large background variability found in magnetic parameters, the sampling spacial mesh should to be further refined and the input of magnetic minerals needs to be locally calibrated.

“…Heavy metals are very persistent in the environment, they do not biodegrade or thermodegrade, and they accumulate to toxic levels. The cross-contamination of food by Ni and Cr is an emerging nutritional hazard [8]. Although Ni is an essential metal and plays important roles in plant metabolism, Ni toxicity has become of particular concern due to its increased industrial use [9].…”

The water aquifers of the regions of Asopos River in Viotia and Messapia in Evia (Greece) have been contaminated with hexavalent chromium (Cr (VI)) and bivalent nickel (Ni (II)). Given that these areas are the two biggest tuber producing regions of Greece, in our previous work, the cross-contamination of the food chain with these two heavy metals was quantified. In the present study, the potential of sunflower (Helianthus annuus) cultivation in these regions is evaluated. The scope of our study was to investigate the uptake of chromium and nickel by sunflower, in a greenhouse experiment. The study included two cultivation periods of plants in six irrigation lines with different levels of Cr (VI) and Ni (II) ranging from 0 μg/L (control) to 10,000 μg/L. In all plant parts, statistically significant increased levels of Cr (VI) and Ni (II) were found when compared to control ones. Also, a positive correlation, both for Cr and Ni, between levels of heavy metals in irrigation water and plants was observed. Following European Food Safety Authority recommendations, the obtained oil was evaluated as safe for consumption, therefore, sunflower cultivation could be a valid bioremediation solution for the Asopos and Messapia regions.
