“…DTPA-extractable proportion of heavy metals pseudo-total concentration decreases in order Cu > Pb > Zn > Ni > Co, while DTPA extractable Cr was under the detection limit (0.007 μg Cr/ml). A very low phytoavailable proportion of pseudo total content was found in all samples for Ni (0.23%), Zn (0.51%) and Co (0.05%), possibly influenced by relatively high pH (>6.5) [40] and high organic content (2.98%) [41], while Cu and Pb had considerably higher available amounts (2.53 and 2.39%, respectively). However, positive correlation between pseudo-total and available amounts of heavy metals in soil was not found.…”

This experiment investigated mineral composition of 13 basil genotypes (Ocimum spp.) in order to find varieties supporting human dietary intake of essential minerals and to evaluate basil genotypes which could serve for herbal production as raw material in pharmaceutical or food processing industry. In addition, this study tested a potential risk of the accumulation of heavy metals during the commercial production of basil on agricultural soil. Mineral composition of basil genotypes was found to be in association with its genetic potential, where some of them can be used in human nutrition as an additional source of several minerals, particularly micronutrients (Fe, Mn and Zn), which generally improve human immune system. Iron-rich basil genotypes were identified in this experiment, like Compact (3576.0 mg/kg), with Lattuga (1585.6 mg/kg) and Blue spice (1167.9 mg/kg) genotypes, containing more than 1000 mg/kg of Fe in herbal part on dry basil (d.m.). This attract a special attention as a source of iron, especially for humans with low Fe intake, and consequently, for people with low level of hemoglobin. Basil grown on agricultural soil was tested on the accumulation of heavy metals (Cu, Co, Cu, Ni, Cr and Pb), which were not found to be excessive in herbal parts of the plants. Cluster analysis (CA) distinguished Ocmium spp. genotypes in two separate groups. Despite of significant differences among the genotypes, content of Fe, Mn, Co, Cr, Ni and Pb made a clear distinction between the clusters.

“…It can be seen from the Table I that the total Ni concentration is in the interval from 45 to 148 mg/kg. 9 Soil as an experimental factor also exerted a statistically significant influence on the uptake of Ni by maize roots. Maximum allowed Ni concentration in agricultural soils is 50 mg/kg.…”

Nickel is a non-essential element in the nutrition of the majority of plant species and can be toxic to plants when its concentration in soils is high. Several soil properties have an effect on the uptake of this heavy metal by plants. The purpose of this investigation was to determine the effect of fertilization, soil acidification and liming on the uptake of Ni by maize plants grown on some alluvial soils. A pot experiment with maize plants grown on soils having various properties and elevated content of Ni was set up. The experiment lasted six weeks. The roots and shoots were analyzed for the concentration of Ni. From the results of the experiment, it can be concluded that the roots had higher concentrations of Ni than the shoots. The addition of mineral fertilizers (without application of other measures) mainly decreased the concentration and uptake of Ni by the roots and the transport of Ni to the shoots. Soil acidification (to pH 4.5) caused an increase in the Ni concentration in the plants and in its removal from the soil. Liming of acid soils had a positive effect on the uptake of Ni by young maize plants. The obtained results are important from the standpoint of reducing the pollution of plants by potentially toxic heavy metals.

“…Moreover, soil treatments such as soil washing are detrimental for soil structure and properties. For these reasons, less expensive techniques have been researched and developed including in situ remediation using limestone and Mn fertilizer (Siebielec et al 2007) and phytoextraction. Phytoextraction is capable of removing soil Ni if the chemical forms present in the contaminated soil can be dissolved and accumulated by hyperaccumulator plant roots ).…”

To determine if the Ni-hyperaccumulator Alyssum corsicum can absorb Ni from the kinetically inert crystalline mineral NiO(s) (bunsenite). A. corsicum and A. montanum plants were grown for 30 days in a serpentine Hoagland solution. NiO was provided at 0 or 0.1 g L −1 (1.34 mmol L −1 ) as reagent grade NiO particles <1 μm diameter, continuously mixed by aeration. A. corsicum and A. montanum shoots contained 19.4 and 5.2 mg Ni kg −1 DW with NiO, and 3.0 and 1.1 mg Ni kg −1 DW shoots, respectively in the control treatment. A. corsicum normally absorbs over 12,000 mg Ni kg −1 shoots when supplied 300 μM soluble Ni. Roots were coated with the NiO particles and contained 3-5% Ni at harvest. Despite the small Ni accumulation in the NiO treatment above control, A. corsicum is not capable of dissolving and hyperaccumulating Ni from NiO.
