“…Uptake and accumulation of Cr by various crops are well documented (Cervantes et al, 2001;Wallace et al, 1976). It is observed in the study that the concentration of Cr in plant samples is found to be highest in the roots samples 0.24 + 0.002 and 0.20 + 0.001 mg kg À 1 of carrot and onion, respectively, as a greater proportion accumulates in the root tissues (Kabata, 1980).…”

Two root crops: carrot (Daucus carota) and spring onion (Allium fistulosum) and soil samples were selected from the agricultural fields located near Islamabad, Pakistan to determine their elemental content. Field soil speciation of the two crops was also carried out to analyse the correlation of the elements in field crop and soil. Concentrations of selected elements were evaluated in the leaf, stem, root and flowering part of the crops using flame atomic absorption spectrophotometry. The results showed that elements are mostly concentrated in soil rather than crop parts following the sequence Zn4Cu4Pb4Ni4Cr4Cd. Furthermore, soil speciation showed that Ni and Cr are more prevalent in the Fe -Mn oxide fraction, Zn and Cd as the carbonate bound fraction and Cu is found in the organic bound form. However, concentrations of Pb are similar across the carbonate, Fe -Mn oxide and organic bound fractions. The highest average concentration of Zn is found as the carbonate bound fraction (2.09 AE 0.005 mg kg À 1 ) and Cu as the organic bound (1.51 AE 0.029 mg kg À 1 ) in soil samples taken from the agricultural field of Daucus carota.

“…The increased availability of Fe due to the lower soil pH, together with the higher availability of P in the PLN 4 P 2 K 2 and FMN 4 P 2 K 2 treatments than in the control and N 4 P 2 K 2 treatments, probably decreased Cr uptake, because Fe and P can act as Cr antagonists (Wallace et al 1976).…”

Little attention has been paid to the effect of long-term fertilizer application on concentrations of elements in grain of barley produced on the metal non-contaminated agricultural soil. In 2010, we analyzed yield and concentrations of elements in grain of spring barley in unfertilized control, mineral fertilizer application (N 4 P 2 K 2 -70, 60 and 100 kg N, P and K per ha) and combinations of farmyard manure or poultry litter with mineral fertilizer (FMN 4 P 2 K 2 and PLN 4 P 2 K 2 ) treatments in the Ruzyně Fertilizer Experiment established on Luvisol in 1955 in Prague (Czech Republic). The yield of grain ranged from 4.03 to 9.74 t/ha in the control and FMN 4 P 2 K 2 treatment. There was a positive effect of fertilizer application on concentrations of nitrogen, phosphorus and potassium, but no effect on concentrations of calcium and magnesium. With the exception of iron, concentrations of micro (copper and zinc) and risk elements (arsenic, cadmium, chromium, lead, manganese and nickel) were not significantly affected by the fertilizer treatments. Long-term use of organic and mineral fertilizers with appropriate application rates does not represent any risk for contamination of barley grain by risk elements on mineral rich and metal non-contaminated agricultural soils.

“…It is known that Cr may compete with Fe, S, and P for binding sites (Wallace et al 1976). However; Cr is a variable element and exists in valence states from ¡2 to C6 in nature (Ergul-Ulger et al 2014).…”

Following the rapid uptake of contaminants in the first few hours of exposure, plants typically attempt to cope with the toxic burden by releasing part of the sorbed material back into the environment. The present study investigates the general trends in the release profiles of different metal(loid)s in the aquatic macrophyte Lemna minor and details the correlations that exist between the release of metal(loid) species. Water samples with distinct contamination profiles were taken from Nil€ ufer River (Bursa, Turkey), Yeniça ga Lake (Bolu, Turkey), and Beyşehir Lake (Konya, Turkey) and used for release studies; 36 samples were tested in total. Accumulation and release profiles were monitored over five days for 11 metals and a metalloid ( Fe, 66 Zn, 68 Zn) and correlation, cluster and principal component analyses were employed to determine the factors that affect the release of these elements. Release profiles of the tested metal(loid)s were largely observed to be distinct; however, strong correlations have been observed between certain metal pairs (Cr/Ni, Cr/Cu, Zn/Ni) and principal component analysis was able to separate the metal(loid)s into three well-resolved groups based on their release.
