Abstract:

This study revealed the effects of pyrophyllite ore materials on heavy metals mobility in soil plots located near the steel mill in Zenica (Bosnia and Herzegovina). The experiment was set up in a randomized block design with four pyrophyllite treatment rates i.e. 0, 200, 400 and 600 kg ha-1 in three replications. Analyses of the heavy metals (Cu, Zn, Mn, Ni, Cr, Pb, Cd) in soil and plant samples were performed using atomic absorption spectrophotometry. Pyrophyllite addition in soil was found to reduce the availability of all tested heavy metals in the studied soil. The pyrophyllite addition at a rate of 200 kg ha-1 reduced Mn, Cu and Zn available forms in soil by 11.1, 20.4 and 11.2%, respectively, compared with control. The pyrophyllite addition at higher rates i.e. 400 and 600 kg ha-1 had an even higher impact on the decrease in Mn and Zn mobility in studied soil in comparison with 200 kg ha-1. Additionally, these pyrophyllite rates have the ability to reduce Ni mobility in studied soil. The study also found a positive effect of all pyrophyllite treatments to reduce heavy metals accumulation in the leaves of potato grown on the studied soil. In sum, the results of this study indicate that pyrophyllite treatment could be an effective technique for improving the environmental quality of soils and alleviating the hazards of heavy metals to plants. However, further studies are necessary to confirm or denied this hypothesis.

Abstract:

Food exposure to heavy metals such as Pb, Cd, Cr, Ni, As, Zn, Cu and Fe is considered a risk to human health. This study analyzes the level of heavy metals in soil and delicious apple tissues (fruit, leaf, shoot) in three different rootstocks: mm106, m26 and m9 grown in the Obiliq region (considered as a polluted region). The data obtained from the Obiliq areas are compared with those grown in reference clear area. Individual soil samples were collected from each plant to assess metal content in the immediate plant environment. Samples of soil, fruit, leaf and shoot have been analyzed for heavy metals (Pb, Cd, Ni, As, Zn, Cu, Cr and Fe) using atomic absorption spectrophotometry (AAS).
The results indicated that the average concentrations of Pb, Cd, Ni, As, Zn, Cu, Cr and Fe in soil of Obiliq areas were 2.03, 0.15, 6.99, 12.4, nd, 12.3, 4.68, 5.32 mg kg-1 d.w. respectively. The concentration of metals in the apple tissue increased with the increase of heavy metals in soil from polluted area. The accumulation ratios of heavy metals were calculated to assess the potential health risks. The mean concentrations of the heavy metals in the soil were in order of magnitude Ni > Zn > Cr > Cu > Fe > Pb > Cd > As while that in the fruits of apple were in order of magnitude Cr > Fe > Cu > Ni > Pb > Zn > Cd > As; in the leaves were Fe > Zn > Cu > Cr > Pb > Ni > Cd > As; in shoots were Zn > Fe > Cu > Pb > Ni > Cr > Cd > As.
Mobility of heavy metals and potentially hazardous in studied lands threatens the quality of apple fruit consumption, with a real risk that these elements (Cd, Pb, Ni and Cr) can enter the food chain.
