“…Our observations are in agreement with similar studies by Zheljazkov et al, (2006Zheljazkov et al, ( , 2008a, Kováčik et al, (2006) and Stancheva et al, (2010), on different aromatic plants and/or different contamination conditions. These groups also concluded that several aromatic plants they tested, either in pot experiments similar to ours (Zheljazkov et al, 2006), experiments with soil from contaminated fields (Zheljazkov et al, 2008b, Stancheva et al, 2010, or hydroponics experiment (Kováčik et al, 2006, Zheljazkov et al, 2008a) accumulated significant amounts of heavy metals, mainly in their root systems, with fractions of heavy metals to be found in the aboveground parts of the tested plants.…”

CULTIVATION OF MEDICINAL AND AROMATIC PLANTS IN HEAVY METAL-CONTAMINATED SOILSLYDAKIS-SIMANTIRIS N. ABSTRACTThe growing number of polluted land areas makes the question of rehabilitation and safe/effective use of these areas increasingly imperative. For land polluted by heavy metals, the possibility of transferring the toxic pollutants to humans through the food chain further increases the importance of the safe management of polluted lands. We examined the possibility of using heavy metal-polluted areas for growing specific aromatic plants, which can be used either as food herbs/infusions, or to produce high value products. In a pot experiment, chamomile, sage and thyme plants were exposed to a range of concentrations of Cd, Pb, and Ni in the soil. Toxic metal levels were determined in the roots, leaves and flowers (for chamomile) of the plants. All three plants accumulated relatively high amounts of metals in their roots, whereas the aboveground parts exhibited lower accumulation capacity. Regardless the levels of metal accumulation, the quality of essential oils from chamomile, sage, and thyme was not affected and in all cases the extracted essential oils were free of heavy metals. Our results suggest that the aromatic plants under study cannot be consumed either as food additives or as infusions. However, under strict control of the cultivations, heavy metal-contaminated areas can be used for the production of essential oils from aromatic plants.

“…As there were no changes on M. arvensis essential oil yield and composition, probably Pb and Cd applied in the soil was not sufficient to affect these routes of secondary metabolites production. Similarly, the exposition of Anethum graveolens and Ocimum basilicum to Cd, Pb and Cu showed no clear trend of variation (ZHELJAZKOV et al, 2006). Moreover, Mentha piperita cultivated with Pb and Cd, under maximum concentration of 100 and 1500ppm respectively, showed a significant reduction of essential oil yield, which was mainly associated with the reduction of biomass, number of leaves and total leaf area (AMIRMORADI et al, 2012).…”

“…Soils contaminated with this metal can cause severe reductions in crop productivity (SHARMA & DUBEY, 2005), affecting the essential oils production and composition (ZHELJAZKOV et al, 2006), besides promotes ultrastructural changes as chloroplast dilatation and membranes rupture (HU et al, 2007). Cd is considered a heavy metal found naturally in the soil by mineralization processes of some rocks, but it is widely released into the environment through waste incineration, urban traffic, phosphate fertilizers contamination, among others things.…”

Contamination of medicinal plants with heavy metals as Pb and Cd can affect the growth and the essential oil production of the plants and represent a risk to those who consume as medicine. This study aimed to evaluate the effects of absorption and localization of Pb and Cd on growth, ultrastructural aspects of leaves and essential oil yield and composition of Mentha arvensis,applied on the soil with increasing concentrations (8, 16, 32, 64 and 128mg kg -1 (8, 16, 32, 64 and 128mg kg -1

“…In Japan, the paddy fields that have produced rice grains containing cadmium at concentrations [1 lg g -1 are designated as contaminated paddy fields (Makino et al 2007). Zheljazkov et al (2006) found that there was no detectable cadmium, copper, or lead contents in the oils of dill (Anethum graveolens), peppermint (Mentha 9 piperita), or basil (Ocimum basilicum) that were grown in soils amended with these heavy metals with no alterations of oil composition. There was also no risk of transferring heavy metals to the oils of these crops.…”

“…Essential oil is used as an aromatic agent in several non-food industries as a highvalue product (Zheljazkov et al 2008a). Some aromatic crops can accumulate cadmium, copper, and lead, but these heavy metals do not pass from plant tissues to the extracted essential oils (Zheljazkov et al 2006). Thus, this plant could be grown safely as a cash crop in cadmium-polluted soil without cadmium contamination in its essential oil.…”

A field study of cadmium phytoremediation by Ocimum gratissimum L. and the potential enhancement by two cadmium-resistant bacteria, Ralstonia sp. TISTR 2219 and Arthrobacter sp. TISTR 2220, were explored in a cadmium-polluted agricultural area. The results demonstrated the ability of one of the bacterial strains to promote cadmium accumulation in O. gratissimum L. planted in soil with cadmium concentrations till 65.2 mg kg -1 . After transplantation in contaminated soil for 2 months, soil inoculation with Arthrobacter sp. enhanced cadmium accumulation in the roots, above-ground tissues, and whole plant of O. gratissimum L. by 1.2-fold, 1.4-fold, and 1.1-fold, respectively, compared with the untreated control. The presence of Arthrobacter sp. in soil facilitated cadmium phytoremediation in O. gratissimum L. similar to that of an EDTA application. Seeds of O. gratissimum L. grown in polluted soil contained undetectable to negligible concentrations of cadmium. Significant increases in the bioconcentration and translocation factors of O. gratissimum L. were observed in Arthrobacter sp.-inoculated plants at only 2 months post-transplant compared with the uninoculated control. The highest percentage of cadmium removal was found in soil used to cultivate EDTA-treated O. gratissimum L., followed by an Arthrobacter sp.-inoculated plant. Our findings suggest that the synergistic use of Arthrobacter sp. with O. gratissimum L., an essential oil-producing crop, could be a feasible economic and environmental option for the reclamation of cadmiumpolluted areas.
