“…and Populus spp. can phytoremediate Cd, Zn, Cu, and Cr ; and Pinus sylvestris for the accumulation of Cu, Cr, Pb, and Ni . For the two metals in this study, it is known that Cr tends to be held in plant roots, whether supplied as Cr(VI) or Cr(III) and lead as Pb 2+ is accumulated in roots while only a small fraction is translocated upward to the shoots .…”

“…The great mobility of this metal is due to some organic root exudates that can reduce and bind with Cr ions, thus increasing the solubility for root absorption . This is consistent with previous work undertaken with the related species A. glutinosa, where Cr is mostly present in the stem . However, we need to bear in mind that the ionic forms of chromium, Cr (III) and Cr (VI), can behave differently inside the plant tissues.…”

“…A previous study of the related species A. glutinosa reported the phytostabilization capacity for Cu, Zn, and Cd as it avoids metal uptake to the above ground tissue by keeping it in its roots . However, high transfer of metal in A. glutinosa from roots has been reported for Cr and Ni .…”

Metals are non‐biodegradable pollutants, with high environmental persistence that have great toxic effects for the environment and humans. Lead and chromium can be found in the banks of rivers contaminated by domestic and industrial discharges. A number of plants are able to remove metals from the ground and accumulate them in their inner tissues without producing phytotoxic effects. Alnus acuminata ssp. acuminata is a native tree species that can be found on the banks of the contaminated Bogota River and whose phytoremediation capacity for Pb and Cr is unknown. In the study, tree seedlings were irrigated with water from the upper, middle, and lower basin of the river for 4 months. Metal accumulation was measured in the roots, stem, leaves, and soil, and plant parameters such as height, number of leaves, and chlorophyll percentage were recorded. Pb was mainly accumulated in roots (135 mg/kg from upper basin treatment), whereas Cr was found in stems (71 mg/kg). There were no significant differences between treatment and control for any of the three parameters, meaning no toxicity effects were found. Therefore, A. acuminata ssp. acuminata is suggested as a suitable tree for metal phytoremediation along the banks of polluted rivers. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 942–948, 2016

This article analyses changes of morphological indicators of Rhus typhyna L. in roadside plantations in Pavlograd, Ukraine. Experimental plots were placed at a distance from 1 to 130 m from the road. The control group of plants was at a distance of 1500 m from the highway. The plants were measured for length and thickness of annual sprout, number of leaves on it, the content of chlorophyll in leaves and accumulation of cadmium and lead in the tissues of these organs. It was found that, compared to the relatively clean area, the greatest decrease in the length and thickness of the annual shoots of the trees in the plantations, was for those which were at a distance of one metre from the highway. The number of leaves on a one-year shoot was significantly decreased compared to controls at all sites except those situated at a distance of one hundred and thirty meters from the path of moving sources of pollution. We evaluated the impact of transport emissions on the assimilatory apparatus. Within the twenty-five meter zone, there was an increase in the area of the leaf. The assimilation surface area was significantly decreased relative to values in the conditionally clean area only in the plants growing at a distance from one to five meters from the road. We identified a negative effect of the ingredients of motor emissions on chlorophyll content in leaves. The amount of chlorophyll a decreased with decreasing distance from the plantation to the road within the forty-meter area. Changes in the content of chlorophyll b lacked a clear pattern. The concentration of this pigment increased compared with control in a five-meter area, at a distance of twenty five meters it significantly decreased and did not differ from the indicators in the relatively clean areas, which were growing at a distance of forty and one hundred and thirty meters from the road. The amount of chlorophyll a + b in the leaves decreased compared to the control. Lead accumulated in these plant organs in the fortymeter zone. The amount of cadmium in the tissues of the leaf was significantly higher than the control values on plots located at a distance of twenty five meters. The strongest negative effects of phytotoxicants on susceptible plants occurred in plantations in the five-meter zone, which led to deterioration of the decorative quality of the plants.

“…Baltrénaité et al (2012) proposed the use of dynamic factors to assess metal uptake and transfer in plants. Between the advantages of the proposed factors is the elimination of systematic errors of analysis and thus the improvement of precision and quality of evaluation.…”

The chelate assisted phytoremediation of polluted soils, based on the complexation of metals with chelators, can be a valuable green solution for agricultural soils decontamination. Copper is considered a hardly available and slowly translocating element, but the complexation may increase its bioavailability and translocation capacity, with benefits for soil phytoremediation. In our study, the ability of horse manure-a natural source of compounds which can act as chelators for enhancing the bioavailability and uptake of copper from contaminated soils-was investigated, by the use of white mustard (Sinapis alba) as the accumulator plant; the results were compared with those obtained for ethylenediaminetetraacetate, a synthetic chelator. The copper bioavailability, bioaccumulation, uptake, and thus the potential for phytoremediation of copper polluted soils, were estimated by translocation factor, bioaccumulation factor, and uptake coefficient. The results indicated that the use of horse manure as natural chelators source can improve the copper phytoextraction capacity, also having the advantage of an increase in biomass.
