“…Sorghum was able to take F from the substrate, so that not only could it be planted on soils with high F content but also would have potential properties to act as a bio‐remediator of these soils, which could be rotated between crops most affected with F as maize and soybeans. Several screenings of areas rich in F are conducted to find vegetables resistant to F so as to be used as phyto‐remediators . These results could be due to the different susceptibility of the crops to F, so that some plants would be resistant while others sensitive to F action.…”

“…Several screenings of areas rich in F are conducted to find vegetables resistant to F so as to be used as phyto-remediators. 29 These results could be due to the different susceptibility of the crops to F, so that some plants would be resistant while others sensitive to F action. Some works demonstrated that strains of mice that accumulate more F in bone and have higher circulating F levels are also resistant to the effects of F. 30 Furthermore, we found that the higher the amount of F in the substrate the lower the number of seeds germinated of maize and soybeans.…”

“…It was shown that 210 and 316 μM F accelerate As (III) and As (V) uptake by Pteris vittata in hydroponic cultures (Zhao et al 2015). Thus, P. vittata may be a suitable candidate for cleaning up the groundwater contaminated with both As and F. Boukhris et al (2015) identified three perennials Rhanterium suaveolens, Atractylis serratuloides, and Erodium glaucophyllum, which are in situ phytoremediators on arid F polluted soils. Three semi-arid species, Acacia tortilis, Cassia fistula, and Prosopis juliflora were grown in 10, 20, and 50 mg(F) kg -1 (d.m.)…”

Fluorine, one of the most abundant elements found on earth, acts as an environmental xenobiotics even at sparingly low concentrations. Uncontrolled anthropogenic activities have steeply increased the F content in the air, water, and soil. Irrigation of crops and vegetables with F contaminated groundwater or agricultural practices in contaminated soils adversely affect their physiological and biochemical parameters, leading to inhibited growth and productivity. Some plants can translocate the toxic ions from roots to shoots and accumulate them in the edible parts. Bioaccumulations of F have hazardous outcomes, as their concentrations in edible parts can be higher than the safe value. Screening of F hyperaccumulators and F-tolerant plants has been performed to facilitate phytoremediation. Some plant bioindicators have been identified which can be used to analyse the extent of atmospheric F pollution. Cumulative use of these organisms through proper scientific planning programs can potentially improve the agricultural soil quality in terms of their toxic F content. Future research should focus on proper execution of these phytoremediative strategies via robust field trials. High throughput genetic analyses should also be performed to identify quantitative trait loci which can be exploited to generate F-tolerant characters in susceptible crop cultivars.

“…This apparent discrepancy may originate from the fact that we estimated the Ni and Zn accumulation level in each plant organ by multiplying the concentrations per their respective dry masses. It is well known that pioneer tree species have a greater potential for absorbing heavy metals from the soil because they have higher photosynthetic rates and faster growth than non-pioneer species (Boukhris et al, 2016;Favaretto et al, 2011;Porte et al, 2010). However, our second hypothesis could be evaluated more precisely by estimating absolute concentration ratios between the values obtained in plants grown in the treatments with metal addition and the basal contents determined in plants grown in the control treatment (TNi/TC; TZn/TC; TNiZn /TC).…”

Background and aimsThe Brazilian Atlantic forest has been affected by the deposition of Ni and Zn, among other heavy metals adsorbed from atmospheric particles, which can be incorporated into the soil. If available in the soil, they can be absorbed by plant roots. The study aimed at testing experimentally the hypotheses: 1) Ni and Zn depositions increase their bioavailable fractions in the soil; 2) pioneer tree species demonstrate a greater potential to absorb Ni and Zn from the soil and less growth changes than non-pioneer species.MethodsThe experiment was carried out with six pioneer and non-pioneer species native to the Atlantic Forest, grown for 90 days in soil from an urban fragment of the Atlantic Forest, according to the treatments: soil with balanced fertilization (control) and soil enriched with Ni, Zn and Ni+Zn. At the end, the concentrations of Ni and Zn were determined in four soil fractions (F1: soluble; F2: linked oxides/hydroxides; F3: organic matter: F4: residual metals) and in leaves, stems/branches and roots. Mobility factors in soil, concentration ratios between treatments and respective controls, translocation index and relative growth rate in height, leaf number and total biomass were also calculated.ResultsThe results showed that Ni and Zn concentrations increased significantly in the bioavailable soil fractions (F1, F2). The absolute content of Ni and Zn in the plants directly reflected the soil level in the available forms.ConclusionsThe metal accumulation in the species occurred regardless of the successional group to which they belonged. Non-pioneer species showed greater susceptibility to the metals.
