Barium toxicity in plants

The effect of organic matter addition on Ba availability toHelianthus annuusL.,Raphanus sativusL., andRicinus communisL. grown on a Neossolo Litólico Chernossólico fragmentário (pH 7.5), contaminated with scrap residue was evaluated. Four rates (0, 20, 40, and 80 Mg ha−1, organic carbon basis) of peat or sugar cane filter, with three replicates, were tested. Plant species were grown until the flowering stage. No effect of organic matter addition to soil on dry matter yield of oilseed radish shoots was observed, but there was an increase in sunflower and castor oil plant shoots when sugar cane filter cake was used. The average Ba transferred from roots to shoots was more than 89% for oilseed radish, 71% for castor oil plants, and 59% for sunflowers. Organic matter treatments were not efficient in reducing Ba availability due to soil liming.

“…When larger amounts are accumulated this element can be toxic inhibiting plant growth (Chaudhry et al, 1977;Llugany et al, 2000;Kuperman et al, 2006). Also, in animals and men, the ingestion of Ba in soluble forms is highly toxic.…”

Barium salts are used extensively for industrial purposes, generating residues that, if not appropriately disposed, can increase soil Ba content. The aim of the present work was to evaluate Ba extraction potential of mustard (Brassica juncea Czern.), sunflower (Helianthus annuus L.), and castor bean (Ricinus communis L.), grown in a soil artificially contaminated with increasing Ba additions. A greenhouse experiment was carried out by adding BaSO 4 to a Rhodic Hapludox sample, at the 0, 150 and 300 mg kg -1 rates. After harvesting, the pot soil material was also analyzed for exchangeable Ba by CaCl 2 extraction and by an ion exchange resin method. None of the plant species tested presented toxicity symptoms, decreased nutrient accumulation or decreased dry matter production in response to Ba treatments. The accumulation of Ba, in decreasing capacity was: sunflower> mustard> castor bean. The largest accumulation was with sunflower at 300 mg kg -1 of Ba added to the soil. When evaluated by the transference factor, none of the species tested was an efficient Ba accumulator, up to 47 days after emergence. The ion exchange resin method was not adequate to evaluate Ba availability to these plants.

“…Barium (Ba), however, has been little studied in soils and plants, although Chaudhry et al (1977), Llugany et al (2000), Suwa et al (2008) and Monteiro et al (2011) report phytotoxicity when large amounts accumulate in plants. The chemical species of this element are highly influential on its availability in potentially "contaminated" soils, especially when the source of contamination is barite (BaSO 4 ), or there is sulfate present in the soils (Ippolito & Barbarick, 2006;Menzie et al, 2008).…”

SUMMARYPhytotoxicity and transfer of potentially toxic elements, such as cadmium (Cd) or barium (Ba), depend on the availability of these elements in soils and on the plant species exposed to them. With this study, we aimed to evaluate the effect of Cd and Ba application rates on yields of pea (Pisum sativum L.), sorghum (Sorghum bicolor L.), soybean (Glycine max L.), and maize (Zea mays L.) grown under greenhouse conditions in an Oxisol and an Entisol with contrasting physical and chemical properties, and to correlate the amount taken up by plants with extractants commonly used in routine soil analysis, along with transfer coefficients (Bioconcentration Factor and Transfer Factor) in different parts of the plants. Plants were harvested at flowering stage and measured for yield and Cd or Ba concentrations in leaves, stems, and roots. The amount of Cd accumulated in the plants was satisfactorily evaluated by both DTPA and Mehlich-3 (M-3). Mehlich-3 did not relate to Ba accumulated in plants, suggesting it should not be used to predict Ba availability. The transfer coefficients were specific to soils and plants and are therefore not recommended for direct use in risk assessment models without taking soil properties and group of plants into account.Index terms: soil pollution, transfer factor, bioconcentration factor.
