“…Similar results were found for the 0.54% Fe oxides treatment in the present work: although lettuce yield was little changed, the As concentration (and thus uptake) was reduced by 76%. Therefore, the application of FeSO 4 was effective in reducing As bioavailability, in line with the early reports on remediation of phytotoxicity (Vandecaveye et al, 1936; Thompson and Batjer, 1950) and recent laboratory studies of As solubility in response to added FeSO 4 (Moore et al, 2000). Therefore, FeSO 4 can be used to remediate soil containing old smelter residues as well as residues of a soluble source (lead arsenate) used as a pesticide.…”

“…However, this solidification treatment with cement makes the soil unsuitable for growing plants. Phytotoxic effects suffered by crops grown on soil with residues of lead arsenate insecticide could be corrected by applying FeSO 4 alone to the soil (Vandecaveye et al, 1936; Thompson and Batjer, 1950). However, there have been no recent bioassays of the effectiveness of Fe oxides or FeSO 4 in reducing As uptake by crops and probably none for contamination sources other than pesticides.…”

The redox was applied to soil contaminated by effluents from a potential of the As(V)/As(III) couple falls within the timber treatment plant, and the As in soil solution redynamic range of values that may be observed in sediduced from 3802 to 0.64 g L Ϫ1 ( Thompson and Batjer, 1950). However, in the numerically corresponding level of Fe oxides treatment.…”

Soil contamination by arsenic (As) presents a hazard in many countries and there is a need for techniques to minimize As uptake by plants. A proposed in situ remediation method was tested by growing lettuce (Lactuca sativa L. cv. Kermit) in a greenhouse pot experiment on soil that contained 577 mg As kg(-1), taken from a former As smelter site. All combinations of iron (Fe) oxides, at concentrations of 0.00, 0.22, 0.54, and 1.09% (w/w), and lime, at concentrations of 0.00, 0.27, 0.68, and 1.36% (w/w), were tested in a factorial design. To create the treatments, field-moist soil, commercial-grade FeSO4, and ground agricultural lime were mixed and stored for one week, allowing Fe oxides to precipitate. Iron oxides gave highly significant (P < 0.001) reductions in lettuce As concentrations, down to 11% of the lettuce As concentration for untreated soil. For the Fe oxides and lime treatment combinations where soil pH was maintained nearly constant, the lettuce As concentration declined in an exponential relationship with increasing FeSO4 application rate and lettuce yield was almost unchanged. Iron oxides applied at a concentration of 1.09% did not give significantly lower lettuce As concentrations than the 0.54% treatment. Simultaneous addition of lime with FeSO4, was essential. Ferrous sulfate with insufficient lime lowered soil pH and caused mobilization of Al, Ba, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, and Zn. At the highest Fe oxide to lime ratios, Mn toxicity caused severe yield loss.

“…The observed antagonistic effect of As on Zn absorption may have been another factor related to the consistent negative effect of solution MMAA on plant growth. A similar antagonistic MMAA-Zn interaction was observed before in rice (Marin, 1989;Oh and Sedberry, 1974) and in peaches (Batjer and Benson, 1958;Thompson and Batjer, 1950). Besides Zn, addition of MMAA also influenced Cu solubility in the soil.…”

Arsenic absorption by rice (Oryza sativa, L.) in relation to As chemical form present in soil solution was examined. Rice plants were grown in soil suspensions equilibrated under selected conditions of redox and pH, affecting arsenic solubility and speciation. A decrease in pH led to higher dissolved arsenic concentrations. When the soil redox potential dropped below 0 mV, most of the arsenic was present as As(Ill). Under more oxidizing conditions both As(Ill) and As(V) are present. Chemical speciation of As in the watersoluble fraction affected its phytoavailability. Most indigenous arsenic taken up by the plants remained in the root. Plant arsenic availability increased with increasing arsenic concentration in solution (lower soil pH) and with increasing amounts of soluble As(Ill) (lower soil redox). We also studied the uptake of monomethyl arsenic acid (MMAA), a widely used defoliant and herbicide, as affected by soil redox-pH condition. Amended MMAA was approximately two times more phytoavailable than the indigenous inorganic As forms and increased with decreasing pH and redox.

“…Because excessive arsenic in some fruit trees induces zinc deficiency, foliar sprays of zinc sulfate or zinc chelates have in some cases helped to overcome arsenic toxicity. Concurrent high nitrogen applications to the soil also were beneficial (40)(41)(42).…”

Inorganic arsenicals have been used in agriculture as pesticides or defoliants for many years and, in localized areas, oxides of arsenic have contaminated soils as a result of fallout from ore-smelting operations and coal-fired power plants. Use of inorganic arsenicals is no longer permitted in most agricultural operations, and recent air pollution controls have markedly reduced contamination from smelters. Thus, this paper will concentrate on the effect of past applications on arsenic accumulation in soil, phytotoxicity to and uptake by plants as influenced by soil properties, and alleviation of the deleterious effects of arsenic.Once incorporated into the soil, inorganic arsenical pesticides and arsenic oxides revert to arsenates, except where the soil is under reducing conditions. The arsenate ion has properties similar to that of orthophosphate, and is readily sorbed by iron and aluminum components. This reaction greatly restricts the downward movement (leaching) of arsenic in soils and the availability of arsenic to plants.Several methods of estimating plant available arsenic in soils have been developed. They involve extraction of the soil with reagents used to estimate phosphorus availability. This extractable arsenic is reasonably well correlated with reduced plant growth by, and plant uptake of arsenic. For most plants, levels of arsenic in the edible portion of the plant are well below the critical concentration for animal or human consumption, even when severe phytotoxicity occurs.Alleviation of arsenic phytotoxicity has been attempted by increasing the soil pH, by use of iron or aluminum sulfate, by desorbing arsenate with phosphate and subsequent leaching, and by cultural practices such as deep plowing. Only limited benefits have accrued from these procedures the cost of which is often prohibitively high. Since attempts to reduce arsenic toxicity have not been very successful, its excessive accumulation in soils should be avoided.
