“…After harvest, the soil in each pot was mixed and subsamples were collected for analysis of extractable Pb and As, pH, and salinity. Soil Pb and As were measured in the filtered extract of a 1 soil : 10 concentrated HCl suspension shaken for 60 rein; this procedure was a modified version of those described in Benson (1976) and Veneman et al (1982). This procedure is used in Washington to estimate potential for soil As phytotoxicity in fruit trees (Dow et al, 1983).…”

Phosphate fertilizer additions to soils containing lead arsenate (LA) pesticide residues can increase As volubility. Apricot (Prunus armeniaca L.) rootstock liners were grown in nondraining pots containing Burch loam soil that received a factorial treatment combination: 1) LA enrichment [no added LA (-LA), and LA added at 138 mg Pb/kg and 50 mg As/kg (+LA)]; 2) fertilizer type [monoammonium phosphate (MAP) and its sulfur analog ammonium hydrogen sulfate (AHS)]; and 3) fertilizer anion rate (0-26.1 mol/m3 soil). Measured response variables were soil salinity and pH, plant biomass, and plant As and Pb concentrations. Both MAP and AHS increased soil electrical conductivity (EC) and decreased soil pH, with AHS usually being more salinizing and acidifying than MAP was at equivalent rates. Adding LA reduced shoot and root mass and increased As and Pb concentration in shoots and roots. Shoot and root mass were inversely related to soil EC in the -LA soil but not in the +LA soil. Adding MAP increased shoot and root As concentration in the +LA soil, but adding AHS had no effect. Fertilizer type and rate did not influence shoot As concentration or root Pb concentration in the -LA soil or shoot Pb concentration in either the +LA or -LA soil. Adding AHS to the +LA soil increased root Pb concentration. These results are consistent with a P-enhanced solid-phase As release mechanism, which consequently increases plant uptake of soil As. Phosphate amendment had no effect on soil Pb phytoavailability.

“…Soil texture was measured with a micropipette method (Miller and Miller, 1987) and pH in 1:1 soil and distilled water. Total soil Pb concentration was estimated with concentrated HCl extraction (Veneman et al, 1982) and assay by flame atomic absorption spectrophotometry. Available soil P concentration was measured by 0.5 M NaHCO 3 (pH 8.5) extraction and assayed colorimetrically by the modified ascorbic acid method (Kuo, 1996) after eliminating AsO 4 interference (USEPA, 1983, p. 365.3‐1 to 365.3‐4).…”

Antimony Impurity in Lead Arsenate Insecticide Enhances the Antimony Content of Old Orchard Soils

Lead arsenate was a commonly used insecticide during the first half of the 20th century, particularly in deciduous tree fruit orchards. Antimony is cotransported with As during the ore refining process and could occur as an impurity in commercial lead arsenate products. The total concentrations of As and Sb in eight soil samples collected from eight orchards located throughout central Washington State were analyzed by neutron activation analysis. Total soil Sb concentrations ranged between 0.4 and 1.5 mg kg(-1), while total soil As concentration ranged from 1 to 170 mg kg(-1). Total soil Sb and As concentrations were positively related. Total Pb and As concentrations in four of the soils were substantially higher than natural background, while the Sb to As concentration ratios in these soils were consistent with values measured in three lead arsenate insecticide products. These results confirm that Sb impurity is present in lead arsenate insecticide and has contributed to Sb enrichment of soils on which lead arsenate-treated plants were grown. Although higher than in uncontaminated soils from the same region, the Sb concentrations in the affected soils fall within the normal range observed worldwide and are substantially lower than values associated with impaired human or environmental health.
