The accumulation and transformation of arsenic species have been studied in the context of hydroponic cultivation of strawberry plants. Cultivation experiments have been performed by adding inorganic arsenic at concentrations of 10, 100 and 1000 µg L-1 via root irrigation. The total arsenic content was determined by Hydride Generation-Atomic Fluorescence Spectrometry (HG-AFS). The accumulation was dependent on the concentration of arsenic added to the irrigation and the arsenic species. Arsenic (III) accumulated at higher rates than arsenic (V). A greater accumulation of arsenic was found in roots (0.44-4.10 mg kg-1) than in stems (0.43-1.27 mg kg-1) and fruits (0.22-0.30 mg kg-1). The speciation results obtained by HPLC-HG-AFS analysis indicated that the addition of As(III) resulted in a partial methylation producing monomethyl arsenic (MMA) and dimethyl arsenic (DMA). After As(V) addition, only MMA was observed and this was accompanied with a notable reduction in the ratio of As(V) to As(III).

富含无机砷的灌溉条件下草莓植株中的砷积累和形态形成。

在草莓水培栽培中研究了砷物质的积累和转化。通过根灌添加10、100和1000 µg L-1的无机砷进行了培养实验。总砷含量通过氢化物发生-原子荧光光谱法（HG-AFS）测定。累积量取决于灌溉中添加的砷浓度和砷种类。砷（III）的积累速率高于砷（V）。在根部（0.44-4.10 mg kg-1）比茎部（0.43-1.27 mg kg-1）和果实（0.22-0.30 mg kg-1）中砷的积累量更大。通过HPLC-HG-AFS分析获得的物种形成结果表明，添加As（III）导致部分甲基化，从而产生单甲基砷（MMA）和二甲基砷（DMA）。添加As（V）后，仅观察到MMA，并且As（V）与As（III）的比例显着降低。
