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).engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Strawberry plantsIrrigationArsenic SpeciationFruitsHPLC-HG-AFSjournal article10.1016/j.foodchem.2020.126215open access2301 Química Analítica
