ABSTRACT
Experimental investigations were conducted to evaluate the toxic effects of different arsenic (As) species such as arsenite (As(III)), arsenate (As(V)) and dimethylarsinic acid (DMA) on the growth of okra (Abelmoschus esculentus). The present study describes the changes in the growth, yield and accumulation characteristics of okra plants spiked with 20 and 50 mg kg(-1) of As(III), As(V) and DMA. As species negatively affected the yield and growth of the plant.The availability of arsenic compounds in the aerial parts decreased in the order As(V) > As(III) > DMA and in the roots observed as As(III) > As(V) > DMA. The results showed that except As(V), okra accumulated As(III) and DMA mainly in its roots with limited transport to shoots. Thus the plant has the capacity to tolerate As stress and can be considered as a resistive variety. The study also reveals that removal of As by boiling the vegetables with excess of water is not possible.
