Effect of arsenite, arsenate and dimethylarsinic acid (DMA) on the growth of seedling plants were investigated in order to compare the toxicity of arsenic species in soil environments. Test plants were mung bean (Phaseolus radiatus), wheat (Triticum aestivum), barely (Hordeum vulgare), cucumber (Cucumis sativus L.). Seedling growth in As-contaminated soil were significantly reduced in all test species. Arsenite was more toxic than arsenate and DMA. Among the test plants, mung bean was most sensitive to arsenic, followed by cucumber, wheat, and barely.
