If a large amount of arsenic is swallowed by humans, in a form that is readily absorbed, it can cause rapid poisoning and death. The gut, the heart and the nervous system are affected.
More studies supported that the synergistic effect between As and Se toxicity. For example, Spallholz (2004) found that high levels of chronic ingestion of arsenic cause Se being more toxic and carcinogenic over time. Huang et al. (2008) reported that long-term exposure to arsenic enhances Se toxicity even at low arsenic exposure levels.
