Whenever I think of arsenic, an old movie, "Arsenic and Old Lace", comes to mind. In this famous movie, two old ladies doctor refreshments with arsenic to kill off lonely old men. (This creepy plot, of course, comes with many laughs at the antics of Cary Grant.) Arsenic poisoning is serious. While we know that high amounts cause death, low exposure can still cause many health issues and problems. Besides the obvious and more well known problems caused by arsenic poisoning, there are potential problems for those exposed to arsenic over a long length of time.
