      You can’t single out one chemical as being the most hazardous. All chemicals can be dangerous. How dangerous a chemical is, is dependent on how much (concentration), what other chemicals are around, how you handle it etc.

      “The dose makes the posion” – even water will kill you if you drink too much too quickly (Google the unfortunate case of Leah Betts to learn how). That said, certain chemicals are intrinsically more toxic than others with cyanide, arsenic and thallium being amongst our weakest links.
