Если мышьяк, как химический элемент, то достаточно человеку проглотить ничтожную щепотку его оксида или один раз вдохнуть газообразный мышьяковистый водород, чтобы смертельно отравиться.А если мышьяк - как лекарство, то это вещество или его соединения (применяется как общеукрепляющее, противомикробное и т.п. средство)
