Arsenic - SourceWatchArsenic is a naturally occurring element found in earth's crust. It is an odorless and tasteless semi-metal element. In the Periodic Table, its symbol is As and its atomic number is 33. Although arsenic is toxic to humans, it is used in a number of industries and released into the environment.
Arsenic Uptake in Plants - Bethel CollegeArsenic at a 67 ppm contamination level was toxic to the plants. Therefore phytoremediation of arsenic at this level and above using the plants tested, is not a viable solution. At 40 ppm, only the carrot, corn, and radish plants appeared uninterrupted in their growth.
