What is arsenic? Arsenic is a chemical found naturally in soils, rocks, and water. There are 2 types: organic arsenic, which is found in fish and shellfish; inorganic arsenic, which is found in minerals, rocks, and mine tailings. Both types can be toxic at high levels. But inorganic arsenic is much more toxic. Environments with higher arsenic ...

This is due to rice's ability to take up arsenic from soil and water. Rice is also typically grown under flooded conditions, which increases the potential for arsenic uptake [FDA 2020]. Other plant species take up comparatively low levels of arsenic, even when grown in highly polluted soil or soil naturally high in arsenic. ...
