Frequent Questions

What is the difference between organic and inorganic arsenic?

Arsenic is a semi-metallic element found in soils, groundwater, surface water, air, and some foods. Arsenic occurs naturally in the earth’s crust, with higher concentrations in some geographic areas, and in some types of rocks and minerals. In its pure form, arsenic is a gray-colored, odorless, and tasteless metal; arsenic is usually found combined with other elements. When combined with elements other than carbon, arsenic is then called “inorganic arsenic.”
