Arsenic ranks twentieth among the elements in abundance in the earth's crust. The abundance of arsenic in the continental crust of the earth is generally given as 1.5–2 ppm. Thus, it is relatively scarce. Nevertheless, it is a major constituent of no fewer than 245 mineral species. Arsenic is found in high concentration in sulfide deposits, where it is …
The arsenic is naturally occurring, but it enters private wells. Of course, people who drink this water, including pregnant and nursing women, are exposed to the arsenic.

This form of arsenic tends to be more toxic and has been linked to cancer. Organic compounds (arsenic combined with carbon and other elements): These compounds tend to be much less toxic than the inorganic arsenic compounds and are not thought to be linked to cancer. Organic arsenic compounds are found in some foods, such as fish and shellfish.
