Health Effects of Arsenic Arsenic University of Maine

Health Effects of Arsenic. It was stated in an earlier section (What is arsenic?) that the different forms of arsenic have different toxicities. This is probably due to a number of different factors: how well they get in to the body (absorption), where they are distributed, how they are modified in the body, and how fast they are flushed out.

Mining and Arsenic. Arsenic occurs in various mineral forms, as arsenides in sulphide minerals and as arsenates. The most common mineral is arsenopyrite (FeAsS), which is also found in arsenolite (As 2 O 3), olivenite (Cu 2 OHAsO 4), mimetite (Pb 5 Cl(AsO 4) 3 and cobaltite (CoAsS).. In the weathering of sulphides, arsenic can be oxidised to arsenite and arsenate.
