Male Syrian golden hamsters were given arsenic trioxide, calcium arsenate, or arsenic trisulfide by intratracheal instillation once a week for 15 weeks. The total doses amounted to mg arsenic. The animals were maintained for lifespan observation. During the study period, 77 percent of the hamsters given arsenic trisulfide died.

The major arsenic minerals occurring in nature are summarized in the work of Smedley and Kinniburgh, which includes, for example, FeAsS, As 2 S 3, and As 4 S 4. These minerals have been identified as an important source and cause of arsenic contaminations in groundwater aquifers [Harvey et al., 2002; Fendorf et al., 2010].

Arsenic in Rocks Arsenic is a naturally occurring element found in many of the rocks and minerals that make up the earth's crust. The minerals with the highest arsenic content are realgar and orpiment, both arsenic sulfides, which contain 70% and 60% arsenic by weight, respectively. These minerals are rare.

Arsenic derived from natural sources occurs in groundwater in many countries, affecting the health of millions of people. The combined effects of As(V) reduction and diagenesis of iron oxide minerals on arsenic mobility are investigated in this study by comparing As(V) and As(III) sorption onto amorphous iron oxide (HFO), goethite, and magnetite at varying solution compositions.
