Arsenic, a metalloid that exists by nature, reaches the earth either by natural or anthropogenic events and is considered an emerging pollutant. The existence of arsenic in soil systems is a fate to the environment since it is mobile and being transported to other systems because of its bioavailability and speciation process. Arsenic transformation in …
In addition, arsenic has been widely used in insecticides and pesticides due to its germicidal power, but the use of inorganic arsenic compounds in pesticides is no longer permitted in North America. The inorganic arsenic compounds, primarily, sodium arsenite, have been widely used as a weed killer, and non-selective soil sterilant .

earth's crust and often forms compounds by combining with oxygen, chlorine, and sulfur. As water passes through and over soil and rock formations, it dissolves many compounds and minerals including arsenic. The result is that varying amounts of soluble arsenic are present in some water sources. Arsenic chemistry is complex because it has many ...
