Arsenate is a chemical compound that contains arsenic in its +5 oxidation state, typically represented as AsO4^3-. It is commonly found in nature as a mineral and can also be produced through various industrial processes. Arsenate is often associated with environmental concerns, particularly in relation to soil and water contamination. In agriculture, arsenate compounds have been used as herbicides and pesticides, but their use has declined due to toxicity and potential health risks. Exposure to arsenate can lead to serious health issues, including skin lesions and increased risk of cancer, making it a significant public health concern.
