Y1 - 2018 N1 - T2 - Poisoning & Drug Overdose, 7e AB - Arsenic compounds are found in a select group of industrial, commercial, and pharmaceutical products. Use of arsenic as a wood preservative in industrial applications (eg, marine timbers and utility poles) accounts for two-thirds of domestic consumption, but former widespread use in new lumber sold for residential purposes (eg, decks, fencing, play structures) ended with a voluntary ban effective at the end of 2003. Arsenic-treated lumber used in residential structures and objects created before 2004 has not been officially recalled or removed. Virtually all arsenic in pesticides and herbicides in the United States have been withdrawn or subject to phaseout with the exception of the limited use of monosodium methane arsonate (MSMA) as an herbicide. Until recently phenylarsenic compounds were used as feed additives for poultry and swine, and poultry litter used as a soil amendment sometimes contained low levels of soluble arsenic. Intravenous arsenic trioxide, reintroduced to the US Pharmacopoeia in 2000, is used as a drug for cancer chemotherapy. Inorganic arsenic is used in the production of nonferrous alloys, semiconductors, and certain types of glass. Inorganic arsenic is sometimes found in folk remedies and tonics, particularly from Asian sources. Artesian well water can be contaminated by inorganic arsenic from natural geologic deposits, and elevated levels of arsenic may be encountered in mine tailings and sediments and coal fly ash. Arsine, a hydride gas of arsenic, is discussed on Arsine. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/19 UR - accessmedicine.mhmedical.com/content.aspx?aid=1174605159 ER -
