Safety & protection
Exposure Control and Personal Protection
Biological Exposure Indices (BEI) [ACGIH] - Inorganic arsenic plus methylated metabolites in urine = 35 ug As/L; end of workweek; Fluorides in urine = 2 mg/L prior to shift or 3 mg/L at end of shift; (Repeated measurements recommended.)
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Arsenic is absorbed mainly by inhalation or ingestion, as to a lesser extent, dermal exposure. It is then distributed throughout the body, where it is reduced into arsenite if necessary, then methylated into monomethylarsenic (MMA) and dimethylarsenic acid (DMA) by arsenite methyltransferase. Arsenic and its metabolites are primarily excreted in the urine. Arsenic is known to induce the metal-binding protein metallothionein, which decreases the toxic effects of arsenic and other metals by binding them and making them biologically inactive, as well as acting as an antioxidant.
