Metals Speciation - Arsenic

Arsenic Speci­a­tion by HPLC-ICP-MS
Arse­nate {As(V)}, Arsenite {As(III)} Inor­ganic Arsenic
FDA 4.11

There are two different forms of arsenic: organic and inor­ganic- and Columbia Labs tests for both. Inor­ganic arsenic is highly toxic and is there­fore a public health concern; the organic form (commonly found in fish and seafood) is less harmful.

The main source of expo­sure to inor­ganic arsenic is food; partic­u­larly grain-based processed prod­ucts such as wheat bread, rice, milk, dairy prod­ucts, and drinking water.

Columbia’s Nutri­tional Testing team recom­mends measuring total arsenic first, then if the level exceeds or pushes the limit, follow up with the speci­a­tion analysis to deter­mine if the inor­ganic arsenic is above or below their internal quality limits.

No limits are set in EU for food in general, but, a maximum level for arsenic in rice has been set by the UN food stan­dards body, the Codex Alimen­ta­rius Commis­sion, at 0.2 mg per kg.

The FDA has estab­lished an action level for inor­ganic arsenic in infant rice cereals of 100 μg/​kg or 100 ppb. This limit is gener­ally applied to food prod­ucts as a recom­mended action limit for inor­ganic arsenic.
