#ExistInterpDataSet>
| Interpretive Data: |
#ExistInterpData>For specimens with a total arsenic concentration between 35-2000 ug/L, the proportion of organic, inorganic, and methylated forms is determined. The organic forms of arsenic, most commonly arsenobetaine, are considered nontoxic and arise primarily from food. Inorganic forms of arsenic [As(III) and As(V)] are most toxic. Methylated forms (MMA and DMA) arise primarily from metabolism of inorganic forms but may also come from dietary sources and are of moderate toxic potential. Specific toxic thresholds for arsenic are not well defined but the Biological Exposure Index established by ACGIH for the sum of the inorganic and methylated forms of arsenic is 35 ug/L. As this test does not detect all species of arsenic, it is expected that the sum of the organic, inorganic and methylated forms will not equal the total arsenic concentration.
