Speciation of Arsenic in Apple Juice by LC-ICP-MS

摘要

The different physico-chemical forms of most elements vary in terms of mobility, toxicity and bioavailability. For example, arsenic species such as the inorganic trivalent arsenic (As III) and pentavalent arsenic (AsV) are highly toxic whereas the organic forms as monomethyl arsenic (MMA) and dimethyl arsenic (DMA) have significantly reduced toxicities. Reporting only the total concentrations can often be misleading.
