The influence of As(V) (50 μg L−1&2 μg L−1) andPO4 3− (3 mg L−1&0.12 mg L−1) exposures on arsenic cycling
by the marine phytoplankton Dunaliella tertiolecta was investigated both separately and in combination.
Total arsenic concentrations in D. tertiolecta tissue ranged from 8 to 10 μg g−1 when exposed to 50 μg L−1 As(V),
and 2–4 μg g−1when exposed to 2 μg L−1 As(V), with PO4 3− exposure having little to no influence on total arsenic
concentrations.
