Arsenicwas evenly distributed (≈33%) between the threemajor biochemical cell fractions (lipid,water, residue)
in cultures exposed to high As(V):high PO4 3− concentrations. Under lowAs(V):high PO4 3− exposures arsenic was
predominantly lipid-soluble (40–55%) and residue bound (30–40%).When exposed to high As(V):lowPO4 3−concentrations
arsenic was predominantly residue bound (50–70%) and lipid-soluble (20–40%), whilst under low
As(V):low PO4 3− exposures arsenic was predominantly residue bound (75–80%).
