Elements concentrations prior to the treatment (t0) and after 14 days of exposure to either the As or the As + Si treatment (t14d). Values shown in the form mean ± S.E. (n = 3). Values equal to 0 means BDL. Different superscript letters (a through c) within a column identify means differing significantly from one another (p ≤ 0.05)
