Distribution of arsenicals in tissues of Ciona intestinalis following exposure to unamended seawater (−) or seawater with 1 ppm of arsenic (as arsenite) (+) for 1 day (day 1) or 5 days (day 5). Results shown for branchial sac (BS), gastrointestinal tract (GI), and heart (HT). Detected species are iAs, MAs, DMAs, and TMAs. Means and SDs shown for summed concentrations of speciated arsenicals in tissues (n = 3–8). *A significant difference (p ≤ 0.008) between treatment groups in the summed concentrations of arsenicals in a tissue on day 1 or day 5. #A significant difference (p = 0.002) in the summed concentrations of arsenicals in the branchial sac between days 1 and 5. †A significant difference (p ≤ 0.003) in the concentration of a speciated arsenical in a tissue between days 1 and 5.
