Quantification of volatile arsenicals in eluates of chemo-traps from transgenic rice with 12-d exposure to 10 μM As(III). Data are means ± SE (n = 2 for blank, n = 4 for WT, n = 10 for arsM). Means followed by the same letter are not significantly different at P < 0.05 using One-Way ANOVA in SPSS. Open bars, blank (chemo-trap control with no rice); hatched bars, WT (wild type, the nontransgenic control); cross-hatched bars, arsM (transgenic rice); SE, standard error.
