From: Nanoremediation of As and metals polluted soils by means of graphene oxide nanoparticles
Influence on available phosphorus concentration by means of nZVI and nGO in the As-Metals polluted soil - AM- (A) and the As-polluted soil -A- (B). For each column, different letters in different samples indicate significant differences (n = 3, ANOVA; P < 0.05). Error bars represent standard deviation.
