From: The potential benefits and limitations of different test procedures to determine the effects of Ag nanomaterials and AgNO3 on microbial nitrogen transformation in soil

Figure 2

Effect of silver nanomaterials and AgNO 3 on nitrate concentration with (NH4) 2 SO 4 as nitrogen source [[2]]. The results for AgNO3 were corrected by the nominal nitrate concentration added with the test substance. Left figure column: mean activity and standard deviation. Right figure column: percentual deviation. Asterisks indicate a statistically significant difference to controls (p ≤ 0.05).
