From: Partitioning of silver and chemical speciation of free Ag in soils amended with nanoparticles
Measurements of Ag+and total solution Ag (presumed dissolved) following the addition of either nAg and AgNO 3 in Agricultural soil 1. The blue diamonds represent free Ag+ for the AgNO3 treatment, the red squares are for the <0.45 μm fraction in the AgNO3 treatment, the green triangles are for free Ag+ for the nAg treatment and the purple X are for the <0.45 μm fraction in the nAg treatment.
