This is the first study on subcellular and chemical forms partitioning of AgNPs in planta under different exposure pathway. Lettuce has higher tolerance to AgNP following foliar exposure than via root exposure. AgNP sequestration in metal-rich granules and heat stable fractions could best explain the AgNP tolerance. Low Ag proportion in inorganic form was potentially associated with AgNPs tolerance. Silver-containing NPs of 23.7 e39.4 nm were detected in planta by spICP-MS analysis.
