Molecular speciation of silver nanoparticle for elucidating bioavailability to plants and macrofauna

Silver nanoparticles (AgNP) have been incorporated into various products such as sock and cloth. AgNP in the products can be washed out via laundry and bathing activities and accumulates eventually in sewage sludge. Environmental behaviors of silver and AgNP remain largely unknown, and investigation of silver compounds in soils is key to elucidating environmental fate and toxicity of silver. Our study found that i) solubility of silver compounds and AgNP are dependent on soil's redox potential, ii) Andic soils can retain silver more than lowland gley soils, and iii) AgNP remains persistent in oxic soil conditions.
