Effects of sulfidation of silver nanoparticles on the Ag uptake kinetics in Brassica rapa plants

Metal transfer to sediments, invertebrates and fish following waterborne exposure to silver nitrate or silver sulfide nanoparticles in an indoor stream mesocosm

“…In our previous work, Ag 2 S NPs, as the most relevant environmental transformation (form) of Ag NPs, was explored for its bioaccumulation potential in single species studies on: dicotyledonous crop, Khodaparast et al (2022); wheat crop, Lahive et al (2021); earthworms, Baccaro et al (2019); meal worms, Khodaparast et al (2021); planarians, Silva et al (2022); aquatic snails, Silva et al (2020) and trout, Clark et al (2019a).…”

Recent Advances and Perspectives of Nanomaterials in Agricultural Management and Associated Environmental Risk: A Review

“…Recently, another study concluded that different forms of silver nanoparticles (20 nm Ag 2 S NPs, 3–8 nm Ag NPs, 50 nm Ag NPs and AgNO 3 ) had differing uptake and bioaccumulation in the life cycle of Brassica rapa . They showed that pristine Ag NPs accumulated 14 times more Ag than other sulfide silver forms [ 205 ]. Therefore, a major factor determining the difference in uptake and NP accumulation is the stability of the NPs.…”

Application of nano-agricultural technology for biotic stress management: mechanisms, optimization, and future perspectives

“…34 For instance, after 5 days exposure with Ag 0 NMs, the content of AgCl, Ag 2 S, and Ag-thiolate complexes counted for 71.3% of total Ag in rice roots. 35 These transformations of Ag 0 NMs decrease their antimicrobial/insecticidal ability and translocation in plants, 36,37 and in turn decrease their efficiency as controls of crop diseases and pests. Although several studies reported that the applied Ag 0 NMs had no effect on the growth of non-target organisms, Ag 0 NMs could transfer from crop to non-target organisms (e.g., snails) and have exhibited biomagnification (trophic magnification factor: 1.21) in natural food chains.…”
