TLDR
It is suggested that Ag MNP coating does not need to be taken into account to understand fate of AgMNPs applied to soil through biosolids amendment, because pre-incubation with sewage sludge negated these effects.About:

Nanotoxicity of engineered nanomaterials (ENMs) to environmentally relevant beneficial soil bacteria - a critical review.
TL;DR: This review explores what is known regarding ENM toxicity to important soil bacteria, with a focus on ENMs which are expected to accumulate in terrestrial ecosystems at the highest concentrations and pose the greatest potential threat to soil micro-organisms having potential indirect detrimental effects on plant growth.

Silver nanoparticles in soil: Aqueous extraction combined with single-particle ICP-MS for detection and characterization
Karrar N.M. Mahdi,Karrar N.M. Mahdi,Ruud J. B. Peters,Erwin Klumpp,Steffi Bohme,Martine van der Ploeg,Coen J. Ritsema,Violette Geissen +7 more
TL;DR: In this article, the authors describe the development and validation of a method for the extraction, quantification and particle size determination of AgNPs in soils, which consists of pre-wetting the sample followed by an aqueous extraction, using sonication to re-suspend adsorbed AgNs, and analysis of the extract with single particle ICP-MS.

Silver nanoparticles in aquatic sediments: Occurrence, chemical transformations, toxicity, and analytical methods.
Jian Zhao,Xinjie Wang,Son A. Hoang,Nanthi Bolan,M. B. Kirkham,Jingnan Liu,Xinghui Xia,Yang Li +7 more
TL;DR: This review focuses on various chemical transformations of AgNPs in sediments, which have not been well outlined before and are needed to investigate diverse chemical transformations in various sediments through development of novel techniques and mathematical models.
Journal ArticleDOI
Role of rain intensity and soil colloids in the retention of surfactant-stabilized silver nanoparticles in soil.
TL;DR: Heavy rain treatment and natural rainfall revealed enhanced AgNP transport within the Ap horizon, which was attributed to the high pore water flow velocities and to the mobilization of AgNP-soil colloid associations.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.
Journal ArticleDOI
Analysis of Macromolecular Polydispersity in Intensity Correlation Spectroscopy: The Method of Cumulants
TL;DR: The first order electric field correlation function of laser light scattered by polydisperse solutions of macromolecules can be written as a sum or distribution of exponentials, with decay rates proportional to the diffusion coefficients of the solute molecules as discussed by the authors.

Modeled Environmental Concentrations of Engineered Nanomaterials (TiO2, ZnO, Ag, CNT, Fullerenes) for Different Regions
TL;DR: The results of this study indicate that risks to aquatic organisms may currently emanate from nano- Ag, nano-TiO(2), and nano-ZnO in sewage treatment effluents for all considered regions and for nano-Ag in surface waters.

Nanoparticle Silver Released into Water from Commercially Available Sock Fabrics
Troy M. Benn,Paul Westerhoff +1 more
TL;DR: Variable leaching rates among sock types suggests that the sock manufacturing process may control the release of silver, and physical separation and ion selective electrode (ISE) analyses suggest that both colloidal and ionic silver leach from the socks.
