Journal ArticleDOI
Extracting Metallic Nanoparticles from Soils for Quantitative Analysis: Method Development Using Engineered Silver Nanoparticles and SP-ICP-MS
Dina Schwertfeger,Jessica Velicogna,Alexander H. Jesmer,Selin Saatcioglu,Heather McShane,Richard P. Scroggins,Juliska Princz +6 more
TL;DR: The nanoparticulate Ag extracted by this method represents the upper limit of the potentially dispersible nanopartsiculate fraction, thus providing a benchmark with which to make quantitative comparisons, while presenting a suspension suitable for a myriad of other characterization analyses.
Journal ArticleDOI
Single Particle-Inductively Coupled Plasma Mass Spectroscopy Analysis of Metallic Nanoparticles in Environmental Samples with Large Dissolved Analyte Fractions.
Dina Schwertfeger,Jessica R. Velicogna,Alexander H. Jesmer,Richard P. Scroggins,Juliska Princz +4 more
TL;DR: The technique proposed here is meant to offer a systematic and reproducible approach to the SP-ICPMS analysis of environmental samples and improve the quality and consistency of data generated from this relatively new analytical tool.
Journal ArticleDOI
The bioaccumulation of silver in Eisenia andrei exposed to silver nanoparticles and silver nitrate in soil
Jessica R. Velicogna,Dina Schwertfeger,Alexander H. Jesmer,Richard P. Scroggins,Juliska Princz +4 more
TL;DR: In this article, the bioaccumulation potential of silver from exposure to AgNO 3 and Ag nanoparticles (AgNP) was investigated, and the results demonstrated very low bioaccUMulation potential for all exposure scenarios, producing bioaccu-cation factors (BAF k ) of 0.89 and 0.74 for with AgNP A (20nm) and Ag + (as Ag NO 3 ), respectively, in soil, and0.12 AgNP B in biosolids-amended soil.
Journal ArticleDOI
Soil invertebrate toxicity and bioaccumulation of nano copper oxide and copper sulphate in soils, with and without biosolids amendment.
Jessica R. Velicogna,Dina Schwertfeger,Alexander H. Jesmer,Claudia Beer,Joner Kuo,Maria C. DeRosa,Rick Scroggins,Myron L. Smith,Juliska Princz +8 more
TL;DR: The fate, toxicity and bioaccumulation of copper oxide nanoparticles (nCuO) was investigated in soil, with and without biosolids amendment, through chronic exposures using the earthworm, Eisenia andrei, and the collembolan, Folsomia candida as mentioned in this paper.
Journal ArticleDOI
Fate and removal of silver nanoparticles during sludge conditioning and their impact on soil health after simulated land application.
Zainab Abdulsada,Zainab Abdulsada,Richard Kibbee,Dina Schwertfeger,Juliska Princz,Maria C. DeRosa,Banu Örmeci +6 more
TL;DR: In this paper, the fate and removal of AgNPs during chemical conditioning of anaerobically digested sludge and their impact on soil bacteria and health after land application were investigated.
