Universidad de Zaragoza (orcid)0000-0002-8460-6020 Comparative study of extraction methods of silver species from faeces of animals fed with silver-based nanomaterials 2023 Access copy available to the general public Unrestricted Extractions methods based on ultrapure water, tetramethylammonium hydroxide (TMAH), and tetrasodium pyrophosphate (TSPP) were applied to faeces collected from two in vivo experiments of pigs and chickens fed with a silver-based nanomaterial to study the fate and speciation of silver. For TMAH extraction, cysteine and CaCl2 were used to evaluate their stabilization effect on the silver forms. The analytical techniques single-particle inductively coupled plasma mass spectrometry (SP-ICP-MS), hydrodynamic chromatography hyphenated to ICP-MS (HDC-ICP-MS) and asymmetric flow field flow fractionation coupled to ICP-MS (AF4-ICP-MS) were applied to the simultaneous detection of particulate and dissolved silver. Results have shown that water extraction was a suitable option to assess the environmental release of silver, with percentages of 3 and 9% for faeces of pigs and chickens, respectively. The use of TMAH extraction combined with SP-ICP-MS analysis was useful to characterize Ag-containing particles (less than 1%). Both stabilizers, cysteine and CaCl2, have a similar effect on silver nanoparticle preservation for chicken faeces, whereas cysteine-Triton was better for pig samples. In any case, silver extraction efficiency with TMAH was low (39–42%) for both types of faeces due to a matrix effect. TSPP followed by ICP-MS enabled the fractionation of the silver in the faeces, with silver sulphide (41%) and ionic silver (62%) being the most abundant fractions. info:eu-repo/grantAgreement/ES/DGA-FEDER/E29-17R info:eu-repo/grantAgreement/EC/H2020/801586/EU/International Doctoral Programme for Talent Attraction to the Campus of International Excellence of the Ebro Valley/IberusTalent This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 801586-IberusTalent info:eu-repo/grantAgreement/ES/MICINN/PID2021-123203OB-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 5.4 2023 CHEMISTRY, ANALYTICAL 15 / 106 = 0.142 2023 Q1 T1 0.848 2023 Analytical Chemistry 2023 Q1 9.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Bakir, Mariam (orcid)0000-0002-8066-7117 Ben-Jeddou, Khaoula Universidad de Zaragoza (orcid)0000-0002-1532-3916 Bolea, Eduardo Universidad de Zaragoza (orcid)0000-0001-5382-0561 Pérez-Arantegui, Josefina Universidad de Zaragoza (orcid)0000-0002-4681-3934 Laborda, Francisco Universidad de Zaragoza (orcid)0000-0002-4169-0357 2009 750 Universidad de Zaragoza Dpto.
