Detection and characterization of ZnO nanoparticles in surface and waste waters using single particle ICPMS
Hadioui, Madjid; Merdzan, Vladimir; Wilkinson, Kevin James (American Chemical Society, 2015-04-29)The increasing production of ZnO nanoparticles (nZnO) makes their analysis and characterization extremely important from an ecological risk perspective, especially at the low concentrations at which they are expected to be found in natural waters. ... -
Quantification and characterization of Ti-, Ce- and Ag5 nanoparticles in global surface waters and precipitation
Azimzada, Agil; Jreije, Ibrahim; Hadioui, Madjid; Shaw, Phil; Farner, Jeffrey M.; Wilkinson, Kevin James (American Chemical Society, 2021-06-28)Nanoparticle (NP) emissions to the environment are increasing as a result of anthropogenic activities, prompting concerns for ecosystems and human health. In order to evaluate the risk of NPs, it is necessary to know their concentrations in various ... -
Quantification of ZnO nanoparticles and other Zn containing colloids in natural waters using a high sensitivity single particle ICP-MS
Fréchette-Viens, Laurie; Hadioui, Madjid; Wilkinson, Kevin James (Elsevier, 2019-03-08)Inductively coupled plasma mass spectrometry in single particle mode (SP-ICP-MS) is becoming a powerful tool of choice for the quantification and characterization of metallic nanoparticles (NP) at very low concentrations. Nonetheless, this technique ... -
Release of TiO2 nanoparticles from painted surfaces in cold climates : characterization using a high sensitivity single-particle ICP-MS
Azimzada, Agil; Farner, Jeffrey M.; Hadioui, Madjid; Liu-Kang, Carolyn; Jreije, Ibrahim; Tufenkji, Nathalie; Wilkinson, Kevin James (Royal Society of Chemistry, 2020)Paints and coatings represent one of the major applications of TiO2 nanoparticles (NPs). While it has been previously shown that NPs are released from painted surfaces, there is still a lack of experimental data on their release rates under natural ... -
Sample preparation for the analysis of nanoparticles in natural waters by single particle ICP-MS
Jreije, Ibrahim; Hadioui, Madjid; Wilkinson, Kevin James (Elsevier, 2021-11-12)With the significant increase in the production and use of nanoparticles (NP), concern is increasing over their release into their environment. Single particle inductively coupled plasma mass spectrometry (SP-ICP-MS) is emerging as one of the best ... -
Separation, detection and characterization of nanomaterials in municipal wastewaters using hydrodynamic chromatography coupled to ICPMS and single particle ICPMS
Proulx, Kim; Hadioui, Madjid; Wilkinson, Kevin James (Springer, 2016-03-12)Engineered nanoparticles (ENP) are increasingly being incorporated into consumer products and reaching the environment at a growing rate. Unfortunately, few analytical techniques are available that allow the detection of ENP in complex environmental ...
