Mixtures of rare earth elements show antagonistic interactions in Chlamydomonas reinhardtii
(Elsevier, 2021-06-14)In order to better understand the environmental risks of the rare earth elements (REEs), it is necessary to determine their fate and biological effects under environmentally relevant conditions (e.g. at low concentrations, REE mixtures). Here, the ... -
Thermal degradation of conventional and nanoencapsulated azoxystrobin due to processing in water, spiked strawberry and incurred strawberry models
(American Chemical Society, 2022-09-21)Nanoencapsulated formulations of pesticides have been recently developed, and some products are now marketed for specific applications in agriculture. Pesticide residues present in raw agricultural products can degrade or react during food processing ... -
Field evaluation of the potential effects of polymer and silica-based nanopesticides on strawberries and agricultural soils
(Royal Society of Chemistry, 2022-08-18)Polymeric and SiO2 nanoparticles can be used as nanocarriers to improve the efficacy of pesticide delivery in agriculture. However, the environmental fate and potential risks of this type of nanopesticides in agroecosystems remain poorly understood. ... -
Development of an LC-MS-based method to study the fate of nanoencapsulated pesticides in soils and strawberry plant
(Elsevier, 2021-12-04)The increased production and use of nanopesticides will increase the likelihood of their exposure to humans and the environment. In order to properly evaluate their risk, it will be necessary to rigorously quantify their concentrations in major ... -
Detection and characterization of ZnO nanoparticles in surface and waste waters using single particle ICPMS
(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. ... -
Separation, detection and characterization of nanomaterials in municipal wastewaters using hydrodynamic chromatography coupled to ICPMS and single particle ICPMS
(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 ... -
Quantification of ZnO nanoparticles and other Zn containing colloids in natural waters using a high sensitivity single particle ICP-MS
(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 ... -
Linking the chemical speciation of cerium to its bioavailability in water for a freshwater alga
(Wiley, 2015-03-13)Over the past decade, researchers have begun to use metals of the lanthanide family for numerous applications, including liquid crystal display (LCD) screens, optical fibers, and laser technology. Unfortunately, little is presently known about their ... -
Sample preparation for the analysis of nanoparticles in natural waters by single particle ICP-MS
(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 ... -
Release of TiO2 nanoparticles from painted surfaces in cold climates : characterization using a high sensitivity single-particle ICP-MS
(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 ...
