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 ...
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 ...
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 ...
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 ...
Biological impacts of Ce nanoparticles with different surface coatings as revealed by RNA-Seq in Chlamydomonas reinhardtii
(Elsevier, 2020-05-18)
In order to better understand the risks of engineered nanoparticles (ENPs), it is necessary to determine their fate
and biological effects under realistic exposure scenarios (e.g. low ENP concentrations). RNA-Seq was ...
Quantification and characterization of Ti-, Ce- and Ag5 nanoparticles in global surface waters and precipitation
(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 ...
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 ...
Distinguishing the effects of Ce nanoparticles from their dissolution products : identification of transcriptomic biomarkers that are specific for ionic Ce in Chlamydomonas reinhardtii
(Oxford University Press, 2020-12-11)
Cerium (Ce) is a rare earth element that is incorporated in numerous consumer products, either in its cationic form or as engineered nanoparticles (ENPs). Given the propensity of small oxide particles to dissolve, it is ...
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 ...
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 ...
