Development and evaluation of a pretreatment procedure for single particle ICP-MS quantitative analysis of microplastics in inorganic-carbon-rich water samples
Pia Leban, Aljaž Iveković, Janja Vidmar
Izvirni znanstveni članek
Oznake: nanoplastika;voda;pipe;microplastics;tap water;
This study evaluates the applicability of single particle inductively coupled plasma mass spectrometry (spICP-MS) for the quantitative detection of small microplastics (MPs) through monitoring of the carbon signal in tap water. To overcome high background signal originating from dissolved inorganic ...

Oznake: ekstrakcija mikroplastike;pridobivanje olja;ločevanje gostote;GC–MS;masna spektrometrija;plastični polimeri;polietilen tereftalat;polietilen;microplastic extraction;oil extraction;density separation;mass spectrometry;plastic polymers;polyethylene terephthalate;polyethylene;
Microplastic pollution is globally widespread; however, the presence of microplastics in soil systems is poorly understood, due to the complexity of soils and a lack of standardised extraction methods. Two commonly used extraction methods were optimised and compared for the extraction of low-density ...

Oznake: magistrska dela;sanitarno inženirstvo;oljna ekstrakcija;ločevanje na osnovi gostote;plinska kromatografija z masno spektrometrijo;mikroplastika;aluvialna prst;kompost;
Uvod: Plastika kot vseprisoten material je v okolju izpostavljena vremenskim vplivom, kjer se drobi v manjše delce (< 5 mm), ki jim pravimo mikroplastika. Kmetijska dejavnost (uporaba plastičnih folij, uporaba komposta in odpadnega blata kot gnojila) predstavlja glavni vir vnosa mikroplastike v okol ...

Critical evaluation of enzymatic extraction for quantification of europium-doped polystyrene nanoplastics in tomato tissues by single particle ICP-MS
Harshit Sahai, Pia Leban, Ester Heath, Nina Kacjan-Maršić, Špela Železnikar, Matejka Podlogar, Tina Radošević, María Jesús Martinez Bueno, Janja Vidmar
Izvirni znanstveni članek
Oznake: nanoplastika;evropij;nanoplastics;europium;
This study critically evaluates an analytical approach combining enzymatic extraction and single particle ICP-MS (spICP-MS) for quantifying europium-doped polystyrene nanoplastics (Eu-PS-NPs) bioaccumulated in tomato tissues. Optimization of extraction parameters identified citrate buffer at pH 6.5 ...

This study evaluated the impact of 200 nm polystyrene (PS) nanoplastics (NPs) on the uptake and distribution of potentially toxic elements (PTEs), including chromium (Cr), cadmium (Cd), lead (Pb), and zinc (Zn), in hydroponically grown tomato plants. To distinguish naturally occurring PTEs from thos ...
