Laser ablation-based techniques for microplastic analysis
Pavlína Modlitbová, Lukas Brunnbauer, Gabriela Kalčíková, Aida Fazlić, Andreas Limbeck, Pavel Pořízka, Jozef Kaiser
Pregledni znanstveni članek
Oznake: mikroplastika;analizne metode;laserska ablacija;LA-ICP-MS;
Microplastics have emerged as significant environmental contaminants due to the increasing production of polymer-based products and their limited disposal options. The persistence, bioaccumulation potential, and ability of microplastics to adsorb and transport toxic contaminants pose a risk to ecosy ...

People are exposed to microplastics (MPs) on a large scale in everyday life. However, it is not clear whether MPs can also be distributed and retained in certain tissues. Therefore, the development of analytical methods capable of detecting MPs in specific human organs/tissues is of utmost importanc ...

Laser-induced breakdown spectroscopy for direct analysis of pristine and environmentally aged microplastics
Pavlína Modlitbová, Dominik Kočenda, Daniel Holub, Mark Starin, Janja Novak, Ula Rozman, Gabriela Kalčíková, Lukas Brunnbauer, Andreas Limbeck, Pavel Pořízka, Jozef Kaiser

Oznake: mikroplastika;biotsko staranje;abiotsko staranje;lasersko inducirana prebojna spektroskopija;microplastics;biotic aging;abiotic aging;laser-induced breakdown spectroscopy;
This study investigates the potential of Laser-Induced Breakdown Spectroscopy (LIBS) combined with Principal Component Analysis (PCA) for the differentiation and characterization of microplastics (MPs) in various stages of environmental aging. Three commonly encountered polymer types, polystyrene, p ...

Laser-based techniques
Pavel Pořízka, Lukas Brunnbauer, Michaela Porkert, Ula Rozman, Gregor Marolt, Daniel Holub, Martin Kizovský, Markéta Benešová, Ota Samek, Andreas Limbeck, Jozef Kaiser, Gabriela Kalčíková

Microplastics found in the environment are often covered with a biofilm, which makes their analysis difficult. Therefore, the biofilm is usually removed before analysis, which may affect the microplastic particles or lead to their loss during the procedure. In this work, we used laser-based analytic ...

Investigating aquatic biodegradation and changes in the properties of pristine and UV-irradiated microplastics from conventional and biodegradable agricultural plastics
Ula Rozman, Aida Fazlić, Lukas Brunnbauer, Janja Novak, Anita Jemec, Jernej Imperl, Jiří Kučerík, Petra Procházková, Stefania Federici, Rachel Hurley, Andrijana Sever Škapin, Pavlína Modlitbová, Pavel Pořízka, Jozef Kaiser, Andreas Limbeck, Gabriela Kalčíková

There is an increasing tendency to replace conventional agricultural plastic mulching films with biodegradable alternatives. However, while the latter biodegrade well under controlled conditions (e.g. industrial compost), their biodegradation in non-target environments (e.g. aquatic environments) is ...
