报告摘要：
The discharge of plastic waste into the environment has led to an increase in the presence of small plastic particles known as microplastics or nanoplastics. These particles behave differently than larger plastics, raising concerns about their potential impacts on ecosystems, ecological consequences, human health, and the overall well-being of the planet. Inductively coupled plasma mass spectrometry (ICP-MS) in the single-particle mode (SP-ICP-MS), which offers exceptional detection capabilities, has been investigated as a potential candidate for analyzing micro- and nanoplastics. Different strategies, including monitoring natural plastic particles (such as the C13 carbon isotope and fluorine present in PTFE) and the use of metal tags, have been proposed. LC-MS and GC-MS were used to evaluate microplastics as carriers of environmental pollutants. Deconvolution of accurate GC–MS scan data allowed the identification of >130 organic pollutants. Untargeted LC-MS demonstrated the persistence of several pesticides and pharmaceuticals. On the other hand, SP-ICP-MS using the 13C isotope was developed for the detection and measurement of particle size distribution. The developed method was applied to screen microplastics in personal care products and those released from food packaging.
The complementary features of different analytical methods for a comprehensive characterization of the risks posed by micro- and nanoplastics will be highlighted.
报告人简介：
Joanna Szpunar graduated from the Warsaw University of Technology in 1986 and obtained, subsequently, her Ph.D (1992) and D.Sc. (habilitation) (2000) from at the University of Warsaw (Poland). She was post-doctoral fellow (1992-1994) at the University of Antwerp (Belgium) and, in 1995-1996, at the University of Bordeaux (France). Since 1997 she has been working as research engineer at the French National Research Center (CNRS).
In 2007 Joanna Szpunar was awarded the title of professor of chemistry (Poland) and admitted fellow of the Royal Society of Chemistry (UK). Her field of expertise is bio-inorganic speciation analysis with a focus on the identification and quantification of trace element species in biological systems and in the chemistry of metal-biomolecule interactions. She is the author or co-author of one book and more than 200 scientific publications in peer-reviewed international journals. She is member Advisory Boards of JAAS, Metallomics and Separations journals. She is the laureate of the 2013 Analytical Chemistry Committee of the Polish Academy of Science Fijalkowski Award and of the 2017 European Award for Plasma Spectrochemistry.
