The environment is contaminated with numerous pollutants, such as heavy metals, microplastics (MPs), perfluorinated organic compounds, and pesticides, which toxicity and harmful impacts on human health, also related with gestational life, presents a critical emerging area for research. To start investigating this, we propose model MPs, labeled with cadmium-selenide quantum dots to provide new data on cell-MPs accumulation and toxicity in a human placenta cell line (BeWo cells) taking advantages of synchrotron radiation X-ray elemental imaging, combine to light fluorescence microscopy. We apply for 12 shifts at ID21 and 9 shifts at ID16A.
