Aging of pollution aerosols: an analytical microscopy study

PhD student: Sarah GUIBAUD

The impact of atmospheric aerosols on climate, biogeochemical cycles and human health (via inhalation and/or ingestion) was largely demonstrated. The potential toxicity of atmospheric particles can particularly increase in the presence of trace metals. In this context, this study will focus on atmospheric particles emitted by metallurgy plants. These particles are released in the low troposphere by high-temperature processes and their physical and chemical characteristics can rapidly change. Based on an adequate sampling strategy (airborne sampling and LIDAR sensing), the main goal will be to study fast evolutions of the physicochemical properties of airborne particles in the industrial plume, using complementary analytical techniques to characterize them, such as Cryo-STEM-EDX and related spectroscopies.
