Environnemental impact of materials and infrastructures

The engineering of construction materials for roads and the subsequent use of road infrastructures are responsible for metallic pollutant dispersion (Zn, Cu, Ni, platinoids...) in the surrounding of environmental soils. The evaluation of their environmental impact environnemental requires the knowledge of the distribution and mobility of these elements. In this context, local analyses techniques such as transmission electron microscopy techniques (images, chemical analyses) are used to first detect these elements present in very low concentration, and then to determine their distribution, their speciation and the nature of the bearing phases.
