Method optimization for chemical analysis of ultrafine particles (UFP)
Knowledge of the sources of ultrafine particles (UFP), their distribution in the ground-level atmosphere, and their chemical composition are key factors needed to assess whether they pose a risk to human health. However, risk assessment is currently limited by the quality and comparability of methods used to characterize UFP in the environment. Therefore, the goal of this project is to optimize methods for the separation, collection, and analysis of UFP such that a reference for standardized measurements of UFP is established and an evaluated, flexibly deployable mobile module enables comparable measurements at different sites. Both approaches were carried out with high-quality analysis of the chemical composition of ultrafine particles. The measurements on temporal and spatial variability allow the identification of specific source and exposure situations and allow conclusions on possible risk factors for human health.
