Short summary
Atmospheric mercury and knowledge of its transformations and processes are of great importance for lowering its anthropogenic emissions. To ensure that, it is crucial to have a tested and validated measurement procedure. Since this is not always the case, we performed experiments that provided insight into commonly used atmospheric mercury sampling methods. The results showed that some sampling methods are unsuitable, and some are useful if we consider the results obtained from this work.
