The scope of this work is to develop a comprehensive understanding of the aerosol pollution in the megacity Beijing. The focus lies on the interaction of anthropogenic and geogenic aerosol particles, their spatio-temporal variation, the most important pollution sources as well as the impact of particulate aerosols on human health and the environment. Furthermore, the bioavailable fraction of metal concentrations and the effect of mitigation measures during the 2008 Olympic Games were evaluated.

This publication presents results of an interdisciplinary field study assessing the contribution of biological and inorganic processes in the mobilisation and accumulation of arsenic in groundwater of the Bengal Delta Plain, West Bengal. Investigations were focussed on the distribution of arsenic in sediments and shallow groundwater of two representative study sites. All results were combined in an effort to develop a conceptional model describing the mobility of arsenic in West Bengal aquifers.

Diese Studie hat ein vollständiges Verfahren für die Messung der Sauerstoff-Isotope in Arsen-Oxianionen in natürlichen Wässern durch den Einsatz verschiedener Adsorbentien entwickelt. Experimente zum kinetischen Austausch von Sauerstoff zwischen AsO43- und Wasser haben gezeigt, dass sich das Gleichgewicht bei verschiedenen pH-Bedingungen und Temperaturen in sehr kurzer Zeit einstellt.
