Different collector types, sample workup procedures and analysis methods to measure the deposition of polycyclic aromatic hydrocarbons (PAH) were tested and compared. Whilst sample workup and analysis methods did not influence the results of PAH deposition measurements, using different collector types changed the measured deposition rates of PAH significantly. The results obtained with a funnel-bottle collector showed the highest deposition rates and a low measurement uncertainty. The deposition rates obtained with the wet-only collectors were the lowest at industrial sites and under dry weather conditions. For the open-jar collectors the measurement uncertainty was high. Only at an industrial site with extremely high PAH deposition rates the results of open-jar collectors were comparable to those obtained with funnel-bottle collectors. Thus, if bulk deposition of PAH has to be measured, funnel-bottle combinations are proved to be the collectors of choice. These collectors were the only ones always fulfilling the requirements of European legislation. This journal is © 2012 The Royal Society of Chemistry.

A long-term field experiment conducted in a Norway spruce forest at Solling, Central Germany, was used to verify and compare the response of lignin-decomposing fungal communities in soils receiving current and preindustrial atmospheric nitrogen (N) input for 14.5 years. Therefore, we investigated the decomposition of lignin compounds in relation to phenol oxidase activity and the diversity of basidiomycetes containing laccase genes in organic and mineral horizons. Lignin-derived CuO oxidation products and enzyme activity decreased with soil depth, while the degree of oxidative transformation of lignin increased. These patterns did not change with reduced atmospheric N input, likely reflecting a lasting saturation in available N. The laccase gene diversity decreased with soil depth in spring. In autumn, this pattern was only found in the control plot, receiving current N input. Principal component analysis confirmed the depth profile and distinguished a response of the fungal community to reduced N deposition for most organic layers in spring and a roof effect for the Oe layer in autumn. These responses of the fungal community did not translate into changes in enzyme activity and lignin content and decomposition, suggesting that transformation processes in soils are well buffered despite the rapid response of the microbial community to environmental factors. © 2010 Federation of European Microbiological Societies.

Case studies of two Natura 2000 Sites in Saxony-Anhalt Climate change represents an additional hazard for many protected species. In the light of the supposed increase in aridity this especially applies to aquatic ecosystems and wetlands. The study presented aimed to analyse the impact of climate change on European protected species based on two Natura 2000 sites in Saxony-Anhalt. In the first step the study assessed the degree and type of climate sensitivity for each species using literature research. On this base the bio-climatic response of the species could be predicted for three periods (2011-2040, 2041-2070, 2071-2100). The comparison between projected climate parameters of the areas analysed and the species-specific climatic envelope allowed to determine whether or not a species might be able to persist in the examined areas regarding each of the three time periods. The results show that in future many of the considered species could suffer from a lack of cold. To minimise the expected impacts of climate change area-specific management strategies are outlined.

In co-operation with the Municipality of Halle (Saale) the Environmental Protection Agency of Saxony-Anhalt carried out an experimental investigation of the practical use of calcium magnesium acetate (CMA), so-called "fine dust-binder". The aim of the study was to investigate the dust-binding effect of CMA under real field conditions. As a result of the test a dust-binding impact of CMA could be proved. In the investigation period of two months an averaged mitigation of fine dust concentration of about 0,7 μg/m3 was found. The detailed analysis of the time series revealed that the increase of particle pollution at a traffic site compared with a reference site could be limited in some situations by using CMA. Due to the given practical field conditions the CMA use in Halle (Saale) only resulted in a small contribution to the mitigation of the fine dust pollution.
