Pyrrolizidine alkaloids (PAs) are produced by various plant species and have been detected as contaminants in food and feed. Monitoring programmes should include PAs that are present in relevant matrices and that exhibit a high toxic potential. The aim of the present study was to use a bioassay-directed analysis approach to identify relevant PAs not yet included in monitoring programmes. To that end, extracts of Heliotropium e...

The impact of electric vehicles on the electricity grid has been focused on by the literature in many facets, comprising considerations of the electricity system of a single household up to the highest voltage grid level. But each of these analyses is focusing on a single grid level. While the impact on the local level depends strongly on the specific environment and is consequently diverse, there is strong evidence that the i...

The electrification of the transport sector plays a key role in the global energy transition and it is of great necessity to assess emissions induced by electric vehicles in the long term for effective policy‐making. Typical life cycle assessment may not consider the impact of electric vehicle integration in future electricity systems adequately, or the time‐dependent characteristics of electricity generation mix and EV chargi...

Summary Plug‐in hybrid electric vehicles (PHEVs) combine electric and conventional propulsion. Official fuel consumption values of PHEVs are based on standardized driving cycles, which show a growing discrepancy with real‐world fuel consumption. However, no comprehensive empirical results on PHEV fuel consumption are available, and the discrepancy between driving cycle and empirical fuel consumption has been conjectured to be...
