Is the Arrhenius-correction of biodegradation rates, as recommended through REACH guidance, fit for environmentally relevant conditions? An example from petroleum biodegradation in environmental systems
Biodegradation is a major determinant of chemical persistence in the environment and an important consideration for PBT and environmental risk assessments. It is influenced by several environmental factors including temperature and microbial community structure....
Three-way catalyst performance using natural gas with two different sulphur levels
Report no. 6/20: Stoichiometric engines running on natural gas rely on three-way catalysts to meet limits e.g. Euro 6 regarding emissions of hydrocarbons (including methane), carbon monoxide and oxides of nitrogen. As is well known from decades of industry experience...
Real Driving Emissions from Four Euro 6 Diesel Passenger Cars
Report no. 5/20: In Europe, the development and implementation of new regulatory test procedures including the chassis dynamometer (CD) based World Harmonised Light Duty Test Procedure (WLTP) and the road-based Real Driving Emissions (RDE) procedure, has been driven...
