PetroTox version 4.0 User Manual
Report no. 7/20: PetroTox is a modelling tool implementing the Target Lipid Model (TLM) for the calculation of the aquatic toxicity of complex hydrocarbon mixtures. The model allows for the calculation of acute and chronic toxicity values for several trophic levels,...![Is the Arrhenius-correction of biodegradation rates, as recommended through REACH guidance, fit for environmentally relevant conditions?

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](https://www.concawe.eu/wp-content/uploads/20.6-report-1-635x675.png)
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...![Air emissions from the refining sector. Analysis of E-PRTR data 2007-2017](https://www.concawe.eu/wp-content/uploads/Capture-5-614x675.png)
