Modeling the GCxGC elution patterns of a hydrocarbon structure library to innovate environmental risk assessments of petroleum substances

Modeling the GCxGC elution patterns of a hydrocarbon structure library to innovate environmental risk assessments of petroleum substances

Dec 7, 2022

Comprehensive two-dimensional gas chromatography (GCxGC) offers unrivaled separation of petroleum substances, which can contain thousands of constituents or more. However, interpreting substance compositions from GCxGC data is costly and requires expertise. To...
Petroleum refinery effluent contribution to chemical mixture toxic pressure in the environment

Petroleum refinery effluent contribution to chemical mixture toxic pressure in the environment

Nov 4, 2022

Petroleum refinery effluents (PRE) are wastewaters from industries associated with oil refining. Within Europe, PREs are regulated through local discharge permits and receive substantial treatment before emission. After treatment, PREs can still contain low levels of...
Assessment of Chemical Oxygen Demand/Total Organic Carbon (COD/TOC) ratios in refinery effluents

Assessment of Chemical Oxygen Demand/Total Organic Carbon (COD/TOC) ratios in refinery effluents

Sep 15, 2022

Report no. 16/22: Chemical Oxygen Demand (COD) analysis is one of the most commonly used analytical methods to indirectly measure organic pollutants in effluent waters. The standard COD methods use potassium dichromate which is restricted under the REACH regulation....
PetroRisk version 8.01: Improved model for performing REACH Environmental Risk Assessments on petroleum substances

PetroRisk version 8.01: Improved model for performing REACH Environmental Risk Assessments on petroleum substances

Sep 6, 2022

Concawe has updated the PetroRisk model used to calculate the environmental risk assessments (ERAs) for petroleum substances needed for REACH registration dossiers. The updates result in a model which is (1) faster, (2) more transparent, (3) better aligned with the...
A novel approach for assessing the biodegradability of constituents in petroleum substances

A novel approach for assessing the biodegradability of constituents in petroleum substances

Sep 6, 2022

Petroleum substances contain hundreds to thousands of constituents, making it very difficult to generate biodegradation data on all of those constituents individually. Concawe is undertaking a novel project with SINTEF—one of Europe’s largest independent research...
