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 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...
To improve the persistence assessment of petroleum substances, Concawe started a testing programme for several hydrocarbons. Ready biodegradability tests were proposed on six 3-ring polycyclic aromatic hydrocarbons (PAHs), in accordance with the OECD 301 F protocol....
Report no. 5/22: LNAPL stands for “Light Non-Aqueous Phase Liquids” or hydrocarbons that exist as a separate undissolved phase in the subsurface at some sites with legacy releases of fuels. They are referred to as “Light” because most petroleum hydrocarbons are less...
Many factors affect the biodegradation kinetics of chemicals in test systems and the environment. Empirical knowledge is needed on how much test temperature, inoculum, test substances and co-substrates influence the biodegradation kinetics and microbial composition in...
