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

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

by Victoire de Marans | 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

by Victoire de Marans | Sep 15, 2022

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. The European...
A review of toxicity testing conducted on European refinery effluents in 2010, 2013, 2016, and 2019

A review of toxicity testing conducted on European refinery effluents in 2010, 2013, 2016, and 2019

by Victoire de Marans | Jul 15, 2022

This report provides an assessment of the extent to which toxicity testing is carried on European refinery effluents, and the types of tests being used. The analysis is based on responses given to Concawe water use and effluent quality surveys completed for the 2010,...
Qualitative and Quantitative comparison of field-based analytical technologies for petroleum hydrocarbons determination in soils

Qualitative and Quantitative comparison of field-based analytical technologies for petroleum hydrocarbons determination in soils

by Victoire de Marans | Jul 11, 2022

The performance of seven field-based technologies including 3 portable solvent-based technologies and 4 handheld solvent free technologies were evaluated for petroleum hydrocarbons determination in soil and soil-gas samples from a range of gasoline and diesel spiked...
Effects based methods (EBMs) in combination with passive sampling of refinery streams

Effects based methods (EBMs) in combination with passive sampling of refinery streams

by Victoire de Marans | Jul 8, 2022

This report provides an overview of spot and passive sampling data of three refinery effluents after treatment that were collected for chemical and ecotoxicological effluent assessment. The report includes a discussion of the relationships between toxic units derived...
