Report no. 5/21: Per- and polyfluoroalkyl substances (PFAS) are a group of widely used man-made organic chemical substances. They contain alkyl groups on which all or many of the hydrogen atoms have been replaced with fluorine. As such, they contain at least one...

Improving our understanding of the environmental persistence of chemicals

May 28, 2021

Significant progress has been made in the scientific understanding of factors that influence the outcome of biodegradation tests used to assess the persistence (P) of chemicals. This needs to be evaluated to assess whether recently acquired knowledge could enhance...

Overview of Field-Based Analytical Techniques, Devices and Kits to Determine Petroleum Hydrocarbons in Soil

Apr 28, 2021

Report no. 3/21: Determination of petroleum hydrocarbons in soil has long been an area of active investigation and still attracting interest as there are important and complex environmental contaminants. Several standardised lab-based analytical techniques providing...

Conventional and high resolution chemical characterization to assess refinery effluent treatment performance

Mar 27, 2021

Refinery effluents represent an emission source of hydrocarbons (HCs) and other constituents to the environment. Thus, characterisation of effluent quality in terms of concentrations of key parameters relative to permitted standards is important and for total...

A Critical Review and Weight of Evidence Approach for Assessing the Bioaccumulation of Phenanthrene in Aquatic Environments

Feb 23, 2021

Bioaccumulation (B) assessment is challenging because there are various B-metrics from laboratory and field studies, various criteria and thresholds for classifying bioaccumulative (“B”) and non-bioaccumulative (“nB”) chemicals, and inherent variability and...
