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...
Report no. 2/20: The report details the outcome of a follow-up project of a study initiated by Concawe in 2013, investigating the occupational exposure to emissions from hot Heavy Fuel Oil (HFO) (inhalation exposure to aerosols and vapours) during inland barge loading...
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...
Reliable delineation of aquatic toxicity cut-offs for poorly soluble hydrocarbons is lacking. In this study, vapor and passive dosing methods were applied in limit tests with algae and daphnids to evaluate the presence or absence of chronic effects at exposures...
Report no. 15/20: Petroleum substances may contain polyaromatic hydrocarbons (PAHs) that can interact with sunlight. These interactions can increase hazard, via photo-enhanced toxicity, and reduce exposure, due to photodegradation. These processes are not considered...
