DNA damage and health effects in juvenile haddock exposed to sediment or produced water associated PAHs

The Condition Monitoring in the North Sea the last ten years have documented genotoxic effects (DNA adduct) in fish collected in areas with extensive offshore oil and gas activity. However, the source and identity of genotoxic compound has not been identified. The objective of this project has been to study the formation of DNA damage in haddock exposed to petrogenic or pyrogenic polyaromatic hydrocarbons (PAHs) from different sources: Extracts of produced water (Statfjord A); distillation fractions of crude oil from Gullfaks (representing oil based drilling mud); pyrogenic PAH This report presents all the results from the study on DNA adducts and a selection of other biological effect parameters.
