Fish fingerprints - signatures of oil contamination

该项目旨在将原油的化学特性与活生物体中的无机和有机标志物结合起来。由于石油在环境中的性质不断变化，将对生态系统的有害影响与接触泄漏原油联系起来仍然是一项重大挑战。该项目将使鱼类接触一系列新鲜/风化油，以模拟各种接触情况。石油代谢物的过渡将在一套环境和生物基质中使用多维色谱/质谱，痕量金属和化合物特定的同位素分析。这一项目将通过提高将源油与活生物体中的特定标志物联系起来的能力而带来重大惠益。

The project aims to integrate chemical characterisation of crude oil with inorganic and organic markers in living organisms. Linking harmful effects on ecosystems with exposure to spilled crude oil remains a major challenge due to the ever-changing nature of oil in the environment. This project will expose fish to a range of fresh/weathered oils to mimic various exposure scenarios. The transition of oil to metabolites will be characterised in a suite of environmental and biological matrices using multi-dimensional chromatography/mass spectrometry, trace metals and compound-specific isotope analyses. This project will provide significant benefits by providing an improved capacity to link source oil with specific markers in living organisms.
