Fish fingerprints - signatures of oil contamination

该项目旨在将原油的化学特征与生物体内的无机和有机标记相结合。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暴露于泄漏的原油联系起来仍然是一项重大挑战。该项目将鱼类暴露在一系列新鲜/风化油中，以模拟各种暴露情景。石油向代谢物的转变将在一套环境和生物基质中使用多维色谱/质谱，微量金属和化合物特异性同位素分析进行表征。该项目通过提高将源油与生物体内特定标记物联系起来的能力，将带来显著的效益。

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.
