Research interests
Steve's major interests were in the areas of organic and environmental organic geochemistry, with particular emphasis in these areas:
Origin and significance of highly branched acyclic isoprenoids (e.g. use as climate proxies, calibrants for molecular evolution etc).
Nature of unresolved complex mixtures of hydrocarbons and naphthenic acids (e.g. effects as pollutants, corrosive chemicals, pipeline blockages etc)
Fate and effects of organic pollutants especially oil pollution (e.g. effects of dispersants on toxicity and longevity of oil pollution)
Fate and effects of plastics and other hydrophobic pollutants (e.g. transport of toxic pollutants into marine organisms).
Origin and Significance of Highly Branched Acyclic Isoprenoids
The structural and stereochemical specificity conferred on many organic molecules during biosynthesis is preserved when the compounds are incorporated into sediments. Proof of the structures of such molecules (biological markers) has had such a dramatic impact on petroleum geochemistry that laboratories worldwide are now equipped with the analytical instrumentation necessary for monitoring changes in such compounds. Amongst the most valuable and widely used are a number of acyclic isoprenoid hydrocarbons. Steve's group have made significant contributions to this area including the pioneering syntheses and identifications of crocetane (methanotrophic bacteria) and haslane and rhizane(diatoms) chemical fossils.
The first synthesis and complete spectral characterisation (MS, 13C NMR) of a novel C25 isoprenoid alkane (haslane) and related haslenes was reported by Steve and John Robson in Nature (60 citations)and allowed the compounds reported, but not identified, in over fifty other studies to be assigned. Subsequently, C20 and C30 (rhizane) analogues were also synthesised and the synthetic compounds were used to afford a possible explanation of their sedimentary abundance and worldwide distribution. The research area increased further in importance to industry with the discovery of the diatom (algal) source of the compounds by Australian workers and the occurrence of haslane in crude oils. Subsequent reports resulted in continued funding which on completion, led to a postdoctoral NERC ROPA award in collaboration with Professor Jean-Michel Robert at the University of Nantes, France (report rated Scientifically Excellent by NERC reviewers 1999). Invited lectures in the U.S.A., Spain and Australia, followed by a sabbatical year at the CSIRO Marine Laboratories in Australia were accompanied by filing of two provisional patents and numerous publications, describing the uses of the alkenes as biomarkers and as potential anti-tumour agents and we recently identified all of the common sedimentary compounds (Geochimica Cosmochimica Acta) and determined the method by which they are biosynthesised (Proceeedings of National Academy of Sciences, USA with Prof Michel Rohmer of Louis Pasteur University Strasbourg). We worked with colleagues at Royal NIOZ in the Netherlands and Stanford University USA, to calibrate the pace of the evolution of haslene and rhizene-producing diatoms since the Cretaceous period (Science, 2004). Our most recent work has shown that algae (diatoms) living under sea -ice produce a unique biomarker which can be used as a chemical fossil to track the past variations in sea ice in the Arctic (Earth & Planetary Science Letters 2008) at least for the last 10,000 years and now we have shown (published in 'Antarctic Science')a related chemical can be used in the Antarctic. This is crucial to the accurate calibration of computerised climate prediction models.
Nature of Unresolved Complex Mixtures of Hydrocarbons
It is astounding, but nonetheless true, that even with sophisticated analytical tools currently available, the hydrocarbon composition of the world's major energy source, namely crude oil is, still largely unknown. Steve's report with Mark Gough in Nature 1990 (>100 citations to date, cited 1990-2005) that a considerable proportion of these previously unresolved and hence unidentified hydrocarbons could be characterised by oxidative degradation was therefore met with widespread interest. Synthesis, spectral characterisation and oxidation of some of the proposed hydrocarbons supported the conclusions of the initial studies, as did biological oxidation. Development of the methodology to include a quantitative, chemometrics-based analysis of the oxidation products also allowed the 'fingerprinting' of a variety of oils from oil spills and the method has also been applied to several unpublished oil spill incidents. The work attracted funding from British Petroleum and from the Natural Environment Research Council. The unravelling of crude oil composition has important consequences for both upstream and downstream petroleum industrial activities as well as for pollution studies. Significant in the latter respect is the increased toxicity of the UCM once oxidised. This realisation led to the funding of two further Ph.D. studentships and a postdoctoral fellow by NERC, from which numerous publications resulted including a paper delivered to the World Congress of the Society for Environmental Toxicology and Chemistry (SETAC) which won the Procter & Gamble Eurocor prize for the best lecture by a young scientist for former Ph.D. student, and post-doctoral fellow, Emma Smith who now works at the University of Toronto, Canada. Three further papers were published in Environmental Science and Technology, (see publications).The impacts of UCM pollutants on marine ecosystems were established in a preliminary study published in the Journal of Applied Ecology and we have used comprehensive gas chromatography mass spectrometry to identify thousands of overlooked toxicants in health-impacted mussels from around the UK (Environmental Science & Technology, 2007; a Most-Cited paper in 2007) and to demonstrate the toxicity of the pollutants to mussels. With an Advanced Investigators Grant from the ERC 2009-2014 we pioneered methods to identify the polar (e.g. acidic) pollutants of petroleum, often using the acids of oil sands process waters as a 'supercomplex' example (numerous papers in Environ Sci Technol 2009-14).
Studies of Organic Pollutants
Oil Pollution
Oil pollution remains a widespread environmental problem. Application of the analytical and biological marker chemistry expertise developed in the foregoing studies to the identification of crude oils spilled in the environment has proved an extremely environmentally valuable exercise over many years and has led to both published and consultancy studies. Differentiation of petroleum-derived and biogenic hydrocarbons in Mussels (Mytilus edulis) from North Sea oil platforms required a revision of previous estimates of pollutant burdens and one of the first identifications of a specific algal source for the biogenic compounds was made. Extension of this careful, compound-specific analytical approach proved valuable for the identification of Nigerian crude oil spilled into the Humber Estuary and of hydrocarbons from the Sullom Voe oil terminal. A fully funded studentship from Kuwait provided instrumentation necessary for a realistic appraisal of the role of solar radiation in the degradation of spilled oil. It is apparent that this process has not been adequately modelled by previous studies and our results indicate that if suitable attention is paid to experimental design, major differences in the degradation rates of oil-derived water-soluble aromatics are observed. The results of these initial studies were presented at an invited lecture to the British Association for the Advancement of Science (Mason lecture). Successive studies were supported by the University, NERC and Plymouth Marine Laboratory including two further studentshipsboth now completed. An important development has been extension of this approach to an examination of the toxicological importance of the compounds from crude oil. Indeed this has revealed that previous research has under estimated a significant environmental burden. This work represents one of the few U.K. studies of molecular changes in spilled oil composition despite the regular occurrence of oil spills of headline proportions (e.g. Braer, Sea Empress). Our studies of the latter have resulted in numerous publications and both research council and industry funds.
With funding from DEFRA, DTI, MMS (USA) and the Maritime & Coastguard Agency we completed a 4 year study of the toxicity effects of biodegraded and dispersed crude oils.
