Summary Plastic pollution is a long-standing ubiquitous issue. Global use of plastics is continuing to rise, and there is increasing interest in understanding the prevalence and risk associated with exposure of wildlife to plastics, particularly in t

The presence of the C30 sterol gorgosterol (22,23-methylene-23,24-dimethylcholest-5-en-3s-ol) and its analogues in some marine and freshwater environments is generally associated with invertebrate animals or dinoflagellates since there have been no r

The sources of organic matter (OM) in surface sediments from Wilson Inlet, an enclosed and seasonally barred inlet in Western Australia, have been determined using a combination of lipid biomarkers (including fatty acids, sterols, phytol, long chain

The presence of long-chain polyunsaturated fatty acids (PUFA; ca. 9% of total fatty acids) in marine sediments near Dover, southern Tasmania, Australia prompted a search for their likely source. Analysis of a number of different species of benthic fa

We have measured the stable carbon isotopic composition of bulk organic matter (POC), alkenones, sterols, fatty acids, and phytol in the coccolithophorid Emiliania huxleyi grown in dilute batch cultures over a wide range of CO2 concentrations (1.1–

Very-long-chain (C28) highly unsaturated fatty acids (VLC-HUFA), octacosaheptaenoic acid (28:7(n-6)(4,7,10,13,16,19,22)) and octacosaoctaenoic acid (28:8(n-3)(4,7,10,13,16,19,22,25)) were identified in seven marine dinoflagellate species: Prorocentru

Resin acids in effluent from a paper mill situated on the upper Derwent Estuary near Hobart, Tasmania (Australia) were determined by HPLC analysis of their 7-methoxycoumarin-4-yl and 7-acetoxycoumarin-4-yl methyl esters. Total concentrations ranged f

Complex distributions of hydrocarbons occur in most aquatic sediments. Total concentrations can range from a few parts per million in non-polluted intertidal and oceanic areas to parts per thousand in heavily contaminated estuarine, lake and near-sho
