摘要: Abstract Hydrocarbon distributions in two intertidal, surface sediments from Bridgwater Bay were examined by high performance liquid chromatography (HPLC), gas (GC) and chromatography/mass spectrometry (GC-MS) to investigate sources of hydrocarbons. Two major hydrocarbon identified, pyrogenic polycyclic aromatic hydrocarbons (PAHs) a chronic petrogenic input. Other probable algal, higher-plant DDT-related pesticides. It was not possible detect contribution the nearby Liassic shale. Petrogenic biomarker broadly similar sediment samples, possibly reflecting degree resuspension mixing within Bay. However, significance some slight differences steroidal could be determined. A relatively greater source(s) than source noted finer grained sample. An extended range PAHs both with molecular weights up 326 detected. group compounds, comprising terphenyls, cyclohexylbiphenyls dicyclohexylbenzenes, detected, which appeared have origin.
