摘要：

A quick and inexpensive protocol based on gas chromatography was used to identify and measure environmental concentrations of microbial polyhydroxyalkanoates, PHAs. Samples taken from apparently unpolluted sites characterised by agricultural land or native vegetation possessed concentrations ranging from 0.12 to 0.40 mg PHA per g sample. In contrast, environments impacted by anthropogenic activity displayed concentrations 14 to 40 times higher. The results support the suggestion that PHAs could be used as pollution bioindicators in preliminary assessments of environmental health.
