| Abstract: | The sediment samples collected from Yangtze estuarine and coastal areas were extracted by Soxhlet extracting method and accelerated solvent extraction method.The extracted liquids were determined by GC/MS.The effect of extraction method and solvent on the concentration,distribution and types of extracted PAHs were analyzed.The results showed that the highest concentration of PAHs was found at Wusongkou;Soxhlet extracting method was better than accelerated solvent extraction method in the extraction efficien... |
