Resumo: | For the evaluation of PAH extraction techniques in adipose and liver tissues of marine tetrapod, samples of some species (Pontoporia blainvillei, Chelonia mydas, Thalassarche melanophris, and Balaenoptera brydei) were spiked with PAH standards and extracted using soxhlet system and microwave oven. The results of both extraction techniques for the two different tissues of the four species of tetrapod were within the quality assurance and quality control criteria, that means both extraction techniques produced acceptable recoveries for surrogate and spiked compounds added to the sample tissues. Although both techniques of extraction met quality criteria and were considered suitable for extraction of marine tetrapod tissues, the soxhlet system produced a higher recovery of the spiked compounds and a lower standard deviation between the replicates than the microwave extraction; therefore the soxhlet system was considered the more efficient extraction method for PAH. The evaluation of liver and adipose tissue PAH accumulation, as well as the influence of tissue heterogeneity, was impaired as the concentrations of PAHs in almost all samples were lower than the detection limits of the analytical method. |
