Zusammenfassung
As and Se were determined in woodlice of the species Porcellio scaber (P. scab.) which were collected in pitfalls from a contaminated site near Jena, Thuringia, Germany. The animals were dried, ground, and digested using nitric acid combined with microwave-assisted high pressure digestion. Analysis of the samples was carried out by GFAAS with Zeeman background correction. The analytical method was developed based on two reference materials Dorm-2, Dogfish muscle (Squalus acanthias), and TORT-2, Lobster Hepatopancreas. The latter reference material was considered a close match to the matrix of the woodlice samples as both animal species are reported to store trace metals very efficiently in a particular section of their intestines: the hepatopancreas.
