Διερευνήθηκε, η περιβαλλοντική γεωχημεία λιγνιτών, ενδιάμεσων στείρων, ιπτάμενης τέφρας και τέφρας εσχάρας, από την περιοχή της Πτολεμαΐδας. Οι χημικές αναλύσεις των κύριων στοιχείων, σε συνδυασμό με το SEM-EDS, έδειξαν ότι τα στοιχεία Si, Ca, και Fe είναι τα πιο άφθονα και συνδέονται με διάφορα μικρο σωματίδια. Κατά μέσο όρο, τα πιο άφθονα ιχνοστοιχεία στα δείγματα των λιγνιτών είναι Ba (128 ppm), V (123 ppm), Cr (108 ppm), Sr (107), Ni (43 ppm), στα δείγματα των ενδιάμεσων στείρων Ba (209 ppm), Sr (209 ppm), Cr (104 ppm), Ni (76 ppm), Zr (67 ppm), Zn (57 ppm), V (53 ppm), στα δείγματα των ιπτάμενων τεφρών Ba (455 ppm), Sr (336 ppm), Ni (180 ppm), Cr (160 ppm), V (110 ppm), Zr (102 ppm), Zn (74 ppm), Cu (71 ppm), Rb (62 ppm) και στα δείγματα των τεφρών εσχάρας Ba (250 ppm), Cr (214 ppm), V (174 ppm), Sr (153 ppm), Ni (105 ppm), Zr (56 ppm), Zn (40 ppm) (EL)
The environmental geochemistry of lignite, intermediate sterile, fly ash and bottom ash samples from Ptolemais area, has been investigated. The chemical analyses of major elements, combined with SEM-EDS, showed that Si, Ca and Fe, are the most abundant elements and associated with various micro-particles. On average, the most abundant trace elements in the lignite samples are Ba (128 ppm), V (123 ppm), Cr (108 ppm), Sr (107), Ni (43 ppm), in intermediate sterile samples Ba (209 ppm), Sr (209 ppm), Cr (104 ppm), Ni (76 ppm), Zr (67 ppm), Zn (57 ppm), V (53 ppm), in fly ash samples Ba (455 ppm), Sr (336 ppm), Ni (180 ppm), Cr (160 ppm), V (110 ppm), Zr (102 ppm), Zn (74 ppm), Cu (71 ppm), Rb (62 ppm) and in bottom ash samples Ba (250 ppm), Cr (214 ppm), V (174 ppm), Sr (153 ppm), Ni (105 ppm), Zr (56 ppm), Zn (40 ppm) (EN)
