Περίληψη

Αιωρούμενα σωματίδια PM10 συλλέχθηκαν από το λιγνιτωρυχείο της Καρδιάς (Ιούλιος 2009), το δώμα του κεντρικού κτιρίου του ΤΕΙ Δυτικής Μακεδονίας (Δεκέμβριος 2010) και το κέντρο της πόλης της Κοζάνης (Αύγουστος 2005). Η ορυκτολογική σύσταση και η περιεκτικότητα σε άμορφα υλικά προσδιορίστηκαν με την μέθοδο περιθλασιμετρίας ακτίνων Χ κόνεως. Όλα τα δείγματα περιέχουν άμορφα υλικά (43-66 %κ.β.), ασβεστίτη (13-37 %κ.β.), μαρμαρυγίες + αργιλικά ορυκτά (4-9 %κ.β.) και χαλαζία (2-8 %κ.β.), ενώ σε τρία δείγματα ανιχνεύθηκαν άστριοι (2-11 %κ.β.). Ο ανυδρίτης, ο οποίος είναι ένα συστατικό της ιπτάμενης τέφρας και της τέφρας εσχάρας, ανιχνεύθηκε (6 %κ.β.), μόνο σε ένα δείγμα από την περιοχή του ορυχείου Καρδιάς. Η γύψος ανιχνεύθηκε, στο ορυχείο Καρδιάς (2 και 3 %κ.β.), στο κέντρο της πόλης της Κοζάνης (8 %κ.β.) στο δώμα του κεντρικού κτιρίουτου ΤΕΙ Δυτικής Μακεδονίας (13 και 14 %κ.β.). Η γύψος είναι ένα συστατικό του εξορυσσόμενου λιγνίτη, της τέφρας καπναερίων και της σκόνης της Σαχάρας. Αυτό εξηγεί τις υψηλότερες συγκεντρώσεις της γύψου στην περιοχή του ΤΕΙΔΜ στις 1 και 2 Δεκεμβρίου 2010, όπου αναφέρθηκε η επιρροή της σκόνης από τη Σαχάρα στα επίπεδα αιωρούμενων σωματιδίων στη Δυτική Μακεδονία.
