Περίληψη

Κατά την διάρκεια ενός ημερολογιακού έτους (Μάρτιος 2004-Φεβρουάριος 2004), αρκετά φίλτρα συλλογής αιωρούμενων σωματιδίων λήφθηκαν από επτά θέσεις δειγματοληψίας στην γεωλογική λεκάνη Αμυνταίου-Πτολεμαΐδας-Κοζάνης. Πραγματοποιήθηκε ανάλυση των αιωρούμενων σωματιδίων με χρήση του «Περιβαλλοντικού» Ηλεκτρονικού Μικροσκοπίου (ESEM). Ταυτόχρονα, προσδιορίστηκε η χημική σύσταση των σωματιδίων με χρήση του συστήματος διασποράς ενέργειας (EDX). Τα σωματίδια ταξινομήθηκαν σε διάφορες κατηγορίες με βάση την προέλευση τους (ανθρωπογενή, γεωγενή, βιογενή), το μέγεθος τους (μέση διάμετρος 5-20 μm), τη μορφολογία τους (γωνιώδη, ασύμμετρα, σφαιρικά, επιμήκη) και τη σύσταση τους (αργιλοπυριτικά, ανθρακικά, οξείδια, θειικά, μεταλλικά, ανθρακούχα). Δόθηκε έμφαση σε σωματίδια ιπτάμενης τέφρας που προέρχεται από την καύση των λιγνιτών στους θερμοηλεκτρικούς σταθμούς της περιοχής. Δημιουργήθηκε μία βάση δεδομένων με χαρακτηριστικά αιωρούμενα σωματίδια (όπως αυτά προσδιορίστηκαν στην παρούσα μελέτη), με σκοπό να βοηθήσει παρόμοιες μελλοντικές έρευνες στην περιοχή
