Što su lebdeće čestice i zašto
su bitne?
• Sve čvrste i tekuće čestice raspršene u
zraku promjera 0,002 -100µm
• Jedan su od najvažnijih pokazatelja
onečišćenja zraka
Količina lebdećih čestica u zraku ovisi o:
• smjeru i jakosti vjetra
• temperaturi zraka
• vlazi
• količini oborina
• naoblaci
• sunčevom zračenju
• stabilnosti troposfere
Istraživačka pitanja
• Zašto grad Bakar?
• Koliki je intezitet onečišćenja lebdećim
česticama u Bakru ?
• Kakav je sastav lebdećih čestica?
• Kakav je općenito utjecaj prisutnih
polutanata na zdravlje ljudi?
• Možemo li zajedno sa stanovnicima
utjecati na smanjenje količine
lebdećih čestica?
