- Dilema o smrti Velikega Vojvode Mirka
Petrovi}a (1820-1867), ~lana slavne ~rnogorske
dinastije Njego{, je bila prisotna vse
od njegove smrti do danes. Pri razjasnitvi tega
vpra{anja smo sodelovali z elementno analizo
(z uporabo ICP-AES in ICP-MS) vzorcev las
Mirka Petrovi}a in {e nekaterih ~lanov dinastije
Njego{. Rezultati {tudije so pokazali, da vzrok
njegove smrt verjetno ni bila zastrupitev,
ampak je nastopila zaradi bolezni (kolera).
- V okviru aplikativnega projekta (z EIMV in
TE[) smo v sodelovanju s prof. Bernerjem (IEP,
Dunaj) zasnovali sistem za vzor~evanje delcev
na izvoru (dimnik). Osnova sistema je nizkotla~ni
kaskadni impaktor, ki lo~uje delce glede
na njihovo velikost v deset velikostnih
razredov (0,015-16,0 µm), in je prilagojen
meritvam pod ekstremnimi pogoji (visoke
temperature in vlaga ter koncentracija
delcev). S tem sistemom smo nato opravili
prve meritve emisij trdnih delcev na dimniku
TE[ (blok 4, na vi{ini 50 m, Slika 1).
Vzporedno smo izpeljali tudi meritve imisij
na dveh izbranih lokacijah, ki sta razli~no
oddaljeni od izvora. Zbranim depozitom
delcev smo dolo~ili masno porazdelitev in jih
kemijsko okarakterizirali (dolo~itev elementov
pomembnih kot sledilci).

Specialni sistem za vzor~evanje aerosolskih delcev po
velikosti (0,015 – 16 mm) na izvoru emisije. Prve
meritve emisije delcev na dimniku Termoelektrarne
[o{tanj (blok 4, na vi{ini 50 m) so bile izvedene junija
2005.

- The uncertainty about the cause of death of
Duke Mirko Petrovi} (1820-1867), a member
of a famous Njego{ Dynasty of Montenegro,
existed from his death till now. In order
to elucidate whether or not he died of
natural causes we performed an elemental
analysis study (using ICP-AES and ICP-MS) on
samples of his hair, and also on hair samples
of some other members of the Njego{ family.
The results of this study suggested that
he was not poisoned but rather died of a disease
(cholera).
- In the frame of an applied research project
(with EIMV and TE[) we designed, in cooperation
with Prof. Berner (IEP, Vienna), a special
system for sampling aerosol particles directly
at the source of emission. The system
is based on a low-pressure cascade impactor,
which allows size-segregated sampling of
particles in the range 0.015-16.0 µm, and
can operate under extreme conditions (high
temperature, humidity and particle concentrations).
Using such a system we performed
measurements of emission of aerosol particles
at the stack of TE[ (Block 4, at the height
of 50 m, Figure 1) as well as sampling at two

preliminary measurements of emission of particles at

the height of 50 m).
