Vsebina:

Content (Syllabus outline):

Z razvojem nanotehnologije na osnovi posebnih lastnosti nanodelcev, kot so velika mobilnost, povečana kemična aktivnost in razmerje med površino in prostornino, majhna velikost, majhna masa in spremenjene kemijske in fizikalne lastnosti, se je odprlo novo področje potencialnih tveganj za žive organizme. Poleg namerno proizvedenih nanodelcev z nanotehnološkimi procesi je naše okolje zelo onesnaženo z nenamerno proizvedenimi nanodelci z izgorevanjem, transportom in industrijskimi procesi, ki poslabšujejo kvaliteto bivanja in znižujejo življenjsko dobo. Nanodelci, ki predstavljajo veliko večino t.i. trdih delcev, ki jih podajajo v enotah PM10 in PM2.5, povzročajo bolezni srca in ožilja, nekatere vrste rakavih obolenj, astmatične napade in alergije.

Predmet podaja pregled nevarnosti nanodelcev ter metod in tehnik zaščite pred temi nevarnostmi, tudi v luči zaščite pred koronavirusi, povzročiteji pandemije COVID-19.

Predmet vključuje:
- analize nevarnosti nanodelcev v njihovem življenjskem ciklu
- redne meritve sproščanja nanodelcev in merjenje njihove kemijske sestave
- karakterizacijo lastnosti nanodelcev, vključno s potencialnimi toksičnimi učinki
- tveganja, povezana z nanotehnološkimi proizvodi
- načine zaščite na delovnem mestu in v splošnem okolju

Development of nanotechnology based on special properties of nanoparticles, i.e. a high mobility, enhanced chemical activity and surface/volume ratio, small size, small mass, and changed chemical and physical properties, has opened a new area of potential risks for living organisms. Beside intentionally produced nanoparticles by nanotechnology processes, our environment is highly polluted by non intentionally produced nanoparticles by combustion, transport and industrial processes, which deteriorate the quality of life and reduce life expectancy. Nanoparticles representing a large majority of particulate matter presented in the PM10 and PM2.5 units, cause cardiovascular diseases, certain types of cancer, asthma attacks and allergies.

The course presents an overview of the dangers of nanoparticles and methods of protection from these dangers, also in the light of protection against coronaviruses, the causes of the COVID-19 pandemic..

The course includes:
- analysis of nanoparticle’s risks in their life cycle
- monitoring and measurement of exposure to nanoparticles
- characterization of nanoparticle properties including the potential toxic effects
- risks associated with nanotehnological products
- methods of protection at the workplace and in the general environment
