Abstract

V diplomskem delu sem raziskal in predstavil hlapna aldehidna onesnaževala, njihove vire, vpliv na zdravje ter različne načine nižanja njihovih koncentracij v zraku. Nato sem napravil pregled literature za kvantitativno določanje formaldehida v zraku, kjer sem opisal različne tehnike vzorčenja in analiz. Najpogosteje so v uporabi pasivni vzorčevalniki na osnovi 2,4-dinitrofenilhidrazina, saj je za analizo potrebno le kvantitativno izpiranje reakcijskih produktov z vzorčevalnika ter kvantifikacija preko umeritvene krivulje s pomočjo HPLC. To metodo sem uporabil pri eksperimentalnem delu, kjer sem analiziral hlapna aldehidna onesnaževala z vzorčevalnikov, ki so bili sedem dni izpostavljeni zraku na različnih lokacijah muzeja Vasa v Stockholmu, na koncu pa sem svoje rezultate primerjal še z rezultati prvega opravljanja meritev izpred pol leta.

Secondary title: Determination of aldehyde pollutants in indoor air
Secondary abstract: In my thesis I researched and presented volatile aldehyde pollutants, their sources, health effects and different possibilities of reducing their concentration in the air. I reviewed the literature on quantitative determination of formaldehyde in indoor air and described several different techniques for sampling and analysis. The most widely used are passive samplers based on 2,4-dinitrophenylhydrazine, which require only quantitative washing of the reaction products from the sampler and quantification by HPLC. I used this method in my experiments, where I analysed different volatile aldehyde pollutants from samplers that had been exposed to air in several different locations of the Vasa museum in Stockholm for seven days. Finally, I compared my results to the ones taken from the first monitoring session six months ago.
