20.500.12556/DKUM-41899 DOLOČANJE VSEBNOSTI TEŽKIH KOVIN V EMISIJAH Z MASNO SPEKTROMETRIJO Z INDUKTIVNO SKOPLJENO PLAZMO DETERMINATION OF HEAVY METALS WITH MASS SPECTROSCOPY USING INDUCTIVELY COUPLED PLASMA Zaradi omejenih izpustov nezaželenih snovi v zrak se morajo v skladu z zakonodajo izvajati meritve, ki služijo kot poročilo Agenciji Republike Slovenije za okolje. Preko nepremičnih virov onesnaževanja se v kemijski industriji v zrak izpuščajo prav tako nekatere kovine, katerih koncentracija je omejena, zato jo je potrebno kontrolirati. Merili smo koncentracijo izbranih kovin na območju tovarne Talum d.d. Z mikrovalovnim razklopom smo pričeli optimizacijo analiznega postopka, nato je sledila ICP-MS analiza. Iz izmerjenih meritev smo določili nekatere parametre validacije. Dodatno smo preverili še rezultate meritev, ki so bili izmerjeni tako v podjetju Talum Inštitut, d.o.o. kot na Zavodu za zdravstveno varstvo v Mariboru, in jih medsebojno primerjali. Rezultati kažejo, da je vpeljana metoda natančna in točna za večino izbranih kovin, kar torej ustreza standardom validacije. Primerjalna analiza je pokazala podobnost meritev pa tudi nekatera odstopanja. Certain air pollution measurements need to be carried out due to the limited allowance of releasing the unwanted substances into the air, which must be in accordance with the law. These measurements serve as a report to the Slovenian Environment Agency. Stationary sources of pollution in the chemical industry also cause some metal emissions that must be controlled because of the limited allowances of releases. We measured the concentration of selected metals at the Talum factory area. With microwave digestion, we started the optimization of the analytical procedure, followed by ICP-MS analysis. Based on these measurements, we determined some parameters of validation. Additionally, we examined and compared the results of measurements, which were made in both the Talum’s Institute, and the Institute of Public Health Maribor. The results showed that the introduced method is precise and accurate for the majority of selected metals, which therefore corresponds to the standards of validation. Comparative analysis showed resemblance of measurements as well as some deviations. emisije kovine induktivno sklopljena plazma ICP-MS emissions metals inductively coupled plasma ICP true true false [K.
