Abstract

U ovom radu opisana je potreba za mjerenjem koncentracije lebdećih čestica u zraku. Preneseni su zahtjevi zakonodavne regulative te tehničke smjernice relevantnih normi. Opisane su danas korištene metode mjerenja koncentracije lebdećih čestica, s fokusom na metodu raspršenja laserske svjetlosti. Izvršeno je istraživanje s ciljem provedbe studije ekvivalencije kandidat metode (automatskog mjernog sustava) s referentnom metodom, kako bi se potvrdile tražene radne značajke kandidat metode. Studija ekvivalencije provedena je za PM2,5 i PM10. Rezultati obje metode obrađeni su regresijskom analizom, iz koje proizlazi linearna ovisnost rezultata. Utvrđene su kalibracijske funkcije kojima se korigiraju rezultati AMS-a, te je izvršena procjena mjerne nesigurnosti.

Abstract (english)

In this paper, the need for measurement of particulate matter in ambient air is described. Requirements set by the legislative regulations, as well as the technical guidelines given by the relevant standards, are quoted. Methods for determination of particulate matter in ambient air are described, with special attention to the light scattering method (optical method). Research was conducted with a view to demonstrate equivalence of the candidate method (automated measurement system) to the reference method. The equivalence study is conducted for both PM2,5 and PM10 measurement. Results of both methods are processed using a regression analysis, which provides a linear correlation between the results. Calibration functions for both particle sizes are calculated and used to calibrate AMS results. In the end, a measurement uncertainty assessment is conducted.
