Maria Żmudzińska, Janusz Faber, Katarzyna PerszewskaDetermination of nitrogen oxides content in the work environment – parameters characterising the methodAbstractMethods of direct measurement of air pollution increasingly used in environmental studies are not standardised and do not meet the requirements of the applicable European standards. The article presents studies on the determination of parameters characterising the method used in the environmental measurements of the concentration of nitrogen oxides using direct measurement meters. The following parameters characteristic of this method were defined: working range, limit of quantification, accuracy, repeatability, the expanded uncertainty of the method. The determination of parameters characterising the method for the determination of nitrogen oxides content in the air at workplaces enabled the presented method to be adapted to the requirements of European standards.
