Abstract

Accurate and reliable air polluttants measurements are widely required all over the world. Measurement science is something of vital importance to all of us. The monitored polluttants, the measurement methods, the limit values, the laert thresholds nd the criteria for locating and monitoring points have been established by national legislation on the protection of the atmoshere and meet the requirements stipulated by EU regulations. The paper presents the colclusions which have been drawn using statistical inference tools, based on the data collected during measurements of few air polluttants CO, SO2, NOx. Measurements were collected for a period of 3 months, 10 days/month, using gas analyzers configures with NDIR (Non-Dispersive Infrared Absorbtion) sensors. Additionally, basd on experience, the paper describes, step by step, an example of uncertainty budget evaluation of SO2 for measuring air polluttants.
