Comparative measurements between the results achieved with reference method and the optical method for determination of PM10 dusts in ambient air

The current paper aims to determine the actuality of optical method measuring PM 10 dusts powders compared reference (gravimetric method). According Integrated National Plan in field Energy and Climate Change 2021-2030, Romania must implement a program reduce impact on atmosphere, including air quality monitoring, thus leading an increase number monitoring points samples required for monitoring. Currently, dust stations use gravimetric method, consisting absorbing known volume filters weighing deposited them. As this requires minimum 3 days, it is necessary apply alternative with short response time, namely method. Parallel experimentation two devices that different principles was performed several series measurements at economic agent has obligation monitor premises borders. Results obtained from comparison can support future researchers order find limitations validate routinely.
