Assessment of so2 Monitor

1. Introduction. Typical annual average concentrations of ambient sulfur dioxide, as of 2005, have ranged from 9 - 35 µg/m 3 in North America, 8 - 36 µg/m 3 in Europe, 40 - 70 µg/m 3 in Latin America, 10 - 100 µg/m 3 in Africa and 20 - 200 µg/m 3 in Asia [1] . Atmospheric SO 2 is primarily the result of anthropogenic activities associated with the burning of fossil fuels and industrial ...

  • Volcano Watch: New assessment of Kilauea’s extreme SO2

    May 31, 2020We knew that more than 15,000 t/d of SO2 were being emitted, but it was hard to say just how much more. Luckily, the spectrometer measures UV light over a range of wavelengths. Normally, with low SO2 emissions, we examine wavelengths where SO2 absorption is significant, which allows us to detect even very small amounts of gas.

  • A Quantitative Assessment of Sulfur Dioxide Emission

    A quantitative assessment of the rate of emission of atmospheric pollutants is essential for designing and enforcing air quality control policies. For proper evaluation of the intensity and magnitude of SO2 pollution (in a region or a country) quantitative information on the SO2 emission is needed. In this paper an attempt has been made to

  • Evaluation of a transcutaneous carbon dioxide monitor in

    The level of agreement between PaCO 2 - PtCO 2 and SaO 2 - SpO 2 was assessed by Bland-Altman analyses. Results : Both, SaO 2 from blood gas analysis and SpO 2 from the transcutaneous monitor, and PaCO 2 and PtCO 2 were equally useful. No measurements were outside of the acceptable clinical range of agreement of ± 7.5 mmHg.
