2019-4-15 · SOx monitors or sulfur dioxide analyzers are used to measure the environmental concentration of sulfur dioxide in the air. Recent models use the ultraviolet fluorescence method that detects sulfur dioxide concentration in the air by irradiating ultraviolet light onto sulfur dioxides to excite SO₂ and then measure the fluorescence intensity emitted from the SO₂.

Asian traditional herbal preparations are frequently considered for the contamination with undeclared toxic or hazardous substances. The aim of this study was to determine the toxic heavy metals, pesticides and sulfur dioxide in decoctions that is a common form of final utilization in Korea. A total of 155 decoctions composed of multi-ingredient traditional herbs were randomly sampled from

Sulfur dioxide is depleted in the atmosphere either through deposition or oxidation mechanisms, the latter leading to aerosol formation. The reactive compounds can have adverse effects on surrounding environments (acid rain), air quality [Chin and Jacob, 1996], weather, clouds, and climate [Intergovernmental Panel on Climate Change, 2013].

Climate change mitigation - Wikipedia

2019-4-20 · Climate change mitigation consists of actions to limit the magnitude or rate of long-term global warming and its related effects.[2] Climate change mitigation generally involves reductions in human (anthropogenic) emissions of greenhouse gases (GHGs).[3] Mitigation may also be achieved by increasing the capacity of carbon sinks, e.g., through

Improvement of the tetrachloromercurate absorption

During the Gas‐Phase Sulfur Intercomparison Experiment (GASIE) in 1994 an analytical system for measuring sulfur dioxide mixing ratios at low parts per trillion (pptv) levels was employed. It is based on the absorption of SO 2 on a tetrachloromercurate(II)‐impregnated filter. The subsequent analysis uses a chemiluminescence reaction by
