Abstract:
The gas-phase atmospheric degradation of prosulfocarb (a widely used thiocarbamate herbicide in winter cereals) at different NOx concentrations was investigated at the large outdoor European PHOtoREactor (EUPHORE) in Valencia, Spain. Photolysis under sunlight conditions and reaction with ozone were shown as unimportant. The rate constant for the reaction of prosulfocarb with OH radicals was determined as k = (2.9 ± 0.5) × 10-11 cm3 molecule-1 s-1 at 288 ± 10 K and atmospheric pressure by a conventional relative rate method. Significant ozone and aerosol formation was observed following the reaction of prosulfocarb with OH radicals, and the main detected carbon-containing gas-phase products were benzaldehyde, S-benzyl formyl(propyl)carbamothioate, and S-benzyl propanoyl(propyl)carbamothioate.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
Variation of Atmospheric Pressure
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
