Emission von Kohlenmonoxid aus gefluteten Reisfeldern in die Atmosphäre
Abstract
The emission of carbon monoxide was studied in Italian paddy fields using the static box technique. The results indicate that CO is produced in the submerged anoxic paddy soil. CO is released into the atmosphere predominantly by plant-mediated transport and to a lesser extent by ebullition. The total amount of CO released from the submerged soil is estimated to be approximately 0.2 Tg a E-1 which is three orders of magnitude lower than the release of CH4. CO was also produced by a light-dependent reaction in the phyllosphere of the rice plants. The corresponding CO emission rate was approximately twice that due to the release from the paddy soil and thus may be of the order of 0.5 Tg a E-1. (IFU)
