Abstract

Abstract

The samples of air and water in the Liaohe Estuary in China were collected in spring and summer. The static head space and gas-chromatography method was employed to determine the concentrations of nitrous oxide in air and in seawater. The result showed a temporal and spatial characteristic of distribution of nitrous oxide dissolved in water. The result showed that the concent rations of dissolved nitrous oxide in water were higher in spring than that in summer. The concentrations of dissolved nitrous oxide in the Liaohe River were higher than in coastal area. There was a notable negative correlation between the concentrations of N₂O and DO dissolved in the seawater Nitrous oxide dissolved in water was supersat urated in all surface water that was sampled in May and August Nitrous oxide released from water to air,and the Liaohe Estuary area represented a source of atmosphere nitrous oxide during the study period.
