AI Article Synopsis
- A study measured H2S and COS emissions from the Suaeda salsa marsh in the Yellow River estuary using a static chamber and Chromatogram method during the growth season (May to October).
- The results showed significant seasonal and diurnal variations in these emissions, with average fluxes of 4.97 µg/(m²·h) for H2S and 0.92 µg/(m²·h) for COS.
- The study identified soil sulfate (SO4²-) content and water content as the main environmental factors impacting H2S and COS emissions, suggesting that other variables like plant life and tidal conditions also play a role and warrant further investigation.
Article Abstract
The H2S and COS emission fluxes from Suaeda salsa marsh in the Yellow River estuary were measured using the static chamber and Chromatogram method during the growth season (May to October), the results showed that the seasonal and diurnal variations of H2S and COS emission fluxes were obvious, and Suaeda salsa marsh in the Yellow River estuary was the sources for both H2S and COS during the growth time, and the mean H2S and COS emission fluxes from Suaeda salsa marsh were 4.97 microg x (m2 x h)(-1) and 0.92 microg x (m2 x h)(-1), respectively. Different environmental factors had different effects on the emission fluxes of H2S and COS from Suaeda salsa marsh, in which the SO4(2-) content and water content in the soil were the main factors that affected the H2S and COS emission fluxes, respectively. Sulfur gases emissions from Suaeda salsa marsh may be affected by many factors, such as plant, tide status and so on, so that should be further studied.
