[Characteristics and Influencing Factors of Greenhouse Fluxes from Urban Lawn].

As an important component of urban green spaces, greenhouse gas uptake or emissions from urban lawns cannot be ignored. However, studies of greenhouse gas fluxes from subtropical urban lawns are relatively sparse. The static chamber-gas chromatography method was applied to monitor the ground-air exchange fluxes of various greenhouse gases(CO, CH, NO, and CO) in typical urban lawns of Hangzhou City.

[Monitoring of atmospheric CH, CO, CO, NO and SF using three-channel gas chromatography].

China is approaching a critical period of carbon peak and carbon neutrality. To assess the impact of carbon peak and carbon neutrality measures, an accurate understanding of the variations of the spatial and temporal distribution of greenhouse gases is crucial. Gas chromatography, a classical approach for greenhouse gas observation, can be employed for the high-precision analysis of partial greenhouse gases.

Methane emission via sediment and water interface in the Bohai Sea, China.

Sediment is recognized as the largest reservoir and source of methane (CH) in the ocean, especially in the shallow coastal areas. To date, few data of CH concentration in sediment have been reported in the China shelf seas. In this study, we measured CH concentration in sediment and overlying seawater columns, and conducted an incubation experiment in the Bohai Sea in May 2017.
