Abstract. Many factors are known to influence greenhouse gas emissions from coastal wetlands, but it is still unclear which most important under field conditions when they all acting simultaneously. The objective of this study was assess the effects water table, salinity, soil temperature and vegetation on CH4 ecosystem respiration (Reco) five wetlands in Liaohe Delta, Northeast China: two Phragmites australis (common reed) Suaeda salsa (sea blite) marshes a rice (Oryza sativa) paddy. Throughout growing season, were net sinks whereas paddy sources emitting 1.2–6.1 g m−2 yr−1. emitted per unit area relative CO2. main controlling for temperature, organic carbon salinity. emission accelerated at high constant (or managed) tables decreased below surface. High temperatures enhanced emissions, rates consistently low (< 1 mg h−1) < 18 °C. At salinity levels > ppt, always probably because methanogens out-competed by sulphate-reducing bacteria. Saline can, however, emit significant amounts as produced deep layers transported through air-space tissue plants atmosphere. can be reduced creating fluctuating tables, including surface, well occasional flooding high-salinity water. management schemes biological communities must, carefully studied prior order avoid undesirable wetland communities.

Abstract Natural source zone depletion ( NSZD ) has emerged as a practical alternative for restoration of light non‐aqueous phase liquid (LNAPL) sites that are in the later stages their remediation lifecycle. Due to significant research, conceptual model evolved dramatically recent years, and methanogenesis is now accepted dominant attenuation process (e.g., Lundegard Johnson ; Ng et al. ). Most methane generated within pore space adjacent LNAPL (Ng from where it migrates through unsaturated Amos Mayer ), oxidized. While great progress been made, there still some important gaps our understanding . measurements provide little insight on which constituents actually degrading; unclear rate‐limiting factors can be manipulated increase rates; how longevity bulk its key predicted. Various threads literature were pursued shed questions listed above. Several processes may influence or measurement identified: temperature, inhibition acetate buildup, protozoa predation, presence electron acceptors, volatile hydrocarbons, alkalinity/pH, availability nutrients all affect rates, while such moisture content soil type measurement. The methanogenic appears have sequenced utilization chemical classes present due varying thermodynamic feasibility, biodegradability, effects inhibition, but rate remain quasi‐zero order. A simplified version reactive transport presented by potential useful tool predicting fractions, , more work needed obtain input parameters biodegradation rates any inhibitions.

Engineered and monitored sanitary landfills have been widespread in the U.S. since passage of Clean Water Act (1972) with additional controls under RCRA Subtitle D (1991) Air Amendments (1996). Concurrently, many common perceptions regarding landfill biogeochemical microbiological processes estimated rates gas production also date from 2-4 decades ago. Herein we summarize recent application modern tools as well metadata analysis using California, USEPA international data to outline an evolving view biogeochemical/microbiological rates. We focus on because these are uniformly subject stringent national state requirements for design, operations, monitoring, reporting. From a perspective, anoxic conditions methanogenesis rapidly established after daily burial waste cover soil, >1000 thicknesses up >100m form large ubiquitous group dispersed 'dark' ecosystems dominated by anaerobic microbial decomposition pathways food, garden waste, paper substrates. review past findings ecosystem processes, reflect potential impact that sequencing technologies (e.g., high throughput platforms) could this area research. Moreover, due ever composition landfilled reflecting transient societal practices, consider unusual known or suspected occur settings, posit areas research will be needed coming decades.
