河口和沿海地区等具有生物生产力的地区，尽管只占世界海洋的一小部分，但却对甲烷和一氧化二氮的排放起着重要作用。本文综合了英国河口研究中测量的温室气体数据，强调城市污水负荷与甲烷（P< 0.001）和一氧化二氮（P< 0.005）浓度显著相关。它表明，特定的河口类型，使他们更敏感的人为影响温室气体的生产，特别是河口，经历低氧水平，由于减少混合和分层或高沉积物需氧量。值得注意的是，我们发现，高城市污水负荷的河口可能是全球温室气体的隐藏来源。综合现有的信息，温室气体浓度的概念模型在河口不同的形态和混合制度。该模型的应用应有助于识别易受人为影响的河口和温室气体排放的潜在热点。
Biologically productive regions such as estuaries and coastal areas, even though they only cover a small percentage of the world's oceans, contribute significantly to methane and nitrous oxide emissions. This paper synthesises greenhouse gas data measured in UK estuary studies, highlighting that urban wastewater loading is significantly correlated with both methane (P< 0.001) and nitrous oxide (P< 0.005) concentrations. It demonstrates that specific estuary typologies render them more sensitive to anthropogenic influences on greenhouse gas production, particularly estuaries that experience low oxygen levels due to reduced mixing and stratification or high sediment oxygen demand. Significantly, we find that estuaries with high urban wastewater loading may be hidden sources of greenhouse gases globally. Synthesising available information, a conceptual model for greenhouse gas concentrations in estuaries with different morphologies and mixing regimes is presented. Applications of this model should help identification of estuaries susceptible to anthropogenic impacts and potential hotspots for greenhouse gas emissions.
