对生物固体和城市污水的土地处理的研究主要集中在病原体、有毒化合物或重金属对土壤的潜在污染上。目前对污泥改良对土壤碳源和碳汇浓度的影响知之甚少。在这项研究中，使用膜入口质谱法（MIMS）在施用污泥之前、期间和之后，在3cm深度连续监测苏格兰土壤核心（石灰和未石灰地块）的气体浓度。在将污泥施用于土壤核心后，观察到CH4（持续8天）和CO2（持续16至120天）浓度显著且持续增加。这表明短期刺激本地产甲烷菌，提供新的产甲烷菌接种物，或抑制甲烷氧化剂（例如重金属或nh4污泥）。土壤微生物的发酵活性在几个月的时间内得到增强，这表现为二氧化碳浓度的升高。
Studies of the land disposal of biosolids and municipal sewage have focused largely on the potential pollution of the soil with pathogens, toxic compounds or heavy metals. Little is known about the impact of sludge amendment on carbon source and sink concentrations in soils. In this study gas concentrations in Scottish soil cores (from limed and unlimed plots) were monitored continuously at 3cm depth before, during and after sludge application using membrane inlet mass spectrometry (MIMS). Following sludge application to soil cores, significant and sustained increases in CH4(for 8 days) and CO2(for between 16 and 120 days) concentration were observed. This suggested short-term stimulation of indigenous methanogens, provision of a new methanogenic inoculum, or inhibition of methane oxidizers (for example by heavy metals or NH4in sludge). Soil microbial fermentative activity was enhanced over periods of a few months as shown by elevated CO2concentrations.
