“…Furthermore, surface water pollution by increased ammonium levels is common in many of the rivers (MEP, 2014). Several findings of ammonium oxidizing bacteria in East China (including the NCP), as summarized by Ali et al (2013), imply that similar results to the ones at our field study might be possible also in specific parts of the NCP, where contaminated surface water recharges the GW with good hydraulic connection.…”

Fertilizer input for agricultural food production, as well as the discharge of domestic and industrial water pollutants, increases pressures on locally scarce and vulnerable water resources in the North China Plain. In order to: (a) understand pollutant exchange between surface water and groundwater, (b) quantify nutrient loadings, and (c) identify major nutrient removal pathways by using qualitative and quantitative methods, including the geochemical model PHREEQC) a one-year study at a wheat (Triticum aestivum L.) and maize (Zea mays L.) double cropping system in the Baiyang Lake area in Hebei Province, China, was undertaken. The study showed a high influence of low-quality surface water on the shallow aquifer. Major inflowing pollutants into the aquifer were ammonium and nitrate via inflow from the adjacent Fu River (up to 29.8 mg/L NH 4 -N and 6.8 mg/L NO 3 -N), as well as nitrate via vertical transport from the field surface (up to 134.8 mg/L NO 3 -N in soil water). Results from a conceptual model show an excess nitrogen input of about 320 kg/ha/a. Nevertheless, both nitrogen species were only detected at low concentrations in shallow groundwater, averaging at 3.6 mg/L NH 4 -N and 1.8 mg/L NO 3 -N. Measurement results supported by PHREEQC-modeling indicated cation exchange, denitrification, and anaerobic ammonium oxidation coupled with partial denitrification as major nitrogen removal pathways. Despite the current removal capacity, the excessive nitrogen fertilization may pose a future threat to groundwater quality. Surface water quality improvements are therefore recommended in conjunction with simultaneous monitoring of nitrate in the aquifer, and reduced agricultural N-inputs should be considered.

“…The DEMON s process is one of several available forms of single-step (in the same tank) partial nitritation-anammox designed for centrate treatment from anaerobically digested biosolids and operated as a sequencing batch reactor (SBR). While this process had been applied at approximately 30 plants in Europe, it had not been implemented elsewhere in a full scale application, primarily because of the requirements for seeding this process using biomass imported from operating facilities in Europe [49].…”

“…Subsequently, the anammox process was discovered in estuary sediments (10)(11)(12)(13)(14), river sediments (15,16), wetland sediments (17), paddy soils (18)(19)(20), and land-freshwater interfaces (21). As an environmentfriendly pathway, the anammox process has been applied in wastewater treatment systems (22,23). These reports provide insight into the biological N cycle.…”

Anaerobic ammonium oxidation with nitrite reduction to dinitrogen (termed anammox) has been reported to be an important process for removing fixed nitrogen (N) in marine ecosystems and in some agricultural and wetland soils. However, its importance in upland forest soils has never been quantified. In this study, we evaluated the occurrence of anammox activity in two temperate forest soils collected from northeastern China. With 15 N-labeled NO 3 ؊ incubation, we found that the combined potential of the N 2 production rates of anammox and codenitrification ranged from 0.01 ؎ 0.01 to 1.2 ؎ 0.18 nmol N per gram of soil per hour, contributing 0.5% to 14.4% of the total N 2 production along the soil profile. Denitrification was the main pathway of N 2 production and accounted for 85.6% to 99.5% of the total N 2 production. Further labeling experiments with 15 NH 4 ؉ and 15 NO 2 ؊ indicated that codenitrification was present in the mixed forest soil. Codenitrification and anammox accounted for 2% to 12% and 1% to 7% of the total N 2 production, respectively. Two anammox species, "Candidatus Brocadia fulgida" and "Candidatus Jettenia asiatica," were detected in this study but in very low abundance (as indicated by the hzsB gene). Our results demonstrated that the anammox process occurs in forest soils, but the contribution to N 2 loss might be low in these ecosystems. More research is necessary to determine the activities of different N 2 releasing pathways in different forest soils. IMPORTANCEIn this study, we examined the anammox activity in temperate upland forest soils using the 15 N isotope technique. We found that the anammox process contributed little to the N 2 production rate in the studied forest soil. Two anammox organisms, "Candidatus Brocadia fulgida" and "Candidatus Jettenia asiatica," were detected. In addition, we found that codenitrification was another N 2 production pathway in forest soils. Our results could contribute to the understanding of soil gaseous N losses and microbial controls in forest soils.
