“…In these lakes, maxima of SRP and NH 3 -N concentrations along with sharp drops of NO 3 -N concentration can be observed in the summer due to a high microbial activity in the muddy sediments (Kleeberg & Kozerski 1997) and to the consequent decrease of oxygen concentration (Van Luijn et al 1999, Carvalho 1994. Sporadic high NO 2 -N concentrations usually occur when a large amount of fresh and easily degradable organic matter is mineralized (Colliver & Stephenson 2000, Leu et al 1998, Burns et al 1995. Accordingly, the presence of dead fishes in July 1997 and May 1999 could explain the high nitrite concentration detected in these months so as in November 1997 when a abundant degradable organic matter due to the large summer fish kill was leaky still present.…”

We present the results of a four-years monitoring program of Lake Duchessa, a small shallow subalpine lake situated at 1788 m a.s.l. in central Apennines (Italy). From 1997 to 2000, during snow free periods, we regularly measured conductivity, pH, macrophyte cover and water transparency. Contemporarily, 4 water samples were collected to determine nutrient (NH 3 -N, NO 2 -N, NO 3 -N and PO 4 -P) and phytoplanktonic chlorophyll a concentrations. Taxonomic compositions of aquatic macrophytes, zooplankton and macroinvertebrates were also determined. Inter-and intra-annual variation of water chemistry and phytoplankton biomass were addressed. Lake Duchessa showed some limnological aspects proper to lowland eutrophic situations due to livestock grazing in the watershed pastures and watering in the lake. In particular, nutrient concentration and phytoplankton biomass reached extremely high values, and lake community was relatively poor. However, despite the high nutrient loading, phytoplankton biomass collapsed in August 1997. In the same occasion, lake water became transparent and remained clear until the end of 1999. The occurrence of this clear water phase and its surprising span may be related to the reduction of tench population (due to a natural fish kill observed during the study) and to the extension of Potamogeton pectinatus L. and Myriophyllum spicatum L. cover. Our results support early observations that water transparency (i.e. environmental quality) of eutrophic shallow lakes can be improved also when nutrient loading is not reduced. Many of the Apennine lakes and ponds situated at high altitudes show conditions similar to those of Lake Duchessa. Therefore this study highlights the ecological processes to be considered in a reliable management of these freshwater systems.

“…The reason for this strong focus on ammonia oxidation is mainly related to several studies from the last century where the oxidation of ammonia has been considered as rate limiting for the whole process of nitrification (Prosser, 1989). Main findings from that time include varying copy numbers of AOB (Phillips et al, 2000) and nitrite concentrations below the detection limit in many soil samples (Burns et al, 1995), indicating that once nitrite is formed it can be quickly oxidized to nitrate. During that time, the existence of ammonia-oxidizing archaea (AOA) was not proven and ammonia oxidation in soil was thought related to some proteobacteria.…”

In a field experiment, the impact of repeated application of the antibiotic sulfadiazine (SDZ)-contaminated pig manure was assessed on functional microbial communities involved in ammonia and nitrite oxidation in the root-rhizosphere complexes (RRCs) of diverse plants composing a pasture. We surveyed the abundance of ammonia-oxidizing archaea (AOA) and bacteria (AOB) as well as Nitrobacter- and Nitrospira-like nitrite-oxidizing bacteria (NOB) by quantitative PCR (qPCR), and the diversity of amoA AOA and Nitrobacter-like nxrA amplicons using a cloning-sequencing approach. Whereas the first SDZ-contaminated manure application caused only slight effects on the investigated microbial communities and did not change the diversity and abundance pattern significantly, the second application of SDZ-contaminated manure induced an up to 15-fold increased ratio of AOA:AOB and a reduction of nrxA genes. The diversity of AOA amoA increased after the second application of SDZ-contaminated manure compared to the control treatment whereas a clear reduction of nrxA OTUs was visible in the same samples. The results indicate that the application of SDZ may principally affect nitrite oxidation by NOB and alternative pathways like nitrite reduction might be favored under these conditions.

“…To our knowledge, no water quality study in agricultural environment in Québec or Canada has ever reported a problem related to nitrite occurrence and variability in freshwater. In contrast to Canada, United States, and Australia, many European studies have reported over the last 25 years a critical situation for several polluted rivers (Meybeck 1982;Smith and Steward 1989;Burns et al 1995;Smith et al 1995;Kelso et al 1997;Smith et al 1997;von der Wiesche and Wetzel 1998). Meybeck (1982) has reported nitrite values from 0.008 to 0.017 mg N L −1 in the Rhone and Rhine rivers (Switzerland).…”

“…Meybeck (1982) has reported nitrite values from 0.008 to 0.017 mg N L −1 in the Rhone and Rhine rivers (Switzerland). In 1991, Burns et al (1995) observed nitrite concentrations ranging from 0.004 to 0.172 mg N L −1 in the six major rivers of the Lough Neagh catchment (North Ireland). In the same catchment, Smith et al (1995) reported mean concentrations varying between 0.034 and 0.064 mg N L −1 during 1991 and 1992.…”

This study is the first to report nitrite occurrence and variability in surface water across an agricultural watershed in the province of Quebec, Canada. Nitrite (NO 2 − ) concentrations were monitored across a 2.4 km 2 watershed during 2 years. Water samples were collected at the outlet from April to November and in three contrasted stream branches (six stations) during three hydrological regimes (summer low water levels, fall recharge, and snowmelt). Our study clearly demonstrates that NO 2 − levels observed at the outlet are not representative of NO 2 − variability across the micro-watershed. Surface water collected in cropped areas presents high NO 2 − concentrations during summer low water levels, often exceeding guidelines for aquatic life, with NO 2 − means ranging from 0.022 to 0.107 mg N L −1 and maximum value reaching 0.156 mg N L −1 . Furthermore, the two stream branches in cropped area have demonstrated significant differences in NO 2 − concentrations and other water quality parameters. The importance of groundwater discharge to streams in the microwatershed Bras d'Henri may potentially generate different in-stream sources of NO 2 − and water quality parameters. However, further studies are essential to determine sources and processes related to in-stream NO 2 − peaks.
