“…(2) poor water clarity; (3) rapid loss of oxygen from the hypolimnion (Matthews and Effler 2006a); (4) subsequent accumulation of reduced byproducts of anaerobic metabolism, including ∑S 2− (Effler et al 1988) and CH 4 (Addess and Effler 1996); (5) depletion of DO in the upper waters during the fall mixing period associated with the oxidation of these byproducts (Gelda and Auer 1996); and (6) exodus of fish from the lake during the fall mixing interval of years of severe DO depletion (e.g., Tango and Ringler 1996). The last two of these features are particularly severe and have been targeted by managers in the design of rehabilitation programs.…”

“…The X S" concentrations found in the littoral zone of Lake Muggelsee were rather low when compared with those of hypolimnetic zones ( BARK and GOODFELLOW, 1985;EFFLER et al, 1988;HADAS and PINKAS, 1995). Fast turnover rates and wave action removing the released sulfides towards open water may be assumed to be responsible for this relation.…”

Wave breakers, which were built in front of mechanically damaged reed significantly promote littoral accumulation and protect deposition zones from erosion. However, embankment with fagots produces a fine-grained organogenic mud towards open water. These sediments revealed significantly increased 0, consumption rates (610 mg O,h' . d) and steeper gradients of NO;, SO:-and CH., indicating intensified anaerobic reduction processes when compared with unsheltered sites. The nutrient gradients differed from those of 'natural' accumulation zones and caused diminished O2 saturation (by 30%) specially in summer months. I: S2-concentration was positively correlated to TC content of sediments and temperature and negatively to distance from shore. The annual mean concentration ranged among 10 and 51 pg S ' I and was not affected by wave breakers.

“…Error bars are the SD of the mean of three replicates Table 3 Size-fractionated rates of ammonia and NO 2 − oxidation (mean±SD) in surface water of Lake Yuehu (n=12), Lake Dianchi (n=15), and Lake Houguan (n=9) based on all the data obtained in different sampling times within each lake greatly weaken or even eliminate its inhibitory effects on nitrifying bacteria colonized on these kinds of particles. Importantly, in Lake Dianchi and Lake Yuehu, the ammonia oxidation rates were 78.4% and 74.1% particle-associated, respectively, while the NO 2 − oxidation rates were only 57.1% and 59.4%, respectively (Table 3), thereby being less protected against inhibition of high nitrogen loading, rapid loss of DO, and subsequent accumulation of reduced byproducts (Effler et al 1988). Moreover, it is clear to show that NO 2 − oxidation rates in free-living fractions accounted for very great proportion of the total NO 2 − oxidation rates in Lake Dianchi (42.9%) and Lake Yuehu (40.6).…”

Nitrification is a process in which ammonia is oxidized to nitrite (NO 2 − ) that is further oxidized to nitrate (NO 3 − ). The relations between these two steps and ambient ammonia concentrations were studied in surface water of Chinese shallow lakes with different trophic status. For the oxidations of both ammonia and NO 2 − , more eutrophic lakes generally showed significantly higher potential and actual rates, which was linked with excessive ammonia concentrations. Additionally, both potential and actual rates for ammonia oxidation were higher than those for NO 2 − oxidation in the more eutrophic lakes, while in the lakes with lower trophic status, both potential and actual rates for ammonia oxidation were almost equivalent to those for NO 2 − oxidation. This can be explained by the excessive unionized ammonia (NH 3 ) concentration that inhibits nitrite-oxidizing bacteria in the more eutrophic lakes. The laboratory experiment with different ammonia concentrations, using the surface water in a eutrophic lake, showed that ammonia oxidation rates were proportional to the ammonia concentrations, but NO 2 − oxidation rates did not increase in parallel. Furthermore, NO 2 − oxidation was less associated with particles in natural water of the studied lakes. Without effective protection, it would be selectively inhibited by the excessive ammonia in hypereutrophic lakes, resulting in NO 2 − accumulation.Shortly, the increased concentrations of ammonia cause a misbalance between the NO 2 − -producing and the NO 2 − -consuming processes, thereby exacerbating the lake eutrophication.
