DO concentrations will also depend on the photosynthetic rate and therefore on nutrient concentrations.
This may explain the increases in decay rates with increased pH and DO concentrations.
In contrast, the lowest DO concentrations were reported for sites S1 and S2.

In addition, low DO concentrations also mobilize the trace metals (Murphy 2007).
The dissolved iron, manganese, ammonia and DO concentrations were positively correlated with the first canonical axis.
We apply these coupled transport models to characterize the distribution of DO concentrations within the hyporheic zone.
We determined the iron, manganese, ammonia and DO concentrations in Songbei WTP during 30 days stable operation (Fig. 1).
Figure 5 Mean DO concentrations at the sampling points during high and low tide in different seasons.
Mortality can occur when DO concentrations become lower than 2 mg/L for more than 2 3 days consecutively (Chervinski 1982).
