“…More than 90% of all released gases in a water body are ebullition gases [36]; methane flux from the sediment-water boundary in the eutrophic pond probably was possibly close to the net release flux at the water-gas interface, although the GTD method could overestimate the net flux of methane gas because it avoids methane oxidation in the emission process in aerobic water. In this study, the nutrient concentration levels in the eutrophic pond were far above those in a eutrophic reservoir [31], wetland [34], and paddy soil [35] and were equivalent to those in some eutrophic urban ponds [8,37]. A higher nutrient load possibly contributed to the higher methane flux in the eutrophic water.…”

Water bodies are major areas for methane release. Eutrophic water bodies may promote methane flux. The sediment-water interface is the major location for methane release, and studies on sediment-water interactions are necessary to regulate methane release in water. However, relevant studies on methane flux at the sediment-water interface are limited due to methodological difficulties. Using an innovative gas trapping device, this study investigated the seasonal characteristics and diel variation in summer methane flux from eutrophic water bodies and analyzed the correlations between temperature, dissolved oxygen (DO), different forms of nitrogen and the methane flux at different time scales. The results showed that methane flux in the eutrophic pond was high and had distinct seasonal variations and diel variations: the average value was 2.81 ± 0.19 mmol m −2 h −1 in summer, which was significantly greater than that in spring (0.62 ± 0.14 mmol m −2 h −1 ), autumn (0.63 ± 0.10 mmol m −2 h −1 ) (p < 0.01) and winter (approached zero). The diel characteristics of methane flux in summer exhibited a unimodal pattern of increase at night and decrease during the day. The correlation analysis showed that the sediment-water methane flux rate of the water body was significantly positively correlated with the temperature and NH 4 + concentration and significantly negatively correlated with DO, NO 3 − and NO 2 − concentration. Meanwhile, among different time scales, the correlations between NO 3 − /NH 4 + concentration and methane flux were the highest at the diel scale in summer (R 2 = 0.68, 0.87 respectively) when the temperature and DO vibration was low and the relationship between temperature/DO and methane flux was poor (R 2 = 0.45, 0.87 respectively). This study considered that higher NH 4 + -N and lower NO 3 − -N/NO 2 − -N content in eutrophic water could have an effect on the high methane flux in summer as well as the low dissolved oxygen content.

The aim of this work was to study the efficiency of microcosms-scale floating treatment wetlands (FTWs) in the N and P removal from a synthetic runoff effluent and to evaluate the effluent tolerance of Typha domingensis. Each FTW consisted of a raft constructed with a plastic net where T. domingensis plants were installed. In order to evaluate the plant role, reactors with FTWs and without FTWs (controls) were used. P and N additions were carried out as follows: 5 mg L P (P5 and P5-control); 10 mg L N (N10 and N10-control); 5 mg L P + 10 mg L N (P5N10 and P5N10-control). Also, a biological control (B-control) without contaminant addition was used. The removal of soluble reactive phosphorus and total phosphorus were significantly higher in the FTWs than in the controls. Ammonium and nitrate concentrations were not significantly different between FTWs and controls at the end of the experiment. However, nitrate concentrations showed significant differences between FTWs and controls during the experiment. N and P were mainly accumulated in plant tissues and not in the sediment. Plants tolerated the effluent conditions and showed a positive growth rate. The use of FTWs is a promising strategy for the sustainable treatment of water bodies affected by runoff waters.

“…The changes in the water's biotope of such tanks are primarily the increase of dissolved concentrations and the involved organic matter and the change of mineralization, both qualitative and quantitative. One of the indicators investigated for the assessment of water quality, and especially for the study of changes in their mineralization, is the concentration of chloride ions [1][2][3][4][5].…”

This study investigated the possibility of using artificial neural networks to predict changes in the concentration of chloride ions in the urban ponds on the example of the inflow and outflow zones of water to and from the ponds Syrenie Stawy in Szczecin (NW-Poland). The possibility of using selected water quality indices (selected based on correlation matrix of water quality indices with Cl -), in particular: COD-Cr, BOD5, DO, water saturation by O2 and NO2 -and their influence on the chloride concentration forecast was tested.
