Abstract Urban constructed water quality treatment (WQT) wetlands are often applied to be integrated with ecological engineered landscaping (EEL) measures for wastewater treatments. This study aims identify the interrelationships between hydrological factors and pollutant removal contributions of typical WQT at each stage, i.e., subsurface flow (SSF), vertical (VF), free surface wetland (FSF), floating island (FWI), aeration ponds (APs), ornamental (OPs) in four parks Hangzhou, China. Water indices (WQIs) have been monitored. Interactive comparisons correlations indicators WQIs (i.e., pH, DO, NH3-N, CODCr, TP) developed, while contribution WQI was explained. It is found that stage had heterogeneous effects on due various geo-ecological factors, including hydraulic conditions, plant type, microbial microenvironment, whereas temperature waterbodies affected performances full sites all seasons. Three corresponding EEL guiding principles were derived, optimising measures, adapting planting methods, incorporating multifunctional design adaptive management. The findings will helpful improving efficacy stages as one potential ecosystem services provided by parks.

Plastic pollution in rivers threatens ecosystems, increases flood risk due to its accumulations at hydraulic structures and final emissions into the ocean threaten aquatic life, especially probably most coastal urbanized areas. Previous work suggests that plastic these urban is influenced by hydrometeorological anthropogenic factors. However, transport dynamics of plastics such are non-linear complex remain largely unresolved. Here, we show tidal can be main driver closest river mouth. Outside zone, rainfall discharge were identified more important drivers. We monitored Odaw river, Ghana during dry season. The drains densely populated city Accra discharges Gulf Guinea. Data collected between March May 2021 (dry season), using visual counting four bridges along which two located within zone. explored correlations transport, rainfall, dynamics, discharge. Finally, estimated total mass item-to-mass conversion data from previously published literature. observed a peak upstream bridge zone after an increase (7.3 times larger). found gradient factors driving transport. Closer mouth, strongly correlated with than upstream. daily was 1.4–3.8 × 10 2 kg/d, lower previous model estimates. These results add evidence inconsistent variables. Long-term monitoring required further investigate this. also support hypothesis crucial factor controlling ocean. findings provide baseline for season allow comparison wet approach adopted here serves as blueprint similar systems, regionally globally.

Variations in primary production relation to selected physicochemical and biological parameters of the Oum Er Rbia River estuary were measured monthly from November 2018 January 2020 at two stations using clear dark bottle method.Gross (GPP) ranged 9.28 467.07 mg C/m 3 /h; net (NPP) 3.09 248.13 respiration (R) 4.03 262.73 /h.GPP, NPP R are lowest summer, increasing peak spring.In summer winter, significantly positive correlations observed between GPP on one hand, phaeopigments other.In there is also a significant correlation dissolved oxygen concentration.In negative found conductivity salinity, GPP, other, with NPP.Spatial seasonal variations productivity depend environmental meteorological conditions each station, including water temperature, conductivity, nutrient inputs light availability.

The massive increase in the amount of greenhouse gases atmosphere, especially carbon dioxide (CO2), has had a significant impact on global climate. Research revealed that lakes play an important role cycle and they can shift between roles sources sinks. This study used Landsat satellite images to analyze spatiotemporal characteristics factors influencing CO2 changes Chagan Lake China. We conducted six water sampling campaigns at 2020–2021 determined partial pressure (pCO2) from 110 samples. surface reflectance was matched with events within ±7 days overpasses, yielding 75 pairs. A regression analysis indicated strong associations pCO2 both band difference model near-infrared green (Band 5-Band 3, R2 = 0.83, RMSE 27.55 μatm) exponential [((exp(b3) − exp(b5))2/(exp(b3) + exp(b5))2, 0.82, 27.99 μatm]. comparison performances linear machine learning found XGBoost highest fitting accuracy (R2 0.94, 16.86 μatm). Landsat/OLI acquired mainly 2021 map during ice-free period. showed considerable variability range 0–200 μatm. also seasonal variations, lowest mean values autumn (30–50 summer (120–150 μatm), respectively. Spatially, southeast were higher than those northwest. fluxes calculated based ranged −3.69 −2.42 mmol/m2/d, indicating absorbing (i.e., it weak sink). Temperature, chlorophyll a, total suspended matter, turbidity have reinforcing effects overall trend pCO2, while Secchi disk depth negatively correlated pCO2. results this provide valuable insights for assessing context climate change.
