“…Hydrocarbon input negatively affects the quantity of oxygen that can dissolve in the aquatic system, thereby creating an anoxic condition for aquatic biota ( Peirce et al., 1998 ; Muralikrishna and Manickam, 2017 ), hence the negative correlation observed between DO and TPH in both mediums. DO and temperature shows strong negatively correlated (r = -0.80∗); confirming that dissolved oxygen in the surface water is higher at lower temperature and vice versa ( Sheldon et al., 2019 ).…”

This study was designed to assess total petroleum hydrocarbon (THP) concentrations in the surface water and sediment sampled from Woji Creek and to assess potential ecological and human health risk due to petroleum hydrocarbons along the creek. Physicochemical parameters [pH, temperature (T), electrical conductivity (EC), dissolved oxygen (DO), total dissolved solids (TDS)] were in-situ measured from sediment and surface water; hydrological parameters (width, depth and volume) were used to calculate the flow rate (discharge) at different stations of the creek. Trend of TPH in the surface water samples along the creek were as follows: St4 (3.639 AE 1.121 mg/L) > St3 (2.449 AE 0.623 mg/L) > St1 (1.457 AE 0.244 mg/L) > St2 (1.069 AE 0.228 mg/L) > St5 (1.010 AE 0.120 mg/L) Trend of TPH concentration across the creek was as follows: St1 -8.758 AE 0.697 mg/kg > St3 -7.675 AE 0.541 mg/kg > St5 -5.515 AE 0.401 mg/kg > St4 -5.075 AE 0.363 mg/kg > St2 -3.162 AE 0.307 mg/kg. Diagnostic indices indicate that the hydrocarbon in the creek was from petrogenic source. Estimation of ecological risk indicated risk in the surface water but not in the sediment. However, human health risk assessment indicated no risk due to human ingestion of the sediment or surface water.

“…In the current work, the highest water temperature degrees were in summer and spring, which ranged between 25 and 28ºC at all sites of the examined governorates. Higher maximums of temperature ranges indicated poorer aquatic system health (Sheldon et al, 2019). This result was parallel to the dissolved oxygen (D.O.)…”

Water quality changes combined with rising atmospheric temperatures due to climate change may affect freshwater ecosystems. Thus, projected changes in global air temperature and rainfall could affect river flows inducing mobility and dilution of contaminants. On the other hand, the increasing water temperatures may affect chemical reaction kinetics, causing impairment in water quality and freshwater ecological status (Whitehead et al., 2009). Many authors studied the impacts of the climate change on environmental chemical pollutants (Whitehead et al., 2009; Balbus et al., 2013; Gouin

“…Urbanization is closely related to changes in water ecosystem services, and both national and international research results have shown that the rapid urbanization process leads to a serious decline in water regulation services (Sheldon et al 2019). Rapid urbanization and land use change are the main reasons for changes in the structure of urban ecosystems, and changes in the structure of urban ecosystems directly lead to a decline in ecosystem services (Daily et al 2009).…”

The urbanization process causes the increase of impervious surface, changes the underlying surface, material and energy cycle, and profoundly affects the urban ecosystem. Based on the hydrological process model, we constructed an evaluation framework for water ecosystem services. Taking the Jiuxiang River basin in Nanjing as an example, this study evaluates the process of urban impervious surface growth and hydrological cycle changes from 2000 to 2015, and reveals the impact of urbanization on water ecosystem services. The results showed that the impervious surface of the Jiuxiang River Basin in Nanjing increased rapidly from 2000 to 2015, and the impervious surface density increased from low to high. In the past 15 years, water supply services in urbanized areas have increased by 23.2%, while water regulation services and supply services have decreased by more than 20%, increasing the risk of urban waterlogging. Rapid urbanization changes the flux and stock in the water cycle process of urban ecosystems, which is the mechanism that leads to the decline of water ecosystem regulation services, support services and cultural services. The evaluation framework and technical method of water ecosystem services proposed in this study can provide theoretical basis and technical reference for water ecosystem services research and urban water ecosystem restoration.
