“…This shows that although Jiangsu has strengthened the treatment of point source pollution and achieved results in COD pollution, the treatment of NH 4 -N emission is still insufficient. NH 4 -N, mainly coming from synthetic fertilizers, will reduce the concentration of dissolved oxygen in the water, leading to a decline in water quality and the death of aquatic plants and animals [54]. Jiangsu, as the province of thousands of lakes and rivers, needs to strengthen NH 4 -N pollution controls to protect the aquatic environment [55].…”

Excess consumption of water resources and environmental pollution have become major challenges restricting sustainable development in China. In order to prevent the pollution of water resources, policymakers should have reliable emission reduction strategies. This paper aims to contribute new knowledge by analyzing the spatial-temporal characteristics and driving forces of point source emission. The chemical oxygen demand (COD) and ammonia nitrogen (NH4-N) emission variations in 31 provinces and municipalities of mainland China during the years 2004–2017 are analyzed. The results obtained using the logarithmic mean Divisia index (LMDI) method indicate that: (1) the COD and NH4-N emission effects have similar temporal characteristics. Technology improvement and pollutant emission intensity are the main factors inhibiting the incremental COD and NH4-N emission effects, while economic development is the main driving factor of COD and NH4-N emission effects. Population increases play a relatively less important role in COD and NH4-N emission effects. (2) The spatial features of COD and NH4-N emission effects show differences among provinces and municipalities. The reduction of COD emission effects in each province and municipality is obviously better than that of NH4-N emissions. (3) In the eastern, central, and the western regions of China, the total COD emission effect shows a downward trend, while apart from the central region, the NH4-N emission effect appears to be rising in the east and west of China. Therefore, increasing investment into pollution treatment, promoting awareness of water conservation, strengthening technological and financial support from the more developed eastern to the less developed central and western regions, can help to reduce the COD and NH4-N emissions in China.

“…The content of ammonia (NH 3 ) in water is a global concern because of its very dangerous effects [28]. High ammonia content can cause a high number of fish deaths [29], increase white spot infections in fish [30], triggering damage to DNA levels for shrimp groups after exposure to ammonia for 48 hours.…”

The revitalization of the Sekanak River is one of the Palembang city government programs. Sekanak River is one of the oldest rivers in the city of Palembang that receives waste, from both industry and domestic so that the quality will experience pollution. The development of activities along the Sekanak River has affected river water quality. Decreased river water quality can be qualitative identified with the occurrence of changes in colour and odour. Some communities in the watershed area still use it for their daily needs. The current problem of decreasing the quality of river water in Sekanak requires chemical and physical examinations to anticipate the effects of environmental pollution. The study was conducted using a sample of water from the Sekanak River taken at 2 sample points close to human activities. The results showed that sample 1 showed several parameters that exceeded the quality standard while sample 2 that was located creek area was still in good condition. The physical parameters of the river point 1 water sample exceed the allowable limits for the Total Suspended Solids (TSS) and Total Dissolved Solids (TDS) parameters. For inorganic chemical parameters, the water sample at point 1 exceeds the allowed limits for the parameters of pH, ferrous (Fe) and lead (Pb) and sulphate ion content (SO4).

“…In an ERA, determination of toxicity, expressed as an EC50 (the half-maximal effective concentration) is the approach that is most often employed, but establishing the chronic toxic effects of the pollutant on organisms represents a more sophisticated level of analysis (Wen et al, 2018;Zhang et al, 2017). The sensitivity of a diversity of species towards environmental contaminants is another important factor when carrying out an ERA (Barron et al, 2012), in order to avoid either "insufficient" or "excessive" assessment (Zhang et al, 2017;Park et al, 2018).…”

The sensitivity of individual organisms towards toxic agents is an important indicator of environmental pollution. However, organism-specific quantification of sensitivity towards pollutants remains a challenge. In this study, we determined the sensitivity of Chlorella vulgaris (C. vulgaris) and Scenedesmus quadricauda (S. quadricauda) towards three ionic liquids (ILs), 1-alkyl-3-methyl-imidazolium chlorides [Cnmim][Cl] (n=4,6,8). We kept all external parameters constant to identify the biotic parameters responsible for discrepancies in species sensitivity, and used flow cytometry to determine four conventional endpoints to characterise cell viability and cell vitality. Our results demonstrate that after exposure to the ILs, cell proliferation was inhibited in both species. At the same time, the cell size, complexity and membrane permeability of both algae also increased.However, while Chl a synthesis by S. quadricauda was inhibited, that of C. vulgaris was enhanced. S. quadricauda has evolved a metabolic defense that can counteract the decreased esterase activity that has been shown to occur in the presence of ILs. 2While it is likely that S. quadricauda was less sensitive than C. vulgaris to the ILs because of this metabolic defense, this alga may also exhibit better membrane resistance towards ILs.
