“…These levels are similar to that at Su Tai (266 ± 48 ng L − 1 , but there the fraction of flame retardants was lower (16%). Previous research has also reported frequent detection of organophosphorus flame retardants, e.g., in Yangtze River water [23] and river water in Sweden [24]. Since the use of brominated flame retardants is decreasing because of environmental and human health risks, organophosphorus flame retardants has become widely produced and used since the 1970s [8].…”

Background The vast occurrence of organic micropollutants in surface waters has raised concerns about drinking water safety and public health. The Tai Hu Basin region in China, a typical developing and populous area, is facing the challenge of water pollution. To ensure drinking water safety, the knowledge on how treatment techniques and raw water quality affect the quality of finished water must be improved. The aim of the current study was to evaluate drinking water quality in relation to source water origin and treatment strategies. Five drinking water treatment plants (DWTPs), using three different source waters in the Tai Hu River Basin, (i) Yangtze River, (ii) Wetland River Network, and (iii) Lake Tai Hu, were studied by analyzing 291 micropollutants in raw and finished water.Results Major differences in water characteristics were observed among the source waters. The dominating group of micropollutants in the River Network was pesticides, while Yangtze was mainly polluted by flame retardants. The total concentration of poly- and perfluoroalkyl substances (PFASs) in Tai Hu water was far higher than in others. In total, 51 compounds were detected in finished water, with an overall average total concentration of 730 ± 160 ng L -1 . The removal efficiency of the detected compounds in the DWTPs averaged 24 ± 149%, which highlights the major challenge for the DWTPs to remove emerging organic micropollutants through current treatment processes.Conclusions Our study showed that if the source water contains high levels of PFASs and organophosphorus flame retardants, even advanced treatment procedures are inefficient in removing the micropollutants, and the finished water may contain cumulative levels in the mg L -1 range. On the other hand, if pesticides and pharmaceuticals dominate, high overall treatment efficiencies may be obtained if using advanced treatment techniques. DWTPs are advised to use advanced treatment techniques or alternative water sources to guarantee the safety of drinking water. As surface water systems are highly impacted by upstream activities, efforts should also be made in the comprehensive water sector for improved surface water quality.

“…While traditional target analysis often addressed only a limited number of contaminants, NTS now allows an "all-in-one" measurement and data can be directly used for target screening of hundreds to thousands of chemicals in monitoring studies [32,33]. Examples are the screening for about 270 and 400 target chemicals in order to evaluate the impact of non-treated and treated wastewater effluents on the micropollutant burden in water in the River Danube [34,35] and in small streams in Switzerland [36], respectively.…”

Currently, chemical monitoring based on priority substances fails to consider the majority of known environmental micropollutants not to mention the unexpected and unknown chemicals that may contribute to the toxic risk of complex mixtures present in the environment. Complementing component-and effect-based monitoring with widescope target, suspect, and non-target screening (NTS) based on high-resolution mass spectrometry (HRMS) data is recommended to support environmental impact and risk assessment. This will allow for detection of newly emerging compounds and transformation products, retrospective monitoring efforts, and the identification of possible drivers of toxicity by correlation with effects or modelling of expected effects for future and abatement scenarios. HRMS is becoming increasingly available in many laboratories. Thus, the time is right to establish and harmonize screening methods, train staff, and record HRMS data for samples from regular monitoring events and surveys. This will strongly enhance the value of chemical monitoring data for evaluating complex chemical pollution problems, at limited additional costs. Collaboration and data exchange on a European-to-global scale is essential to maximize the benefit of chemical screening. Freely accessible data platforms, inter-laboratory trials, and the involvement of international partners and networks are recommended.

“…Because of water pollution in Dianchi Lake, the value of climate regulation and pollution purification decreased by 87% and 32%, respectively, from 2010 to 2013 (Hu 2015). Both metals and ECs showed the accumulation and amplification potentials along the food chain (Gan 2010;Islam et al 2015;Peng et al 2018b;Zhang et al 2018). A study on the sediment of Dongjiang Port in Tianjin showed that the enrichment factor of arsenic was the highest, with a maximum value of 1.59 (Guo et al 2010).…”

Industrial development has brought China both opportunities and challenges since the reform and opening up in 1978. Spatial and temporal analysis showed that rapid industrialization has made eastern China under a more serious pollution stress. The most serious effects of industrial pollution were reflected in aquatic and soil ecosystem degradation, and damage can be observed from species, population, and community to ecosystem level. Public consciousness about contaminated sites rose from 2004 leading to greater efforts in ecological remediation, monitoring, and risk governance. Considerable efforts are still needed in expanding the extent and breadth of monitoring to explore where the greatest ecological risks lie and how to control them. Ecology of industrial pollution has become a popular discipline in China and will be further developed to help achieve the Sustainable Development Goals. Future research for a better ecological risk management should be focused on multi-media transfer and effects of mixed pollutants, mechanisms for clean energy and material flow, and integration of ecological risk with human health risk.
