“…Large number of organic chemicals have been produced and released into the environment worldwide and the number is increasing (Bu et al, 2013). Adverse ecological and human health effects have been observed for these organic contaminants (OCs) (Long et al, 1995;Sharpe, 2001;Feron et al, 2002;Sharpe and Irvine, 2004).…”

a b s t r a c tA high throughout semi-quantification method for screening nearly 900 organic contaminants (OCs) in river sediments has been developed. For most OCs tested, concentrations calculated from the proposed semi-quantification method deviated from actual values by a factor of 4. The overall recovery tests indicated that most OCs can be successfully extracted from sediments with recovery rates from 84.1 to 128.6%. To demonstrate the effectiveness of our method towards OC quantification, we screened OCs from sediments collected from the Haihe River basin. Seventy unregulated OCs (including pesticides, flame retardants, PPCPs, etc.) were identified and quantified at concentrations up to 2600 ng/g from 24 sediment samples. From these results, it is confirmed that the developed method is a useful way to fulfill a comprehensive analysis of OCs in sediments and would be valuable for the identification and prioritization of priority pollutants in watershed management.

“…Thus, some type of prioritization or ranking is required in order to allocate monitoring efforts towards relevant target compounds (Ela et al 2011;Guillén et al 2012). A number of prioritization methods have been proposed for and applied to rank different organic compounds (Arnot and Mackay 2008;Muñoz et al 2008;Kumar and Xagoraraki 2010;Murray et al 2010;Daginnus et al 2011), and a detailed review was provided by Bu et al (2013).…”

“…These lists in China were mainly based on the existing priority lists in USA and Europe. These ranking approaches should be further developed for different situations covering different geographical regions, climates, demographics, and cultural backgrounds and should be designed in such a way that they account for the use practices, complex fate processes, and the specific modes of action associated with many chemicals (Boxall et al 2013;Bu et al 2013). …”

While more developed countries have a wellestablished systems to develop water quality criteria (WQC), little research has been done on the adequacy of the current WQC to protect endemic species of China. In order to maintain the health of aquatic ecosystems in China, a series of projects to establish national WQC based on regional characteristics has recently been initiated. However, the establishment of a completely novel methodology would be costly and time consuming. Also, due to the similarities in physiologies and natural histories of classes of aquatic organisms, there is no reason to believe that WQC would not be sufficient to protect unique species in China. This review was undertaken to identify key outstanding issues regarding establishment of aquatic life criteria (ALC) to be applied in China, including prioritization of chemicals, test species, mode of action, field/semi-field data, and methods of aggregating the information and calculating the ALC. This was used to identify the principle issues that need to be addressed in order to better understand the methods for development of criteria for the protection of aquatic life and provide a reference to China and other developing countries committed to the establishment of their own WQC system.

“…However, water managers have expressed uncertainty as to whether some remaining unregulated contaminants should be included in the regulations. The approaches applied to identify and prioritize unregulated contaminants were summarized in our previous review [9]. As an example, the United States Environmental Protection Agency (USEPA) publishes a Contaminant Candidate List (CCL) every five years under the authorization of the Safe Drinking Water Act [10].…”

The Danjiangkou reservoir was selected to provide the source water for the middle routes of the South to North Water Transfer Project, which has provoked many environmental concerns. To date, investigations of water contamination of the source water of the Danjiangkou reservoir with organic micro-pollutants have been limited. This study was conducted to identify and rank organic contaminants that pose risks in the Danjiangkou reservoir. To this end, the Chemical Hazard Evaluation and Management Strategies (CHEMS-1) approach was adapted to integrate the deconvolution technology of qualitative identifying contaminants for site-specific environmental matrices. The samples were screened for the presence of 1093 contaminants using deconvolution technologies and the hazard values of the identified contaminants were calculated using the adapted CHEMS-1 approach according to their hazardous properties and occurrence in source water. The results showed that 46 contaminants from 1093 targets were present in Danjiangkou water, 23 of which appeared at frequencies higher than 50%, and 15 of which were identified as priorities. Over half (53%) of the highranked contaminants were polycyclic aromatic hydrocarbons (PAHs), with chrysene ranked highest on the list. Health risk assessment of the top-ranked PAHs was conducted and revealed that cancer risks of PAHs detected in the source water of Danjiangkou to different populations ranged from 10 -7 to 10 -6, indicating a low cancer risk to consumers. The results of this study indicated that the adapted CHEMS-1 approach was feasible for site-specific screening of organic contaminants to identify and rank potential priority pollutants.
