Abstract In this study, organic compounds were screened in surface water collected from Xujiahe basin, China by gas chromatographymass spectrometry (GC–MS). A total of 51 compounds were identified including 14 organochlorine pesticides (OCPs), 9 organophosphorus pesticides (OPs), 16 polycyclic aromatic hydrocarbons (PAHs) and 12 chlorobenzene (CBs). The concentrations of OCPs, PAHs and CBs were generally low. The concentrations of OCPs in Xujiahe reservoir ranged from N.D. to 35.6 ng/L, the concentrations of PAHs ranged from N.D. to 19.8 ng/L and the concentrations of CBs ranged from 10.3 to 124.6 ng/L. The Ecological Structure Activity Relationships (ECOSAR) model was employed to directly predict the integrated toxicity indexes of 51 organic pollutants. The risk quotient (RQ) values of most of the organic compounds in the water samples were acceptable for their ecological risk. Keywords Xujiahe basin · Organic pollutant · Risk assessment · Toxicity values With the development of industry and agriculture and the improvement of living standards, more chemicals are used in life. Various chemical products such as medicines, agricultural fertilizers, herbicides and pesticides exist in the environment. Those chemicals through direct discharge of industrial wastewater and domestic sewage, as well as the soil leakage of agricultural chemicals, surface runoff and atmospheric deposition enter the environmental water body (Guo et al. 2014). Although toxic organic pollutants in environmental waters are present at comparatively low levels, they will accumulate in the human body and cause harm to the internal organs (López-Serrano et al. 2014; Wang Electronic supplementary material The online version of this article (https://doi.org/10.1007/s00128-020-02970-2) contains supplementary material, which is available to authorized users. * Shiwei Jin [email protected] 1

et al. 2018). In the 1970s, the US Environmental Protection Agency selected a total of 129 organic chemicals as priority pollutants, including 114 toxic organic substances. According to the characteristics of environmental pollution, China has also proposed a list of 68 environmental pollution pollutants. Due to a large variety of pollutants in the water environment, it is one of the key points for environmental management and governance to obtain the re
