| Abstract: |
| Sediments and particulate matters in aquatic environment take the roles of main carriers and final destinations of hydrophobic and lipophilic organic contaminants， which have been proved to be potential secondary pollution sources for releasing contaminants to aquatic environment again. Organic pollution in sediments and particulate matters is an important factor affecting the safety of aquatic environment. Therefore， it is essential to expand the screening scope of organic contaminants as wide as possible to understand and grasp the comprehensive pollution situation. Liquid chromatography－high resolution mass spectrometry（LC－HRMS） is suitable for the analysis of a wide range of organic pollutants from medium to strong polarity. Its application could not only realize the high-throughput analysis， but also expand the identification of unknowns. The researches on organic contaminants in sediments and particulate matters by LC－HRMS are reviewed in this paper， including the analysis strategies， the analysis process and the practical analysis on target， suspect and nontarget organic compounds， and the high-throughput analysis， screening of emerging contaminants， characteristics and applications of different databases， compound identification confidence level， data independence acquisition and prioritization strategies are focused. Meanwhile， the existing problems and prospects of LC－HRMS applications are summarized and addressed， so as to improve the identification efficiency and better carry out the screening and monitoring of organic contaminants in environmental samples. Furthermore， the relevant general content of HRMS involved in this article also provides a certain reference and inspiration for the applications of this technique in other fields. |
