Abstract

The production and use of chemicals worldwide, and thus the number of those that can potentially leach into the environment, is constantly increasing. Recent advances in analytical techniques provide the opportunity to detect a wide range of contaminants in water that would not be detected by traditional targeted analysis (TA) methods. These advanced techniques include the use of high-resolution mass spectrometry (HRMS) or tandem HRMS in suspect screening analysis (SSA) or non-target analysis (NTA). This review presents the advances of the last five years for SSA and NTA of polar emerging contaminants (ECs) in various matrices, including drinking water, surface water, wastewater, and soil/sediment. We discuss all steps in the analytical procedure, including novel sampling and extraction approaches, GC or LC-HRMS analysis, (pre)data processing, evaluation, and reporting. We also identify challenges and future trends in SSA and NTA monitoring of polar ECs.
