Abstract |
Micropollutants including pharmaceuticals, personal care products, pesticides, etc., and their transformation products (TP) are widely distributed in environmental media. However, limited information on their occurrence and concentration is available, at least partially due to lack of precise, reliable analytical tools. Recently, highly advanced instrument such as high resolution mass spectrometry (HRMS) has been commercially available and applicable for the detection of micropollutants and TPs. In addition, HRMS relevant screening techniques, suspect and nontarget screening, have been developed and optimized to identify unpredictable and unknown pollutants at trace levels. In this review paper, prior micropollutants and their TPs are suggested via literature survey, and the procedure of target/suspect/nontarget screening for their identification are introduced in detail with technical steps. Finally, the applicability of HRMS-based identification methods is discussed with lessons from previous studies. Considering the accuracy and applicability, suspect/nontarget screening approaches with HRMS are expected to extend our knowledge on micropollutants and TPs under the cover. |
