A literature search was conducted in the PubMed, Embase, Web of Science, Google Scholar, and CNKI databases to identify emerging DBPs first reported in the past five years, collecting data on their identification and occurrence. While earlier studies primarily employed gas chromatography (GC) related methods, recent years have seen a substantial shift toward liquid chromatography (LC) related methods. Among the emerging DBPs reported over the past five years, GC related methods have identified four classes, whereas LC related methods have identified 26 classes. Furthermore, innovative techniques such as supercritical fluid chromatography-quadrupole-time of flight-tandem mass spectrometry (SFC-Q-TOF-MS/MS) have been introduced to enhance DBP identification. The reported concentrations of individual emerging DBPs are mostly in the range of 10¹ ng/L, typically only one-thousandth to one-tenth of those of regulated and priority DBPs, which generally exist at μg/L levels.

Green Analytical Procedure Index individually evaluates the sample preparation, the type of instrumental technique, the reagents and solvents employed, the health and safety hazard, occupational hazard, and waste of each proposed analytical tool. This literature review showed that Soxhlet extraction, although ranked lower in greenness, is still one of the most widely used techniques for total petroleum hydrocarbons determination due to its completeness. Techniques like gas chromatography - mass spectrometer coupled with solid-phase microextraction, and infrared based tools with direct application are greener because the use of solvent is negligible, and the preparation of the sample is minimal. At the same time infrared based techniques showed lower prediction accuracy compared to gas chromatography - mass spectrometer coupled with solid-phase microextraction. This review highlights the critical need to balance analytical performance with environmental sustainability, offering insights into future developments in forensic and environmental monitoring.
