Advancements in analytical chemistry have made it possible to detect emerging contaminants at very low concentrations. Techniques such as liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) are commonly used. These methods allow for the identification and quantification of contaminants in various environmental matrices, including water, soil, and air. The ability to detect these substances is a critical first step in assessing their potential health effects.
