Emerging contaminants (ECs), encompassing pharmaceuticals, personal care products, pesticides, and industrial chemicals, represent a growing threat to ecosystems human health due their persistence, bioaccumulation potential, often-unknown toxicological profiles. Addressing these challenges necessitates advanced analytical tools capable of detecting quantifying trace levels ECs in complex environmental matrices. This review highlights the pivotal role mass spectrometry (MS) monitoring ECs, emphasizing its high sensitivity, specificity, versatility across various techniques such as Gas Chromatography-Mass Spectrometry (GC-MS), Liquid (LC-MS), High-Resolution Mass (HR-MS). The application MS has facilitated real-time detection volatile organic compounds, comprehensive non-targeted screening unknown contaminants, accurate quantification diverse matrices including water, soil, air. Despite effectiveness, matrix interferences, lack standardized methodologies, limited spectral libraries persist. However, recent advancements, hybrid systems integration artificial intelligence (AI), are paving way for more efficient predictive modeling contaminant behavior. Continued innovation technologies collaborative efforts essential overcome existing ensure sustainable solutions mitigating risks associated with emerging contaminants.
