The Role of Mass Spectrometry in Environmental Monitoring and Pollution Control
Environmental science relies heavily on mass spectrometry to identify and quantify pollutants at trace levels. Its unmatched sensitivity and selectivity make it a vital tool for ensuring air, water, and soil quality.
One of its primary applications lies in detecting persistent organic pollutants (POPs), including pesticides, dioxins, and industrial chemicals. Using techniques like GC-MS and LC-MS/MS, researchers can monitor pollutant levels in ecosystems, even at nanogram-per-liter concentrations.
In air quality analysis, portable mass spectrometers can measure volatile organic compounds (VOCs) and particulate matter composition in real time. This allows regulatory agencies to respond rapidly to industrial emissions or wildfire smoke.
In water testing, the device detects pharmaceutical residues, microplastics, and heavy metals. For soil contamination, isotopic mass spectrometry provides insights into pollutant sources and degradation pathways.
Advanced systems now integrate tandem mass spectrometry (MS/MS) for greater specificity, allowing separation and analysis of molecular fragments. This approach reduces false positives and improves quantification…
