Decoding the chemical fingerprints of emerging contaminants

In today’s world, chemical and inorganic pollutants are becoming increasingly diverse, persistent, and difficult to detect. To meet this growing challenge, scientists are relying on mass spectrometry to unravel the complex signatures of emerging contaminants. This Accelerating Science Mass Spectrometry Feature page explores how advanced analytical techniques are enhancing our ability to detect and identify compounds across water, soil, air, food, and biological samples.

Here we cast the spotlight on contaminants such as per- and polyfluoroalkyl substances (PFAS), pesticides, pharmaceuticals and personal care products (PPCPs), endocrine disruptors, and other persistent organic pollutants. Often found at ultra-trace levels, these compounds pose significant obstacles for environmental monitoring and public health protection. The breakthrough innovations in mass spectrometry are opening new possibilities for scientists and regulatory agencies, equipping them with the precision and sensitivity needed to stay ahead and drive meaningful progress to protect both ecosystems and human health.

Continue reading to explore real-world applications, expert insights, and the cutting-edge technologies that are driving progress in contaminant detection and deepening our understanding to decode the chemical fingerprints of these emerging contaminants.
