Untargeted Multiple Reaction Monitoring

Abstract. Multiple reaction monitoring (MRM) enables robust and sensitive quantification but traditionally requires predefined precursor–fragment transitio

Over 350,000 chemicals and mixtures are registered for production and use worldwide. We can routinely measure only a small fraction. That gap — between what we're exposed to and what we can detect — is basically why the exposome exists as a field. pubs.acs.org/esthag/artic...

Toward a Global Understanding of Chemical Pollution: A First Comprehensive Analysis of National and Regional Chemical Inventories

Abstract. Chemicals, while bringing benefits to society, may be released during their lifecycles and possibly cause harm to humans and ecosystems. Chemical

Hi Bluesky — I'm Mehedi, a PhD researcher in environmental analytical chemistry. I study the chemical exposome & metabolome with LC-HRMS. Here I'll share papers I read, method explainers, and honest PhD notes. Come say hi if you're into #exposome #massspec #envchem.
