The first symposium on Accurate Mass/High Resolution Mass Spectrometry for Environmental Monitoring & Remediation was held at ACS Spring 2017 in San Francisco. At the time, there were limited venues where sessions focused on the use of accurate mass/high-resolution mass spectrometers for environmental applications were held. Over one day and half, presenters shared their latest research mostly on suspect screening for the analysis of  PFAS, cyanotoxins, impact of fracking on water quality, understanding the fate of contaminants during biofiltration… with tools that now may seem obsolete. In the 5 years since that first symposium, advancements in the use of accurate mass/high-resolution mass spectrometers within environmental laboratories have dramatically grown with the help of new hardware and software. Several national and international projects, like the EPA’s ENTACT study and NIST’s MANTA program, aimed at evaluating the ability of non-targeted analysis laboratory methods to identify unknown chemicals consistently and correctly, enabled the broader implementation of this technique. At present, as it can be inferred from the number and scope of publications and conferences focused on the use accurate mass/high-resolution instrument, suspect screening and non-target analysis are routinely applied for environmental monitoring. In this presentation, we will provide an overview of how hardware, software and applications have evolved since the first symposium at ACS. We will also present new trends in the field and how groups, such as BP4NTA, are contributing to the development of this field.
