The search for zero in environmental analysis: lessons learned, opportunities, and perspectives.



Organic compounds are ubiquitous in modern societies and the scientific literature shows that new compounds are being discovered at an increasing rate. Unfortunately, these chemicals ultimately end up in our air, rivers, and food. Consequently, today environmental analytical chemists face a multitude of challenges in understanding the intricate interactions between these contaminants and the natural environment’s abiotic and biotic components. Nowadays, one of the most powerful tools in the analytical arsenal of scientists is the mass spectrometer, which coupled to other modern analysis techniques has become a formidable instrument to study the occurrence and fate of contaminants at very low concentrations. In this presentation, I’ll discuss the progress of environmental analysis in recent years as well as different strategies that we have applied in the last 10 years to improve the discovery of new contaminants and their transformation products in surface waters.




Pedro A. Segura received his doctorate from the Université de Montréal in 2009, where he focused on developing innovative techniques for detecting antibiotics in environmental waters at ultra-low levels. He continued his research as a Postdoctoral Fellow at the St. Laurent Centre of Environment and Climate Change Canada and then at McGill University, where he utilized high-resolution mass spectrometry to investigate the occurrence and transformation of emerging contaminants. Since 2013, he has led a research group at the Department of Chemistry of Université de Sherbrooke, dedicated to enhancing our knowledge of the fate and impacts of organic contaminants in the environment.

Groupe de discussion en spectrométrie de masse de Montréal (GDSMM)

Le groupe de discussion sur la spectrométrie de masse de Montréal (GDSMM) est un organisme à but non lucratif qui offre un forum favorisant les interactions locales, nationales et internationales entre les scientifiques oeuvrant en spectrométrie de masse. Le GDSMM organise des séminaires scientifiques et des forums de discussion présentant les derniers développements en recherche fondamentale et appliquée en spectrométrie de masse. Une réunion annuelle du GDSMM qui regroupe les étudiants et les post-doctorants a lieu à Montréal chaque printemps et offre une opportunité unique de réseautage en plus d’accroitre la visibilité et la sensibilisation aux contributions locales en spectrométrie de masse.

Montreal mass spectrometry discussion group (MMSDG)

The Montreal mass spectrometry discussion group (MMSDG) is a not-for-profit organization that provides a forum to promote local, national and international interactions among scientists involved in mass spectrometry. MMSDG sponsors scientific seminars and forums to present the latest developments in basic and applied research in mass spectrometry. An annual MMSDG meeting that regroups students and postdoc is held every spring in Montreal, and provide a unique networking opportunity to participants and enhance the visibility and awareness of local contributions in mass spectrometry.
