Webinar Series: Analysis of Emerging Contaminants
Available on demand
Part I: Identification of Iodinated Disinfection Byproducts by GC-MS/MS
Most iodine-containing disinfection byproducts have been shown to be much more toxic than chlorinated and brominated counterparts, and to date only a few of them have been characterized in disinfection byproduct mixtures. During this webinar, Dr Cristina Postigo, Post-Doctoral Fellow at the Institute for Environmental Assessment and Water Research (IDAEA-CSIC), will describe how novel GC-MS technology can be used to uncover and potentially identify these unknown compounds. In addition to describing how disinfection byproduct mixtures were produced at lab-scale and the parameters of the analysis, she will also explain the workflow that was used to characterize the iodinated disinfection byproducts from the high resolution accurate mass data obtained.
Watch the webinar to learn:
- How to produce disinfection byproduct mixture concentrates from lab-scale disinfection reactions
- How to use high resolution accurate mass data to characterize volatile and semi-volatile molecules containing iodine
Part II: Emerging Contaminant Studies in Environmental Biotechnology using High Resolution LC-MSDuring this webinar, Dr Krista Wigginton, Assistant Professor at the Department of Civil and Environmental Engineering, University of Michigan, will discuss the use of high resolution LC-MS to understand the chemical fate of biomolecule pollutants, such as waterborne viruses and plasmids containing antibiotic resistance genes, in drinking water and wastewater treatment processes. Dr Wigginton will also describe the quantification of unregulated disinfection by-products in drinking water, and the identification of organic contaminants adsorbed to microplastics deployed in the Great Lakes using HRMS.
Watch the webinar to learn:
- How to study the fate of biomolecules in drinking and wastewater using LC-HRMS
- Methods for the LC-HRMS quantification of unregulated disinfection byproducts
- The kinetics of viral RNA and capsid protein oxidation during disinfection treatments
