stateside one worldStudent researchers at Rochester Institute of Technology’s National Technical Institute for the Deaf (RIT/NTID) are developing methods to analyse the effects of flavourings used in electronic cigarettes. In partnership with RIT’s Kate Gleason College of Engineering and the University of Rochester Medical Centre, the world’s first and largest technological college for deaf and hard-of-hearing students, is part of the team that has received a $329,000 grant from the National Institutes of Health.
Todd Pagano, associate professor/dean for Teaching and Scholarship Excellence, leads the NTID project alongside a team of deaf and hard-of-hearing student researchers. Risa Robinson, professor/department head in Mechanical Engineering and director of the Respiratory Technologies Laboratory in RIT’s Kate Gleason College of Engineering, is the investigator on the RIT portion of the grant. The study is part of a larger project to examine the DNA damage and inflammatory responses of cells exposed to e-cigs’.

The project titled; Emission Aerosol Constituents and Comparative Toxicology of Electronic Cigarettes with Flavourings will determine the chemicals present in e-cigarette emissions with chromatography-mass spectrometry (GC-MS), a type of instrumentation present in many laboratory settings.
“The GC-MS provides analysis of chemicals present in the e-cig’ liquid and we are able to then measure the realistic exposure from produced constituents as they become emissions after vaping” Pagano said. “We’re looking to determine what compounds are present before and after vaping and which might be potentially harmful.”
According to the CDC, e-cigarette use has tripled among middle/high school students in just one year and surpassed current use of every other tobacco product, including conventional cigarettes. There are as yet, no established production protocols to help ensure their safety. The aim of this project is to establish and rank e-cig’ flavourings by chemicals/hazard and to inform the FDA of the long-term adverse effects of existing and newer flavourings. Read full article
