Emerging Chemicals of Concern in Evolving Electronic Nicotine Delivery Systems

Principal Investigators: Binnian Wei

Funding Mechanism: NIH Grant

ID number: 1R21ES030028-01

Award Date: 9/19/2018

Institution: Roswell Park Cancer Institute Corp

Because electronic nicotine delivery systems (ENDS) contain plastic, glass and metal parts as well as e-liquids, they may contain a number of emerging chemicals of concern (ECCs), including phthalates, phenolic compounds, and flame retardants, that have been associated with adverse health outcomes such as asthma, endocrine disruption, reproductive and developmental abnormalities, and carcinogenic activity. The goal of this study is to characterize the types and levels of these chemicals in ENDS products, using various rigorous and reproducible analytical methods. Study aims are: (1) to characterize the contamination of e-liquids with ECCs by identifying the types and levels of ECCs in e-liquids; (2) to identify and measure the types and levels of ECCs in certain parts of ENDS, including refillable cartridge/tanks, as well as mouthpieces, which are potential ECC exposure sources; (3) to characterize thes types and levels of ECCs in ENDS aerosols; and (4) to examine and characterize the similarities and differences in types and levels of ECCs in e-liquids, extracted samples, and ENDS aerosols. Findings may inform future regulatory activities related to ENDS products.
