Previous work on the impact of cinnamon flavored electronic cigarette vapor on heart function during early development in zebrafish indicate chemical compounds in the vapor, aside from nicotine, can significantly affect heart function. To determine which compounds were present in the vapor used in our prior study, non-targeted, qualitative gas chromatography/mass spectrometry was performed. Nicotine was found to be present in the nicotine-containing vapor, and it was confirmed to be absent in the nicotine-free vapor. Other chemical compounds that may have affected cardiovascular function in zebrafish were also identified in the analyzed vapors including cinnamaldehyde and eugenol among others.

先前关于肉桂味电子烟蒸汽对斑马鱼早期发育期间心脏功能影响的研究表明，除了尼古丁之外，蒸汽中的化学化合物可以显著影响心脏功能。为了确定我们之前研究中使用的蒸汽中存在的化合物，进行了非目标、定性的气相色谱/质谱分析。结果发现，在含有尼古丁的蒸汽中有尼古丁存在，并确认不含尼古丁的蒸汽中没有尼古丁。此外，还识别出其他可能影响斑马鱼心血管功能的化学物质，包括肉桂醛和丁香酚等。
