1. Electronic Cigarettes: Helpful or Harmful? Jess Baldonado, Haley Delagnes Whitefish High School Mr. Spangler

2. Leading Question ● Should electronic cigarettes be legal to use in public? o How does the use of electronic cigarettes affect air quality? o Are the substances affecting the air harmful towards health?

3. Introduction ● Our interest was sparked by: o recent development of electronic cigarette industry o limited regulations o controversy of the topic  What is the vapor made of?  Is it harmful to health of clients?  Is it harmful to health of innocent bystanders?  What are the long term effects?

4. Background ● What does PM 2.5 mean? o It stands for Particulate Matter that is 2.5 pm in diameter or smaller. A strand of human hair is 60pm. ● What is the EPA limit for PM 2.5? o The maximum daily limit is 30-35 micrograms per cubic meter. Average annually is 13-14 micrograms. ● Health concerns related to PM 2.5? o There is a direct link from particulate matter and asthma. Since we spend the majority of our time indoors it is important we are breathing clean air. ● Percent of time indoors? o We spend typically 80% or more inside.

5. Background ● Hit public market in 2007, since then has created an annual revenue of $1 billion ● Electronic cigarettes don’t contain tobacco ● Electronic cigarette liquid “E-juice” o propylene glycol o nicotine o polyethylene glycol o concentrated flavors o vegetable glycerine

6. Background ● Nicotine o Damages osteoblasts (University of Texas) o Damages tissue around arteries (Brown University) o Leads to diseases such as atherosclerosis or PAD o Could result in amputation if gone untreated ● Propylene Glycol o Used in engine coolants and antifreeze o Provokes allergic reactions o Buildup in bloodstream leads to coma, convulsions, and heart problems (Joe King, M.S.)

7. Hypothesis ● Air quality PM levels would substantially rise while electronic cigarettes are in use.

8. Method ● Placed DustTrak where user regularly operates electronic cigarette ● Electronic cigarette was around 3 feet from DustTrak ● Compared PM levels from throughout the day to when the electronic cigarette was in use

13. Materials ● Vision Battery ● Aspire Cartomizer ● 12 mg/ml “E-Juice” o Cool Mint Menthol Flavoring o Purchased from eCig Vapor Juice Store in Kalispell

14. Vision Battery Aspire Cartomizer “E-Juice”

15. Results ● Start time: January 24, 2014 6:40 pm ● End Time: January 25, 2014 2:30 pm ● Ran DustTrak just under 18 hours ● Minimum PM levels were.003 mg/m^3 ● Maximum PM levels were 18.354 mg/m^3 ● Average PM levels were.105 mg/m^3

16. Results ● Electronic cigarette used from 10:00 pm to 10:30 pm ● Maximum PM level recorded at 10:18 pm ● PM levels were under recommended amount when electronic cigarette was not in use

17. Line Graph of Results

18. ● PM levels substantially rose during the use of electronic cigarette o 17,480 times greater than average PM level o 611,800 times greater than minimum PM level ● Proves hypothesis correct Discussion

19. Possible Errors ● Unrealistic proximity to DustTrak ● Changing variables damaging results o Animals o Cooking o Fire burning o Force of exhale

20. Conclusion ● The FDA should regulate where electronic cigarettes are allowed to be used o Electronic cigarettes severely raise PM levels in the air when in use o Harmful substances are being exhaled ● Electronic cigarettes can be beneficial o When used as a method to quit smoking o Not to be used as a gateway to bad behavior

21. Improvements ● Comparing PM levels of traditional cigarettes to electronic cigarettes ● Sampling vapor to understand exact substances it contains ● Comparing different nicotine levels ● Looking more in depth at the time it takes for PM levels to reach “normal”
