- Does long term exposure of Tobacco Specific Nitrosamines (TSNAs) lead to negative health impacts.
- Previous research shows TSNAs stick to surfaces. TSNAs hard to measure due to reactivity (esp NNN, NNK).

- Added HONO enriched air to chamber with cloth coated with nicotine to create TSNA. Examined cellulose and cotton with/without sweat and skin oil.

- HONO deposition increase with nicotine addition.
HONO deposition may have been inhibited by water presence in cotton materials.
-TSNA increased in production in present of sweat and skin oil.
