Sampling Program: - Initiated in 2010 - Representative bales were selected and tagged at receiving station
for testing - Tagged bales were cored and samples were analyzed for TSNA

Relative Humidity Data Collection Relative humidity, specifically during the first few weeks of
curing, has been cited as a potential factor in TSNA formation
Relative humidity data were analyzed from the last week of August through the first week of October using http://www.wunderground.com
There were 9 to 38 weather stations within the tobacco production region for each receiving station
