Abstract
Abstract Nitrosamines are nitrogen-containing compounds that occur in trace amounts in everyday items. Tobacco-specific nitrosamines (TSNA) have been identified as some of the most potent carcinogens in tobacco products. The objective of this study was to evaluate market preparation conditions affecting TSNA levels in cured burley tobacco. The data for this study were based on a market-preparation experiment design to study bale density and size effects on TSNA levels during storage in Greenville, TN following the 2005, 2006, and 2007 growing seasons. Standard and flue-cured sized bales were evaluated at standard and high density levels. The effects of bale size and density were estimated by evaluating TSNA content changes between the baling and sale time. Analysis of variance (ANOVA) was performed for all the years combined. Results show that bale size and density do not have a significant effect on TSNA level changes.
期刊介绍：
Chinese Tobacco Science is an academic scientific journal (bimonthly) under the supervision of the Ministry of Agriculture and Rural Affairs of the People's Republic of China, and sponsored by the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences and the Qingzhou Tobacco Research Institute of China National Tobacco Corporation. It was founded in 1979 and is publicly distributed nationwide. The journal mainly publishes academic papers on scientific research results, new production technologies, and modern management in my country's tobacco science research and tobacco production technology. In addition, it also publishes forward-looking review articles in the field of tobacco research. There are columns such as tobacco genetics and breeding, cultivation technology, modulation and processing, physiology and biochemistry, plant protection, review or monograph, quality chemistry, etc.
