Tobacco-specific nitrosamine adducts: studies in laboratory animals and humans.

abstract：:This paper examines behavioral changes in natural populations of wildlife associated with pollution. Although some changes such as lack of nest attentiveness and decreased nest defense have been noted, the results have not been consistent and have been difficult to relate to specific pollutants. Experimental studies i...
