متن کاملOccupational exposure to unburnt bidi tobacco elevates mutagenic burden among tobacco processors.
The nature of mutagenic burden due to occupational exposure to tobacco flakes and dust was determined among 20 female tobacco processors (TP) and 20 matched controls (C) by testing urinary mutagenicity in the Ames assay. In addition, urinary cotinine was estimated as a marker of tobacco absorption. Workers and controls were sub-divided into those with no tobacco habit (NH) and those habituated ...
