The two hexachloroethane (HC)-based smoke formulations studied consisted of HC/Zn/2,4,6-trinitrotoluene (TNT) and HC/Zn. In the in vitro tests, human bronchial epithelial cells were exposed to the smokes at various concentrations. The responses studied were acute toxicity (viability of cells, trypan blue exclusion method) and genotoxicity (DNA single-strand(More)
Incapacitating and irritating agents produce temporary disability persisting for hours to days after the exposure. One can be exposed to these agents occupationally in industrial or other working environments. Also general public can be exposed in special circumstances, like industrial accidents or riots. Incapacitating and irritating agents discussed in(More)
Two red phosphorus (RP)-based smokes (P60 and RPB), differing from each other mainly in RP content and in type of additive, were evaluated for in vitro cytotoxicity (cell viability by the trypan-blue exclusion method) and genotoxicity (comet assay) by exposing BEAS 2B human bronchial epithelial cells to the smokes in a laboratory-scale chamber for 5 min.(More)
