Preservation of terrestrial fauna and flora has been the main reason for the settlement of most protected areas in the past 30 years, but although those areas may include water bodies, this does not necessarily mean that the biodiversity of freshwater environments are also protected. In the present study, the fauna inventory of eight streams (1st, 2nd, 4th and 5th orders) of three microbasins o...

Tumors of the liver, kidneys, and lungs have been induced in rats by the feeding of dimethyl nitrosamine (DMN) and diethylnitrosamine (DENA) (1, 11, 12, 18). Dontenwill et al. (3, 4) reported that squamous-cell carcinoma of the trachea and lung of Syrian hamsters followed ad ministration of DENA by each of three ap proaches—tube feeding, inhalation, and subcu taneous injection. They observed ...

The influence of pasteurization and sodium chloride, sodium ascorbate, polyphosphates and sodium nitrite coupled with pasteurization on nitrosamine contents in pork was studied. Nitrosamines: dimethylonitrosamine (DMNA) and diethylonitrosamine (DENA) were extracted from raw material, distilled, condensed in an evaporator under lowered pressure and analyzed chromatographically. An inhibitory eff...
