Abstract This paper discusses the preparation of modified activated carbon (PAC-1) and its adsorption performance for nitrosodiethylamine (NDEA). The PAC-1 was characterized by SMS X-ray diffractometer, NDEA removal mechanism investigated. results showed that, compared with unmodified carbon, had a better effect after pre-soaking 0.8 mol/L permanganate (PM) 24 hours calcination at 400 °C 7 hour...

Previous studies have shown that a diet high in fat and marginally deficient in lipotropes enhances aflatoxin B] hepatocarcinogenesis and depresses hepatic drug metabolism in rats. In this study we have compared induction of tumors by jV-nitrosodimethylamine, ./V-nitrosodiethylamine, or jV-nitrosodibutylamine in normal or marginally lipotrope-deficient rats fed a high-fat diet. The deficiency s...

Nitroso compounds and their precursors in the environment, in certain occupational settings, in diet and also due to the use of tobacco products, cosmetics, pharmaceutical products as well as their endogenous formation in the human body from dietary components, may be potential risk factors in cancer, Nitrosamines, such as, N-nitrosodiethylamine (NDEA), one of the most important environmental c...
