This study investigated the fate of eight N-nitrosamines during membrane bioreactor (MBR) treatment. The results suggest that biodegradation is mainly responsible for the removal of N-nitrosamines during MBR treatment. Other removal mechanisms were insignificant (e.g. adsorption to sludge) or not expected (e.g. photolysis and volatilization) given the experimental conditions and physicochemical...
The carcinogenicity and mutagenicity of chemicals may be modulated by other chemicals, including those prepared by organic synthesis. Considering the several drawbacks of synthetic compounds vis-a-vis the human organism, the lignin biomass component was examined for this purpose. The binding affinity of lignin samples prepared by chemical and biological modification of lignin products derived f...
Abstract:N-nitrosaminesis a kind of poison which can induce cancer. Nitrite can react withsecondary amines to form N-nitrosamines in meat production. The objective of this experiment was to study N-nitrosamines formation ofthree kinds offermentationcelery powder (FCP506, FCP504, and FCP-homemade) and nitritein vitro nitrosation reaction system bydifferent pH, temperature, and the ratio of the s...
